重要安全信息
禁忌
MINOCIN®（二甲胺四环素）注射是禁忌的谁已经表明过敏任意四环素或任何产品配方的组分的人。
警告
牙齿发育
MINOCIN®，像其他四环素类抗菌药物，可当给予孕妇致胎儿危害。如果有任何四环素妊娠期间使用，或者同时服用这些药物患者成为妊娠，应告知患者潜在危害胎儿。药四环素类的牙齿发育（妊娠，婴儿期，儿童期和到8岁的后半）期间使用可能会导致牙齿（黄灰棕）的永久变色。
在长期使用的药物的这种不利反应是比较常见，但已经观察到以下重复的短期课程。釉质发育不全也有报道。四环素类药物，因此，不应该被牙齿发育过程中使用，除非其它药物都不太可能是有效或禁忌。
骨骼发育
所有四环素类形成任何骨组织形成稳定的复合钙。在腓骨增长率下降已给出剂量25毫克口服四环素早产人类婴儿被观察/kg，每六个小时。这个反应被证明是可逆当药物被中断。
动物研究的结果表明，四环素穿过胎盘，被发现在胎儿组织，并且可以具有对胎儿（往往涉及到骨骼发育迟缓）的毒性作用。胚胎毒性的证据已经注意到在怀孕早期治疗的动物。
皮肤病反应
药物皮疹伴嗜酸细胞增多和全身症状（DRESS），包括死亡病例的报道与米诺环素的使用。如果这种综合征是公认的，药物应立即停药。
反合成代谢作用
四环素的抗合成代谢作用可导致增加的BUN。虽然这不是在那些与肾功能正常，患者显著功能受损的问题，四环素的较高的血清水平可能导致氮质血症，高磷血症和酸中毒。在这种条件下，监测肌酸酐和BUN的建议，并且每日总剂量不应超过24小时内200毫克。如果肾损伤存在，甚至通常的口服或非肠道剂量可能导致药物的全身性累积和可能的肝毒性。
光敏性
光敏性通过夸张的反应晒伤已经体现在一些人服用四环素类药物被观察到。这已被报道与米诺环素。
中枢神经系统的影响
已有报道中枢神经系统副作用包括头晕，头昏，眩晕。患者谁遇到这些症状时，应告诫驾驶车辆或使用危险机器，而在米诺环素治疗。这些症状可在治疗过程中消失，并且通常迅速消失当药物被中断。
艰难梭菌相关性腹泻
艰难梭菌相关性腹泻（CDAD）已被报道与使用的几乎所有的抗菌剂，包括MINOCIN®，并可能严重程度范围从轻度腹泻至致命性结肠炎。如果是CDAD疑似或确诊，持续抑菌使用不针对难辨梭状芽孢杆菌可能需要停产。
颅内高压
颅内高压（1H，假性脑瘤）一直与使用四环素类，包括美满霉素相关联。 IH的临床表现包括头痛，视力模糊，复视，视力和损失;视乳头水肿可在眼底镜检查被发现。育龄妇女谁是超重或有IH的历史是在发展四环素相关IH更大的风险。应避免同时使用异维A酸和美满霉素，因为异维甲酸也是已知造成假性脑瘤。
尽管IH停药后一般可以解决，存在的可能性永久性视力丧失。如果在治疗过程中出现视觉障碍，提示眼科检查是必要的。由于颅内压力停止用药后患者继续上升数周应监测，直到他们稳定下来。

SPL UNCLASSIFIED SECTION
MINOCIN®
Minocycline For Injection
100Mg/Vial Intravenous
Rx Only
To reduce the development of drug-resistant bacteria and maintain the effectiveness of MINOCIN® (minocycline) Injection and other antibacterial drugs, MINOCIN® (minocycline) injection should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria.
DESCRIPTION
MINOCIN, minocycline for injection, a sterile formulation of a semisynthetic derivative of tetracycline, is 4,7-Bis(dimethylamino)-1,4,4a,5,5a,6,11,12a-octahydro-3,10,12,12a- tetrahydroxy-1,11-dioxo-2-naphthacenecarboxamide monohydrochloride.
Its structural formula is:

Each vial, dried by cryodesiccation, contains minocycline HCl equivalent to 100 mg minocycline. When reconstituted with 5 mL of Sterile Water for Injection USP the pH ranges from 2.0 to 2.8.
Close
CLINICAL PHARMACOLOGY
Following a single dose of Minocin 200 mg administered intravenously to 10 healthy male subjects, serum concentrations of minocycline ranged from 2.52 to 6.63 mcg/mL (average 4.18 mcg/mL) at the end of infusion and 0.82 to 2.64 mcg/mL (average 1.38 mcg/mL) after 12 hours. In a group of 5 healthy male subjects, serum concentrations of minocycline ranged from 1.4 to1.8 mcg/mL at the end of the dosing interval following administration of Minocin 100 mg every 12 hours for three days. When Minocin 200 mg once daily was administered for three days, serum concentrations of minocycline were approximately 1 mcg/mL at 24 hours. The serum elimination half-life of minocycline following administration of either Minocin 100 mg every 12 hours or 200 mg once daily was not significantly different and ranged from 15 to 23 hours.
The serum elimination half-life of minocycline ranged from 11 to 16 hours in subjects with hepatic impairment (n=7) and 18 to 69 hours in subjects with renal impairment (n=5). In comparison, the serum elimination half-life of minocycline ranged from 11 to 17 hours following a single dose of oral minocycline 200 mg in healthy subjects (n=12).
Microbiology Mechanism of Action
The tetracyclines are primarily bacteriostatic and are thought to exert their antimicrobial effect by the inibition of protein synthesis. The tetracyclines, including minocycline, have a similar antimicrobial spectrum of activity against a wide range of Gram-positive and Gram-negative bacteria. Cross-resistance of these bacteria to tetracyclines is common.
List of Microorganisms
Minocycline has been shown to be active against most isolates of the following bacteria, both in vito and in clinical infections as described in the INDICATIONS AND USAGE section:

Gram-negative Bacteria
Bartonella bacilliformis
Brucella species
Klebsiella granulomatis
Campylobacter fetus
Francisella tularensis
Vibrio cholerae
Yersinia pestis
Acinetobacter species 
Enterobacter aerogenes

Susceptibility Test Methods When available, the clinical microbiology laboratory should provide the results of in vitro susceptibility test results for antimicrobial drugs used in resident hospitals to the physician as periodic reports that describe the susceptibility profile of nosocomial and community-acquired pathogens. These reports should aid the physician in selecting an antibacterial drug for treatment.
Dilution Techniques
Quantitative methods are used to determine antimicrobial minimal inhibitory concentrations (MICs). These MICs provide estimates of the susceptibility of bacteria to antimicrobial compounds. The MICs should be determined using a standardized method (broth or agar) or equivalent with standardized inoculum concentrations and standardized concentrations of tetracycline or minocycline powder.1,2 The MIC values should be interpreted according to the criteria provided in Table 1.
Diffusion techniques
Quantitative methods that require measurement of zone diameters also provide reproducible estimates of the susceptibility of bacteria to antimicrobial compounds. The zone size provides an estimate of the susceptibility of bacteria to antimicrobial compounds. The zone size should be determined using a standardized method.2,3 This procedure uses paper disks impregnated with 30 mcg tetracycline or 30 mcg minocycline to test the susceptibility of microorganisms to minocycline. The disk diffusion interpretive criteria are provided in Table 1.

a Organisms that are susceptible to tetracycline are also considered susceptible to minocycline. However, some organisms that are intermediate or resistant to tetracycline may be susceptible to minocycline.
b The current absence of resistance isolates precludes defining any result other than “susceptible”. If isolates yielding MIC results other than susceptible, they should be submitted to a reference laboratory for further testing.
A report of “Susceptible” indicates that the antimicrobial drug is likely to inhibit growth of the microorganism if the antimicrobial compound reaches the concentrations usually achievable at the site of infection. A report of “Intermediate” indicates that the result should be considered equivocal, and, if the microorganism is not fully susceptible to alternative, clinically feasible drugs, the test should be repeated. This category implies possible clinical applicability in body sites where the drug is physiologically concentrated or in situations where high dosage of drug can be used. This category also provides a buffer zone which prevents small uncontrolled technical factors from causing major discrepancies in interpretation. A report of “Resistant” indicates that the antimicrobial drug is not likely to inhibit growth of the microorganism, if the antimicrobial drug reaches the concentrations usually achievable at the site of infection; other therapy should be selected.
Quality Control
Standardized susceptibility test procedures require the use of laboratory controls to monitor and ensure the accuracy and precision of supplies and reagents used in the assay, and the techniques of the individuals performing the test 1,2,3. Standard tetracycline (class compound) or minocycline powder should provide the following range of MIC values noted in Table 2. For the disc diffusion technique, using the 30 mcg tetracycline or 30 mcg minocycline disk, the criteria in Table 2 should be achieved.

When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
CONTRAINDICATIONS
This drug is contraindicated in persons who have shown hypersensitivity to any of the tetracyclines or to any of the components of the product formulation.
WARNINGS
Tooth Development
MINOCIN, like other tetracycline-class antibacterials, can cause fetal harm when administered to a pregnant woman. If any tetracycline is used during pregnancy, or if the patient becomes pregnant while taking these drugs, the patient should be apprised of the potential hazard to the fetus. The use of drugs of the tetracycline class during tooth development (last half of pregnancy, infancy, and childhood to the age of 8 years) may cause permanent discoloration of the teeth (yellow-gray-brown).
This adverse reaction is more common during long-term use of the drugs but has been observed following repeated short-term courses. Enamel hypoplasia has also been reported. Tetracycline drugs, therefore, should not be used during tooth development unless other drugs are not likely to be effective or are contraindicated.
Skeletal Development
All tetracyclines form a stable calcium complex in any bone-forming tissue. A decrease in the fibula growth rate has been observed in premature human infants given oral tetracycline in doses of 25 mg/kg every six hours. This reaction was shown to be reversible when the drug was discontinued.
Results of animal studies indicate that tetracyclines cross the placenta, are found in fetal tissues, and can have toxic effects on the developing fetus (often related to retardation of skeletal development). Evidence of embryotoxicity has been noted in animals treated early in pregnancy.
Dermatologic Reaction
Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) including fatal cases have been reported with minocycline use. If this syndrome is recognized, the drug should be discontinued immediately.
Anti-anabolic Action
The anti-anabolic action of the tetracyclines may cause an increase in BUN. While this is not a problem in those with normal renal function, in patients with significantly impaired function, higher serum levels of tetracycline may lead to azotemia, hyperphosphatemia, and acidosis. Under such conditions, monitoring of creatinine and BUN is recommended, and the total daily dosage should not exceed 200 mg in 24 hours (See DOSAGE AND ADMINISTRATION). If renal impairment exists, even usual oral or parenteral doses may lead to systemic accumulation of the drug and possible liver toxicity.
Photosensitivity
Photosensitivity manifested by an exaggerated sunburn reaction has been observed in some individuals taking tetracyclines. This has been reported with minocycline.
Central Nervous System Effects
Central nervous system side effects including light-headedness, dizziness or vertigo have been reported. Patients who experience these symptoms should be cautioned about driving vehicles or using hazardous machinery while on minocycline therapy. These symptoms may disappear during therapy and usually disappear rapidly when the drug is discontinued.
Clostridium difficile Associated Diarrhea
Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including MINOCIN®, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.
C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibacterial use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.
If CDAD is suspected or confirmed, ongoing antibacterial use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated.
Intracranial Hypertension
Intracranial hypertension (IH, pseudotumor cerebri) has been associated with the use of tetracyclines including Minocin. Clinical manifestations of IH include headache, blurred vision, diplopia, and vision loss; papilledema can be found on fundoscopy. Women of childbearing age who are overweight or have a history of IH are at greater risk for developing tetracycline associated IH. Concomitant use of isotretinoin and Minocin should be avoided because isotretinoin is also known to cause pseudotumor cerebri.
Although IH typically resolves after discontinuation of treatment, the possibility for permanent visual loss exists. If visual disturbance occurs during treatment, prompt ophthalmologic evaluation is warranted. Since intracranial pressure can remain elevated for weeks after drug cessation patients should be monitored until they stabilize.
PRECAUTIONS
General As with other antibacterial preparations, use of this drug may result in overgrowth of nonsusceptible organisms, including fungi. If superinfection occurs, the antibacterial should be discontinued and appropriate therapy instituted.
Hepatotoxicity has been reported with minocycline; therefore, minocycline should be used with caution in patients with hepatic dysfunction and in conjunction with other hepatotoxic drugs.
Incision and drainage or other surgical procedures should be performed in conjunction with antibacterial therapy when indicated.
Prescribing MINOCIN® Injection in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.
Information for Patients Patients should be counseled that antibacterial drugs including MINOCIN® (minocycline) Injection should only be used to treat bacterial infections. They do not treat viral infections (eg, the common cold). When MINOCIN® (minocycline) Injection is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by MINOCIN® (minocycline) Injection or other antibacterial drugs in the future.
Diarrhea is a common problem caused by antibacterials which usually ends when the antibacterial is discontinued. Sometimes after starting treatment with antibacterial drugs, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as two or more months after having taken the last dose of the antibacterial. If this occurs, patients should contact their physician as soon as possible.
Laboratory Tests Periodic laboratory evaluation of organ systems, including hematopoietic, renal, and hepatic studies should be performed.
All patients with gonorrhea should have a serologic test for syphilis at the time of diagnosis. Patients treated with minocycline should have a follow-up serologic test for syphilis after 3 months.
Drug Interactions Because tetracyclines have been shown to depress plasma prothrombin activity, patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage.
Since bacteriostatic drugs may interfere with the bactericidal action of penicillin, it is advisable to avoid giving tetracyclines in conjunction with penicillin.
The concurrent use of tetracyclines and methoxyflurane has been reported to result in fatal renal toxicity.
Concurrent use of tetracyclines with oral contraceptives may render oral contraceptives less effective.
Administration of isotretinoin should be avoided shortly before, during, and shortly after minocycline therapy. Each drug alone has been associated with pseudotumor cerebri (See PRECAUTIONS).
Increased risk of ergotism when ergot alkaloids or their derivatives are given with tetracyclines.
Drug/Laboratory Test Interactions False elevations of urinary catecholamine levels may occur due to interference with the fluorescence test.
Carcinogenesis, Mutagenesis, Impairment of Fertility Dietary administration of minocycline in long-term tumorigenicity studies in rats resulted in evidence of thyroid tumor production. Minocycline has also been found to produce thyroid hyperplasia in rats and dogs. In addition, there has been evidence of oncogenic activity in rats in studies with a related antibacterial, oxytetracycline (ie, adrenal and pituitary tumors). Likewise, although mutagenicity studies of minocycline have not been conducted, positive results in in vitro mammalian cell assays (ie, mouse lymphoma and Chinese hamster lung cells) have been reported for related antibacterials (tetracycline hydrochloride and oxytetracycline). Segment I (fertility and general reproduction) studies have provided evidence that minocycline impairs fertility in male rats.
Pregnancy Teratogenic Effects: Pregnancy Category D (See WARNINGS)
All pregnancies have a background risk of birth defects, loss, or other adverse outcome regardless of drug exposure. There are no adequate and well-controlled studies on the use of minocycline in pregnant women. Minocycline, like other tetracycline-class antibacterials, crosses the placenta and may cause fetal harm when administered to a pregnant woman. Rare spontaneous reports of congenital anomalies including limb reduction have been reported in post-marketing experience. Only limited information is available regarding these reports; therefore, no conclusion on causal association can be established. If minocycline is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus.
Nonteratogenic Effects (See WARNINGS)
Labor and Delivery The effect of tetracyclines on labor and delivery is unknown.
Nursing Mothers Tetracyclines are excreted in human milk. Because of the potential for serious adverse reactions in nursing infants from tetracyclines, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother. (See WARNINGS.)
Pediatric Use Minocycline is not recommended for use in children below 8 years of age unless the expected benefits of therapy outweigh the risks (See WARNINGS).
Geriatric Use Clinical studies of intravenous minocycline did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy (See WARNINGS, DOSAGE AND ADMINISTRATION).
MINOCIN® IV (sterile minocycline hydrochloride, USP) does not contain sodium.
ADVERSE REACTIONS
The following adverse reactions have been observed in patients receiving tetracyclines.
Body as a whole: Fever, and discoloration of secretions.
Gastrointestinal: Anorexia, nausea, vomiting, diarrhea, dyspepsia, stomatitis, glossitis, dysphagia, enamel hypoplasia, enterocolitis, pseudomembranous colitis, pancreatitis, inflammatory lesions (with monilial overgrowth) in the oral and anogenital regions. These reactions have been caused by both the oral and parenteral administration of tetracyclines.
Genitourinary: Vulvovaginitis.
Hepatic toxicity: Hyperbilirubinemia, hepatic cholestasis, increases in liver enzymes, fatal hepatic failure, and jaundice. Hepatitis, including autoimmune hepatitis, and liver failure have been reported (See PRECAUTIONS).
Skin: Alopecia, erythema nodosum, hyperpigmentation of nails, pruritus, toxic epidermal necrolysis, and vasculitis, maculopapular and erythematous rashes. Exfoliative dermatitis has been reported. Fixed drug eruptions have been reported. Lesions occurring on the glans penis have caused balanitis. Erythema multiforme and Stevens-Johnson syndrome have been reported. Photosensitivity is discussed above (See WARNINGS). Pigmentation of the skin and mucous membranes has been reported.
Local Reactions: Injection site erythema and injection site pain.
Respiratory: Cough, dyspnea, bronchospasm, exacerbation of asthma, and pneumonitis.
Renal toxicity: Interstitial nephritis. Elevations in BUN have been reported and are apparently dose related (See WARNINGS). Acute renal failure has been reported.
Musculoskeletal: Arthralgia, arthritis, bone discoloration, myalgia, joint stiffness, and joint swelling.
Hypersensitivity reactions: Urticaria, angioneurotic edema, polyarthralgia, anaphylaxis/anaphylactoid reaction (including shock and fatalities), anaphylactoid purpura, myocarditis, pericarditis, exacerbation of systemic lupus erythematosus, and pulmonary infiltrates with eosinophilia have been reported. A lupus-like syndrome and serum sickness-like reactions also have been reported.
Blood: Agranulocytosis, hemolytic anemia, thrombocytopenia, leukopenia, neutropenia, pancytopenia, and eosinophilia have been reported.
Central Nervous System: Convulsions, dizziness, hypesthesia, paresthesia, sedation, and vertigo. Pseudotumor cerebri (benign intracranial hypertension) in adults and bulging fontanels in infants (See PRECAUTIONS - General). Headache has also been reported.
Other: Thyroid cancer has been reported in the post-marketing setting in association with minocycline products. When minocycline therapy is given over prolonged periods, monitoring for signs of thyroid cancer should be considered. When given over prolonged periods, tetracyclines have been reported to produce brown-black microscopic discoloration of the thyroid gland. Cases of abnormal thyroid function have been reported.
Tooth discoloration in pediatric patients less than 8 years of age (see WARNINGS) and in adults has been reported.
Oral cavity discoloration (including tongue, lip, and gum) have been reported.
Tinnitus and decreased hearing have been reported in patients on MINOCIN® (minocycline for injection).
The following syndromes have been reported. In some cases involving these syndromes, death has been reported. As with other serious adverse reactions, if any of these syndromes are recognized, the drug should be discontinued immediately:
Hypersensitivity syndrome consisting of cutaneous reaction (such as rash or exfoliative dermatitis), eosinophilia, and one or more of the following: hepatitis, pneumonitis, nephritis, myocarditis, and pericarditis. Fever and lymphadenopathy may be present.
Lupus-like syndrome consisting of positive antinuclear antibody; arthralgia, arthritis, joint stiffness, or joint swelling; and one or more of the following: fever, myalgia, hepatitis, rash, and vasculitis.
Serum sickness-like syndrome consisting of fever; urticaria or rash; and arthralgia, arthritis, joint stiffness, or joint swelling. Eosinophilia may be present.
OVERDOSAGE
The adverse events more commonly seen in overdose are dizziness, nausea, and vomiting.
No specific antidote for minocycline is known.
In case of overdosage, discontinue medication, treat symptomatically, and institute supportive measures. Minocycline is not removed in significant quantities by hemodialysis or peritoneal dialysis.
DOSAGE AND ADMINISTRATION
THE USUAL DOSAGE AND FREQUENCY OF ADMINISTRATION OF MINOCYCLINE DIFFERS FROM THAT OF THE OTHER TETRACYCLINES. EXCEEDING THE RECOMMENDED DOSAGE MAY RESULT IN AN INCREASED INCIDENCE OF SIDE EFFECTS.
Note: Rapid administration is to be avoided. Parenteral therapy is indicated only when oral therapy is not adequate or tolerated. Oral therapy should be instituted as soon as possible. If intravenous therapy is given over prolonged periods of time, thrombophlebitis may result.
For Pediatric Patients above 8 years of Age
Usual pediatric dose: Initial dose of 4 mg/kg, then 2 mg/kg every 12 hours, not to exceed the usual adult dose
Adults
Usual adult dose: Initial dose of 200 mg, then 100 mg every 12 hours and should not exceed 400 mg in 24 hours. The cryodesiccated powder should be reconstituted with 5 mL Sterile Water for Injection USP and immediately further diluted to 500 mL to 1,000 mL with Sodium Chloride Injection USP, Dextrose Injection USP, Dextrose and Sodium Chloride Injection USP, Ringer’s Injection USP, or Lactated Ringer’s Injection USP, but not with other solutions containing calcium because a precipitate may form especially in neutral and alkaline solutions. When further diluted in 500 mL to 1,000 mL of compatible solutions (except Lactated Ringer’s), the pH usually ranges from 2.5 to 4.0. The pH of MINOCIN® IV 100 mg in Lactated Ringer’s 500 mL to 1,000 mL usually ranges from 4.5 to 6.0.
Final dilutions (500 mL to 1,000 mL) should be administered immediately but product and diluents are compatible at room temperature for 24 hours without a significant loss of potency. Any unused portions must be discarded after that period.
The pharmacokinetics of minocycline in patients with renal impairment (CLCR <80 mL/min) have not been fully characterized. Current data are insufficient to determine if a dosage adjustment is warranted. The total daily dosage should not exceed 200 mg in 24 hours in patients with renal impairment. However, due to the anti-anabolic effect of tetracyclines, BUN and creatinine should be monitored (See WARNINGS).

ANIMAL PHARMACOLOGY AND TOXICOLOGY
Minocycline hydrochloride has been observed to cause a dark discoloration of the thyroid in experimental animals (rats, minipigs, dogs, and monkeys). In the rat, chronic treatment with minocycline hydrochloride has resulted in goiter accompanied by elevated radioactive iodine uptake and evidence of thyroid tumor production. Minocycline hydrochloride has also been found to produce thyroid hyperplasia in rats and dogs
