Can I Buy Methimazole Over The Counter
Methimazole prescription medication, also known as thiamazole and marketed under the brand name Tapazole, is used in treating an overactive thyroid gland, or hyperthyroidism. Methimazole's mechanism of action is to block the production of thyroid hormone rather than affecting existing thyroid hormone. Methimazole medication works by blocking an enzyme known as thyroperoxidase which is necessary for T3 and T4 hormone synthesis.

Methimazole medication is soluble in water and is found as a white, crystalline substance. Methimazole is broken down in the liver after oral administration and excreted in the urine. Some medical providers prescribe methimazole with a starting daily dosage in adults of methimazole 5 mg per day but the dose prescribed depends on the judgement of the provider and the health needs of the patient. Methimazole tablets are oral, white to off white tablets that contain methimazole 5 mg or methimazole 10 mg and other inactive ingredients. Methimazole tablets should be stored at 15 C to 30 C. Methimazole is affordable at under 30 cents per pill at many pharmacies. Methimazole coupons may be available online and the cost of thiamazole tablets may also be covered by many insurance plans.
Methimazole is a medication that needs to be prescribed by a licensed medical provider to be dispensed by a pharmacy in the United States. As a result, one cannot obtain methimazole OTC (over-the-counter) medication or buy methimazole online. People in need of a methimazole prescription can connect with a licensed medical provider through Push Health who prescribe methimazole tablets, including generic methimazole 10 mg and methimazole 5 mg medication, when appropriate to do so.
Methimazole prescription medication use, as is the case with other thyroid medications, can result in side effects. Side effects from methimazole use include sore throat, skin rash, fever, headache and malaise. Methimazole can also cause agranulocytosis. People who have had a hypersensitivity or allergic reaction to methimazole should not use it. Methimazole and alcohol should not be used together. Questions about possible side effects related to methimazole medication use should be directed to one's medical provider and pharmacist.
In very rare situations, methimazole can temporarily lower the number of white blood cells in your blood, which increases the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:
Yes, hair loss (alopecia) is listed as a side effect of methimazole (brand name: Tapazole) and other thyroid medications. Your hair loss or hair thinning may also be a symptom of hyperthyroidism, when your thyroid gland is overactive and makes too much thyroid hormone.
This list is not complete. Other drugs may interact with methimazole, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed in this medication guide.

One way to treat a cat with hyperthyroidism is with an oral medication that contains methimazole. The medication can be given life-long or to stabilize the cat before other treatment options, such as radioactive iodine therapy or surgery.
Methimazole affects the production of thyroid hormone and is useful in treating conditions related to thyroid hormone, especially thyrotoxicosis. Thus, it is considered a thyroid blocking agent. This activity reviews methimazole's indications, interactions, adverse effects, and other pharmacodynamic and pharmacokinetic factors. In addition, it highlights the role of the interprofessional team in improving care for patients receiving methimazole for conditions where it has an indicated therapeutic value.

Methimazole (MMI) is an anti-thyroid drug that belongs to drug class thionamides. The primary mechanism of action of methimazole is to block thyroid hormone production from the thyroid gland. It interferes with the step that causes the iodination of tyrosine residues in thyroglobulin, mediated by the enzyme thyroid peroxidase, thus preventing the synthesis of thyroxine (T4) and triiodothyronine(T3).[4]
An additional mechanism is by inhibiting the iodotyrosyl residues from the coupling. Methimazole may also interfere with the oxidation of the iodide ion and iodotyrosyl groups. Eventually, thyroglobulin gets depleted, and circulating thyroid hormone levels decrease. It may also help to control diseases by affecting the overall immune system. Various studies show the reduction of immune molecules like intracellular adhesion molecule 1, soluble interleukin 2, and anti-thyrotropin receptor antibody over time, thus alleviating immune-related hyperthyroid issues.[5] Whether or not the improvements in the patient profile are due to this or the improvement of thyroid function remains unclear.
In a drug overdose, initiate supportive therapy as per the patient's condition. Consider the possibility of multiple drug overdose and drug-drug interactions. Ensure patient's airway, support ventilation, and hemodynamic stability. Monitor for serum electrolytes, blood gases, and patient's vitals. Consider giving activated charcoal to decrease the absorption of the medicine from the stomach before it reaches peak plasma concentration.
Physicians, nurses, and pharmacists in many parts of the world continue to use methimazole because of its effectiveness and low cost for treating hyperthyroidism (mainly for Graves disease). However, it is essential to know the side effects of methimazole, particularly severe drug allergy when taken with multiple medications, and side effects with the use of any thioamide medication in general. Furthermore, it is imperative to counsel the patient about rare side effects like agranulocytosis or liver failure before starting the medication.
In general, methimazole prescribing should be from an endocrinologist, with patient monitoring by the primary care provider and nurse practitioner. Dose changes must not occur without first consulting with the endocrinologist. The pharmacist should verify all dosing, perform mediation reconciliation, and report any concerns to the healthcare team. Nursing can verify medication compliance along with the pharmacist, as well as observe for any adverse effects. It is essential to communicate openly with all interprofessional team members to improve patient safety and better patient outcomes associated with methimazole use.[Level V]
In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.

---If possible, use flushable litter for the next 3 weeks. Otherwise use scoopable litter and collect all waste in a sturdy container lined with two plastic bags (one placed inside the other). Store waste in a well-ventilated space away from your primary living areas, and hold for an additional 2 weeks so natural decay will reduce radioactivity to background levels. Then the litter may be disposed with the normal trash. Landfills do not allow the disposal of low-level radioactive waste and are equipped with sensitive radiation detectors. You may be charged over $1000 if radioactivity is detected in your cat's litter at the landfill.
---Do not allow your cat to eat from your plate or walk on counter tops where food is prepared. If the cat does or you are not sure, then put on disposable gloves and thoroughly wash the area with soap and water before preparing food.
---If your cat salivates on hard surfaces, then these areas should be cleaned often with soap and water, or a spray cleaner (e.g., Formula409). For surfaces that are difficult to clean (e.g., couches and upholstered chairs) cover these surfaces with a towel or blanket and replace as necessary. These towels and blankets should be washed separately from your clothing using standard laundry detergents.
Due to potential inhibition of vitamin K activity by methimazole, the activity of oral anticoagulants (e.g.,warfarin) may be increased; additional monitoring of PT/INR should be considered, especially beforesurgical procedures.
Although there have been reports of hepatotoxicity (including acute liver failure) associated withTAPAZOLE, the risk of hepatotoxicity appears to be less with methimazole than with propylthiouracil,especially in the pediatric population. Symptoms suggestive of hepatic dysfunction (anorexia, pruritis,right upper quadrant pain, etc.) should prompt evaluation of liver function (bilirubin, alkalinephosphatase) and hepatocellur integrity (ALT, AST). Drug treatment should be discontinued promptly inthe event of clinically significant evidence of liver abnormality including hepatic transaminase valuesexceeding 3 times the upper limit of normal. 041b061a72
