How Do I Take Antithyroid Medicine
Getting the right balance of thyroid hormone in your blood can take time.
Doctors have two main methods of trying to get the balance right. The first involves taking an initial high dose of carbimazole to reduce the amount of thyroxine in your blood. This dose is taken until the hormone levels in your blood have stabilised, usually about four to eight weeks later. Because your body needs a certain amount of thyroxine to function properly, the high dose is then slowly decreased. Usually, your hormone levels will be checked by a blood test every month or so. The dose of medicine you are taking will be changed depending upon the results of your thyroid hormone levels. The aim of this treatment is to keep you on the lowest level of antithyroid medicine necessary. This treatment method is called ‘titration’.
It can be difficult for a doctor to judge just the right dose of carbimazole to give in each case. Too much treatment may make the thyroxine level go too low. Not enough treatment means the level remains higher than normal. This is the reason for the regular blood tests and careful monitoring.
The second option is to deliberately take a high dose of carbimazole each day. This stops the thyroid gland making any thyroxine. Your doctor can then prescribe a daily dose of thyroxine to keep the blood level of thyroxine normal. This ‘over-treatment’ coupled with taking replacement thyroxine is called ‘block and replace’ and is a popular option.
How Thyroid Medication Treats Hypothyroidism
Medication for hypothyroidism aims to replace the hormone that the thyroid cant produce.
Hypothyroidism can be caused by an autoimmune disorder, surgical removal of the thyroid, or as a side effect of radioactive iodine treatment. These medications relieve the symptoms by providing you with the right amount of thyroid hormone.
Compounded T4 And T3 Thyroid Medication
This list of medications doesnt necessarily have a specific name but its important for you to realize that your doctor can write a prescription that contains any amount of T4 or T3 using a compounding pharmacy.
A compounding pharmacy is a special type of pharmacy that can create medication combinations that normal pharmacies cant.
Your doctor can have your medication created using different inactive ingredients, they can change a prescription to be applied to your skin instead of being taken by mouth, and so on.
This is important for your thyroid for several reasons:
The first has to do with the fact that your doctor can individually dose the amount of T4 and T3 based on what your body needs.
NDT comes in a set amount of 38mcg of T4 to 9mcg of T3 in each grain.
But what if you cant tolerate the 9mcg of T3? What if you need more or less?
Thats where compounding pharmacies come into play.
Your Doctor can write a prescription that contains 50mcg of T4 and 5mcg of T3.
They can write a prescription that contains 50mcg of T4 and 30mcg of T4 or any combination.
This gives both you and your doctor flexibility to find what works best for your body while reducing the number of capsules/pills that you need to take.
One of the major drawbacks to using this route is that compounding pharmacies are often more expensive than traditional pharmacies.
Because of the cost, its often better to try and find your ideal dose

Does Thyroid Cause Urination

An excess of thyroid hormones can cause diarrhea because they affect the gastrointestinal tract. Kidney function may also be impacted, resulting in more frequent urination. If youre feeling thirsty and frequently urinating, you may need to have your blood tested for diabetes.
Hypothyroidism has been shown to impair urinary concentration. We studied nine patients aged 42.7 years with severe hypothyroid and TSH-suppressed symptoms in our study. When the patient switched to levothyroxine treatment, the serum creatinine level was significantly higher. As a result, this group of patients had a significantly lower rate of filtration. Hypothyroidism caused rat urine dilution to be impaired after water loading in rats due to a nonosmotic release of vasopressin, which impairs urine dilution. This defect can be reversed with the use of levothyroxine as a treatment. To investigate the ability of patients with differentiated thyroid cancer to concentrate in urine for the first time, this study used existing studies.
The Urinary Effects Of Hypothyroidism
Hypothyroidism, which occurs when the thyroid gland produces less thyroid hormone, is usually chronic. When this happens, a variety of symptoms, including urinary problems, can occur. Urinary retention could be the culprit in hypothyroidism, and frequent inding of hyponatremia from an unknown source necessitates thyroid hormone testing. Thyroid disease, which can manifest as urinary symptoms such as frequent urination and slow urine flow, is a significant cause of urological symptoms in both men and women. Graves disease, on the other hand, can manifest as urinary symptoms as early as childhood. Dehydration can also affect your bladder, particularly during the day and at night.

Signs Your Thyroid Medication Is Working
You will know your thyroid medication is working if your symptoms decrease. You may experience more energy or an overall better quality of life.
This lessening of symptoms should not be accompanied by new ones. It should take only days to see improvement. However, your hormone levels may take months to level out fully.
Agranulocytosis: A Rare But Serious Complication
Another extremely rare, but serious, complication of antithyroid medications is known as agranulocytosis. Researchers have yet to discover what exactly causes agranulocytosis, but they do know that is a reaction characterized by attacking immune cells, called granulocytes. These cells protect the body from outside “invaders,” such as bacteria. Without granulocytes, the body is defenseless against bacteria and infection.
Agranulocytosis occurs more in patients taking PTU than Tapazoletwice as often, in fact. Regardless of their dosage, patients taking PTU have the same risk of developing the condition. With Tapazole, on the other hand, the risk is likely dependent on the dosage. The lower the dose, the lower the risk.
If you notice any infectioneven if it’s as ordinary as a sore throatseek immediate medical treatment. Again, agranulocytosis is an extremely rare complication of antithyroid medications, but it’s important to understand all the risks. You should have regular follow-up with your doctor while you are on these medications.

Do Overactive Thyroid Medications Have Side Effects
All medications have the potential to cause side effects. If your doctor prescribes a hyperthyroidism drug, they feel the benefits outweigh your risks. Call your healthcare provider right away if you experience any unusual symptoms while taking medication for an overactive thyroid.
Propylthiouracil side effects
Propylthiouracil can cause severe liver damage. If you cannot tolerate methimazole or other hyperthyroidism treatments like surgery or radioactive iodine, your doctor may prescribe this drug. If you’re pregnant, your doctor may also prescribe propylthiouracil during your first trimester, as methimazole may cause congenital disorders when taken during early pregnancy.
You should call your doctor right away if you experience itching, dark or foamy urine, stools that are lighter than normal, your eyes or skin appear yellow, or you develop pain in the upper right side of your stomach while taking propylthiouracil.
Other side effects of propylthiouracil include hair loss, a diminished sense of taste, unusual sensations in your hands or feet like numbness or tingling, unexplained pain in your joints or muscles, dizziness, and swelling in your neck.
Methimazole side effects
Agranulocytosis
Overactive thyroid medications can cause an extremely rare but serious condition called agranulocytosis. The most common symptoms of agranulocytosis are a high fever and sore throat. The condition can also cause mouth sores, a cough, and chills.
Can You Name Some Situations Where Your Doctor May Recommend Brand Over Generic Drug
If your provider is concerned that you are not responding as you should to a generic medicine or your response is not consistent, they may suggest you use a brand name drug. This may happen more often in certain situations such as in pregnancy, in very young babies, thyroid cancer, celiac disease or other malabsorption such as after gastric bypass. If you are allergic to the inactive ingredient in one generic or brand drug, you can be switched to another form with a different inactive ingredient. Repeating the thyroid labs 6-8 weeks after switching the medication is advised to ensure the effectiveness of the new drug.

Does Hypothyroidism Affect Urine Output
Because of Na+K+-2Cl* cotransporter upregulation and other solutes, including water, the sodium-delivered molecule may be delivered to the blood more easily in this environment. Hyponatremia, or an inability to excrete water, is frequently caused by a lack of water excretion, which is a common side effect of hypothyroidism.
Does Levothyroxine Cause Frequent Urination

You should report any symptoms such as increased thirst/urination, shakiness, unusual sweating, dizziness, or hunger to your doctor as soon as possible.
I recently became hypo and began taking Levo 25mg daily. My bladder started telling me to go to the toilet within 15-20 minutes of each time I urinate, which I only do occasionally. Within two days, I began experiencing frequent urination my bladder has started telling me to go to the toilet frequently. I dont believe I have UTI but I will have it looked at. How can I deal with this problem like any other person? Is it something that will pass as one gets used to the medications? Winjy crashed and burned on NDT at first, but I eventually realized I could tolerate small amounts hourly.
A conversion from Levo to NDT requires both published formulas and an independent conversion. If you start out really low no more than 15mg per day and work up to 15mg every two weeks, you should be fine. It will not only ruin your lungs if you take 60mg of salbutamol straight up. You have to choose whether you want NDT or Levo, which gives you the best life possible. If you have been unable to take sufficient thyroid supplements, you will experience complete depletion of your bodys and endocrine systems. B12 is produced by your muscles and fat. Your body will respond if it is necessary.

Are Thyroid Drugs Safe
Thyroid medicines are safe when taken at the recommended dose and prescribed by a doctor. You must ONLY take what your doctor recommends. The correct dosage for you is based on your age, health, current natural thyroid hormone levels, and weight.
When you first start treatment for hypothyroidism, your doctor will regularly monitor the levels of different thyroid hormones in your blood to determine if your dosage of thyroid medication needs adjusting. Once the correct dosage has been established for you, the frequency of these blood tests will decrease. Thyroid drugs are generally taken for life.
It will take a few months for your thyroid levels to get back to normal but as long as you are taking your thyroid drugs as prescribed, then you should not have many side effects. Side effects generally happen because you are taking too much thyroid hormone.
Thyroid hormones should NEVER be taken by people without thyroid problems to treat obesity or for weight loss. Some fatalities have occurred when they have been used if these drugs are taken in large dosages for this indication.
Also, talk to your doctor about your diet. Some people with hypothyroidism are particularly sensitive to the effects of iodine, and it may trigger or worsen hypothyroidism. In addition, high fiber diets and certain types of foods such as soy or cruciferous vegetables may affect how your body responds to thyroid drugs.
How Does Antithyroid Medication Work
Thyroxine is a body chemical made by the thyroid gland. It is carried around the body in the bloodstream. It helps to keep the body’s functions working at the correct pace. Many cells and tissues in the body need thyroxine to keep them working correctly.
‘Hyperthyroidism’ means an overactive thyroid gland. When the thyroid gland is overactive it makes too much thyroxine. The extra thyroxine causes many of the body’s functions to speed up.
Thionamides such as carbimazole reduce the amount of hormone released by the thyroid gland. Carbimazole does not affect the thyroxine which is already made and stored, but reduces further production. Therefore, it may take four to eight weeks of treatment for your thyroxine level to come down to normal.
