Thyroid medications are usually prescribed to those who have a thyroid problem and need to feel normal again. Your metabolism and overall health can be impacted if your thyroid gland does not produce the right amount of hormones.
Thyroid drugs are recommended to treat conditions such as hypothyroidism, hyperthyroidism, thyroid cancer, or goiter.
The thyroid gland mainly produces two hormones: T3 (triiodothyronine) and T4 (thyroxine). T4 is the hormone that is most frequently prescribed as a medicine because the body converts it into T3 as required. A healthy thyroid is necessary for maintaining your metabolism, energy levels, heart rate, and even mood.
The only reliable way to diagnose whether your thyroid gland is underactive or overactive is by taking blood tests, which can help your provider decide the right treatment for you.
Why Thyroid Medications Matter
Thyroid medications work differently depending on the condition being treated. Basically, these drugs provide synthetic hormones to your body.
In cases of hypothyroidism, when your thyroid gland fails to produce enough hormone, drugs such as levothyroxine are recommended to restore your energy and other normal body functions. They are normally taken once a day, preferably in the morning, on an empty stomach, for better absorption.
But for hyperthyroidism, where your thyroid gland secretes too much hormone, you are given thyroid medications that lower thyroid hormone production and control symptoms such as a rapid heartbeat, anxiety, and weight loss.
After a thyroid surgery, hormone replacement therapy is used to keep your hormone levels in a normal range and prevent the thyroid gland from being overstimulated.
Regardless of the situation, you should always take your medication daily and have regular blood tests to make sure that your medicine is working and you are taking the proper dose.
Common Thyroid Medications
1. Levothyroxine (Synthroid, Levoxyl, Euthyrox)
It is mainly used for the treatment of hypothyroidism. Besides that, it also helps to shrink enlarged thyroid glands or goiters. This drug is a synthetic version of the thyroid hormone T4, which the body changes into the active hormone T3 to control metabolism, energy, and other functions.
The drug is generally taken once a day on an empty stomach, about 30-60 minutes before the first meal, to facilitate proper absorption. You should not take calcium or iron supplements together with this drug, as they will interfere with its absorption.
This medication can only be obtained with a doctor’s prescription. Levothyroxine is available in both solid and liquid dosage forms, with the main brand names being Synthroid, Levoxyl, and Euthyrox. Tablets are the most common form and come in different dosage strengths (e. g., 25, 50, 75, 100, 125, 150, 175, 200 µg) to allow doctors to make the most accurate dose adjustment.
Periodic blood tests are essential to adjust the dosage and keep hormone levels at the right level.
The side effects of levothyroxine are usually mild, but its over-dosage can cause symptoms such as palpitations, anxiety, or insomnia.
2. Liothyronine (Cytomel)
Your provider may prescribe you liothyronine to treat hypothyroidism if you are one of those cases that need faster symptom relief or are not responding well to levothyroxine alone.
Liothyronine is available in tablet form, mostly sold under the brand name Cytomel with doses of 5, 25, and 50 micrograms.
Your provider sometimes combined it with levothyroxine to get better symptom control. It is also used to manage myxedema, which is a very severe form of hypothyroidism.
It is generally recommended that you take it once daily or divide it into several doses as per your doctor’s instructions.
Side effects:
- If the dose is too high, it can cause increased heartbeat, palpitations, anxiety, sweating, or even insomnia.
- Other side effects can be headache, diarrhea, or weight loss.
- Only in very rare cases, an excessive dose strain the heart, especially in elderly people.
3. Combination therapy
Combination therapy is basically a mixture of levothyroxine (T4) and liothyronine (T3). If you still experience hypothyroid symptoms despite normalizing your T4 levels using only levothyroxine, your provider will recommend a combination therapy.
Its dosage should be taken with caution to prevent over- or under-treatment.
This drug is taken once daily, sometimes divided into two or three doses depending on symptoms and the doctor’s instructions.
- An overdose of this medication can result in hyperthyroid symptoms, such as a rapid heartbeat, anxiety, and insomnia
- On the other hand, under-dosing might cause tiredness
4. Anti-Thyroid Medications (Methimazole, Propylthiouracil)
These medications are used in the treatment of hyperthyroidism. They are ideal for lowering the production of excess thyroid hormone. Usually prescribed in the case of Graves disease, toxic nodules, and other disorders that lead to hyperthyroidism.
It is also sometimes used to prepare patients for radioactive iodine therapy or surgery. Hypothyroidism medications include Methimazole, Propylthiouracil (PTU), or carbimazole.
Methimazole and PTU slow your thyroid hormone production, helping control symptoms such as rapid heartbeat, anxiety, weight loss, and tremors. PTU also blocks the conversion of T4 to the more active T3, which further reduces hormone activity.
Its typical side effects are nausea, skin irritation, joint pain, or some rare but very serious consequences, such as liver failure or a weakened immune system.
If you experience any strange symptoms, inform your doctor right away.
5. Betta Blockers
Beta-blockers are medications that do not cure thyroid disease itself, but they help you live your normal life comfortably by suppressing the hyperthyroid symptoms. They are recommended alongside anti-thyroid drugs, which work to bring your hormone levels back to normal.
Hyperthyroidism can lead to symptoms such as rapid heartbeat, palpitations, anxiety, tremors, and excessive sweating. Beta-blockers decrease your heart rate and help to relieve these symptoms, thus making you feel more relaxed and at ease.
These drugs come in the form of tablets and are marketed under the brand names Propranolol or Atenolol. You may be instructed to take one or more doses per day, depending on the prescription. Your provider will advise you on the proper dose and timing based on your symptoms and heart rate.
Its side effects may incudes Fatigue, dizziness, or cold hands or feet.
Natural Ways to Manage Your Thyroid
Medications are a must for most thyroid conditions. However, you also need to follow certain natural strategies to help your thyroid function.
- Eat more iodine, rich foods. Seaweed, fish, and dairy are some of the foods that will help your body create hormones.
- Take more Selenium: You can get this from Brazil nuts, fish, and eggs. It helps in hormone conversion.
- Get enough zinc. Zinc is involved in your hormone production and immune system balance. Oysters, pumpkin seeds, lentils, and beef are some zinc-rich foods.
- Get more iron: Iron is involved in thyroid hormone production. Good sources include lean red meats, spinach, beans, and fortified cereals.
- Keep your gut healthy: A healthy gut helps with nutrient absorption and immune balance, which can boost your thyroid function. Fiber-rich foods and fermented foods like yogurt and kimchi are good for your gut.
- Be careful with certain vegetables: Raw broccoli, cabbage, and other cruciferous veggies can sometimes affect how your thyroid uses iodine. However, mild cooking decreases their impact, and they stay nutritious.
- Take care of your mental health: Stress can lead to a hormone imbalance. Yoga, meditation, mindful breathing, and deep relaxation can help keep your thyroid and other hormones in balance.
Please note that natural strategies can help your thyroid, but they cannot replace your prescribed thyroid medications.
