What is Synthroid?

If you have been diagnosed with hypothyroidism, your doctor may prescribe Synthroid medication. This oral medication contains Levothyroxine, a man-made hormone that replaces or provides more of the hormones that are usually produced by the thyroid gland. This butterfly-shaped gland is located in the front of the neck and the hormones it produces control how the cells in your body use energy from the food you eat. Your metabolism affects your heartbeat and body temperature as well as how you burn calories.

The thyroid gland normally produces and releases two hormones: thyroxine (T4) and tri-iodothyronine (T3). The thyroid mainly produces T4, which is then converted to T3 in tissue and organs. These hormones are responsible for maintaining a normal rate of metabolism in the body.

If the thyroid gland is unable to produce normal amounts of thyroxine, the level of both thyroid hormones in the blood decreases. This condition, known as hypothyroidism, results in a reduced metabolic rate, which leads to symptoms such as weight gain, intolerance to cold, constipation, dry skin, forgetfulness, depression, and fatigue. There is no cure for hypothyroidism but daily Synthroid, along with periodic blood tests, can help control thyroid hormone levels.

Conditions treated by Synthroid

Hypothyroidism may result from Hashimoto's disease, an autoimmune disorder that can lead to an enlarged thyroid, called a goiter. Your pituitary gland and thyroid gland work together in such a way that if a low hormone level is sensed, your pituitary gland will produce more thyroid stimulating hormone (TSH). If your thyroid is under attack from Hashimoto's disease, it cannot produce more hormones and begins to enlarge instead.

Synthroid may also be prescribed to treat or prevent a goiter which can be caused by hormone imbalances, radiation treatment, surgery, or cancer.

What to know before taking Synthroid

  • Tell your physician about any conditions you have and any medications you take, including non-prescription medication, vitamins, and supplements. If you are pregnant or nursing, your doctor may have to adjust your Synthroid dosage, but it is not expected to be harmful to your baby.

    If you have heart disease, diabetes, pituitary or adrenal gland problems, or trouble with blood clotting, then tell your doctor before starting Synthroid.

  • You should take your daily Synthroid dose at least 30 minutes before eating breakfast or having a caffeine-containing drink such as tea or coffee. Foods and drinks can reduce the absorption of Synthroid and make it less effective.

  • Antacids can also make Synthroid less effective, so it's advised that don't you take any at least four hours prior to or after taking Synthroid.

  • Let your physician know if you experience any side effects while taking Synthroid.

Possible Synthroid side effects

As with all prescription drugs, there are potential side effects of Synthroid.

Some people may experience:

  • Nausea

  • Hives or welts

  • Change in appetite or weight loss

  • Trouble sleeping

  • Hot flashes

  • Headache

  • Pounding heartbeats

  • Nervousness

  • Chest pain
  • Trouble breathing or shortness of breath
  • Leg Cramps
  • Tremors
  • Appetite loss
  • Vomiting or diarrhea
  • Changes in menstrual periods

These side effects may occur if you take too much Synthroid. Consult with your doctor regarding a Synthroid dose adjustment if you experience these side effects.

How to take Synthroid

You should take Synthroid on an empty stomach, at least 30 minutes before eating. Most foods and drinks can reduce the absorption of the medication, so it's important to take it every day in the morning. Even if you feel better, you need to take Synthroid every day for the rest of your life to replace the thyroid hormones your body cannot produce on its own.

Synthroid FAQs

  1. How much does Synthroid cost?

    Hypothyroidism is a lifelong condition that can be managed with daily use of Synthroid medication, so finding the lowest Synthroid cost is important. You will find cost effective Synthroid and many other discount medications online at

  2. What is the proper Synthroid dosage?

Synthroid doses depend on people's weight, age, cause of hypothyroidism, hormone levels, other health conditions, and other medications you take. Your doctor will take all of those factors into account to find the right dosage for you, which may change over time.

  3. Is there a generic version of Synthroid?

    There are several generic versions of Synthroid, including Levoxyl. However, with hormonal medications such as Synthroid, it is not as simple as making a decision to buy a generic of Synthroid in place of the brand name Synthroid online at international and Canadian pharmacy site, While the non-active ingredients in the brand name and generic form of Synthroid may be different, the active medicinal ingredient is the same but because this medicine helps to regulate hormones in the body, slight variations between the brand and the generic versions can be enough to affect the balance of the hormones being regulated. Levothyroxine is one of the handful of medications that has a narrow therapeutic index (NTI). NTI drugs are those where small differences in dose or blood concentration may lead to dose and blood concentration dependent, serious therapeutic failures, or adverse drug reactions. Because of this, you should always seek special permission from your doctor before deciding to switch between the brand and generic.

  4. Does Synthroid lead to weight loss?

    Some research shows effective treatment with Synthroid or generic levothyroxine does not lead to clinically significant weight loss in most people. Some people may experience weight loss once their thyroid disease is managed.
