There are an estimated 20 million Americans with some form of thyroid disease. The specifics of the thyroid problems may vary from person to person, but Synthroid is one of the best ways to treat many thyroid disorders.

So if you have thyroid problems, you should know about Synthroid. In this post, we’ll guide you through everything you need to know about the drug.

What is Synthroid?

Synthroid is the brand name for a drug called levothyroxine. As the brand name may suggest, the drug is used to replace or provide extra hormones to correct under-active thyroid glands.

The drug is also used in conjunction with other treatments for thyroid cancer, goiters, and several other thyroid issues.

How to Use Levothyroxine

Levothyroxine is typically issued in the form of a pill. Your prescribing doctor will be able to give you specific instructions, but generally, you take the pill once daily on an empty stomach first thing in the morning. Then, you’re supposed to wait 30 minutes to an hour to eat breakfast after taking the pill.

If you’re taking this drug in capsule form, be sure not to break, split, crush, or chew the pill. This drug is meant to digest slowly, so you should always swallow it whole.

However, if the drug is being prescribed to a child or infant that cannot yet swallow whole pills, crush the capsule and mix it into 5-10 milliliters of water.

Side Effects

The biggest and most dispiriting side effect of Synthroid is hair loss. This typically happens in the first few months of treatment, but luckily it is only temporary. Because the drug drastically changes your body’s hormone production, your hair growth is interrupted, but your body will eventually balance out.

Aside from that, other side effects you may experience are increased sweating, mood swings (again, from hormonal changes), sensitivity to heat, fatigue, shaking/tremors, and diarrhea.

If you experience any of the following side effects, you should alert your doctor immediately, as they may be signs of a serious allergic reaction:

  • rash
  • itching
  • swelling of the ankles
  • severe dizziness
  • trouble breathing


As always, you should tell your doctor what medications you are already taking when being prescribed a new medication. This is especially important when being prescribed levothyroxine, as certain medications can prohibit the absorption of the thyroid hormone created by the drug.

Even common medications like antacids, calcium or iron supplements, limit the effectiveness of the drug. If you do have to take these medications, make sure to separate them and levothyroxine by at least 4 hours.
