What is Synthroid?

It has never been simpler to order prescription medications online from Canadian pharmacies. True Canada Pharmacy lets you buy Synthroid for a fraction of the cost you are used to paying in the US. Order online today or call us 7 days a week to make big savings.

What is Synthroid?

Synthroid is a thyroid medication containing levothyroxine. Synthroid replaces natural hormones in your thyroid gland in order to regulate your body’s energy and metabolism. Synthroid may also be prescribed to treat hypothyroidism and goitre. Levothyroxine is prescribed when your thyroid does not produce enough of the natural hormone by itself. Having enough thyroid hormone is important for normal physical and mental development.

Always read the medication information and instructions before using this medication.
Always follow your doctor’s directions.

  • Synthroid is typically taken once a day.
  • Synthroid should be taken on an empty stomach between 30 minutes and an hour prior to breakfast.
  • Swallow Synthroid whole with a full glass of water. Do not chew or crush capsules.
  • If you struggle to swallow this medication whole, it can be crushed and mixed into one or two teaspoons of water and taken immediately.
  • It may be several weeks before you notice an improvement in your symptoms.
  • Speak to your doctor if your condition does not improve.


Make sure to tell your doctor:

  • If you have any drug or other allergies.
  • If you take any other prescription or over-the-counter medications.
  • Your medical history especially of bleeding problems, diabetes, adrenal insufficiency, hardening of the arteries, pituitary gland disorders, osteoporosis, heart disease, kidney disease, liver disease or any condition which makes swallowing difficult.
