Levothyroxine works best if you take it on an empty stomach, at least 30 minutes before breakfast.
Follow your doctor's dosing instructions and try to take the medicine at the same time each day.
It is very important to take Levoxyl with a full glass (8 ounces) of water. The Levoxyl tablet can

While using levothyroxine, you may need frequent medical tests.
Tell any doctor or dentist who treats you that you are using levothyroxine.
Store at room temperature away from moisture and heat.
It may take several weeks before your body starts to respond to levothyroxine. Keep using this
medicine even if you feel well. You may need to use this medicine for the rest of your life to
replace the thyroid hormone your body cannot produce.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your
next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
Overdose symptoms may include headache, leg cramps, tremors, feeling nervous or irritable,
chest pain, shortness of breath, and fast or pounding heartbeats.
What should I avoid?
Certain medicines can make levothyroxine less effective if taken at the same time. If you use any
of the following drugs, avoid taking them within 4 hours before or 4 hours after you take
levothyroxine:
calcium carbonate (Alka-Mints, Calcium Oyster Shell, Caltrate, Os-Cal, Oyster Shell Calcium,
Rolaids Soft Chew, Tums, and others);
cholestyramine, colestipol;
ferrous sulfate iron supplement;
sucralfate;
sodium polystyrene sulfonate (Kalexate, Kayexalate, Kionex); or
antacids that contain aluminum or magnesium - Acid Gone, Gaviscon, Maalox, Milk of
Magnesia, Mintox, Mylanta, Pepcid Complete, and others).
Avoid the following food products, which can make your body absorb less levothyroxine: infant soy
formula, cotton seed meal, walnuts, and high-fiber foods.
