Missed dose and overdose

If you miss a dose

Take it as soon as you remember. If your next dose is almost due, skip the one you missed — never take two doses together to catch up.

Warnings and precautions

Take it on an empty stomach, first thing in the morning, with water, and wait at least half an hour to an hour before eating or drinking anything else. Food, tea and coffee substantially reduce how much is absorbed. Separate it by at least four hours from calcium, iron, antacids and multivitamins — these bind it and block absorption. This is usually lifelong treatment. Do not stop when your reports come back normal; the normal report is the medicine working. Report palpitations, tremor, marked weight loss or difficulty sleeping — these suggest the dose is too high. Tell your doctor if you become pregnant; the requirement usually rises and needs prompt adjustment.

Do not take Thyrofit if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Not for people with an untreated overactive thyroid or untreated adrenal insufficiency.

Interactions with other medicines

Calcium, iron, antacids, multivitamins and some cholesterol medicines block absorption — separate them by four hours. Tell your doctor if you take a blood thinner or diabetes medicine; doses may need review.

How to store Thyrofit 125

Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
