Drug Interaction Report

Taking liothyronine and didanosine too close together may interfere with the absorption of liothyronine and reduce its effectiveness. To prevent or minimize potential interaction, these medications should preferably be taken at least four hours apart. Contact your doctor if you experience signs and symptoms of reduced thyroid function such as fatigue; sluggishness; constipation; depression; hoarseness; unexplained weight gain; sensitivity to cold; pale, dry skin; muscle ache, weakness, or tenderness; joint pain, stiffness, or swelling; heavier than normal menstruation periods; or brittle fingernails and hair. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Food decreases the levels of didanosine in your body. Take didanosine on an empty stomach at least 30 minutes before or 2 hours after a meal. This will make it easier for your body to absorb the medication. Do not crush, chew, break, or open a delayed-release capsule (Videx EC). Swallow the pill whole. It is specially made to release medicine slowly in the body. Breaking or opening the pill would cause too much of the drug to be released at one time.

Using multivitamin with minerals together with liothyronine may decrease the effects of liothyronine. You should separate the administration of liothyronine and multivitamin with minerals by at least 4 hours. If your doctor does prescribe these medications together, you may need a dose adjustment or special test to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
