Interactions between your drugs

Major

clarithromycin loperamide

Applies to: amoxicillin / clarithromycin / lansoprazole and loperamide

Clarithromycin may significantly increase the blood levels of loperamide. This can lead to serious and potentially fatal complications such as irregular heart rhythm and cardiac arrest, especially if you use more than the recommended doses of loperamide. You may also be more susceptible if you have a heart condition called congenital long QT syndrome, other cardiac diseases, conduction abnormalities, or electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting). Do not exceed the dose and frequency or duration of use of loperamide recommended on the product label or prescribed by your doctor. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with these 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.
