verapamil ramelteon

Applies to: Isoptin (verapamil) and Rozerem (ramelteon)

Verapamil may increase the blood levels of ramelteon in some patients. This can increase the risk of side effects including daytime drowsiness, motor impairment, amnesia, anxiety, abnormal thinking, hallucinations, behavioral changes, and breathing difficulties (especially if you have a respiratory disorder such as asthma or obstructive sleep apnea). 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. Avoid driving or operating hazardous machinery until you know how these medications affect you, and do not exceed the dosage or frequency of use of ramelteon prescribed by your doctor. 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.
