Interactions between your drugs

Major

rizatriptan eletriptan

Applies to: rizatriptan and eletriptan

Using eletriptan together with rizatriptan is not recommended. Combining these medications may have additive effects and cause excessive narrowing of blood vessels in the body. This can reduce blood flow to vital organs and increase the risk of rare but serious side effects such as high blood pressure, heart attack, stroke, and gangrene (death of tissues, usually in the arm or leg, that may require surgical amputation). You should seek immediate medical attention if you experience severe abdominal pain, nausea, vomiting, numbness or tingling, muscle pain or weakness, blue or purple discoloration of fingers or toes, pale or cold skin, chest pain or tightness, irregular heartbeat, severe headache, shortness of breath, blurred vision, confusion, and/or slurred speech during treatment with these medications. Do not take larger doses or use the drug more frequently than prescribed. 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.
