dihydroergotamine phenylephrine

Applies to: dihydroergotamine and Ricobid-D (phenylephrine)

Using dihydroergotamine together with phenylephrine is generally not recommended. Dihydroergotamine may cause significant increases in blood pressure by constricting the blood vessels, and the risk for complications may be increased when used with other drugs that also have this effect such as decongestants, stimulants, and certain medications for headache, glaucoma, or eye redness relief. Combining these medications may also reduce blood flow to vital organs and increase the risk of rare but serious side effects such as heart attack, stroke, intestinal problems, and gangrene (death of tissues, usually in the arm or leg, that may require surgical amputation). 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 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, severe or throbbing headache, irregular heartbeat, shortness of breath, blurred vision, confusion, and/or slurred speech 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.
