Interactions between your drugs
itraconazole methysergide maleate
Applies to: Tolsura (itraconazole) and methysergide maleate
Using methysergide maleate together with itraconazole is not recommended. Combining these medications may significantly increase the blood levels and effects of methysergide maleate, which in some cases can lead to 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). Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact. 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 methysergide maleate. Do not take larger doses or use the medication 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.
