WARNING

Dihydroergotamine injection, commonly used to treat migraines, carries several risks that users should be aware of:

• Cardiovascular Effects: Dihydroergotamine can cause vasoconstriction, which may lead to cardiovascular issues such as increased blood pressure, chest pain, and in rare cases, heart attack or stroke.
• Peripheral Ischemia: This medication can reduce blood flow to extremities, leading to symptoms like cold hands or feet, numbness, and tingling.
• Drug Interactions: Dihydroergotamine can interact with various medications, including certain antidepressants, antifungals, and HIV protease inhibitors, potentially leading to serious complications.
• Serotonin Syndrome: Combining dihydroergotamine with certain serotonergic medications (e.g., SSRIs, SNRIs) can increase the risk of serotonin syndrome, a potentially life-threatening condition characterized by agitation, confusion, rapid heart rate, and high blood pressure.
• Allergic Reactions: Some individuals may experience allergic reactions to dihydroergotamine, presenting symptoms like rash, itching, swelling, or difficulty breathing.
• Other Side Effects: Additional side effects may include nausea, vomiting, dizziness, and muscle pain.

It’s crucial to use dihydroergotamine under medical supervision and to discuss any concerns or pre-existing conditions with a healthcare provider before starting this medication.
