I've been prescribed Sumatriptan 4mg/0.5 Injection for my cluster headaches, and it's been a game-changer. However, the side effects list is pretty scary. I'm wondering if anyone else has had any issues with this medication. What about the long-term effects? What are the lesser-known side effects? The FDA warning list is quite extensive and I have no idea what to expect.
