I'm scheduled for some intense chemotherapy and my doctor prescribed Granisetron to help with nausea and vomiting. I've read about the side effects and they seem scary - especially that serotonin syndrome. Has anyone had experience with this? Any tips for dealing with the side effects, or should I be worried? I know everyone's different but any anecdotes would be appreciated.

Granisetron worked great for me during chemo. I didn't experience any major side effects, just a bit of dizziness. But everyone's different, so stay in touch with your doctor.

I had a bad reaction to Granisetron. Felt like I was having a heart attack. Doc switched me to something else. If you feel chest pain, go to the ER ASAP!

Why do they always give us the scary side effects, we know it's rare, but I was freaked out for nothing

I'm on my 3rd cycle and it's been okay. Some dizziness, but nothing I can't handle. Fingers crossed for you!

Be aware of what you eat - eating small meals and avoiding fatty stuff can help a lot. Also, stay hydrated! Good luck!

Did your doctor mention if there's a generic version? It's always good to save a bit of money if you can.

I had the worst headache and constipation, but it could have been worse. Docs told me how to manage it.

I had no idea this stuff could cause serotonin syndrome. Good to know – thanks for posting!

Serotonin syndrome is rare, but it's good you're aware. Just don't mix it with other stuff that affects serotonin levels. Stay safe!

I wouldn't worry too much. The side effects sound scary, but they're pretty rare. Just keep an eye out and talk to your doctor if something feels off.
