Because the new COVID vaccine is out and someone asked me for a reminder: it's 50mg diphenhydramine 15m before the shot or 20mg cetirizine 2-3 hours before (if you have MCAS add an extra 20mg famotidine + 10mg montelukast (if taking) when you take the others) to avoid feeling like death

Giving this a shot, as it were. 🤞🤞

Thank you. I didn't know this. I haven't been diagnosed with MCAS but vaccine other than novavax makes my fibro flare. I'll try cetirizine prior next time as I do have some
