Can you take benedryl if you have MG?

Based on my experience, I would say yes. They give it to me IV when I have my IVIG to take care of any reactions.

I can't, but from what I hear most people can. I seem to be extra sensitive to medications

I think you must be careful.
There's big difference in getting it premed if you're getting IvIg, because there's a chance the IvIg prevents a reaction otherwise.
If you take it without IvIg, it may be a whole other thing.
It is anticholinergic.

If it's against allergy, there are probably other antihistamines with less anticholinergic effects.

I been told on here by a few folks it's not-advisable, so I am careful.

(Although I possess 2 doctorates in the medical sciences, and taught residents for 20 years in post-grad education, nothing replaces the experiences and knowledge-base of diagnosed persons such as you-girls and guys, so when someone shares, I always listen!) I take Zyrtec D right now for seasonal breathing problems (along with the Singulair and Flonase).

BUT, I am dual-dx with MS and MG, so every one is different. For example, treating my tardive dyskinesia in my case (we use Valium) is totally not recommended for many-many others. Good luck!!

I take Benedryl over the counter all the time. I have also heard that it isn't the best thing for MG people, but works great for me. I try to limit it to no more than 2 a day, even though you can take ever 4 hrs. In San Antonio, Texas, you got to have what works. So bad here.
