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!!
