Is it safe to take acuvail while pregnant or breastfeeding?

Acuvail. Pregnancy class c but also depends on trimester and population specific. Ask your ob/gyn about this one.
Yes. Probably as this is in the class of NSAID medications like Motrin (ibuprofen) which have been used for severe arthritis. As eye drops the negligible amount that might enter your body should not be of concern.
