What over-the-counter medications should i avoid. i have sinus and allergy problems and sometimes take what i have on hand is that ok?

Caution with some: Oral decongestants like Pseudoephedrine may help, but can lead to appetite suppression, dry mouth, more difficult to control high blood pressure and trouble urinating. Nasal decongestant spray like afrin also can help but if used more than 4-5 days may lead to rebound severe nasal congestion.

Sinus problems: With your historic would be very careful with medications. I would. Avoid decongestants and would try to use nonsedating antihistamines but really i would call your doctor and ask him for a nasal steroid, they are the easiest and the safest they are not systemically absorbed stay away from liver metabolized drugs if you have ascities. Good luck !
