Some anti-histamines
Cortciosteriods, and bronchidilators

Anti-fungals (for fungal/yeast infections)

Answer 3

Pain killers etc available over the counter are generally fine. Your main worry is the herbal supplements. For example, St John's Wort (used for depression and anxiety) is known to interact with the pill. Rule of thumb: ask the pharmacist. Even if they don't know, they will know where to find reliable information to find out!

Answer 4

none. the only thing you have to worry about are antibiotics.
