I've been taking PrEP for about 2 weeks now. I don't have any side effect from it anymore but yesterday I started off with a sore throat and nasal passage and today I woke up with a headache, a stuffy but runny nose although my throat feels a bit better. I can't remember what my doctor that gave me PrEP said I think she said avoid Advil and take Tylenol but I don't have either so U was wondering if the acetaminophen, phenylephrine HCI, and dextromethorphan HBr would negatuvely react with the PrEP. I took my last dose at 12-1am today and it's now 2:24pm on the same day so maybe there's enough time in between to not have effects if any?
