just take whatever they give you for the condition(s) you have… cough syrup for coughs and ibuprofen for the headache/fever. DONT take anything that ends in -cillin or -maycen (they WILL prescribe it, trust me, especially for smaller clinics) because they are antibiotics and cold/flu is a virus and antibiotics does nothing to them and some may be allergic to them which makes things much worse! If you don’t know what is what demand to know. I went to a doctor for a flu and they gave me something like 9 types of drugs but I only took the ones that matters (ibuprofen for the headache) and pretty much threw away the stuff packed together in a bag… there’s no way I am getting that stupid rash like I did 2 summers ago.
Only take the antibiotics if you have an actual bacterial infection (you know, TB and E Coli and etc) otherwise stay away from them. You will know if you need them.
