my question is this: I thought I had a sinus infection and went to the doctor and was prescribed prednisolone and amox-clav500 substituted for augmentin. I took all of the prednisolone and all of the augmentin except 5 pills. it was giving me diarrhea. I still have a cough and a rattle in my throat. I cough up mucus and blow out mucus all day. is it okay for me to take mucinex expectorant? I am presently taking atenolol for my blood pressure, levothyroxine for thyroid, timolol and travatan for glaucoma, D3 for calcium ,clonazepam for anxiety,vitamins b,c and calcium. thank you
