Sorry this will be a late reply pero sana makatulog pa rin kahit for future referrence:
Safe naman uminom ng Neozep while taking Amoxicillin (Amoxil) at Mefenamic Acid, kung ito lng nman ang mga gamot na iniinom mo at wala ka history ng allergy sa alinman sa mga nabanggit.
Neozep comes in two reformulated variants, forte and no-drowse. Ung forte contains Phenylephrine (nasal decongestant), Chlorphenamine maleate (antihistamine/anti-allergy) and Paracetamol (pain reliever/anti-fever), while the no-drowse has no antihistamine. Reformulated kasi pinalitan ng phenylephrine yung phenylpropanolamine na in many clinical studies proved na risky ibigay sa mga may hypertension at sakit sa puso.
So as per side effects, yung may antihistamine nkakaantok, yung may decongestant, kagaya ng phenylephrine, pwedeng magbigay ng dry sensation sa mouth and throat. Bothersome side effects kung titingnan pero in a way help you get better lalo na from flu or trangkaso. Mas mkakapagpahinga ka dahil patutulugin ka nung antihistamine, and mapaparami ka ng inom ng tubig dahil sa effect ng decongestant.
Hope that answers the question (kahit late na) and sana makatulong sa iba.
If symptoms persist (please) consult your doctor (or any health care practitioner).
