if your medical provider has prescribed penicillin for a bacterial infection then yes. if you are self-prescribing penicillin for your "cold" then be advised that colds are viruses and penicillin does not work for viruses. when you have high blood pressure certain cold medications should not be taken so please consult your medical provider or pharmacist for advise -- someone who knows the exact medications you are taking or plan on taking. i do not have this information nor do i know your medical history.
id like to know can i take penicillin with allergy/cold medicine. i also take high blood presssure pills.
