Side effects: These are not common side effects of penicillin but if you experience them every time you're on penicillin, it apparently affects you that way. Some patients are more intolerant of any medication than other patients.

Not penicillin: I suggest you call your physician and temporarily stop the penicillin; however, this is NOT a normal side effect of penicillin; however, your symptoms deserve further medical evaluation.

Not Usually: Penicillin is not usually associated with the symptoms you describe but any medication can produce various symptoms in any given person, as could the underlying condition for which you are taking the penicillin. If your symptoms worsen or persist, allergic reaction or interaction with other medications you may be taking should also be considered.
