yes itching can be the first sign of an allergic reaction. to an antibiotic or perhaps something else you have eaten touched or inhaled. even if you have been on this antibiotic before without problems a person can develop adverse reactions including allergic reactions. you need to contact your medical provider immediately for patient-specific advice which may include stopping (and changing) the antibiotic you are taken and prescribing something like an antihistamine to counteract a possible allergic response. antihistamines assuming you can take this sort of drug are used to stop the itching.
is itching a side affect of anit-biotics? . i have been on and off anti-biotics since the first of sept. for pneumonia and bronchitis. i am now and have for about 3 wks itching all over. is this possibly a side effect of the meds?
