Brief Answer:
Drug Induced Urticaria
Detailed Answer:
Hi.
Thanks for your Query on XXXXXXX
Penicillin group of drugs (
Amoxycillin) are one of the common causes of Drug induced Urticaria (Hives).
Drug induced Urticaria is allergic in nature: Means your body already has
antibodies against the drug. So whenever you take this drug, antibodies which are already present in your blood would bind to the Antigen (Drug), thus giving rise to drug reaction(Urticaria).
I would advice that you stop taking this drug.
Apply a cooling and soothing lotion. Various soothing and anti-pruritic agents like calamine +
zinc oxide, menthol, camphor, pramoxine hydrochloride(topical antihistamine) are available in lotion form OTC.
Intake of an oral antihistamine for 7-10 days like
Cetrizine once OR twice daily (Morning and Evening) is also advisable
If your rash is very troublesome and itchy, then you should visit the nearest emergency department, the doctor on duty might decide to administer I/V injection of a short acting steroid Like
hydrocortisone acetate 100mg for rapid relief.
Send me a picture of the rashes, if possible. If you need any further help let me know
Take care
