Few of us realise that we could be allergic to our medicine, whether prescription or over-the-counter. The reaction can be mild, moderate or severe.
The allergic reaction can come on in a matter of minutes, or take days or even weeks, to develop. People are mostly allergic to anti-inflammatory painkillers and antibiotics, such as penicillin.
Allergic reactions to medication often show up in the skin in the form of acne spots, small boils, blisters, red lumps, rashes, purple spots or bumps, itchy, raised wheals and inflamed blood vessels. Severe reactions include anaphylaxis and a life-threatening condition known as Stevens-Johnson syndrome.
Stopping the medication usually resolves the problem, although some skin reactions could take up to two weeks to fade.
If you have a drug allergy, be sure to carry a medical emergency ID bracelet with the relevant information at all times.
