ITCHING

When itching is generalized and accompanied by a rash, it may be due to an allergy reaction produced by a drug, foodstuff or cosmetic. If the itching is generalized and accompanied by a yellowish coloration of the skin, jaundice is a possible explanation and medical help should be sought as soon as possible. Localized itching can be caused by insect bites and stings, worms, or piles, thrush, eczema (there will usually be a noticeable skin rash). Often however, itching is caused by factors which cannot easily be diagnosed. In the elderly, for example, inexplicable itching is relatively common. Whatever the cause, the best first aid remedy is to soothe the area with calamine lotion or with a cold cloth. Professional advice should be sought as soon as possible so that a precise diagnosis can be made.

DRUG REACTIONS

Skin rashes of many different kinds can be caused by both prescribed drugs and drugs that have been bought over the counter without a prescription. The majority of reactions seem to be pink or red, spotty and itchy. It is often difficult to confirm the relationships between a skin problem and a specific drug but if you experience such a problem after starting a new drug you should report the fact to your doctor. Remember that drug reactions may take a week or two to develop, so the symptoms may also arise after the drug has been stopped. Drug reactions usually fade when you stop taking the drugs responsible.
