Adverse reactions to medications which are considered by
some experts to be allergic are un- toward effects on blood platelets leading
to hemorrhages into the skin, depression of blood cell production in bone
marrow, and liver reactions. The list includes it agents as aspirin, sulfa
com- I'0unds, tetracycline and other antihrotlrs, insulin, antitoxins, local
anestheues such as procaine, some of the Iranquilizers, mercury, and arsenic.
In one case, a person seemingly allergic to a medicine may actually be acting
to milk sugar used as a filler for the tablet or a dye used to color I pill. An
important preventive measure for anyone with sensitivity to a medicine is to
carry a card or bracelet indicating so, and also to announce the fact to every
doctor or nurse who has occasion to take care of him.
And when such a person is
in a hospital, there should be a sign on or near his bed or in the room stating
sensitivity to a given medicine. A person experiencing a severe allergic or
other adverse reaction to a medicine should be promptly treated hy a doctor or
go to an emergency loom in a hospital. It is not enough to rely on an
antihistamine, which may be useful for a mild reaction.
Skin Allergy HIVES. A hive is a raised, blister- like area
containing fluid, white in color but surrounded by a reddened area. It usually
itches intensely. An acute attack of hives-also known as urticaria, giant
hives, angioedema, angioneurotic edema, and nettle rash-may be caused by
allergenic foods, medicines, or serums.
There are also physical causes such as
sunlight, heat, cold, and pressure on the skin. When hives are accompanied by
edema or water-logging and swelling of throat and laryngeal tissues, there may
be danger to life. Treatment is effective. In addition to the same medicines
used for hay fever, the doctor may prescribe soothing creams, lotions, or baths
for the itching skin.
Sometimes a strong laxative helps shorten an attack induced
by food by hastening its elimination from the intestine. People subject to
recurrent severe hives should be prepared to act to prevent an attack from
progressing to the point of interfering with breathing. They should learn from
their doctors how to handle an emergency and should carry the necessary
materials with them at all times. There seems to be a strong emotional
component in some cases of recurrent hives. Patient and doctor should discuss
life-style and tensions and consider whether a session with a psychotherapist
might be helpful.
