All About Drug Allergy
To generate antibodies to fight the drug. Most of these adverse reactions appear as skin rashes or irritations, hives or swelling, mostly in the face or hands. Adverse drug reactions, or ADRs as they are called in medical parlance, usually happen when there is an overdose or indiscriminate self-medication. Sometimes, it happens when the patient is taking multiple drugs, wherein one drug reacts with another adversely.
Dr. Jerry Schier, board-certified allergist of the George Washington School of Medicine says that true allergies are rare, although most people experience adverse reactions to drugs at some point in their lives. Though most of these adverse drug reactions can be quite harmless, some of them can be life threatening like anaphylactic shock or loss of consciousness.
Common Symptoms of Drug AllergiesSome of the usual symptoms of the adverse reactions to drugs can be:
Rashes Hives Swelling in the hands and face and fever Constipation or diarrhea, along with gastric problemsSevere reactions in some rare cases can include loss of consciousness, anaphylaxis, stomach cramps, or breathing difficulties, usually due to a swollen larynx. Coughing, wheezing and a runny nose can also be contraindications of some drugs. Most drug reactions are not allergic reactions and so do not involve the immune system. Some of the most severe adverse drug reactions can be skin blisters which peel, and lead to toxic epidermal necrolysis, which can be fatal if left untreated.
Allergy Causing DrugsMost drug-induced allergies are caused by drugs like antibiotics and similar preparations. Some of the drugs that could induce allergies are:
Penicillins like ampicillin, amoxicillin, and nafcillin can be allergic to many people, leading to paralytic attacks and fatalities if not treated immediately. Aspirin, ibuprofen, and other such non-steroidal anti-inflammatory drugs (NSAIDs). and barbiturates. Vaccines. Anticonvulsants. Drugs that treat hyperthyroidism.Allergy to one generic drug might be an indication of allergy to other similar drugs. People with AIDS or lupus can be quite allergic to many drugs. Though the allergic reactions may not be severe, they can make treating the ailment very tricky and difficult.
Another group of people who are prone to having adverse reactions to drugs are those suffering from asthma. They can have adverse reactions to even common medicines like aspirin or ibuprofen, though not very severe ones.
