The drug or any of its ingredients or products sensitizes
its user by combining with the protein in the body for
producing the antigen which leads to creating the
antibodies. Repeated exposure to the drug instigates the
antigen-antibody reaction which may manifest itself as
anything from milder skin reaction to the life threatening
reaction like anaphylaxis.
Symptoms: Most of the alergic reactions occur within one
hour of ingestion of the medications and involve some of the
common allergic symptoms that include: hives – itchy,
slightly red and swollen patches on the skin surface; skin
rashes; itching on the lips – tongue and / or face;
sensitivity of the skin to the sunlight – itchy and scaly
rashes when skin is exposed to the sun. However, within 1 or
2 weeks of taking the medications some of the additional
symptoms may also be experienced such as: fever; muscle and
joint aches; swollen throat glands – lymph nodes; and
changes in urine color. Also low blood pressure, wheezing
and other symptoms or signs may signal the probable life
threatening reactions which are known as anaphylaxis. Some
of the alergic reactions may occur without any earlier
symptoms of the allergy.
Causes: The allergic reaction occurs when the body’s immune
system produces antibodies and triggers the disease-fighting
cells in response to the offending drug.
Painkillers and antibiotics: Painkillers like aspirin or NSAIDs or antibiotics mainly cause alergic reactions.
Treatments: Most of the drug allergies are found to be well
responding to the medications. Proper treatment in
combination with preventing the probable allergen or default
medicine may help people recover from the allergic reactions
within 2 to 3 days.
Risk: Frequent exposure to drugs, larger doses of the drug
whether pill or injection may cause serious risk to the drug alergic people.
