Drug Allergy & Allergic Reactions to Medications


Any medication could potentially cause an allergic reaction.  It is important to identify a drug allergy because the symptoms can be very uncomfortable or even life-threatening:

  • Hives or rash
  • Itching
  • Asthma attack
  • Swelling (of the tongue or lips, for example)
  • Loss of consciousness
  • Anaphylaxis

Allergic reactions to drugs or medications usually do not occur the first time a person takes a specific drug. You may have been exposed to the medication or a medication in the same drug class without knowing it.

It is also possible that what you think may be a drug allergy could actually be drug interactions or side effect.  For this reason, it is very important to make sure you tell your NY doctor about all of the medications you have been taking.

Common side effects that are not allergic reactions:

  • Diarrhea
  • Dry mouth
  • Headache
  • Heartburn
  • Racing heart

Because these reactions can be complicated, it is very important for you to seek medical attention quickly.  The allergy and asthma associates at the NY Allergy & Sinus Centers will help figure out what is an allergic reaction, as opposed to a side effect of a medication. Allergic reactions can be very dangerous and a NY allergy doctor can assist you in identifying the symptoms of allergies.
