What Is an Allergic Reaction?

An allergic reaction occurs when the immune system overreacts to a medication. Symptoms may range from mild skin irritation to severe anaphylaxis.

Allergic reactions are different from typical mild side effects such as dizziness or nausea.

Mild Allergic Symptoms

  • Skin rash
  • Hives
  • Itching
  • Mild swelling

These symptoms may appear shortly after taking the medication.

Moderate Hypersensitivity Symptoms

  • Facial swelling
  • Lip or tongue swelling
  • Persistent itching
  • Widespread rash

Medical evaluation is recommended if moderate symptoms occur.

Severe Allergic Reaction (Anaphylaxis)

Rare but serious symptoms include:

  • Difficulty breathing
  • Throat tightening
  • Severe dizziness
  • Drop in blood pressure
  • Loss of consciousness

Call emergency services immediately if these occur.

Distinguishing Allergy from Parasite Die-Off Reaction

In some infections, inflammatory reactions may occur due to parasite die-off. These reactions may mimic allergic symptoms but are not true allergies.

Physician evaluation helps determine the cause.

  • Immune disorders
  • Multiple medication sensitivities

Patients with prior drug allergies should inform their healthcare provider before starting ivermectin.
