Defrinol – how to use, dosage and side effects

Defrinol is a drug that contains two active ingredients: ibuprofen in a dose of 200 mg and the pseudoephedrine in a dose of 30 mg. The combination of these two substances is used to relieve the flu and cold symptoms, because ibuprofen reduces inflammation and fever (high temperature), while pseudoephedrine constricts blood vessels in the lining of the nose, which open the airways and make breathing easier. It is used to relieve cold and flu symptoms:

  1. sore throat,
  2. fever,
  3. nasal congestion,
  4. headache and other symptoms.


Defrinol should be avoided in patients allergic to the active substance/s: ibuprofen and pseudoephedrine. Contact your doctor if you are experiencing symptoms of an allergy, such as:

  1. redness,
  2. swelling of the face,
  3. swelling of the tongue,
  4. difficulty breathing.
