  • in patients with existing or previous stomach and/or duodenal ulcer, severe ulcerative colitis;
  • in patients who have had allergic symptoms (such as runny nose, angioedema, difficulty breathing (asthma)) after taking acetylsalicylic acid or any other nonsteroidal anti-inflammatory drug;

Infections
Nonsteroidal anti-inflammatory drugs (NSAIDs) may mask the symptoms of infection, such as fever and pain. This may delay appropriate treatment of infections, which can lead to increased risk of complications. If the patient is taking this medicine during an ongoing infection and their symptoms persist or worsen, they should consult their doctor or pharmacist immediately.
During treatment with Strepsils Intensive:

  • At the first signs of any hypersensitivity reaction (rash, desquamation, blisters) or other allergic reaction symptoms, the patient should stop taking the medicine and consult their doctor.
  • The patient should report any unusual abdominal symptoms (especially bleeding) to their doctor.
  • If there is no improvement or new symptoms appear, the patient should consult their doctor.
  • Medicines like flurbiprofen may be associated with a small increased risk of heart attack (myocardial infarction) or stroke. The risk is more likely with high doses and long-term treatment. The patient should not exceed the recommended dose or duration of treatment (see section 3).

Children and adolescents

The medicine should not be taken by children and adolescents under 12 years of age.
