Which medicines should not be taken when the allergy is active?

When your allergy is active, propranolol heart palpitation pill which strongly causes asthma and captopril and enalapril blood pressure pill which causes cough will be problematic for allergy sufferers.

Also, the use of painkillers and especially gelofen is not recommended for patients with nasal and sinus allergies, because polyps may develop with the use of this medicine. 

Nothing other than plain acetaminophen is recommended.

Contraceptives are also allergenic in some cases
