Benign Prostatic Hyperplasia
What are the drug classes that men with BPH should not take?
If possible, men with BPH should avoid taking drugs that contain antihistamines and decongestants (e.g., sprays to relieve cold or rhinitis symptoms and anti-allergy medications). These drugs appear to interfere with prostate relaxation mechanisms, aggravating the symptoms associated with prostate enlargement. In any case, consult your physician to find alternative treatments for allergies and colds.
