Urology/BPH and antihistamines

Question
I am a retired 65 year old American male living in Malaysia. I have BPH and chronic sinusitis. Every healthcare professional I have seen says to avoid antihistamines if I have BPH, but no one can tell me what antihistamine is safe to take. Can you tell me if there is an antihistamine that I can take to alleviate my sinus problems and still be able to urinate? Thank you for your time.

Answer
Steve:

First, chronic sinusitis can be treated with inhaled steroids and antibiotics.  Most first generation antihistamines (benadryl) have some anti-cholinergic (bladder relaxing) effects which can cause problems with urination.  Second generation antihistamines are usually considered safe.  Such medications include zyrtec, claritin and allegra.  Avoid decongestants as they will all have a worsening effect on the prostate.
