Hello,
For prostate problems, antihistaminics and decongestants should be best avoided. There are some newer antihistamines on the market that do not cause these
side effects on your prostate, including Seldane. This can be taken after prescription.
The best way is to reduce exposure to the allergen. To reduce dust mites in your home, remove drapes, feather pillows, upholstered furniture, non-washable comforters and soft toys. Replace carpets with linoleum or wood.
