These were the only 2 antihistamines that were really effective for me personally.
Prolaramine is not available however there appears to be some manufactures of the same med (but it is a higher strength) the drug name is Dexchlorpheniramine.
Seldane was removed from the market in 1998 due to very severe side effects of QT-prolongation that could causes deadly heart arrythmias. The alternative is Allegra (fexofenadine). When you took Seldane the body converted it to two chemicals a good one that gave you benefite and a bad one that caused the side effect. They now make a drug that just has the good benefits with out the deadly side effects. It is allegra (fexofenadine).
