Non sedating antihistamines side effects Adult dating free local site
You can safely use antihistamines for other conditions when you have asthma.Older antihistamines are called classical antihistamines. They are effective but have more side effects and a shorter duration of action than the newer non-sedating antihistamines. These drugs include chlorpheniramine maleate (Chlor-TrimetonÂ®), brompheniramine maleate (Childrenâï¿½ï¿½s DimetappÂ®), diphenhydramine (BenadrylÂ®), and clemastine (TavistÂ®).AtaraxÂ® (hydroxyzine) is particularly effective at suppressing itching.Meclizine (BonineÂ®) is superior to other antihistamines for dizziness. The major disadvantage of classical antihistamines is their tendency to cause central nervous system depression, drowsiness, and sedation.
However even though you no longer feel sleepy your reaction time may not improve.The first antihistamines were developed during World War II.These drugs have been around for as long as penicillin and fifteen years longer than TylenolÂ®.Antihistamines work better when theyâï¿½ï¿½re already in place when mast cells release histamine.Since mast cells release many other active chemicals, antihistamines cannot completely block an allergic reaction; they simply diminish it.
It's a good idea to avoid other drugs that may make you drowsy or effect your judgment or timing when you're taking a classical antihistamine.
