is a sedating antihistamine. It can be given for allergic conditions including allergic rhinitis(running nose, sneezing
,) , urticaria(rashes in the skin with itching), conjunctivitis
. However it can cause sedation, inability to concentrate, dryness of mouth ,etc. These days there are non sedating antihistamines available which would be a better alternative if u need to take one for a longer period of time.
