Generic Name: Cyprogin hydrochloride Dosage Form: tablet
Medically reviewed by Drugs.com. Last updated on Jun 1, 2019.
Reproduction studies have been performed in rabbits, mice, and rats at oral or subcutaneous doses up to 32 times the maximum recommended human oral dose and have revealed no evidence of impaired fertility or harm to the fetus due to Cyprogin. Cyprogin has been shown to be fetotoxic in rats when given by intraperitoneal injection in doses four times the maximum recommended human oral dose. Two studies in pregnant women, however, have not shown that Cyprogin increases the risk of abnormalities when administered during the first, second and third trimesters of pregnancy. No teratogenic effects were observed in any of the newborns. Nevertheless, because the studies in humans cannot rule out the possibility of harm, Cyprogin should be used during pregnancy only if clearly needed.

Why is this medication prescribed?
Cyprogin relieves red, irritated, itchy, watery eyes; sneezing; and runny nose caused by allergies, irritants in the air, and hay fever. It may also be used to relieve the itching of allergic skin conditions, and to treat hives, including hives caused by exposure to cold temperatures and by rubbing the skin. Cyprogin is also sometimes used to treat allergic reactions in people who have received blood products as part of medical treatment and to treat life-threatening allergic reactions after the symptoms have been brought under control with other medications. Cyprogin will help relieve symptoms but will not treat the cause of symptoms or speed recovery. Cyprogin is in a class of medications called antihistamines. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms.
