Cyproheptadine

Cyproheptadine is an antihistamine and anticholinergic medication. It is primarily used to treat allergic conditions such as hay fever, urticaria (hives), and angioedema. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms. Cyproheptadine also has antiserotonergic effects, which contribute to its appetite-stimulating properties. This effect has led to its use in some cases to increase appetite, particularly in individuals experiencing anorexia or weight loss.

The drug is available in various forms, including tablets, syrup, and oral solutions. Common side effects can include drowsiness, dizziness, dry mouth, blurred vision, and constipation due to its anticholinergic activity. It is important to note that cyproheptadine can impair cognitive and motor skills, so caution is advised when operating machinery or driving. It is generally not recommended for use in infants and young children due to the potential for central nervous system excitation.

Cyproheptadine is a prescription medication in many regions, and its use should be guided by a healthcare professional. Dosage and duration of treatment depend on the specific condition being treated and the patient's individual response. It is contraindicated in individuals with narrow-angle glaucoma, prostatic hypertrophy, and urinary retention.
