Oral drops: Drowsiness is a major problem with antihistamine and those affected should not drive or operate machinery. Reduced dosage is recommended for patients with renal impairment and is contraindicated for patients with cardiac disease. Antihistamine should not be given to neonates owing to their increased susceptibility to antimuscarinic effects. It has also been recommended that antihistamines should be avoided in young children. Elderly patients are also more susceptible to many of the adverse effects of antihistamines and in particular, their inappropriate use for postural giddiness should be avoided.
