Benadryl Side Effects Center

Benadryl (diphenhydramine) is an antihistamine used for allergies, hives, insomnia, motion sickness, and mild cases of Parkinsonism. A generic formulation is available. Common side effects of Benadryl include sedation, tiredness, sleepiness, dizziness, disturbed coordination, drying and thickening of oral and other respiratory secretions, and stomach distress. Benadryl may also cause blurred vision, double vision, tremor, loss of appetite, or nausea.

A typical dose of Benadryl is 25-50 mg every 4-6 hours. Benadryl adds to the sedating effects of alcohol and other sedating drugs. It can also intensify the drying effects of medications with anticholinergic properties. Benadryl has not been adequately evaluated in pregnant women. Benadryl is secreted in breast milk. Because of the risk of stimulation and seizures in infants, especially newborns and premature infants, antihistamines should not be used by nursing mothers.
