Always follow your doctor’s instructions. For adults, the usual dose is 25-50 mg every 4-6 hours as needed for sleep or allergy relief, not to exceed 300 mg in 24 hours. Children’s dosages vary significantly by age and weight; consult a pediatrician for appropriate guidance.
Take the capsules whole with a full glass of water. Avoid crushing or chewing the capsules as this can alter the absorption rate and potentially cause stomach upset.
Important Considerations: Do not operate machinery or drive after taking diphenhydramine, as drowsiness is a common side effect. Avoid alcohol consumption while using this medication. Diphenhydramine can interact with other medications; inform your doctor or pharmacist about all medications, including over-the-counter drugs and herbal supplements, you are currently taking.
Seek immediate medical attention if you experience severe allergic reactions like hives, difficulty breathing, or swelling of the face, lips, or tongue.
