Benadryl, also known as diphenhydramine, is a commonly used over-the-counter (OTC) medication for treating allergies, insomnia, and other conditions. However, it's crucial to follow the recommended dosage guidelines to avoid potential side effects and ensure safe usage. The maximum dose of Benadryl in 24 hours is a critical consideration for individuals taking this medication.
According to the American Association of Poison Control Centers (AAPCC) and the FDA, the maximum recommended dose of diphenhydramine for adults is 300 mg per day. However, the typical adult dose for allergies is 25-50 mg every 4-6 hours, not exceeding 200 mg in 24 hours. Exceeding these limits can lead to severe side effects, including drowsiness, dizziness, rapid heartbeat, and even seizures or coma in extreme cases.
