Benadryl (diphenhydramine) is an antihistamine commonly used to relieve allergy symptoms, but it also has sedative effects. Taking higher doses of Benadryl than recommended can lead to various side effects, including hallucinations and other cognitive impairments.
The dose of 200 mg is much higher than the recommended therapeutic dose for adults. Typically, the recommended dose for adults is 25 to 50 mg every 4 to 6 hours, not to exceed 300 mg per day. Taking 200 mg at once is significantly higher than what is typically prescribed or considered safe.
Hallucinations and other adverse effects are more likely to occur at high doses, and they can be unpredictable and potentially dangerous. Individual responses to medications can vary, and some people may be more sensitive to the effects of Benadryl than others.
It's crucial to follow the dosing instructions provided by a healthcare professional or on the medication label. If you are experiencing allergy symptoms or other conditions that require antihistamine treatment, it's best to consult with a healthcare professional to determine the appropriate dose for your specific situation.
If you or someone else has taken a high dose of Benadryl and is experiencing concerning symptoms such as hallucinations, confusion, rapid heartbeat, difficulty breathing, or any other severe reactions, seek immediate medical attention or contact a poison control center.
