can benadryl help with alcohol withdrawal

By A to Z Alcohol Editorial TeamPublished Apr 24, 2026Updated Nov 4, 20261 min read
Quick answer

We found no official source that recommends Benadryl (diphenhydramine) for alcohol withdrawal, and it is not a substitute for medical care. MedlinePlus says moderate-to-severe withdrawal may need hospital care with monitoring and sedatives. NIAAA also lists drowsiness, dizziness and higher overdose risk when Benadryl is mixed with alcohol.

What the official pages say

MedlinePlus says withdrawal symptoms usually begin within 8 hours of the last drink and tend to peak at 24 to 72 hours. Symptoms include anxiety, tremor, sleep problems, sweating, nausea and fast heart rate. Treatment for moderate or severe cases can include monitoring, IV fluids or medicines, and sedatives.

Benadryl

We found no MedlinePlus or NIAAA statement that diphenhydramine treats alcohol withdrawal. NIAAA’s medicine-interaction list shows Benadryl with alcohol can cause drowsiness, dizziness and increased risk for overdose.

Get help right away if

  • You have seizures, fever, severe confusion or hallucinations.
  • You have an irregular heartbeat.

MedlinePlus says to go to the emergency room or call 911 for these signs. Withdrawal can be fatal, especially delirium tremens.

Do not stop alone

If you drink heavily every day, talk to a doctor or pharmacist before cutting back. Mild-to-moderate cases may be managed at home only with provider visits and someone staying with you.
