What should you know about Benadryl for jet lag?

Jet lag happens when your internal sleep-wake rhythm is out of step with local time after travel across time zones. Benadryl is an antihistamine; its sedating effect can make you feel sleepy, while next-day grogginess, dry mouth, blurred vision, or impaired coordination can affect travel and work. It does not provide the timed light and sleep cues that help the body adjust.

Shift sleep gradually before departure when practical, use local daylight to support the new schedule, and keep meals and activity aligned with local time. Drink water and avoid driving or alcohol if you feel drowsy. Keep your first days flexible. Persistent Difficulty Sleeping or Daytime Sleepiness may need a clinician’s assessment; Insomnia Management can offer structured non-drug measures.

Get urgent help for fainting, severe confusion, breathing difficulty, or an allergic reaction after taking Benadryl. Seek medical advice if sleepiness interferes with driving, you have repeated falls, or sleep problems continue after your travel schedule has settled. Ask before use if you have glaucoma, urinary difficulty, breathing disease, pregnancy, or take sedating medicines.

Could my symptoms be Jet Lag or another sleep disorder? Which plan fits my destination, medicines, and health conditions? How long should I avoid driving after a sedating medicine?
