Potential Side Effects of Prescription Sleep Drugs

Hangover

Many people worry that, should they decide to take sleeping pills, they'll feel tired, fuzzy-headed, or dizzy; experience headaches or nausea; or have trouble waking up the morning after. These side effects are possible, but avoidable, says Ralph Downey III, PhD, director of the Loma Linda University Sleep Disorders Center in Loma Linda, Calif. If your doctor has prescribed the correct dosage, and you take the pill according to your doctor’s instructions, the medication should work effectively without any morning hangover, Downey says. Older drugs such as benzodiazepines are more likely to cause morning drowsiness or dizziness, because they have longer half-lives—meaning the effects take longer to wear off.
