Common OTC sleep aids
Various OTC sleep aids are available in any pharmacy. Most of these medications contain antihistamines, which can cause drowsiness. Store brands containing the same active ingredients as brand-name sleep aids are commonly available. Store brands have the same risks and benefits as their brand-name counterparts, often at a more reasonable cost.
Talk to your doctor before taking any OTC sleep aid if you're currently taking an antidepressant in the class of drugs called monoamine oxidase inhibitors (MAOIs) — such as phenelzine (Nardil) or tranylcypromine (Parnate) — or did so as recently as two weeks ago. Also check with your doctor first if you take any other drugs for depression, psychiatric or emotional conditions, or Parkinson's disease.
Although antihistamine-based medications may improve mild symptoms of insomnia for a short period of time, they aren't likely to help for longer than a couple of weeks.
Here are some common OTC sleep aids:
Diphenhydramine (Sominex, Benadryl, Tylenol PM, others)
These may cause:
This medication may cause prolonged drowsiness. It also may not be safe if you're pregnant or breast-feeding or you have a history of:
Dietary supplements
Various dietary supplements have been touted as effective insomnia treatments, but there's much that isn't known about their effectiveness or safety. The most widely publicized may be the hormone melatonin and the herb valerian.
Melatonin
Melatonin is thought to help control your body's internal clock. The melatonin supplements most often found in health food stores and pharmacies are manufactured versions of the natural hormone. These supplements are most helpful for people experiencing jet lag or the effects of shift work. They have less and inconsistent effects as a sleep aid. There are many unanswered questions about melatonin. Some people who've taken melatonin have reported:
Melatonin may interact with a variety of common drugs, so talk with your doctor before trying it. The best dose isn't certain, and the long-term effects are unknown.
Melatonin may not be safe if you're:
Supplements made from this plant may reduce the amount of time it takes to fall asleep and help you sleep better. However, it's not clear what the active ingredient is. Also, the potencies of various ingredients vary from preparation to preparation.
Although the Food and Drug Administration considers valerian to be generally safe, side effects may include:
Taking sleeping pills
If your best attempts to get a good night's sleep have failed, your best bet is to make an appointment with your doctor. Often, specific causes for insomnia may be found that are reversible. Nondrug approaches including cognitive behavioral therapy can be effective. Prescription sleeping pills may be both effective and safe, if taken as prescribed. Consider OTC sleep aids or supplements with caution.

- Start with your doctor. You don't need your doctor's OK to take an over-the-counter sleep aid, but it's a good idea to check with your doctor anyway. He or she can make sure the sleep aid won't interact with other medications or medical conditions. Your doctor can also help you determine the best dosage. In some cases, your doctor may recommend prescription sleeping pills. If you and your doctor decide further evaluation is needed, you may be referred to a sleep specialist.
- Take it one day at a time. Sleep aids are a temporary solution for insomnia. Most over-the-counter varieties are intended to be used for only two to three nights at a time. Taken too often, some sleep aids may cause rebound insomnia — sleeplessness that returns in full force when you stop taking the medication.
- Avoid alcohol. Never mix alcohol and sleep aids. Alcohol increases the sedative effects of the pills. Even a small amount of alcohol combined with sleep aids can make you feel dizzy, confused or faint.
- Quit carefully. When you're ready to stop taking sleep aids, follow your doctor's instructions or the directions on the label. Some medications must be stopped gradually.
- Watch for side effects. If you feel sleepy or dizzy during the day, talk to your doctor about changing the dosage or discontinuing the pills.
