Sleeping pills have side effects like most medications. You won't know, though, whether you will experience side effects with a particular sleeping pill until you try it. Your doctor may be able to alert you to the possibility of side effects if you have asthma or other health conditions.

Sleeping pills make you breathe more slowly and less deeply. That can be dangerous for people with uncontrolled lung problems such as asthma or COPD. It's important to be aware of possible sleeping pill side effects so you can stop the drug and call your doctor immediately to avoid a more serious health problem.

Are There More Complex Sleeping Pill Side Effects? Some sleeping pills have potentially harmful side effects, including parasomnias. Parasomnias are behaviors and actions over which you have no control, like sleepwalking.

During a parasomnia, you are asleep and unaware of what is happening. Parasomnias with sleeping pills are complex sleep behaviors and may include sleep eating, making phone calls, or having sex while in a sleep state. Sleep driving, which is driving while not fully awake, is another serious sleeping pill side effect.

Though rare, parasomnias are difficult to detect once the medication takes effect. In March 2007, the FDA requested that all pharmaceutical manufacturers of sedative-hypnotic drug products reinforce product labeling to include stronger language about the potential risks of taking a sleeping pill. Because complex sleep behaviors are more likely to occur if you increase the dosage of a sleeping pill, take only what your doctor prescribes -- no more.
