Zaleplon (also known under the brand name Sonata) is a non-benzodiazepine central nervous system (CNS) depressant that is usually used for the short-term treatment of insomnia and other sleep disorders.
Zaleplon works by increasing the amount of the neurotransmitter GABA in the brain which slows down brain activity, making it easier to get a full night’s sleep.
This prescription drug is also classified as a Schedule IV controlled substance, which means that it has a relatively low potential for abuse and dependence. However, zaleplon is still habit-forming and is associated with side effects, adverse events, and warnings.

There are also several medical conditions that zaleplon does not work well with.
Zaleplon can actually make the following conditions worse:
- lung disease

- kidney disease
- liver disease
- drug or alcohol addiction
Taking zaleplon is also not recommended for those who are pregnant or breastfeeding. For those who are breastfeeding, the drug can transfer from the breast milk to the baby and lead to serious side effects.
If you are pregnant and taking zaleplon, talk to your healthcare provider. They can put you on a different medication or they can tell you exactly what the risks are if you can’t quit taking the sleep medicine.
If you are allergic to any of the ingredients in zaleplon, aspirin, or tartrazine (a yellow dye), zaleplon is probably not the right medication for you.
Symptoms of an allergic reaction may include:
- swelling of the face, throat, tongue, lips, or eyes
- difficulty breathing or swallowing
One of the major risks that come with abusing zaleplon or taking higher than recommended doses is overdose. A zaleplon overdose can be life-threatening if left untreated.
If you or a loved one shows any of the following signs and symptoms, call 911 immediately:
- severe drowsiness
- low blood pressure
- feeling sluggish
- troubled breathing/respiratory depression
- problems with coordination
- floppy muscles
Zaleplon abuse may not be common, but when it does occur, it can lead to dependence. When you build up a dependence on the drug and then quit taking it, withdrawal symptoms are likely to show up. This is your body’s response to the absence of a drug that it has gotten used to.
Zaleplon withdrawal symptoms may include:
- muscle weakness
- rebound insomnia
- trouble sleeping
