Ambien side effects may include daytime drowsiness, feeling “drugged” or light-headed, headache, diarrhea, nausea, vomiting, muscle pain, or blurred vision. Other, more serious Ambien side effects may also occur.

Some side effects can be very serious and get emergency medical help if you have any of these signs of an allergic reaction: hives, difficulty breathing, swelling of your face, lips, tongue, or throat.

Stop using Ambien and call your doctor at once if you have any of these serious side effects: worsening sleep problems, depressed mood, thoughts of hurting yourself, unusual risk-taking behavior, decreased inhibitions, no fear of danger, aggression, feeling agitated, hallucinations, confusion, loss of personality.

Continue taking Ambien and talk to your doctor if you have any of these less serious side effects: daytime drowsiness, dizziness, weakness, feeling “drugged” or light-headed, weakness, lack of coordination, amnesia, forgetfulness, headache, vivid or abnormal dreams, diarrhea, nausea, vomiting, muscle pain, or blurred vision.

Ambien is used to treat insomnia. Ambien is a sedative, also called a hypnotic, which affects chemicals in your brain that may become unbalanced and cause sleep problems (insomnia). This medication causes relaxation to help you fall asleep and stay asleep.

Ambien side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.

Remember that all medications/drugs can cause gastrointestinal symptoms and can be toxic to your liver.
