Temazepam is used to help people who suffer from insomnia fall asleep and stay asleep. Temazepam works to produce a calming effect by altering unbalanced chemicals within the brain. Temazepam is a drug used in the treatment of insomnia. As insomnia is not recommended to be treated in long-term medicinal courses, temazepam is only used for short-term treatment which is around around 3 weeks. Temazepam belongs to the benzodiazepine class of drugs, a class which works by enhancing the effects of GABA - the predominant inhibitory neurotransmitter in the brain. By enhancing the effects of GABA, there is less excitation in the brain, thereby helping the patient to sleep. Temazepam is associated with its own range of potential side effects. Among them include dizziness, headache, nausea, anxiety, drowsiness, and a hangover effect. Obese patients are more likely to experience side effects because it takes longer for the body to eliminate the drug.
