Estazolam belongs in the class of prescription drugs known as benzodiazepines, which should only be prescribed by a healthcare practitioner. Estazolam should not be used by people with an allergy to any benzodiazepines, such as Valium (the brand name for diazepam), Restoril (temazepam) and Ativan (lorazepam), or those individuals affected by the neuromuscular disorder myasthenia gravis or by sleep apnea. Benzodiazepines, including estazolam, should be used with caution in certain groups, including the elderly, people with respiratory (breathing), kidney or liver problems, people with depression, and those with a history of substance abuse. As well, benzodiazepines, including estazolam, are not recommended for use in pregnant or breastfeeding women or in children under the age of 18. The side-effects associated with estazolam vary according to the individual and can include headache, dizziness, drowsiness, sleep-related behaviours such as sleep-driving, behavioural changes, confusion, anxiety, depression, and breathing problems. Estazolam may interact with other drugs, including alcohol, which can lead to increased side-effects.

People can experience withdrawal symptoms when they stop taking estazolam. Withdrawal symptoms can range from anxiety and sleeplessness, to abdominal and muscle cramps, vomiting, sweating, tremors and convulsions, and is usually associated with taking higher doses of estazolam for a longer period of time.
