Before Using estazolam

Precautions While Using estazolam
It is very important that your doctor check your progress at regular visits to make sure estazolam is working properly. Blood tests may be needed to check for unwanted effects.
Using estazolam while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant. If you think you have become pregnant while using estazolam, tell your doctor right away. Do not breastfeed while you are using estazolam.
Do not take itraconazole (Sporanox®) or ketoconazole (Nizoral®) while you are using estazolam. Taking these medicines together with estazolam may increase the chance of serious side effects.
Estazolam may cause some people, especially older persons, to become drowsy, dizzy, or less alert than they are normally. Even though estazolam is taken at bedtime, it may cause some people to feel drowsy or less alert the next morning. Make sure you know how you react to estazolam before you drive, use machines, or do anything else that could be dangerous if you are dizzy, not alert, or not able to think or see well.
If you develop any unusual or strange thoughts and behavior while taking estazolam, be sure to discuss it with your doctor. Some changes that have occurred in people taking estazolam are like those seen in people who drink too much alcohol. Other changes might be confusion, worsening of depression, hallucinations (seeing, hearing, or feeling things that are not there), suicidal thoughts, and unusual excitement, nervousness, or irritability.
Estazolam may cause sleep-related behaviors such as driving a car (sleep-driving), walking (sleep-walking), having sex, making phone calls, or preparing and eating food while you are asleep or not fully awake. If these reactions occur, tell your doctor right away.
Estazolam will add to the effects of alcohol and other CNS depressants (medicines that slow down the nervous system, possibly causing drowsiness). Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; barbiturates (used for seizures); muscle relaxants; or anesthetics (numbing medicines), including some dental anesthetics. This effect may last for a few days after you stop taking estazolam. Check with your doctor before taking any of the above while you are using estazolam.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
Do not stop taking estazolam without checking with your doctor first. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This may help prevent a worsening of your condition and reduce the possibility of withdrawal symptoms, such as convulsions (seizures), hallucinations, stomach or muscle cramps, tremors, or unusual behavior.
Avoid smoking while you are using estazolam.
If your condition does not improve within 7 to 10 days, or if it becomes worse, check with your doctor.
