Before Using lorazepam

Tell your doctor if you have ever had any unusual or allergic reaction to lorazepam or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of lorazepam in children under 12 years of age. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of lorazepam in the elderly. However, severe drowsiness or unsteadiness are more likely to occur in the elderly, who are usually more sensitive than younger adults to the effects of lorazepam. Elderly patients may require a lower dose to help reduce unwanted effects.

Precautions While Using lorazepam
It is very important that your doctor check your progress at regular visits to allow for changes in your dose and to check for any unwanted effects. Blood tests may be needed to check for any unwanted effects.
Using lorazepam 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 the medicine, tell your doctor right away.
lorazepam may cause drowsiness, trouble with thinking, trouble with controlling movements, or trouble with seeing clearly. Make sure you know how you react to lorazepam before you drive, use machines, or do anything else that could be dangerous if you are not alert or able to think or see well.
Do not stop taking it 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.
lorazepam will add to the effects of alcohol and other central nervous system (CNS) depressants. CNS depressants are medicines that slow down the nervous system, which may cause drowsiness or make you less alert. Some examples of CNS depressants are antihistamines or medicine for hay fever, 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 lorazepam. Check with your doctor before taking any of the above while you are using lorazepam.
