Before Using diazepam
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For diazepam, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to diazepam 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 diazepam injection in infants. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of diazepam injection in the elderly. However, difficulty with breathing and heart attack are more likely to occur in the elderly, who are usually more sensitive than younger adults to the effects of diazepam injection. Elderly patients may require a lower dose to help reduce unwanted effects.

It is very important that your doctor check the progress of you or your child at regular visits to see if the medicine is working properly. Blood tests may be needed to check for any unwanted effects.

diazepam may cause some people, especially older persons, to become drowsy, dizzy, lightheaded, clumsy or unsteady, or less alert than they are normally. Also, diazepam may cause double vision or other vision problems. Make sure you know how you react to diazepam 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.
diazepam 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 or your child stop taking diazepam. Check with your doctor before taking any of the above while you or your child are using diazepam.
Do not stop taking it without checking with your doctor first. Your doctor may want you or your child 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.
