Before Using

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 this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine 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.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of triazolam in the pediatric population. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of triazolam in the elderly. However, severe drowsiness, dizziness, confusion, clumsiness, or unsteadiness are more likely to occur in the elderly, which may require an adjustment in the dose for patients receiving triazolam.

Precautions

If your condition does not improve within 7 to 10 days, or if it becomes worse, check with your doctor.

Using this medicine 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.

Do not take itraconazole (Sporanox®), ketoconazole (Nizoral®), nefazodone (Serzone®), or certain HIV medicines (eg, indinavir, nelfinavir, lopinavir, ritonavir, saquinavir, Kaletra®, Norvir®) while you are using this medicine. Using these medicines together with triazolam may increase the chance of serious side effects.

Triazolam may cause serious allergic reactions, including anaphylaxis and angioedema, which can be life-threatening and require immediate medical attention. Call your doctor right away if you have itching, hives, hoarseness, nausea or vomiting, trouble breathing, trouble swallowing, or any swelling of your hands, face, mouth or throat while you are using this medicine.

This medicine may be habit-forming. If you feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.

This medicine may cause you to do things while you are still asleep that you may not remember the next morning. It is possible you could drive a car, sleepwalk, have sex, make phone calls, or prepare and eat food while you are asleep or not fully awake. Tell your doctor right away if you learn that any of these has happened.

This medicine 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 this medicine. Check with your doctor before taking any of the above while you are using this medicine.

This medicine may cause some people, especially older persons, to become drowsy, dizzy, or less alert than they are normally, which may lead to falls. Even though triazolam is taken at bedtime, it may cause some people to feel drowsy or less alert the next morning. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.

Do not stop using this medicine without checking first with your doctor. 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), stomach or muscle cramps, sweating, tremors, vomiting, or unusual behavior.

If you develop any unusual and strange thoughts or behavior while you are using triazolam, be sure to discuss it with your doctor. Some changes that have occurred in people using this medicine are like those seen in people who drink alcohol and then act in a manner that is not normal. Other changes may be more unusual and extreme, such as confusion, worsening of depression, hallucinations (seeing, hearing, or feeling things that are not there), suicidal thoughts, and unusual excitement, nervousness, or irritability.

If you think you or someone else may have taken an overdose of this medicine, get emergency help at once. Taking an overdose of triazolam or taking alcohol or other CNS depressants with triazolam may lead to serious breathing problems and unconsciousness. Some signs of an overdose include: severe drowsiness, severe nausea or vomiting, staggering, and troubled breathing.

Using this medicine while you are pregnant may cause neonatal withdrawal syndrome in your newborn babies. Tell your doctor right away if your baby has an abnormal sleep pattern, diarrhea, a high-pitched cry, irritability, shakiness or tremors, weight loss, vomiting, or fails to gain weight.

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.
