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 lorazepam tablets and oral liquid in children younger than 12 years of age and extended-release capsules in children. 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 lorazepam in the elderly. However, elderly patients are more likely to have unwanted effects (eg, severe drowsiness or unsteadiness) and age-related kidney, liver, or heart problems, which may require caution and an adjustment in the dose.
Breastfeeding
Studies in women suggest that this medication poses minimal risk to the infant when used during breastfeeding.

Precautions
It is very important that your doctor check your or your child's progress at regular visits to see if this medicine is working and allow for changes in the dose. Blood tests may be needed to check for any unwanted effects.
Tell your doctor if you are pregnant or planning to become pregnant. Using this medicine during the later part of a pregnancy may cause problems in your newborn baby (eg, sedation or withdrawal symptoms). Tell your doctor right away if your baby has an abnormal sleep pattern, diarrhea, feeding problems, a high-pitched cry, irritability, low muscle tone, restlessness, shakiness or tremors, sluggishness, trouble breathing, weight loss, vomiting, or fails to gain weight. If you think you have become pregnant while using the medicine, tell your doctor right away.
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.
If you develop any unusual and strange thoughts or behavior while you are taking lorazepam be sure to discuss it with your doctor. Some changes that have occurred in people taking 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), thoughts of killing oneself, and unusual excitement, nervousness, or irritability.
This medicine may cause drowsiness, trouble with thinking, trouble with controlling movements, or trouble with seeing clearly. Make sure you know how you react to this medicine 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.
Symptoms of an overdose include: blurred vision, change in consciousness, confusion, dizziness, faintness, or lightheadedness when getting up suddenly from a lying or sitting position, hallucinations, increased sweating, loss of consciousness, loss of strength or energy, muscle pain or weakness, nightmares, shakiness and unsteady walk, slow or irregular heartbeat, sweating, trouble in speaking, unsteadiness, trembling, or other problems with muscle control or coordination, trouble sleeping, unusual excitement, nervousness, restlessness, or irritability, or unusual tiredness or weakness. Call your doctor right away if you notice these symptoms.
This medicine may cause respiratory depression (serious breathing problem that can be life-threatening), especially when used with narcotic pain medicines. Tell your doctor if you are using any narcotic medicine.
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, including hallucinations, headache, seizures, stomach or muscle cramps, tremors, trouble sleeping, or unusual behavior.
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 or medicine 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.
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.
