Lorazepam belongs to a group of drugs called benzodiazepines. It is thought that lorazepam works by enhancing the activity of certain neurotransmitters in the brain.
Lorazepam is used to treat anxiety disorders and seizure disorders.
It is dangerous to purchase lorazepam on the Internet or outside the United States. The sale and distribution of medicines outside the U.S. does not comply with safe-use regulations of the Food and Drug Administration (FDA). These medications may contain dangerous ingredients, or may not be distributed by a licensed pharmacy.
Important Information
You should not use lorazepam if you have narrow-angle glaucoma, severe respiratory insufficiency, myasthenia gravis, or if you are allergic to Valium or a similar medicine.
Do not use lorazepam if you are pregnant. This medicine can cause birth defects or life-threatening withdrawal symptoms in a newborn.
Lorazepam may be habit-forming and should be used only by the person it was prescribed for. Misuse of habit-forming medicine can cause addiction, overdose, or death. This medicine should never be shared with another person, especially someone who has a history of drug abuse or addiction. Keep the medication in a secure place where others cannot get to it.
Fatal side effects can occur if you take lorazepam with alcohol, opioid medicine, or other drugs that cause drowsiness or slow your breathing.
Before taking this medicine
You should not take lorazepam if you have:
- narrow-angle glaucoma; or
- a history of allergic reaction to any benzodiazepine (diazepam, alprazolam, Ativan, Klonopin, Restoril, Tranxene, Valium, Versed, Xanax, and others).
To make sure lorazepam is safe for you, tell your doctor if you have:
- breathing problems such as COPD (chronic obstructive pulmonary disease) or sleep apnea (breathing that stops during sleep);
- drug or alcohol addiction;
- depression, mood problems, or suicidal thoughts or behavior;
- kidney or liver disease;
- seizures; or
- glaucoma.
If you use lorazepam while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks.
You should not breastfeed while using lorazepam.
