Insomnia
Ativan (lorazepam) is a prescription medicine that belongs to the group of drugs called benzodiazepines. It may be prescribed alone or in combination with other medications for sleep issues, anxiety, or epilepsy.
It is believed that Ativan works by increasing the activity of certain natural chemicals (neurotransmitters) in the brain. Specifically, Ativan mimics GABA, your body’s natural “rest and relaxation” neurotransmitter. This helps you fall asleep faster, wake up less often, and stay asleep longer.
Ativan may also be given to treat irritable bowel syndrome, nausea and vomiting caused by cancer treatment, or alcohol withdrawal to control the agitation.

The right Ativan dosage for you depends on factors like your age, medical conditions, and other medications. The healthcare provider who prescribed Ativan for you is in the best position to answer this question.
In general, the minimum dosage that offers you a more restful night of sleep is best. Typically, Ativan for sleep is prescribed to be taken about ½ to 1 hour before bed as needed. This minimizes side effects of Ativan, like dependence, sleepiness during the day, and poor balance.
Ativan comes in 0.5, 1, and 2 mg sizes in two different pill formats. The oral pill should be swallowed with a sip of water, while the sublingual pill should be dissolved under the tongue.
It would be best to inform your physician about prescription and non-prescription medications, including nutritional supplements, vitamins, and herbal supplements. Some medications, like prescription painkillers, can enhance the effect of Ativan and cause too much sedation.
You should inform your doctor if you have glaucoma. Also, if you have or had lung disease, heart disease, liver disease, or seizures, you should inform your physician.
You should also inform your doctor if you are pregnant or are breastfeeding. You should immediately call your doctor if you get pregnant while on Ativan treatment.
Ativan may make you drowsy. Do not drive or operate any machinery until you know how this medication affects your alertness. Do not combine alcohol with Ativan.

In general, the minimum possible dosage that offers you a more restful night of sleep is best. This may be as low as 0.25 to 0.5 mg if you are an older adult, or 1 mg for younger people. Typically, Ativan for sleep is prescribed to be taken about ½ to 1 hour before bed as needed. This minimizes side effects of Ativan, like dependence, sleepiness during the day, and poor balance.
Ideally, Ativan should be used on an occasional or short term basis for sleep. When you take Ativan regularly over the long term, you put yourself at higher risk of serious side effects like becoming dependent, having poor balance and falls, and being drowsy during the day.
If you find you need to take Ativan every night, talk to your healthcare provider about what else you can do to get better sleep. They can help you gradually wean from Ativan and find alternative sleep remedies for you.
Ativan can make you tired and drowsy the next day. That is why it is best to take the minimum effective dose so you are less likely to be affected during the day. Be cautious when driving or operating machinery after taking Ativan.
Xanax and Ativan both belong to the benzodiazepine class of the drugs. Both are prescribed for anxiety, sleep-related disorders, and other psychiatric disorders.
Compared to Ativan, Xanax has a quicker onset of action but has a shorter duration of action. This means the sedative effect may occur more quickly with Xanax than Ativan, but the effect will wear off more quickly than Ativan.
Your doctor assesses your medical history to decide which medication is likely to work best for you. Sometimes, you may find you don’t respond well to the first medication you try. Talk to your doctor to see if the other medication will work better for you.
Ativan tablets will start showing its effect in 20-30 minutes. The sedation effects last around 6 to 8 hours.
Urine samples show the presence of Ativan or its metabolites for one to six weeks. Ativan presence in the urine depends upon the dose and duration of the treatment. A urine test can detect Ativan up to six days after the last use of the drug.
Ativan can slow heart rate and decrease blood pressure. These effects may be considered as mild side effects of the drug. If Ativan is prescribed for a long time, Ativan may cause the following heart problems:
