Allie asked

I am currently experiencing some severe anxiety and have already taken 2 MG Sublingual Ativan in 2 hours. My dosing is 3 MG per day as needed. What is the maximum dose I an safely take if necessary?

Answer

The maximum daily dose of Ativan (lorazepam) is 10 mg per day, when taking the oral dosage form. There is no listed maximum daily dose for the intramuscular or intravenous formulations as necessary dosages are very much dependent upon indication and effect.

It is important to not adjust or increase your dose unless you have consulted with your doctor. Ativan, while effective, can cause significant physical dependence and the risk of side effects is greatly increased when higher doses are used.

Initial dosages start at 2 to 3 mg/day in 2 to 3 divided doses. Doses should be gradually increased as needed as long as the medication is well tolerated. The typical effective dose for the average patient is 2 to 6 mg per day, but can range from 1 to 10 mg per day.
