Is lorazepam still effective to take after 5 years?

Lorazepam can still be effective after five years, but its efficacy may vary based on individual factors such as tolerance, dosage, and the specific condition being treated. Long-term use can lead to tolerance, meaning higher doses may be needed to achieve the same effect. It's important to consult a healthcare provider to assess its continued appropriateness and to discuss potential risks, including dependence and withdrawal symptoms. Regular monitoring and evaluation can help determine the best course of action.
