Yes, Ativan (lorazepam) withdrawal can cause twitching, also known as myoclonus. Other possible symptoms of Ativan withdrawal include anxiety, irritability, insomnia, sweating, headache, muscle pain, tremors, seizures, and more. It is important to seek medical attention if you are experiencing any of these symptoms during or after discontinuing Ativan use, as withdrawal can be dangerous or even life-threatening in some cases. A healthcare professional can guide you through a safe and effective tapering process to minimize the risk of withdrawal symptoms.
