I took flagyl 400 mg two tablet at once meaning 800 mg in total a day for a period of three days after that i stopped because of severe symptoms of confusion and blurry vision and feeling paralyzed. when will the symptoms go away its been 6 days?

Presence of liver disease can prolong the side effects and abstinence from alcohol for at least 3 days after coming off flagyl is very important. I would think effects of 800 mgs daily for 3 days would have improved after 6 days. Discuss this with your prescribing physician and get instructions and advice. Your pharmacist may have more information for you.
