I am taking 10mg of Donopezil to help with my memory loss. I have been having moderate to severe muscle spasms for the past month. I have been taking this for approximately 5 months. The only other medication I take is Coumadin which I have been taking since November 2017 due to a deep vein thrombosis in my right ankle. The thrombosis has cleared but my hematologist wanted me to stay on Comadin til I am rechecked in June. Any suggestions would be appreciated. I am 80 years young. I do 1 hour of yoga a day and cycle 10 miles 5 days a week. I also do some strenuous yard work clearing brush and small trees 3 to 4 days a week getting ready for a builder to start building our new home. Thank you.
