muscle spasm
"Zanaflex is great for muscle spasms as I have them from Osteoarthritis in my spine, also spinal stenosis. If you are on any heart meds, please use the interactions checker because it may cause severe drops in blood pressure. I am taking Lisinopril, Hydrochlorothiazide and Metoprolol for heart arrhythmias and my blood pressure was dropping to dangerous levels. All of my specialists knew what medicines I was taking, but none of them noticed the interactions. I checked them myself here at Drugs.com and found the RED FLAGS myself, so be careful."
