I took it for 3 days with extreme nausea, some heart racing, palpitations, headache, restless leg and insomnia. Then 4th day, I was afraid I needed to go to the ER - extreme heart racing, palpitations, numbness in left arm, tingling in hands and feet and feeling like I was about to faint. I waited it out for an hour and a half and is slowed down. But now after about 18 hours, my fingers are still tingly and feeling heartbeat in my neck. My dermatologist prescribed it for an infection after a derma-filler injection. The side effects were not discussed. My ENT agreed that the med was best for my infection but did not seem concerned over the initial symptoms. I have a heart murmur and cannot take anything containing pseudoephrine - this med acts like a mega dose of it!
