Thank you for the good advice. I too look up each new drug on Drugs.com. Some of my fainting occurred 4 hours after I injected the generic of Forteo, Teriparitide. Since I quit it I read it can cause fainting in certain people and I have not fainted again. I did think about heart issues but passed two in depth physicals ten months apart before I had two recent joint replacements. We have advocate for ourselves and read to educate ourselves. Best wishes.
