This helps the solution disperse correctly. The injection site should be swabbed with a disinfectant to remove any surface bacteria. Clean about two inches around the point where the needle will go in and let the disinfectant dry for at least one minute before proceeding. Pushing in with a quick thrust causes the least discomfort. If the needle is correctly positioned it will be difficult to draw back on the plunger.
Any blood drawn into the syringe means the needle tip has penetrated a vein or artery.
Once the needle is properly placed, depress the plunger slowly and steadily, so the solution is correctly injected and the skin or muscle tissue is not damaged. Pull the syringe out quickly and apply pressure to the site with a swab containing disinfectant. A gentle massage of the site while still maintaining pressure- helps disperse the Follistim solution and relieve any discomfort. Use the disposable syringe only once and dispose of it properly. Protect from light.
