How should this medicine be used?
Fremanezumab-vfrm injection comes as a solution (liquid) in a pre-filled syringe and as a pre-filled autoinjector to be injected subcutaneously (under the skin). It is usually given once a month (as 1 injection) or once every 3 months (as 3 separate injections, one after the other). Use fremanezumab-vfrm injection on about the same day every 1 to 3 month (s), depending on your dose. Follow the directions on your prescription label carefully and ask your doctor or pharmacist to explain any parts you do not understand. Use fremanezumab-vfrm injection exactly as directed. Do not use more or less or use it more often than prescribed by your doctor.
You may be able to inject the medicine yourself at home or ask a friend or family member to give you the injections. Ask your doctor to show you or the person who will be giving the injections how to inject the medicine.
Fremanezumab-vfrm injection comes as a pre-filled syringe and a pre-filled autoinjector. Allow the syringe and autoinjector to warm up to room temperature for 30 minutes away from direct sunlight before injecting the medicine. Do not try to warm the medicine by heating it in a microwave, placing it in hot water, or by any other method. Use each syringe or autoinjector only once and inject all of the solution into the syringe or autoinjector. Dispose of used syringes or autoinjector in a puncture resistant container. Talk to your doctor or pharmacist about how to dispose of the puncture resistant container.
Inject fremanezumab-vfrm into the thigh, upper arm, or stomach area. Do not inject into an area where the skin is tender, thick, bruised, red, scaly, hard, or with scars or stretch marks.
Always look at fremanezumab-vfrm before injecting it. It should be clear and colorless. Do not use fremanezumab-vfrm injection if it is colored, cloudy, or contains flakes or solid particles. Do not shake it.
If your doctor tells you to inject three separate injections one after the other, use a different syringe or autoinjector for each injection. If you use the same site on the body (upper arm, thigh, or stomach) for separate injections, make sure that each injection is not in exactly the same place that it was used for the other injections.
