pharmacist
  • Ajovy (fremanezumab) is injected once every month. For adults, there's also an option to inject it once every 3 months. To help you remember when to inject the medication, you can put reminders on your calendar or phone.
  • If you miss your scheduled dose of Ajovy (fremanezumab), take your usual dose as soon as you remember. Then, your next injections will be once a month (or once every 3 months) from the date you injected your late dose.
  • After your Ajovy (fremanezumab) injection, the area might get red or sore. This usually happens within a couple hours of the injection and goes away on its own in a few days. Let your care team know if this reaction gets worse or doesn't go away.
  • Keep Ajovy (fremanezumab) in the carton it comes in to protect it from light. Store it in the refrigerator between 36ºF and 46ºF, but don't let it freeze it.
  • If needed (like for travel), you can keep Ajovy (fremanezumab) in the carton at room temperature up to 86ºF for up to 7 days. Keep it away from direct sunlight. Don't put it back in the fridge once it's at room temperature. Throw away Ajovy (fremanezumab) in a sharps container if it's out of the fridge for more than 7 days.

How to use Ajovy (fremanezumab):

  • Your prescriber or care team will train you on how to use Ajovy (fremanezumab). They'll make sure you or your caregiver knows how to inject it at home. Read the instructions for the autoinjector or the prefilled syringe. Ask your prescriber, pharmacist, or care team if you have any questions.
  • For children ages 6 to 12 years, a healthcare professional or an adult caregiver should give the Ajovy (fremanezumab) injection.
  • Each Ajovy (fremanezumab) autoinjector and prefilled syringe has 225 mg of medication. For once-monthly injections, you only need 1 autoinjector or syringe each time. But adults who inject once every 3 months will need to use 3 autoinjectors or syringes in a row for a total of 675 mg each time. Use a different spot on your skin for each injection to help prevent bruising or irritation.
  • When you're ready for your Ajovy (fremanezumab) injection: Take the medication out of the refrigerator. Lay it on a flat surface for 30 minutes so it reaches room temperature. Don't shake the medication or try to warm it up any other way (like in direct sunlight).
  • Before injecting Ajovy (fremanezumab): Always check that the medication it's either clear and colorless or slightly yellow. If it's cloudy, discolored, has particles (chunks), or frozen, don't use it. Also don't use it if any part of the autoinjector or syringe is broken or has any visible damage to it (e.g., cracks, leaks). Use a new one for the injection.
  • Where to inject Ajovy (fremanezumab): You can inject the medication into your stomach, at least 2 inches away from your belly button. Another spot is the front of your thighs, at least 2 inches above your knee and 2 inches below your groin. You can also inject into the fleshy area at the back of your upper arm with someone's help. Pick a slightly different area for each injection. Don't inject into tender, red, bruised, hard, or tattooed skin or areas with scars or stretch marks. This helps lessen bruising and skin irritation.
  • How to inject using the Ajovy (fremanezumab) autoinjector: Wash your hands and clean the injection area with an alcohol swab. Take off the cap and put the autoinjector against your skin at a 90-degree angle. Then, press it down on your skin for about 30 seconds. Keep holding it down until you hear two "clicks" and the blue plunger has filled the viewing window. Then, lift the autoinjector straight up.
  • How to inject using the Ajovy (fremanezumab) prefilled syringe: Wash your hands and wipe the injection area with an alcohol swab. Gently pinch up at least 1 inch of the skin. After taking off the needle cap, insert the needle into the fold of skin at a 45- to 90-degree angle with your other hand. Once the needle is all the way in, push the plunger slowly with your thumb. Push all the way down to inject all the medication. Then, pull the needle straight out.
  • After each Ajovy (fremanezumab) injection: Throw used autoinjectors and syringes into a sharps container. You can also use a heavy-duty container like an empty milk carton or laundry detergent bottle. This helps protect you and others safe from needle sticks.
