Reactions at the injection site
Ajovy is given as a subcutaneous injection, and it’s possible to have skin reactions around the area where you receive the shot. These are known as injection site reactions. In clinical studies, injection site reactions were the most common side effects reported with Ajovy.
Injection site reactions may include:
- pain or tenderness
- redness or other temporary change in skin color
Injection site reactions are usually mild and temporary. They tend to ease in a few hours to days.
What you can do
To help prevent injection site reactions, you can try using a different site each time you inject Ajovy. Sites you can use for your injection are:
- your belly (at least 2 inches from your belly button)
- front of your thighs (at least 2 inches above your knee and at least 2 inches below your groin)
- back of your upper arms
Your doctor may have you take Ajovy as one injection once every month. Or they may have you take it as three injections once every 3 months. If you need three injections for your dose, you can use the same injection site, such as your belly. However, you should use a slightly different spot for each injection.
To help prevent injection site reactions, it’s also important to carefully follow the instructions for using Ajovy. Here are some key points:
- Before giving yourself an injection, allow Ajovy to reach room temperature after you take it out of the refrigerator. You should not warm up the medication by heating it, such as with hot water or a microwave.
- You should avoid injecting Ajovy into areas of skin that are tender, discolored, bruised, or hard. And you should not inject the medication into areas that have tattoos, scars, or stretch marks.
- If you inject other medications, choose different spots than where you inject Ajovy.
- After injecting Ajovy, press gently on the injection site with a clean cotton ball or gauze pad for a few seconds.
- You should try not to rub the injection site.
If you have an injection site reaction that bothers you, it may help to apply an ice pack to the affected area. If the reaction is severe or lasts longer than a few days, be sure to talk with your doctor or pharmacist. They can recommend possible treatments for injection site reactions.
As with most drugs, Ajovy can cause an allergic reaction in some people. But these reactions aren’t common. When they do occur, they’re typically mild or moderate. Serious allergic reactions are rare.
Allergic reactions can occur within hours after receiving Ajovy. They can also happen for up to a month after having an injection.
Symptoms of mild or serious allergic reactions can include:
- skin rash
- swelling under your skin, typically in your lips, eyelids, feet, or hands
- swelling of your mouth, tongue, or throat, which can make it hard to breathe
What you can do
For mild symptoms of an allergic reaction, call your doctor right away. They may recommend ways to ease your symptoms and determine whether you should keep using Ajovy.
But if your symptoms are serious and you think you’re having a medical emergency, immediately call 911 or your local emergency number. You may need treatment with medications such as corticosteroids. If you have a serious allergic reaction, your doctor will likely recommend that you stop using Ajovy.
