What are different injection techniques for treating asthma?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am concerned about Tezspire injection training. The nurse mentioned a siterotation different from my previous Fasenra shots. I am getting some injection site reactions that last four to five days. I also noticed increased mucus production but better peak flow readings (up from 350 to 425). Is this normal? Should I adjust my other asthma medications as Tezspire starts working? Also, do these reactions subside over time, or should I switch to a different injection technique?

Kindly suggest.

Thanks.

Hi,

Welcome to icliniq.com.

I can understand your concern.

It sounds like you are having a mixed experience with Tezspire (Tezepelumab), and I can understand your concerns. Here is a breakdown of your questions:

  1. Injection site reactions: It is common to experience red welts or localized reactions after Tezspire injections, especially in the beginning. These reactions, such as redness or swelling, typically go away within a few days (four to five days in your case sounds pretty typical). If they persist or become more painful, it is worth contacting your healthcare provider to ensure proper technique and rule out other issues, but generally, site reactions do tend to subside over time as your body adjusts. If the welts are consistently troublesome, you can discuss adjusting your injection technique or rotating sites differently, as the nurse mentioned. Some people find rotating the injection site more frequently can help minimize irritation.

  2. Mucus production versus peak flow improvement: Increased mucus production initially, is something some patients report, but the positive change in your peak flow readings (up from 350 to 425) suggests that Tezspire is likely helping with your asthma control. Peak flow improvement is a great sign that Tezspire is working. Mucus production might take a little longer to settle down, but it is not uncommon as your body adjusts to the medication. Your lungs could be clearing out excess mucus as they begin functioning better, so this may resolve with time.

  3. Adjusting other medications: As Tezspire begins to work, you should follow up with your healthcare provider regarding your other asthma medications. In some cases, once a biologic like Tezspire starts showing effectiveness, the dose of other medications (such as oral steroids or other biologics) might be adjusted, but this is something your doctor will guide. If your asthma control improves, you might be able to reduce other medications, but never adjust without consulting your doctor first.

Be in close contact with your pulmonologist. Monitoring is essential.

I hope this information will help you.

Thanks.
