Can Tezspire cause joint pain in asthma patients?

Question

Hi doctor,

My wife, who is 44 years old, started Tezspire two months ago for severe asthma. However, she has developed unusual red rashes on her chest and arms after each injection. These rashes last for approximately three days before fading. Although her breathing has improved, she is also experiencing joint pain, which she has never had before. Her pulmonologist is currently on vacation, and we have been unable to obtain a clear response from anyone at the clinic.

Are these symptoms normal side effects of the medication?
Should she proceed with the next scheduled dose next week, or would it be better to wait until these symptoms resolve?

Please help me.

Hi,

Welcome to icliniq.com.

I can understand your concern.

I am glad to hear that your wife is experiencing improved breathing since starting Tezspire. However, the new symptoms you have described, recurrent red rashes after each injection and new-onset joint pain, should be taken seriously.

While Tezspire (Tezepelumab) is generally well tolerated, skin reactions such as rash, redness, or itching, and joint pain (arthralgia) have been reported in some patients, although these are not among the most common side effects. The pattern you have noticed of symptoms occurring after each injection and resolving within a few days suggests a possible delayed hypersensitivity reaction to the medication.

Even though her respiratory symptoms have improved, it is important not to overlook these new developments. I would advise against proceeding with the next scheduled dose until her treating specialist or a covering physician evaluates the situation. Continued dosing could potentially worsen the reactions or trigger more severe side effects over time.

In the meantime, you should:

Document the timing, severity, and duration of each reaction. Photographs can be helpful.
Monitor for any systemic symptoms such as facial swelling, difficulty breathing, or high fever, which would require urgent medical attention.
Request that the clinic arrange for a covering pulmonologist or allergist-immunologist to review her case while her doctor is away.

You have done the right thing by staying alert and asking questions. Tezspire is a promising treatment, but like all biologic therapies, it must be balanced carefully with each patient’s immune response.

Feel free to ask if you need any more clarification or help with your questions.
