What side effects can Stelara (ustekinumab) cause?
Stelara (ustekinumab) can cause side effects ranging from mild reactions to more serious infections. Commonly reported effects include injection-site reactions (such as redness, swelling, or pain) and upper respiratory symptoms (like runny nose or sore throat). It can also raise the risk of infections because it changes parts of the immune system involved in inflammation.
What are the most serious Stelara side effects to watch for?
Seek urgent medical care if you develop signs of a serious infection, such as fever, chills, persistent cough, shortness of breath, or feeling very unwell. People on Stelara may also need monitoring for tuberculosis (TB) before starting and for infections that occur during treatment. Allergic reactions can also happen, including rash, hives, swelling, or trouble breathing.
Can Stelara increase the risk of infections or TB?
Yes. Because Stelara suppresses certain immune pathways, it can increase susceptibility to infections. Clinicians typically screen for TB before starting and monitor for symptoms during treatment.
Who may be more likely to have side effects?
Risk can be higher for people with a history of recurrent infections, untreated or latent TB, chronic or serious infections, or significant immune suppression. The risk profile can also depend on other medications used alongside Stelara.
What should I do if I miss a Stelara dose?
Missing doses can affect symptom control and disease course. The correct next step depends on your dosing schedule (every 4 weeks or every 8 or 12 weeks depending on indication and prescriber instructions). Contact your prescriber or pharmacist for specific guidance.
Are there alternatives if Stelara isn’t tolerated?
If side effects are significant or infections occur, prescribers may consider other treatments for the underlying condition (for example, other biologics or non-biologic options). The best choice depends on whether the issue is infection risk, injection reactions, or other tolerability problems.
