What are the initial side effects of Stelara (ustekinumab)?
While Stelara is generally well-tolerated, some people may experience side effects when starting treatment. Hair loss has been reported by some MyPsoriasisTeam members as one of the most common initial side effects, though clinical trials haven't directly linked this to Stelara alone. The hair loss could be related to psoriasis itself or to other medications like methotrexate that are sometimes used alongside Stelara. The good news is that many people report positive long-term experiences with Stelara. For example, some MyPsoriasisTeam members have reported being almost completely clear of psoriasis symptoms after just a couple of injections, with minimal side effects over extended periods of treatment.
If you experience concerning side effects when starting Stelara, discuss them with your dermatologist. They can help determine if the side effects are temporary or if adjustments to your treatment plan are needed.
