Can patients with a tuberculosis history take Tremfya (guselkumab)?
Tremfya (guselkumab) is a biologic that helps control immune-driven inflammation, and like other agents that affect immune pathways, it can raise the risk of infections. Because of that, clinicians generally screen for tuberculosis (TB) before starting treatment and may treat latent TB first if it’s present.
What TB screening is typically done before starting Tremfya?
Before prescribing Tremfya, patients are usually evaluated for:
- Past or current TB infection history
- Latent TB (often detected with skin or blood tests)
- Symptoms that could suggest active TB
This screening matters because blocking immune signaling can allow TB to become active in people with latent infection.
What happens if someone has latent TB versus active TB?
- Active TB: Patients should not start Tremfya until TB is evaluated and treated. Active infection needs medical treatment first.
- Latent TB (history without active disease): Treatment of latent TB is typically recommended before starting guselkumab, to reduce the chance of reactivation.
Why does Tremfya pose TB concerns?
TB control depends heavily on the immune system. Therapies that alter immune signaling can reduce the body’s ability to keep TB contained, increasing the risk that dormant TB becomes active.
What should patients discuss with their clinician?
Patients with any TB history should ask their prescriber:
- Whether they need a TB test now (even if they had tests years ago)
- Whether latent TB treatment is needed before starting Tremfya
- How their TB history is documented (type of TB, treatment received, and dates)
- What symptoms should prompt urgent evaluation while on treatment (for example, persistent cough, fever, night sweats, weight loss)
If you share whether the TB history was latent TB or active TB (and whether it was treated), I can tailor the guidance more closely to the typical clinical approach.

I don’t have the Tremfya prescribing information text in the provided materials, so I can’t quote specific “TB contraindication” language or timing requirements. If you want, paste the relevant section from the Tremfya label (or tell me your country/label version), and I’ll interpret it for TB history specifically.
