- For Tremfya (guselkumab) infusions through the vein: Plan ahead for some time at the medical center or clinic for your infusion. The infusion itself lasts at least 1 hour and you might have paperwork to fill out. Bring something to do, like a book to read, to pass the time.

Risks and warnings for Tremfya (guselkumab)
Tremfya (guselkumab) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Serious allergic reactions
Some people have had serious allergic reactions after using Tremfya (guselkumab). This can sometimes include life-threatening anaphylaxis. Get medical help right away if you have an allergic reaction to the medication. Look out for trouble breathing, swelling in your face or mouth, skin rash, hives, or itching.
Risk of infections
- Risk factors: Active, long-term, or frequent infection | Conditions that can raise your risk of infection | Taking other medications that can weaken your immune system
Tremfya (guselkumab) can affect your immune system and raise your risk of infections. This can include a wide range of bacterial, viral, or fungal infections. It can also include tuberculosis (TB). Serious infections are possible but usually aren't common.
Before starting Tremfya (guselkumab), tell your prescriber about your full medical history and any long-term infections you've had. This is especially important if you've had TB. Regardless, you'll get a TB test before treatment to check for this infection. If you have or had TB in the past, you'll need to take antibiotics to treat it or keep it from coming back. You shouldn't start Tremfya (guselkumab) until any active infections go away.
Be sure to wash your hands often with soap and warm water. And avoid close contact with those who are sick. Call your care team if you have any signs of an infection. Watch for fever, trouble breathing, a cough that won't go away, night sweats, or confusion. You might need to stop taking Tremfya (guselkumab) until you get better.
Liver damage
- Risk factors: Liver problems
Some people had higher liver enzyme levels on their blood tests while taking Tremfya (guselkumab). This can be a sign of liver damage. Most cases were mild or moderate.
But one person with Crohn's disease had serious liver damage after taking higher-than-recommended doses of Tremfya (guselkumab). If you have Crohn's disease or ulcerative colitis, your prescriber will check how your liver is doing. They'll check before you start Tremfya (guselkumab), during at least 4 months of treatment, and every so often after that.
To be safe, watch for symptoms of liver damage. This includes belly pain, low appetite, tiredness, and yellow skin or eyes. Tell your care team right away if you notice any of these. If your tests or symptoms show liver damage, your prescriber might talk to you about other treatment options.
Interaction with vaccines
Before starting Tremfya (guselkumab), talk to your primary care provider about the vaccines you need. They'll help make sure you're up to date. If you need any vaccines while taking this medication, ask your prescriber or pharmacist if they're safe for you.
We don't fully know how Tremfya (guselkumab) affects vaccines. Since the medication affects the immune system, some vaccines might not work as well. You also might be at risk of infection from live vaccines, like MMR (measles, mumps, and rubella vaccine) and Varivax (varicella vaccine). It's best to avoid getting any live vaccines while taking this medication.
