Brand Names: Tremfya
What is Tremfya?
Tremfya (guselkumab) is a monoclonal antibody that blocks a certain protein in the body that can cause inflammation and other immune responses.
Tremfya is used to treat moderate to severe plaque psoriasis in adults.
Tremfya may also be used for purposes not listed in this medication guide.
Tremfya can weaken (suppress) your immune system, and you may get an infection more easily.
Call your doctor if you have signs of infection such as fever, chills, body aches, weight loss, severe diarrhea, stomach cramps, pain or burning when you urinate, cough (may contain blood or mucus), shortness of breath, or skin sores that look different from psoriasis.
Before taking this medicine
You should not use Tremfya if you are allergic to guselkumab.
Tell your doctor if you have ever had tuberculosis, if anyone in your household has tuberculosis, or if you have recently traveled to an area where tuberculosis is common.
Before you start treatment with Tremfya, your doctor may perform tests to make sure you do not have tuberculosis or other infections.
To make sure Tremfya is safe for you, tell your doctor if you have:
an active or chronic infection;
active tuberculosis infection that is not being treated; or
if you have recently received or are scheduled to receive any vaccine.
Make sure you are current on all vaccines before you start treatment with Tremfya.

Tremfya is injected under the skin. You may be shown how to use injections at home. Do not give yourself this medicine if you do not understand how to use the injection and properly dispose of used needles and syringes.
The first two injections are usually given 4 weeks apart, followed by one injection every 8 weeks. Your doctor will determine how long to treat you with this medicine.

Tremfya should appear clear to light yellow in color. Do not use the medicine if it looks cloudy or has particles in it. Call your pharmacist for new medicine.
