TREMFYA is administered by subcutaneous injection. The recommended dosage is 100 mg at week 0, week 4, and every 8 weeks thereafter. TREMFYA may be administered alone or in combination with a conventional disease-modifying antirheumatic drug (cDMARD) (eg, methotrexate).1
The recommended induction dosage of TREMFYA is 200 mg administered by intravenous infusion over at least one hour at week 0, week 4, and week 8.1
The recommended maintenance dosage of TREMFYA is 100 mg administered by subcutaneous injection at week 16 and every 8 weeks thereafter, or 200 mg administered by subcutaneous injection at week 12 and every 4 weeks thereafter.1
Use the lowest effective recommended dosage to maintain therapeutic response.1
The recommended induction dosage of TREMFYA is 200 mg administered by intravenous infusion over at least one hour at Week 0, Week 4, and Week 8, or 400 mg administered by subcutaneous injection (given as two consecutive injections of 200 mg each) at Week 0, Week 4, and Week 8.1
The recommended maintenance dosage of TREMFYA is 100 mg administered by subcutaneous injection at Week 16, and every 8 weeks thereafter, or 200 mg administered by subcutaneous injection at Week 12, and every 4 weeks thereafter.1
Use the lowest effective recommended dosage to maintain therapeutic response.1
Administer TREMFYA subcutaneously. Each prefilled syringe, One-Press injector, or prefilled pen is for one time use in one patient only. Instruct patients to inject the full amount (1 mL or 2 mL), which provides 100 mg or 200 mg of TREMFYA, respectively.1
TREMFYA is intended for use under the guidance and supervision of a healthcare professional. TREMFYA may be administered by a healthcare professional, or a patient/caregiver may inject after proper training on correct subcutaneous injection technique.1
Before injection, remove TREMFYA from the refrigerator and allow to reach room temperature (30 minutes) without removing the needle cap.1
Inject into the front of the thighs, the lower abdomen except for the 2 inches around the navel, or the back of the upper arms (healthcare professional or caregiver only).1
Do not inject TREMFYA into areas where the skin is tender, bruised, red, hard, thick, scaly, or affected by psoriasis.1
The TREMFYA Instructions for Use contains more detailed patient instructions on the preparation and administration of TREMFYA.1
If a dose is missed, administer the dose as soon as possible. Thereafter, resume dosing at the regular scheduled time.1
Inspect TREMFYA visually for particulate matter and discoloration prior to administration. TREMFYA is a clear and colorless to light yellow solution that may contain small translucent particles. Do not use if the liquid contains large particles, is discolored or cloudy. TREMFYA does not contain preservatives; therefore, discard any unused product remaining in the prefilled syringe, One-Press injector, or prefilled pen.1
Advise the patient and/or caregiver to read the FDA-approved patient labeling (Medication Guide and Instructions for Use) before starting TREMFYA therapy, and each time the prescription is renewed, as there may be new information they need to know.1
Instruct patients or caregivers to perform the first self-injection under the supervision and guidance of a qualified healthcare professional for proper training in subcutaneous injection technique, including injection of the full dose.1
Counsel patients and caregivers on the proper technique of needle and syringe disposal. Instruct patients to dispose needles and syringes in a puncture-resistant container. Advise patients and caregivers not to reuse needles or syringes.1
Instruct patients that if they forget to administer a dose of TREMFYA, then they should administer TREMFYA as soon as they remember. Instruct patients to administer the next dose at the regular scheduled time.1
