Benlysta

Patients start Benlysta by receiving an infusion on week 0, then week 2, and then every 4 weeks.

Each infusion takes about 60 minutes.

Although some patients can feel better soon after receiving the medication, in others it can take longer. For some patients, it can take up to 3 or 4 months to start feeling the effects of Benlysta.

Benlysta can make it a bit harder for people to fight off infections.

People taking this medicine should call their doctor they have a fever, think they have an infection, or have been prescribed antibiotics to treat an infection.

It is important for patients to coordinate with their doctor to stop treatment before any surgery. Benlysta can be re-started once things have healed and there’s no sign of infection.

Patients should discuss all vaccinations with their doctor because some are not advisable to get while taking this medication.

Some people with lupus have too much protein called B-lympocyte stimulator or BLyS (sometimes pronounced as “Bliss”). It might also be called B-cell activating factor or BAFF.

BLyS can act sort of like a switch that “turns on” special immune system cells: a type of white blood cell called the B-cell (B-lymphocyte).

In lupus patients, B-cells can get confused and attack the body instead of only attacking foreign invaders like the bad germs that make people sick. Benlysta is a biologic medicine that blocks the activity of BLyS.

In blocking BLys, Benlysta suppresses the body’s immune system. Though this suppression can make it slightly harder for patients to fight off infections, it also helps to stabilize an overactive immune system and can help improve symptoms in people with lupus.

Benlysta (belimumab) makes it slightly harder for patients to fight off infections.

Patients should advise their doctor if they develop a fever, think they might have an infection, or are given antibiotics to treat an infection.

Some of Benlysta’s other potential side-effects include:
