Your dose of Benlysta will be based on factors such as how much you weigh and how well you tolerate the medication. This drug is given as an intravenous (IV) infusion. It is administered once every two weeks for the first three doses and then once a month. Before each infusion, your healthcare provider will likely give you "premedications" to reduce the risk of infusion reactions.
The dose of Benlysta® (belimumab) your healthcare provider recommends will vary, depending on a number of factors, including:
- Your weight
- How well you tolerate the medication.
As is always the case, do not adjust your dose unless your healthcare provider specifically tells you to do so.
The standard dosage of Benlysta for treating systemic lupus erythematosus is 10 mg per kg (about 4.5 mg per pound) every two weeks for the first three doses, then once a month.
People who experience certain potentially serious Benlysta side effects may need to stop using the medicine. Benlysta should not be restarted if the side effect was severe or life-threatening. Otherwise, the medicine may be restarted at the usual dose once the side effect improves.
Benlysta can cause allergic reactions as well as "infusion reactions," which are similar. Your healthcare provider may give you medications beforehand to help reduce the risk of such reactions.
Some considerations to keep in mind during treatment with Benlysta include the following:
- This medication is given as an intravenous (IV) infusion, which is a slow injection into the vein. It is usually given every two weeks for the first three doses and then once a month.
- The injections are given by a healthcare provider in a healthcare setting.
- Each Benlysta dose will be given slowly over a 60-minute period. You may be given medications beforehand to help reduce the chance of allergic reactions. These "premedications" may add to the total time you will need to receive your dose.
- For Benlysta to work properly, it must be used as prescribed. The medication will not work as well if you miss doses.
- If you are unsure about anything related to dosing with Benlysta, please talk with your healthcare provider, nurse, or pharmacist.
