How is Byfavo given?
Byfavo is given as an infusion into a vein. You will receive this injection in a medical, dental, or surgical setting.

Byfavo can make you very drowsy, dizzy, or light-headed. These effects may last longer in older adults. Use caution to avoid falling or accidental injury after you have received this medicine injection. You may need help getting out of bed for several hours.
After treatment with Byfavo injection, you will be watched to make sure the medication is working and does not cause harmful side effects. Your breathing, blood pressure, oxygen levels, and other vital signs will be watched closely.
What happens if I miss a dose?
Because you will receive Byfavo in a clinical setting, you are not likely to miss a dose.
What happens if I overdose?
Since this medication is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.
What should I avoid after receiving Byfavo?
Do not drink alcohol shortly after receiving Byfavo.
Byfavo injection can cause extreme drowsiness that may last for several hours after you have received the medication. Older adults may feel sleepy for even longer.
