An Entyvio (vedolizumab) infusion takes about 30 minutes once the IV drip starts. But the total time you’ll spend at the infusion center is longer, typically 60 to 90 minutes when you factor in check-in, preparation, and a short observation period afterward.
The 30-Minute Infusion Itself
The actual medication delivery is straightforward. A nurse places an IV line and runs the Entyvio solution over approximately 30 minutes. Each dose is 300 mg diluted in a bag of saline. You’ll sit in a chair or recliner, and most people read, watch something on their phone, or just relax during this part.
What Happens Before the Drip Starts
Before the infusion begins, the nursing staff needs to prepare the medication and get you settled, which adds time to your visit. The drug itself comes as a powder that must be mixed with liquid and allowed to dissolve, a process that takes 20 to 30 minutes. Most infusion centers handle this while you’re checking in, so you may not notice the wait.
Some centers also administer pre-medications about 30 minutes before the infusion. These can include an antihistamine like diphenhydramine (Benadryl) or acetaminophen to reduce the chance of an infusion reaction. Not every patient receives pre-meds, and practices vary by clinic and by your doctor’s preference. If your center does give them, expect that to add roughly 15 to 30 minutes to your total visit.
Observation After the Infusion
Once the IV bag is empty, the staff will monitor you briefly before you leave. Infusion reactions, though uncommon, can occur during or shortly after the drip finishes. Most centers keep you for at least 15 to 30 minutes of observation. If you’ve had several uneventful infusions, your center may shorten this window over time.
Total Time to Plan For
Adding everything together, here’s a realistic breakdown of a typical visit:
- Check-in and vitals: 5 to 15 minutes
- Pre-medications (if given): 15 to 30 minutes
- The infusion: about 30 minutes
- Post-infusion observation: 15 to 30 minutes
For most people, that means roughly 1 to 2 hours at the infusion center. Your first visit may run a bit longer as the staff establishes your baseline and monitors you more carefully. Later visits tend to go faster once you and your care team have a routine.
How Often You’ll Go Back
Entyvio follows a loading schedule during the first several weeks, then shifts to a less frequent maintenance rhythm. You’ll receive your first three infusions at weeks 0, 2, and 6. After that, you move to one infusion every 8 weeks. So after the initial ramp-up, you’re visiting the infusion center roughly six or seven times a year.
The Subcutaneous Option
If the time commitment of regular infusion visits is a concern, there’s a self-injectable version of Entyvio you can use at home. After completing at least two IV infusions, some patients switch to a subcutaneous injection given every two weeks with a prefilled pen. The injection itself takes only seconds.
The subcutaneous dose (108 mg every two weeks) is designed to maintain similar drug levels in your blood as the standard IV dose (300 mg every eight weeks). The tradeoff is more frequent dosing, but you skip the infusion center entirely. Some people also experience mild skin reactions at the injection site, which is less of a concern with IV infusions. Your gastroenterologist can help you decide which format fits your life better.
