Renflexis: Uses, Side Effects, Warnings, and Dosing Information

Generic Name: Renflexis (infliximab)

Renflexis Reviews

For Ankylosing Spondylitis "After using Remicade for years I switched to Renflexis because it had better insurance coverage. Renflexis has worked remarkably well for me. The Remicade kept my AS under control but I would get random temporary swelling in my hands and knees which is not happening with Renflexis"


For Crohn's Disease "I started with Remicade/Inflectra in 2019 when my Crohn's disease became super activated in graduate school. Both of those helped. I was switched by my provider to Renflexis this past September due to cost, and my last two infusions were with Renflexis. I have noticed an improvement over Inflectra. Bowel movement frequency has decreased, and the looseness of stools has improved - and I have a very short gut due to two bowel excisions and resections. I'm pretty excited about this improvement. I was worried initially and reassured that it is biosimilar. It may be, but whatever difference Renflexis has, it's working better for me!"


For Rheumatoid Arthritis "I have experienced reduced pain in joints and less inflammation for a year. I realize that changing my diet is also part of maintenance. Serious anti-inflammatory dieting due to being obese. I know that my weight contributes to RA flare-ups. I am constantly tired and it takes some exercise to get going every day. Mostly Yoga since it is hot outside. I receive infusions that are easy to handle."


For Ankylosing Spondylitis "Switched to this because insurance made me. Was supposed to be the same thing but 5 hours after my infusion I had burning in my esophagus and throughout my lungs. The left side of my face went numb and I was extremely dizzy. Then extreme abdominal pain which then turned into me screaming in the bathroom with horrible diarrhea. I was on Remicade for 8 years but that never happened so I do not think they are the same. I am normally pretty sensitive to medication so I was surprised that I handled Remicade so well. I was not expecting such a horrible reaction from something that’s supposed to be the same."


For Ankylosing Spondylitis "Amazing medication! I have been in constant pain with AS for about 12 years. My condition is not classed as 'very advanced' yet, however, it is enough to keep me up at night and leave me very stiff and with limited mobility. Although I was told it could be a few weeks before I would feel better, from the very first infusion - that very day, I started to feel a LOT better. At night, for the first time, I actually slept right through and woke up with no pain or stiffness whatsoever. It has been a week now and I feel as good as ever, and my mobility and range of motion has returned. I have not had to take any additional medication or sleep in an upright position, which has been my go-to for over 5 years. I genuinely couldn't be happier, it has made a positive impact on my life. On a side note, it may be unrelated, but the infusion left me feeling very hungry after the session and gave me the munchies for the rest of the day. However, the next day I was back to normal."


For Crohn's Disease "This medication totally debilitated me. It’s a generic drug that should be taken off the market."


"On this for sarcoidosisAfter nine treatments lymph nodes shrunk enough to open my brachia that the enlarged lymph node pinched off and right upper lobe reinflated."


For Rheumatoid Arthritis "I have been on Renflexis for approximately 1 year. Very few side effects. I am feeling much better since starting this medication."
