You’re welcome. I’ve done some more searching on this topic and can’t find any real supporting info comparing Kenalog and Depo Medrol because they are in the same drug class. From my personal experience I had bleeding when I received Kenalog for back injections and a shoulder injection, but NOT when I received Depo medrol for knee injections. I just had one in my knee yesterday and felt better almost instantly. I’m not expecting bleeding because I haven’t had that in the past with Depo, but time will tell. This is what I found from a general google search.
“Kenalog (triamcinolone) and Depo-Medrol (methylprednisolone) are both potent, long-acting corticosteroid injections used to treat inflammation, arthritis, allergies, and skin conditions. While often interchangeable, Depo-Medrol may act faster, whereas Kenalog is frequently used for longer-lasting relief (6–8 weeks) and may have a lower rate of post-injection flare reactions (5% vs 25% for Depo-Medrol).
Key Comparisons and Details
Uses: Both treat rheumatoid arthritis, bursitis, osteoarthritis, skin conditions, and severe allergies.
Duration: Kenalog-40 generally lasts 6–8 weeks, sometimes up to 10 weeks. Depo-Medrol injections are also long-acting.”

I just wish more doctors were more aware of this side effect. It wasn’t until I mentioned to my previous gynecologist, the 2nd time it happened, that I had an injection 2 weeks prior to the bleeding that he told me that it could be a side effect. The first time I went through all the follow up of sonograms, hysteroscopy, and progesterone pills. Second time he at least made the connection. Fast forward a few years, I had a new gynecologist, due to insurance changes, and when I mentioned I had had bleeding following a recent shoulder injection, he put me through the same things all over again, because he didn’t seem to believe me about the side effects of steroid injections. He also told me I should undergo a D&C due to the thickening of my lining. Unfortunately that was the beginning of more problems for me. While I was on the operating table, my heart stopped for about 15 seconds and they had to give use epinephrine to get it started again. Needless to say the procedure was stopped before it even got started. Eventually I ended up with a pacemaker to monitor the lows in my heart rate. I’ve was stable for a year and the Dr was comfortable enough to complete the D&C successfully.

Despite all that, I have told my other doctors about the bleeding side effect from injections that I’ve had, and they look at me surprised. And these are the doctors giving the injections!

Good luck to you, and ask your doctor about Depo Medrol the next time and see if it’s a good fit for your needs. Maybe you won’t have the bleeding side effect. Wouldn’t that be nice?
