Bleeding risk with Serrapeptase plus aspirin: personal query

Posted by casey613 in Safety & Side Effects - 5 points, 11 comments.

After my arthroscopic knee repair last year I started taking Serrapeptase 120,000 SPU daily on an empty stomach because I read it helped with post‑surgical inflammation and swelling, and I was on low‑dose aspirin for platelet inhibition. Amigos in the forum mentioned a potential bleeding risk but I never tested it seriously until I noticed that the incision site bled a bit longer after each dressing change and I developed a bruise that took more than a week to fade, which was unusual compared to previous surgeries. I also got a mild rash on my forearms after a few weeks of Serrapeptase, and sometimes a mild nausea if I took it with food.

My question is: how critical is the bleeding risk really when using Serrapeptase with aspirin or other antiplatelet agents? Should I check coagulation panels like PT/INR or aPTT before starting, and is there a safe duration for the combination? I’m curious girls, lads, and folks who’ve tried this combo, what did you observe, and did you monitor any bloodwork to stay safe?

  • greg208: Not gonna lie it's a bit of a minefield. I’ve never mixed serrapeptase with aspirin, but I do know aspirin can tweak clotting a touch and serrapeptase might add to that effect. I’d comply with a quick PT/INR check before starting, and keep an eye on any bruising or unexpected bleeding. In my own case, I only had a mild rash and a little tummy upset – nothing dramatic. Have any of you noticed real bleeding changes? Did you do any blood work or just monitor the wound?
  • nof1_nerdy: I’ve been in that spot too. I tried a low dose of Serrapeptase with my regular low‑dose aspirin after a minor procedure. I had a small, longer‑lasting bruise and some mild gastrointestinal upset, but when I sent my blood out for personalizada PT/INR it was within normal limits. I kept a close eye on the wound, and it didn’t bleed excessively. Still, checking the coagulation profile before starting is a good idea.
  • runner_aaron: I tried the combo too. The knee stayed a bit soggy after each dressing change for a couple of days. No major haemorrhage, but the bruise took longer to fade than the last repair. I didn’t do PT/INR – just watched the scar. Anyone else ran labs?
  • greg208: Not gonna lie, I’ve dabbled with serrapeptase on top of low‑dose aspirin after a hip arthroscopy a couple of years back. I didn’t do any bloodwork at first, just watched the wound – it took longer to stop oozing and I got a nasty bruise that lingered. I later got a GP to do a quick PT/INR and it was fine, which made me feel a bit better. The big point is that serrapeptase can thin the blood a bit, so when you stack it with any antiplatelet you’re tipping the balance. I’d say a simple PT/INR bef
  • sleep_coastal: I can totally relate, anecdotally my first post-op after a shoulder arthroscopy with a low‑dose aspirin stack had a similar bruise that took days to fade. I stopped Serrapeptase after the third week when the oozing slowed. PT/INR is a good check, but don’t forget to watch for subtle swelling too.
  • sleep_coastal: Agreed anecdotally, my own mix of longer oozing and a weird rash made me question the combo. PT/INR helped my friend feel safer, but I’d still watch for skin weirdness too. Maybe a doc check if bruises linger or rash spreads?
  • casey613: I’ll order PT/INR next week as you suggested, hoping to catch any platelet lag early, and I’ll touch a doc in case the bruising lingers past the second week or the rash spreads to the trunk. Did you or your friend notice a swing in INR when you added the Serrapeptase? Also, did the rash ever give you a sign that it was more than a mild irritation?
  • casey613: I stopped Serrapeptase after about three weeks when the oozing slowed, so that matches what you did. I did a quick PT/INR check before starting and it was within normal limits, but I didn’t monitor it again. Have you ever checked your coagulation panels during the period you were on the combo? I wonder if a repeat test would catch any subtle changes you might miss just by watching the wound.
  • casey613: Your experience lines up with mine, longer oozing and a bruise that hung around felt off. Since I didn’t do bloodwork initially, should I still get a PT/INR now? You had normal results but the bruising was bad. Maybe it’s worth checking if the risk lingers even without symptoms?
  • casey613: Thanks runner_aaron, I noticed the same longer bruises and a soggy incision after each dressing change. I actually ran PT/INR and aPTT after a month of Serrapeptase plus low‑dose aspirin and everything was within normal ranges. I’m thinking of tapering off after four weeks. Did you notice any change in bleeding if you stopped one of the agents earlier or added a different anti‑inflammatory?
  • casey613: Thanks for the heads‑up – I’ll definitely do a PT/INR before starting, and I’ll also look at a platelet count and fibrinogen just to be safe. Since you mentioned no excess bleeding, I’m wondering if you kept the serrapeptase for how long? I’m thinking maybe 4 weeks max, but I’d love to hear what worked for you.
  • casey613: Thanks for the heads‑up. I did a quick PT/INR before starting as you suggested, but I didn’t do any further blood work after the first cycle. The bruises and bleeding I saw lasted longer than usual, so I’m thinking of repeating the panel after 4 weeks. Do you think a 4‑week cap is sensible, or would you lean to a longer observation period?
