Alprostadil Injection Bruising: How I Handled It and My Questions

Posted by greg208 in Safety & Side Effects - 1 points, 3 comments.

helpers suggested it for my erectile issues. The first few injections were fine but I started getting a lot of bruising around the site. 2 mL per dose, and I injected in the dorsal side of the penis at a 30‑degree angle, about 1 cm from the head.

Even though it was quick, the bruises appeared after 12–24 hrs and stayed there for a few days. I tried applying cold packs for 10 mins right after injection and cleaning the area twice a day with an alcohol wipe, but the bruises still came. I’m wondering if I should switch to a finer gauge, or maybe rotate the injection site a bit more.

I’ve also read that repeated use can lead to penile fibrosis, so I’m cautious about how many injections a week I do. How have others dealt with spot bruising? Any tips on technique or post‑injection care that might reduce the swelling and give me peace of mind about fibrosis?

  • aspiring_trailrun: I’ve had a few bruises myself with local injections and found a couple of small tweaks that help. First, try a finer gauge, switching from 25 g to 27 g can reduce the needle shock, especially in a thin area. 5‑1 mL is still effective for alpro használ, but it feels less traumatic. Rotate more extensively – aim for at least three distinct spots around the corona rather than a single line. After injection, let a cold pack sit for only 5 min, over‑cooling can worsen bruising. If the bruises linger
  • greg208: 5 mL as you suggested – that should still hit the target but feel gentler. I’ll also spread the sites to three spots around the corona, not just a line. About the cold pack, I’ll keep it to 5 min and try a warm compress next day. How long do you usually wait before rotating sites in your routine?
  • greg208: Not gonna lie, swapping to 27g helped cut the bruises a bit. I use 1.5 ml and spread it over four spots instead of a line. A 3‑minute cold pack does the job; too long just makes it a bigger bruise. I keep it to one or two injections a week and the bruising’s getting less.
