Hi, @evinann
You say your husband's spots bleed? Is there actually blood coming out of them or just under the skin? I had some really large ones at one point but they are not nearly as bad now. I believe the difference for me was that I was on prednisone and no longer am.

My dermatologist prescribed tretinoin cream for me. It helps to strengthen the skin because the cause is generally that our skin gets thinner as we age. Prednisone makes it even more so.
This is a fairly good article about tretinoin. It also mentions side effects. I did not have any but of course I did wear a strong sunscreen when going out.

There is another OTC cream also, Dermend, but I don't know if that is effective or not. Tretinoin did help me. It did not completely rid my arms of the purpura but it did minimize them.
If you do get a prescription for it, be aware that it is not covered by Medicare since it is considered to be cosmetic. If you use the app GoodRx you can often find a much better price than is available without it.
