Raw skin on FIL's bottom. Any suggestions?

Do what you can to help him keep clean, get him some baby wipes if you are sure he will remember not to flush them and make certain he is bathing/showering periodically. Any of the creams used for infant diaper rash will be soothing and preventative.

kdcm1011,
I'm sorry your'e Father in Law is having such a rough time.
What worked the best for my Mother on her raw hiney,was Medi honey put on the wound and then a Dermagram patch put on top that,covered by a piece of gauze with adhesive tape to hold it,kept on overnight each night until the wounds were healed. It took some time and efforts,but they finally healed on Mother.
Good luck finding something that works for you all.Take good care,Lu

He needs to be seen by his Dr,not rule out any fungal or bacterial infection and he may well need continuous multi weekly Dr's visits, if the skin break down is really bad, or deep. Skin infections on the buttocks can become extremely serious, really fast, and if bad enough, the patient can become Septic! Don't wait, get him into see his Dr, then go with what He recommends should be used on the skin irritation, or whatever it might be.

Hubby is incontinent both ways and also on diuretics, so it seems like he’s constantly wet. He’s also bedbound and can get to the toilet. I’ve tried many barrier creams, most of the ones mentioned here. He has an open sore rash on his back that looks like blisters from urine. What I found works the best is plain old cornstarch. Used with diaper rash cream. It’s kind of messy to wash off, and I don’t scrub the irritated skin, but it works.

Why don’t you tell his doctor? Even if you do not have medical poa, you can let the doctor know your concerns.

This problem really needs addressed before it becomes infected and the doctors really need to become involved when he lands in the ER if it gets that bad, which can easily happen. He might also land under guardianship if he can't take care of himself. Just warn him about the freedom he'll lose if he falls under guardianship

An elder's skin thins as they age. I don't advise a cream because it will be more inclined to wipe right off. I recommend an ointment as it's more inclined to stay on the skin. It's critical that the skin, which is the largest organ on the body, remain infection free.

Make sure what you use doesn't burn. Try it on yourself first. There skin is so tender.

True that you will get many answers to this problem but I have to tell you that the one suggestion that worked on my loved one was A&D ointment. I thought it was a miracle!

He needs a barrier cream. Dietary needs for healing is increasing the protein in his diet plus keep his fluids up.
