Samantha Successfully Treats Keto Rash With Doxycycline

Samantha developed keto rash but didn’t want to stop doing the diet so she opted to go with doxycycline which successfully treated the rash.  She did a wonderful job documenting her experience with photos as you can see.

Here is Samantha:


Around day 9 of keto, I noticed a small rash under my breasts. It wasn’t itchy at first, but it spread VERY quickly and within 3-4 days my chest, neck and some areas of my sides and back were covered in bright red bumps and splotches. It was unbearably itchy and reached a point where it would burn and sting. While I initially thought I’d be able to wait it out, I couldn’t handle it, and it was extremely noticeable. I didn’t want to give up my diet so I saw my doctor who prescribed me a month long course of Doxycycline. A quick note for anyone who doesn’t have insurance- this medicine is really expensive. At Walgreens I was quoted $165, but I luckily was able to buy it at Costco pharmacy for 1/3rd of that price, so you definitely want to call around.

About three days after beginning my doxycycline course (100mg twice a day for thirty days) the rash became less itchy and started taking on a shriveled, withered look. After two weeks, it was pretty much gone and it only itched during showers and sometimes at night. I had been taking the capsules with food to combat the nausea the medication caused, which is not recommended because the medicine doesn’t absorb as well. I started taking it on an empty stomach only and found that caused the rash to go away completely within a week. The doxycycline is the only thing that gave me relief after trying several lotions, creams and natural remedies. It seems to be gone except for a little bit of hyper pigmentation, which appears to be fading. Hope this helps!

    Did you remain on the keto diet and did the rash stay away after your course of antibiotics?
