User Reviews for undecylenic acid topical

Worked great for toenail fungus …took 3-4 weeks but worth it

Used Thorne SF722 which is an oral supplement. Took rash away in 2 servings. Beyond helpful.

I had toenail fungus and athlete's foot for almost a year. I used tolnaftate and clotrimazole for months and they didn't work. Undecylenic acid has been the only thing that worked. It can cause skin sensitivity and it has a funky smell, but it definitely worked for me.

Comes in different concentrations and with different carriers/forms. If in liquid form (alcohol carrier) will sting sensitive skin and really hurt if skin is cracked. Other forms (e.g. creams, powders) will not hurt. Works for athletes foot, but some athletes foot is resistive, so you have to use a different medicine. That is true of most of the different medicines on the market; you just have to try different ones to see which works on your fungus. 25% concentration in alcohol works on nail fungus it can get to, but it can't get way under the nail, so it won't completely kill most nail fungus.Read More Read Less

I tried lamicil at for ringworm on the back of my legs for over 6 weeks, then I tried Lamicil 250 mg pills for 28 days, still did not kill it. I tried undecylenic acid am Nd in 1 week it killed the red circles. Amazing. Highly recommend it.

Was recommended this product by a pharmacist for a toe nail fungus and by the second use, my toe became red and looked like it had a blister on it. I quit using it immediately and my skin became black and turned into a sore where in my toe nail eventually came completely off. I used the liquid version of this medication and would highly recommend using something else for any nail fungal infections.

This treats Toe Nail/foot fungus very well especially for the price. It is 1/3 the cost of what a Foot Dr. sells you for $45-1% Tolnaftate It has no ordor and is pleasant to use

I have used this acid twice for toe nail fungus as directed. Both times I had severe asthma attacks requiring doctor visits. Be careful using this if you have asthme.

i had very itchy sores between some of my toes. I scratched them until they were raw. I had some 'No more fungus spray' by sally hansen. I put this on and it burned for a few seconds,but it really helped within a couple of applications it was nearly healed.I quit using it and the itchy returned, so I used it again a few more times and it went completely away. worked like a charm.

used for fugus of fingernail.no relief

My DPM prescribed it for a fungul nail infection.
