No compromises

Searching online for the best nail fungus treatment?

Let’s face it: over-the-counter fungal products and home remedies don’t really work for toenail and fingernail fungus. And prescription oral medications have downsides - from blood tests and rare side effects, to giving up coffee and alcohol.

Our Caratin Rx topical prescription combines 3 powerful, prescription medications into 1 easy-to-apply formula that provides results. Available online only at Caratin Rx.

Real results from caratin RX customers

Tanvee M.

Age 41.

"I’ve had toe nail fungus for years. Definitely got it from the nail salon. I started using the toenail fungus medication on my big toe and am blown away by my progress. The Caratin doctor said to give toes about 12+ months, but I’m only on month 4 and am seeing serious results already. I refuse to take oral medications because I am wary of side effects so the topical is perfect for me to be able to still treat the fungus. And for the price and convenience you really can’t beat what Caratin has to offer!

Age 49.

“For years I had gross toenails. I skipped beach trips, pool parties, and really anything requiring bare feet.  I’ve tried lots of over-the-counter products to no success.  I’ve been using Caratin every night consistently for months. Thank you Caratin for making this remedy for toenail fungus.”

Tom F.

Age 37

“I took up running during the pandemic and love it - except for what it did to my big toe. Apparently, it’s common for runners to get toenail fungus because we are tough on our feet. I heard about caratin from my neighbor who had a funky toenail. I finished month 9 of the treatment and it has cured my toenail fungus.”

Alice P.

Age 32

“I'm embarrassed to admit, but I got athlete's foot which then turned into toenail fungus. I blame it on the hours spent in the pool and locker room showers. I tried it all - stuff from the drug store and the expensive prescriptions. Nothing worked like Caratin Rx's formula and I'm happy to report my toes are looking much healthier.”

toeNail and fingernail Fungus Affects
15% of the U.S. Population Today

That’s approximately 50 million Americans. Although everyone can get fingernail and toenail fungus, there is a higher incidence in certain populations such as athletes, in particular swimmers and runners, hikers, cyclists, and marathoners. The increase also happens as we get older, and in people with pre-existing medical conditions like diabetes, poor circulation, or prior fingernail and toenail trauma.
