The Origin

ORIGINALLY FORMULATED FOR THE BOSTON RED SOX

The Red Sox training staff needed pain relief their players could rub on mid-game: nothing swallowed, no GI issues, fast enough to work between innings.

So our compounding pharmacy built them one: a ketorolac gel that absorbs in seconds and works right where you put it.

That exact formula is KETRO RX: PAIN GEL. Same active. Same strength. Compounded for you at an FDA-registered US pharmacy.

Physician Perspective

Dr. Alexander J. Acosta, MD, licensed primary care physician
“Many patients don’t always know there are topical options for localized pain and tension. That’s why I see real value in KETRO: it lets patients apply the cream directly to areas like the neck, shoulders, lower back, knees, or overworked muscles.”
Dr. Alexander J. Acosta, MDPrimary Care Physician · Emergency & General Medicine

What this is

This isn't drugstore cream.

Not menthol. Not tiger balm. Not a scented lotion pretending to be medicine. This is 0.5% prescription Ketorolac, the formula the Boston Red Sox has used for years. Compounded specifically for you, and strong enough to need a doctor's sign-off.

It doesn't warm your skin and hope. It goes after the pain.

What Customers Are Saying

TMJ / Jaw Pain

Finally off the ibuprofen

“I was popping 4 Advil a day for my jaw and my stomach couldn't handle it anymore. My dentist told me to try a prescription topical NSAID. Honestly can't believe how well this works. I barely touch the ibuprofen now.”
Kelsey Mercer •Verified Buyer
Ketro RX Pain Gel
Post-Workout Recovery

I stopped waking up with cramps

“Tried oral magnesium for months. Did nothing for the tightness. Started putting the magnesium cream on my legs before bed and the cramps just stopped. I actually sleep through the night now.”
Dallas Ryan •Verified Buyer
Ketro CALM Cream
Fibromyalgia / Chronic Pain

I stopped dreading flare days

“I've tried every fibromyalgia pill they've thrown at me. The prescription pain gel goes right on my shoulders during a flare, and the magnesium cream before bed finally lets me sleep. No brain fog. No stomach problems.”

THE SCIENCE

PRESCRIPTION-STRENGTH MEDICATION, EXACTLY WHERE THE PAIN IS

Pills flood your entire system to reach one spot. Topicals don't. Ketro absorbs through skin and works at the site of pain. Never through your gut, never through your liver, never anywhere it doesn't need to be.

An ibuprofen for a sprained ankle is one thing. The same dose, every day for fifteen years, is something else.

01

The Active

0.5% ketorolac tromethamine. A prescription NSAID clinically shown to outperform ibuprofen and naproxen.

02

The Delivery

A transdermal carrier engineered to cross the skin barrier and reach the inflamed tissue locally.

03

The Proof

Originally formulated for the Boston Red Sox training staff. Now prescription-available at home.

Common Questions
Do I need a prescription?

Yes, but it's handled for you. When you order, you'll complete a short online health questionnaire. A licensed provider reviews it and issues your prescription. The entire process happens online. No office visit, no separate appointment.

Is the doctor consultation free?

Yes. The provider review is included in your order. Never a separate charge.

What if the provider says no?

If your provider determines this isn't right for you, you pay nothing. Full refund, no questions asked.

How is this different from ibuprofen?

Ibuprofen is an oral NSAID that passes through your entire digestive system. Ketro RX is applied directly to the site of pain. Same class of medication, targeted delivery, no GI side effects.

How is this different from Icy Hot or Tiger Balm?

Icy Hot and Tiger Balm are menthol rubs. They make your skin tingle so you notice the pain less, and when the tingle fades, the pain is right where you left it. Nothing was treated. Ketro RX is a prescription NSAID. It goes after the inflammation itself, right where you apply it.

Is Ketro RX stronger than OTC Voltaren?

Much, much stronger. That's the point. OTC Voltaren is 1% diclofenac, the strength allowed on a drugstore shelf. Ketro RX is ketorolac, an NSAID in the same class that's strong enough to require a prescription. Same idea, different league.

How long does one jar last?

It's a big jar. 100mL of prescription cream, and a small amount goes a long way. With regular use (a thin layer, 3-4 times daily as needed), one jar typically lasts up to 6 months.

What's the subscription and can I cancel?

Subscribe & Save starts at $110/mo on the 90-day plan (our best value) or $130/mo on the monthly plan. Cancel, pause, or adjust frequency anytime. No commitments.

Where is RX compounded?

Compounded per order by Precision Compounding Pharmacy, an FDA-registered, licensed US compounding facility. Every batch is made to order. Your gel is compounded specifically for you. Never mass-produced, never sitting on a shelf.
