The nitroglycerin pill holder that never leaves your keys.
Machined from solid stainless steel and sealed against water, then built to ride on your keychain — so the one medicine you can't be without is always an arm's reach away, never left in a drawer at home.
“I recently had a heart attack and learned I must carry nitroglycerin everywhere. The first thing I did was buy this tiny quality pill holder for my key ring.”

Choose the pill holder that fits your routine.
Many doctors suggest keeping nitroglycerin in its original bottle — our bottle holders are built for exactly that. Some people prefer to carry a few tablets in the Extra-Small. Choose what works for you and your doctor.
Extra-Small Nitro Pill Holder
Holds a few loose nitroglycerin tablets — the smallest, most discreet way to keep them on your keychain.
Wide Single Chamber Bottle Holder
Holds a standard 25-count nitroglycerin bottle — keep your nitro in its original bottle, right on your keys.
Large Dual Chamber Bottle Holder
Holds the nitroglycerin bottle plus aspirin in the top chamber — everything in one place when it counts.

Your nitro only helps if it's on you.
An emergency doesn't wait until you get home. Clipped to your keys, your nitroglycerin goes where you go — the car, the course, the grocery line, the middle of the night. No drawer, no other bag, no second-guessing where you left it.
Carried, trusted, treasured
After five years of battering, the thing still looks as new as the day I purchased it — and it has never leaked.
The peace of mind knowing that my nitro pills will be in good shape should I ever need them is priceless.
Threaded closure with O-ring seal holds securely. I carry 5 pills but it could handle a couple more.
The threads on lid and case are extra brawny, finished so that no sharp edges exist.
