Frequently asked questions
How many nitroglycerin tablets does it hold?
It holds up to 7 Nitrostat tablets, or about 2 of the slightly larger Lifestar tablets. Exact capacity depends on your brand of nitroglycerin (inner diameter 0.2 inches).
Is the nitroglycerin pill holder waterproof?
Yes. An O-ring seal and milled stainless steel threads keep your tablets dry and protected, even if it is submerged.
Can I carry nitroglycerin outside its original bottle?
Some people keep a few tablets in it for emergencies, but check with your doctor or pharmacist first, because some nitroglycerin is meant to stay in its original glass bottle. If yours is, see our nitroglycerin bottle holder instead.
What is it made of and where is it made?
Solid stainless steel, with a lighter titanium option, machined with a partner in Minnesota, USA, and guaranteed for life.
Carried, trusted, treasured
It went through a pre-wash, wash, and extra rinse cycle and the two pills inside were completely dry and intact. Great product!
