Kirkland Sleep Aid Ingredients. The active ingredient in Kirkland Sleep Aid is ‘doxylamine succinate’, an antihistamine. It is a substance used to treat allergies but also works to induce sleep and help people stay asleep. In fact, doxylamine works more effectively to help those with insomnia than those suffering from allergies.
Kirkland Sleep Aid Ingredients
There’s a fair amount of chemistry on this page, but don’t worry too much. There is just one ‘active’ ingredient in Kirkland Sleep Aid, doxylamine succinate. The other ingredients, listed below, are not compounds designed to make you sleep, but are some of the standard ‘building blocks’ of any tablet. These ingredients are inactive, that is, they don’t do anything to you.
Each Kirkland Sleep Aid tablet contains 25mg of doxylamine succinate, the ‘active’ ingredient, that is, the ingredient which makes you sleepy.
Doxylamine is an antihistamine, used to relieve symptoms of allergy, hay fever, and the common cold. This medication works by blocking certain natural substances (histamine, acetylcholine) that your body makes. This effect helps to relieve allergy/cold symptoms such as watery eyes, runny nose, and sneezing.
