Kirkland Sleep Aid side effects
Kirkland Sleep Aid is an over-the-counter medication that helps people fall asleep. The active ingredient in Kirkland Sleep Aid is doxylamine succinate, an antihistamine that treats insomnia by helping people fall asleep, stay asleep, and get enough restful sleep. Doxylamine is also the active ingredient in other sleep aids, such as Unisom SleepTabs and ZzzQuil.
While some customers report that Kirkland Sleep Aid works well, others mention that it only works intermittently or not at all. Some customers also report that it works better than prescription alternatives like mitrazepine and ambien, and that it helps them fall asleep faster without leaving them drowsy or groggy in the morning. The medication is also noted to be non-habit-forming, a good value, and easy to swallow, although the taste receives mixed reactions.
However, it is important to note that doxylamine may cause side effects such as daytime drowsiness, dizziness, dry mouth, dry eyes, and blurred vision. Alcohol may also interfere with the effects of doxylamine, so it is recommended to avoid alcoholic drinks while taking this medication. If you experience any side effects, it is important to report them to your healthcare provider as soon as possible.
It is always recommended to consult with a qualified healthcare professional before taking any new medication, including over-the-counter sleep aids like Kirkland Sleep Aid.
