The NHS Insomnia, Anxiety, and Sleeplessness illnesses are treated with zopiclone 7.5mg Tablets. If you're over 18 and have trouble falling asleep, your doctor may recommend zopiclone for you as a legal medicine. Little research has been done on its application and efficiency in adolescents under the age of 18. Even so, if doctors decide it's the best treatment for you, they may provide medicine to you "off-label."
