How Does Lunesta Work?

Having reviewed the signs of insomnia and the way to get a proper symptoms management plan, let’s learn more about does Lunesta work. Lunesta is not an opioid and belongs to the class of drugs known as a sedative-hypnotics category that bring restful reactions. The exact Eszopiclone mechanism of action is still unknown. Experts believe that Lunesta is one of the agonists as it interacts with GABA receptors — the natural brain chemicals called ‘gamma-aminobutyric acid’. GABA is responsible for the sleep cycle as it inhibits the excitatory processes in the brain.

What Does Lunesta Do to the Brain?

It is quite an unusual situation that according to the latest data and updated content of scientific references on such topics, there is no totally complete understanding of the processes led by this medication. There is no confusion either: it is believed that Lunesta binds to the benzodiazepine receptors in the brain and brings calm to the mind (just like relaxants work on achieving decreased muscle tension), which in turn helps a person to sleep.

Lunesta is not a drug of choice for consumers who can get a typical night’s sleep of not less than 7 to 8 hours or close to that period. It is only prescribed by mental health experts who have gone through proper certification and authorization, and patients are advised to take it right before bedtime and not sooner than going to bed. It is also considered that Lunesta is not recommended for infants and children; instead, it is a drug for adults, elderly patients, veterans and only under the strict supervision of professionals certified in the area of mental health.

Is Lunesta a Controlled Substance?

Yes. Many serious adverse effects and abnormal conditions are associated with Lunesta, making it a federally controlled substance, so that not everyone can access it. People taking Lunesta may unconsciously get out of bed and do things they wouldn’t remember later after waking up. This includes acting like fully awake people, such as doing the following things from the list:

  • Sleep driving (driving a vehicle unconsciously)
  • Sleepwalking
  • Talking on the phone
  • Getting intimate
  • Eating food
  • Cooking

Apart from the issues mentioned above, Lunesta goes under strict regulations as it can cause addiction and drug dependence. It is not safe for everyone as it is highly potential to develop substance abuse that can be fatal, and patients who experience such a condition need to get addiction help or, in severe cases, receive assistance in an addiction treatment center or a similar site. Patients in such a special facility get help in quitting the medications, having detox, suicide prevention, dealing with the withdrawal symptoms and maintenance of the normal state, like aggression. In a recovery center, people can also treat the impairment (if any) of abuse or overdose.

What If Lunesta Doesn’t Work?

If you wonder how long does it take for Lunesta to work, the answer to such questions is in the fact that it is a quick-acting medication. It can reach the peak concentration level in a duration of 45 minutes to a bit longer than an hour, on average, and a half-life is up to 48 hours. Such a rapid increase ensures falling asleep quickly and having a deep sleep for 7-8 hours. According to placebo-controlled clinical trials, Lunesta proved to be effective.

The good news is that if you don’t see the desired effect that quickly, it should not mean you must switch from Lunestra to other meds. First, consult with a doctor to know if you should change the dosage. Since 1mg Lunesta or Eszopiclone 1mg is an initial dose in the majority of cases, you can be guided to taking 2 Lunesta or a Lunesta 3 mg tablet before going to bed. Still, the specialist will check your health response to offer extra mental or physical care if Lunesta 2 mg side effects occur and their onset leads to worsening your state.

In the case the dose change doesnt help, your medication can be replaced with a common Lunesta alternative — Ambien that conducts similar processes and has a comparable effect. The other three common options taken by people with insomnia include Sonata, Zolpidem, and Zaleplon.
