Lunesta and Ambien are two of the most commonly prescribed medications that can help to manage insomnia symptoms in a short duration. In the case one cannot take Lunesta similar drugs may be prescribed, such as Ambien.

Currently, in some cases, antidepressants and muscle relaxants can be prescribed to reduce the symptoms of sleep disorders. These medications can effectively treat insomnia if the information sourced from the results of the medical assessment shows that depression or muscle tension cause your condition.

Mechanism of Action

Both Lunesta and Ambien belong to the medicine class “sedative-hypnotics”.

Although they belong to the same class and work similarly, Lunesta (Eszopiclone) and Zolpidem have different ingredients and formulations, which make them different in many aspects, so starting taking them without consulting with a doctor is not allowed.

What Are the Main Differences Between These Medications ?

Both medications are used for the short-term symptoms management of insomnia but vary in form and dosage. The available strengths are as follows:

Lunesta Ambien
  • 1mg, 2 mg, and 3 mg immediate-release tablets
  • Not available in extended-release tablets
  • 5 mg and 10 mg immediate-release oral tablets
  • 6.25 mg and 12.5 mg extended-release tablets (Ambien CR)

Also, Lunesta has a longer half-life which is six hours as compared to Ambien which is 2.5 hours. This means that people taking it will sleep longer. Also, as per common warnings, note that you cannot take an excessive dose of these pills such as 3mg Lunesta vs 10mg Ambien during one day because it can provide medical issues such as difficulty concentrating, worsen driving skills, lead to impaired memory, and more.
