Speed of Action

When taken daily, Mysimba usually takes a few weeks to work. The dosage is gradually increased to get your body adjusted to the active ingredients.

The standard Mysimba absorption time is a few hours. This depends on the size and contents of your last meal, as well as your metabolism.

Mysimba will start to work from the first tablet, but it will take a few weeks before it reaches its full effect. You may notice a gradual change in your appetite during this time.

Treatment Duration of Mysimba

You can take Mysimba for as long as you need it. You will need a 16-week check-up with your doctor, followed by annual check-ups.

The half-life of a medication is how long it takes for half of the dose to leave your system. Mysimba half-life is different for each active ingredient:

• naltrexone - 5 hours
• bupropion - 21 hours

Mysimba will stay effective until your next dose is due and works best when it has had time to build up in your system.

After 16 weeks, your doctor will check if you’ve lost at least 5% of your starting body weight. Your doctor will recommend that you stop Mysimba if you:

• haven’t lost at least 5%
• get intolerable side effects that are not going away
• have high blood pressure

You must stop taking Mysimba if you find out that you’re pregnant.

Long-term Use

Your doctor will monitor your health while taking Mysimba and you can stop the medication at any time, as long as you speak to a healthcare professional first.

Dosage and Factors Affecting Efficacy

It’s not recommended to take Mysimba after the age of 65. If you have a pre-existing health condition or take a certain medication, Mysimba may work differently. Your doctor will discuss this with you when prescribing.

Missing a dose may decrease the effectiveness of Mysimba.

What to Do If You Find the Dose Ineffective

If you find your Mysimba dose is not effective, wait a few weeks after starting treatment. Your doctor will check in after 16 weeks, but you can speak to them sooner if you don’t think Mysimba is working for you.

Conclusion
