How to Take Mysimba

Mysimba tablets should be swallowed whole with water and can be taken with, or after food. Never chew, crush or split Mysimba tablets – this can alter the release of the active ingredients into the body.

Follow your doctor’s advice on Mysimba dosage. Your dose will typically be increased over a period of four weeks, by which time you will reach your ‘maintenance dose’. Mysimba dosage is usually increased as follows:

  • Week 1 – one tablet taken in the morning
  • Week 2 – one tablet taken in the morning, and one tablet taken in the evening
  • Week 3 – two tablets taken in the morning, and one tablet taken in the evening
  • Week 4 – two tablets taken in the morning, and two tablets taken in the evening

Once you reach Week 4, you will continue with the Week 4 dosage – this is known as the ‘maintenance dose’; the maximum recommended Mysimba dose. You should always follow your doctor’s instructions for taking Mysimba.

How Long Does Mysimba Take To Work?

If you have not lost at least 5% of your body weight at 16 weeks, your doctor will consider if you should stop taking Mysimba. Note that you can achieve the best results when combining Mysimba with a healthy lifestyle and balanced diet.

Guidance from Orexigen Therapeutics, the company which manufactures Mysimba, advises that after eight weeks of treatment, improvements can be seen. Research conducted with over 4,500 overweight or obese patients shows that Mysimba has a significant effect on weight loss, compared to patients who were given a placebo.
