Still deciding?
How quickly will I see results?
Everyone responds differently to treatment, but many people notice changes in their appetite within the first few weeks. You may feel less hungry and experience fewer food cravings as your body adjusts to the medication.
Weight loss tends to happen gradually and is usually greatest when treatment is combined with healthy eating habits and regular physical activity. Many people begin to see meaningful weight loss within the first few months of treatment.
In a clinical trial, participants lost an average of 17% of their starting body weight over 64 weeks.
How effective is the pill?
Clinical studies have shown that this treatment can support significant weight loss when combined with diet and lifestyle changes.
In one clinical trial, participants lost an average of 17% of their starting body weight after 64 weeks of treatment.
Individual results vary and depend on factors such as your starting weight, how consistently you take the medication, and any diet and lifestyle changes you make alongside treatment. Taking your medication as prescribed can help you achieve the best possible results.
How do I take the pill?
Take 1 pill once a day on an empty stomach, after fasting for at least 8 hours, with a small amount of water.
After taking the pill, wait at least 30 minutes before eating, drinking anything other than water, or taking any other oral medications.
To get the best results from treatment, try to take your pill at the same time each day and follow your prescribed dosing schedule.
Can I switch from another weight loss treatment to this one?
If you're currently using another weight loss treatment, you may be able to switch. You can start a consultation with our doctors, who will advise you on your treatment options, the right timing and the most appropriate dose for any changes to your current treatment.
