Weight Loss Drugs

Weight loss medications may be exposed as an easy option to lose weight. But you should consider other methods before using weight loss medicine. The best way to lose weight is the natural way - through diet and exercise. However, some people struggle to lose weight. They did all the right things, but they didn't lose weight.

If you are one of these people, then you may want to consider weight loss medications to help you achieve weight loss clinically. Weight loss medicines are not intended for use by Jacks and Jills who only want to lose a few pounds for cosmetic reasons. You can benefit from weight loss medication if you are obese, and obesity can cause health problems.

Weight loss medications cannot replace the need for changes in your eating habits or activity levels.

Practitioners may recommend weight loss medications to different classes including:


  1. Patients with a body mass index (BMI) of 30 or more,

  2. Overweight patients with a BMI of 27 or more who do not have "good" HDL cholesterol have too much "bad" LDL cholesterol, risk for type 2 diabetes, have high blood pressure or have sleep apnea

  3. People who have tried other methods of weight loss, and failed

Common medicines are available in the market

Some of the most commonly prescribed medications are listed below. This list is not complete. The first two are available in the NHS, if you meet their criteria.



  1. Sibutramine (Meridia (US) / Reductil (UK)). This drug changes your brain chemistry, making you feel faster. The usual dose is 10 milligrams (mg) once a day. Possible side effects include increased blood pressure, headache, dry mouth, constipation and insomnia.


  2. Orlistat (Xenical). Prevents the absorption of fat in your gut. The usual dose is 120 mg three times a day. Possible side effects include frequent oily bowel movements, diarrhea, bloating and abdominal pain.


  3. Rimonabant (Acomplia). Works by blocking the endocannabinoid system in the brain that controls hunger. It suppresses hunger and desire. You take 1 pill a day. Possible side effects include dizziness, nausea, anxiety, diarrhea and insomnia.


  4. During sibutramine testing or orlistat users typically achieve 3-4 percent weight loss a year. Rimonabant users typically reach 5-10%, with almost 40% gaining 10% weight. Rimonabant is not expected to be in the NHS over the next two years due to its cost (£ 55 per patient per month).

    Weaknesses to weight loss drugs

    Once you start taking weight loss medicine, you may need to take it forever. When you stop drug treatment, however, much or all of the lost weight usually returns, unless you change your lifestyle.

    The dilemma of taking drugs forever is that the most common weight loss medication is so new that the long-term effects are unknown.
