Many individuals believe that any weight-loss pill must be a fraud. However, there are weight-loss medications that exist - and work. The only catch is that they're not for 'cosmetic’ use, meaning those in good shape or looking to shed a few pounds should not take them.

Who is suitable for weight loss pills?

If you haven't been able to reduce weight through diet and exercise, your doctor may prescribe a weight-loss drug for you if you fit into one of the following categories:

  • You have a body mass index (BMI) greater than 30.
  • You have a BMI greater than 27 and a medical problem that causes obesity.

To ensure you lose weight safely, your doctor will evaluate your health and medical history before selecting a medication for you. Your doctor will then go over the advantages and risks of prescription weight-loss medications with you.

It's vital to remember that weight-loss medications aren't for everyone. If you're trying to get pregnant, are already pregnant, or are breastfeeding, for example, prescription weight-loss medications should not be used.

How much weight can you lose?

Compared with a placebo, prescription weight-loss medicines that have been authorised for long-term usage (more than 12 weeks) result in considerably more weight reduction.

The use of weight loss pills in combination with lifestyle modifications results in greater weight loss than lifestyle changes alone. Those who are severely overweight, for example, may lose anywhere from 3% to 7% of their body weight in the first year.

That may appear to be a minor amount. However, 5% to 10% weight loss over time can result in major health benefits, such as lowering blood pressure, blood sugar levels, and triglyceride levels.

How long should you take weight loss pills for?

How long you'll need to take a weight-loss pill is determined by whether it aids in your weight reduction. If you are starting to lose weight and showing no signs of serious side effects, your doctor may recommend that you continue taking the drug.

If you haven't lost at least 5% of your weight after three to six months, your doctor will most likely change your therapy or switch you to another weight-loss drug.

Important things to know

Common side effects of weight loss pills include nausea, constipation, and diarrhoea. They may go away with time. Severe side effects are uncommon. As a result, it's critical to talk about all treatment choices with your doctor thoroughly.

When people stop taking weight-loss medications, they frequently regain some of the weight they've lost. However, adopting healthy lifestyle choices may assist you to avoid gaining weight.

What weight loss pills are available?

There are three forms of weight loss medication available at Express Pharmacy:

  • Bupropion-naltrexone (Mysimba)
  • Liraglutide (Saxenda)
  • Orlistat (Xenical)

Prescription weight-loss medications work by decreasing hunger and increasing satiety. Some do both. Orlistat is the lone exception, as it works by blocking fat absorption.


Mysimba (Bupropion/Naltrexone) is a combination therapy. Naltrexone is used to cure alcohol and opioid addiction. Bupropion is an antidepressant as well as a smoking cessation medication.

Mysimba can raise blood pressure - due to this, monitoring is required at the start of therapy.


Saxenda (Liraglutide) is also used to treat diabetes. Liraglutide is given by injection, unlike other weight-loss medications.


Xenical (Orlistat) is a prescription drug that may aid in the management of weight loss. Xenical works by stopping your body from absorbing fat from the meals you consume. Xenical can make it easier to lose weight since it reduces the amount of fat absorbed.

To summarise

Weight-loss medications aren't the solution to weight reduction. They might, however, assist you in making the required lifestyle changes to lose weight and improve your health.
