Once prescribed by doctors, appetite suppressants have experienced a fall from grace in the past decade. They are no longer available on prescription, and unregulated ones should be avoided — there are plenty of horror stories of people buying dodgy diet pills online. Here we look into appetite suppressants in more detail — including why they are not a safe way to manage your weight loss. We’ll also give you some safer weight loss alternatives to consider.
Appetite suppressants act on neurotransmitters in the brain. These transmitters are natural chemicals found in nerve cells, which are released from the nerve cells as a neural message is transmitted. Neurotransmitters are then reabsorbed into the nerve cells upon the successful transmission of the message.
Appetite suppressants block two of these neurotransmitters from being reabsorbed into the nerve cell. These are noradrenaline and serotonin. These chemicals are responsible for regulating mood and various other processes. Preventing these chemicals from being reabsorbed, results in more noradrenaline and serotonin acting in the brain. This has the effect of enhancing the feeling of being full post-eating. This allows you to feel satisfied for longer after actually consuming less food.
Appetite suppressants used to be prescribed to people with a body mass index (BMI) of 30 or above, or for those with a BMI of 27 or higher if they have other obesity-related risk factors (type 2 Diabetes and high cholesterol).
Appetite suppressants were taken in the morning with or without food. They were swallowed whole with a drink of water. They had the potential to affect your ability to drive or operate machinery, so people in certain industries had to be wary about taking them.
Whilst taking appetite suppressants, your blood pressure and pulse rate required monitoring every two weeks for the first three months. After this, it still needed to be checked every month for the next three months, followed by every three months thereafter.
Appetite suppressants were not designed to be taken for any longer than a year.
Reductil was a popular appetite suppressant that contained the active ingredient sibutramine hydrochloride monohydrate. In 2010 this medicine was discontinued in the UK. The European Medicines Agency conducted a review that suggested a link between taking Reductil and an increased risk of non-fatal strokes and heart attacks.
These risks outweighed the weight-loss benefits achieved with this medicine. People who were taking Reductil were advised to consult with their doctor for alternative weight loss treatments.
Now that they are no longer available on prescription, you may be considering buying appetite suppressants online...but it’s a risky route to take.
There are many supplements sold as suppressants like Ketone, DNP, Matcha, Acai — some with brand names like “fat buster” and “fat burner” — but none of these are medicines, and there is no proof that they actually work!
There are many unwanted side effects to suppressants, and unregulated suppressants are potentially dangerous.
People who suffer from any of the following should avoid them:
Appetite suppressants SHOULD NOT be used by those:
Appetite suppressants can potentially cause side effects. Medicines and their side effects can affect different people in different ways. The following side effects are known to be associated with appetite suppressants. However, because a side effect is listed here, it does not mean that everyone who takes appetite suppressants will experience all, if any, of these side effects:
Before you start any new treatment, you should always inform your doctor or pharmacist of the medicines you are currently taking, including those bought over-the-counter and any herbal treatments.
Appetite suppressants can interact with other medicines, making them potentially ineffective, even dangerous. They should not be taken at the same time as, or within 2 weeks of any of the following medications:
Appetite suppressants should not be used at the same time as other medicines that increase the serotonin levels in the brain. Doing so may result in a side effect called serotonin syndrome, which can be serious. Medicines that increase the brain’s serotonin levels include:
The following medicines can increase the risk of experiencing the side effects associated with appetite suppressants:
The following medicines can decrease the effectiveness of appetite suppressants:
You should consult your doctor or pharmacist before taking any cough, cold or allergy treatments whilst considering taking appetite suppressants. Some of the ingredients found in these remedies can lead to an increase in heart rate and blood pressure, which should be used with caution when taken in conjunction with a suppressant.
Rather than risk your health with unregulated and potentially harmful appetite suppressants, you can try other weight loss pills that have been proven to be effective and are still prescribed by doctors in the UK.
Orlistat is not a suppressant and works in a completely different way, not impacting the brain or appetite at all. Orlistat actually binds to dietary fat and therefore must only be taken under certain conditions. You must always follow a low fat diet and exercise regime when taking Orlistat.
A weight loss remedy like Orlistat is safe to take as it’s regulated and licensed — just make sure that you talk to your doctor and pharmacist so that they can safely dispense and prescribe Orlistat as a treatment and judge whether it’s suitable for you.
Don’t play around with your health and resort to extreme diets, unsafe diet pills, or appetite suppressants. It’s best to speak to a doctor or pharmacist if you are experiencing difficulties losing weight.
