Safe Prescription Diet Pills

Can I Buy Prescription Diet Pills Online?

The Online Clinic is happy to prescribe certain weight loss pills depending on the patient’s individual medical circumstances. These medications are all effective prescription medications but they cannot be taken by everyone so it is important that we have an accurate medical history before we can make a diagnosis and treatment recommendations.

As a regulated clinic, we can prescribe diet pills to help you lose weight. We offer a free, no obligation online consultation to check your suitability. Next day delivery is guaranteed in the UK.

We often get asked which are the best diet pills based on effectiveness and the speed at which they produce results. The short answer is that it is impossible to give a definitive and over-arching answer to this query because the medications work in different ways. Where one weight loss medication may work well for one individual, the same treatment may have a limited impact on another patient.

Studies have shown that using certain prescription diet pills can double the weight loss that you can expect to achieve when compared with diet and exercise alone.

A summary of the effectiveness of each of these medications, taken from the clinical trials, is set out below. A comparative study of each of the different medications has never been undertaken, to our knowledge. The patients who were administered a placebo in the trials were given the same diet and exercise regime to make the results comparable. By looking at the two sets of results, you can see how effective each medication is when compared with diet and exercise alone.


Over a two year period, two groups of patients were given the same low fat diet. One group was administered Orlistat (the active ingredient in Xenical) and one was administered a placebo. By the end of the first 12 weeks of the study, 37% of the Orlistat patients had lost 5% of their body weight compared with only 19% of patients on the placebo. At the end of one year, 20% of Orlistat patients had lost 10% of their body weight compared with only 8% of patients being administered a placebo.

Mysimba was launched in the UK in 2017 and is an appetite suppressant. The percentage of patients using Mysimba in the clinical trials who lost at least 5% of their body weight was more than double that of those on the placebo who lost the same about of weight. Patients who responded well to the medication in the first few months were much more likely to continue the weight loss trajectory.

Saxenda is a daily injection that works as an appetite suppressant. This medication has a high success rate and is one of our most popular weight loss treatments.

In clinical trials, 62% of patients lost at least 5% body weight, compared with 34% of those in the placebo control group. 34% lost at least 10% of body weight compared with 15% on the placebo control group.

New Diet Pills

There are at least two new diet pills that are expected to be examined by European regulators in the next few years – Qsiva and Lorqess.

Both Reductil and Acomplia have had to be withdrawn in recent years so regulators are extremely cautious in the area of weight loss medications, as they are likely to be taken by very large numbers of people; studies that might be done post-licensing are being requested prior to a marketing authorisation being granted.

Further details of the new diet pills being considered by regulators are given on the slimming pills page of this website.

Prescription diet pills are not appropriate for everyone so please complete a consultation form that will be reviewed by one of our doctors.
