The Dangers of Weight Loss Drugs

There are many drugs on the market used for other ailments that can also activate or accelerate weight loss. However, taking the step to use such a drug for its unintended purpose is a significant consideration to say the least. Here are some of the most common drugs used for weight loss, their dangers, and our clinical recommendations.


Current evidence shows Saxenda does not seem to be effective for long term weight loss use. Saxenda has a long list of potential side effects including cancerous thyroid tumors, kidney failure and depression. Saxenda is not a quick fix solution to weight loss and needs to be used alongside a reduced calorie intake and increased physical activity. Please click here to find out more.


Ozempic is currently only subsidised under the Pharmaceutical Benefits Scheme (PBS) for uncontrolled diabetes and not weight loss in Australia. Ozempic has a list of potentially serious side effects including potential cancerous thyroid tumours, pancreatitis, and diabetic retinopathy. Ozempic is not a quick fix solution to weight loss but can produce clinically significant weight loss when combined with a reduced calorie intake and increased physical activity.

The HCG Diet

The current popularity of the HCG diet is based around claims that it boosts metabolism and helps lose large amounts of fat without feeling hungry. So, what is the evidence around using HCG for weight-loss? There is no scientific evidence that HCG hormone administration on its own causes weight-loss. Studies show the weight loss occurring on this plan results only from the restricted calorie intake that accompanies it. In Australia, the use of HCG has not been approved by the Therapeutic Goods Association (TGA) as safe or effective for weight loss. Please click here for more information.


Duromine is a prescription weight loss drug used as a short-term adjunct to suppress appetite as part of a medically monitored weight regime. Duromine’s active ingredient is phentermine which is chemically similar to the stimulant amphetamine. Phentermine is one of the most popular and well-known weight loss drugs in the world. It works by directly affecting the area of the brain that controls your appetite making you feel less hungry, which can lead to weight loss. Please click here for more information.


Off-label use of Dexedrine as a weight loss medication is not recommended by major drug regulatory bodies. Current evidence shows Dexedrine provides no long term support for sustained weight loss and cannot be used long term. Dexedrine has a long list of potential side effects including serious heart problems and self harm. Please click here for more information.
