Our round up of the best non-prescription Phentermine alternatives

phterminePhentermine has been the most highly prescribed diet drug since its FDA approval in the 1950s for the short term treatment of obesity. Users can expect to lose between 5-10% of their initial body weight after completing a course.

It is a controlled substance which can be habit forming, prone to side effects and ineffective over longer periods of time. As a result phentermine is only prescribed for a maximum of 12 weeks to initiate weight loss where risks to health are significant if reduction isn’t achieved.

Phentermine is available in branded and generic forms, and can also be found combined with other drugs such as topiramate in Qsymia, a diet drug due to be available in late 2012 early 2013.

Non-prescription alternatives to Phentermine

There are a number of commercial Phentermine alternatives now available which promise to deliver similar results as seen with its drug-based version, but do not pose the same associated health risks and side effects.

Phenobestin 37.5 and Phen375 are popular options in this category – both manufactured to strict standards using premium quality compounds. The ingredients in these prescription-free alternatives are typically proven to increase the metabolism, while also suppressing the appetite.

This combination of calorie restriction and increased fat burn (which is the basis of branded Phentermine) can contribute to significant weight loss.

There are a wide variety of other natural weight loss supplements available which can provide an alternative to phentermine. These come in the form of appetite suppressants, fat blockers, fat burners and energy boosters. These can be found in local chemists, supermarkets and health food shops and are available to buy over-the-counter.

Even natural supplements can cause side effects, especially as many contain natural stimulants which can lead to insomnia, raised heart beat and irritability, but generally they are safe and effective to use, even for long term weight loss.


Prescription-only alternatives to Phentermine

There are a number of prescription drugs which are available to overweight patients in addition to Phentermine. The lipase inhibitor Orlistat, sold under the brand name Xenical works by blocking the absorption of fat from foods which are then excreted from the body.

This option is also not without side effects, liver and gastrointestinal problems are common such as frequent, loose bowel motions, and it can affect the body’s ability to absorb nutrients from foods as well as certain medications.

As with phentermine, the suitability of orlistat will be assessed by the medical professional before prescription, as it is unsuitable for people with certain health problems issues including: gall bladder problems, chronic malabsorption, along with certain liver, kidney, thyroid or eating disorders.

Orlistat is also available over the counter at half the strength of Xenical, this is sold as Alli.

Exercise and Healthy Eating as an Alternative to Phentermine

Phentermine itself is designed only to play the first part in weight loss which should be continued through diet and exercise.

For those in the morbidly obese category a sedentary lifestyle and uncontrolled eating means a sudden diet and lifestyle change is too daunting or ineffective, and phentermine creates a much needed kick start to weight reduction.

Phentermine is not to be considered for cosmetic weight loss, especially where diet and exercise provide an easy alternative, or where the risks to health are not significant enough to justify the risk factors associated with this potentially harmful drug. Those who are not deemed to be morbidly obese should consider other options first.
