Living With Obesity; Should I Take Weight-Loss Medicine?

 

We all know that obesity is not healthy. People living with obesity suffer from serious health complications like high blood pressure, cardiovascular diseases, and diabetes. If you have been on a weight loss journey with exercise and eating a healthy diet but cannot lose weight, then it’s time to visit an expert healthcare practitioner who can guide you further. 

 

They might prescribe you anti-obesity medications, such as Wegovy or Phentermine, for weight loss. These drugs are approved by the FDA and help people in their weight loss journey, subsequently reducing the risk of chronic health disease.

Do I Qualify for Weight Loss Drugs?

 

You can only qualify for weight loss drugs if you are unable to lose weight combined with exercise, have a BMI of more than 30 or more than 27, and suffer from some chronic disease related to your weight, such as highest blood pressure and heart disease.

More on Wegovy vs Phentermine

 

Both Wegovy and Phentermine are prescribed for obesity or to people who are obese and suffer from weight-related issues like high blood pressure, high cholesterol, or type two diabetes. Although used for weight loss, Wegovy and Phentermine are different. Brand-name Wegovy was approved in 2021, while Phentermine, a generic drug, was approved in 1959. 

Key Differences Between Wegovy vs Phentermine

 

Yes, both are medications used to help shed extra weight. But they are different in many ways. Let us find out the key differences between Wegovy and Phentermine.

Active Ingredients

 

The main difference between the two is their active ingredients. Phentermine belongs to a class of medications called sympathomimetic amines. These medications promote the release of norepinephrine, a neurotransmitter in the brain that suppresses appetite. Phentermine’s mode of action is similar to amphetamine’s.

 

In contrast, Wegovy consists of semaglutide, a glucagon-like peptide-1 GLP-1 receptor agonist. This receptor agonist mimics a hormone that regulates hunger and appetite and releases insulin. Thus, you feel fuller after eating a little food, helping reduce calorie intake.

Dosage and Drug Forms

 

Wegovy is available in injectable forms, prescribed only once a week. However, the final dosage varies throughout the treatment. A small dosage initially reduces the chances of risks and helps develop tolerance.

 

Phentermine is available as tablets and capsules under the brand names Lomaira and Adipex-p, and another drug called Qsymia, a combination of topiramate, aids in weight loss. The usual dose is one/day.

Conditions Treated by Wegovy vs. Phentermine

 

Wegovy has FDA approval for managing chronic weight management in children > 12 years and for adults suffering from obesity. Wegovy is also helpful in obese adults living with at least one weight-related health condition.

 

In contrast, Phentermine has FDA approval for managing weight in children> over 17 and obese adults. However, Wegovy is approved for long-term weight loss treatment, while Phentermine is only approved for short-term use.

 

 Wegovy vs. Phentermine is part of a treatment plan that includes a reduced-calorie diet, exercise, lifestyle modifications, and proper guidance from healthcare professionals.

 

Do you know that Weogvy has also been approved to reduce the risk of heart-related complications? It helps to reduce the dangers of stroke, heart attacks, and other heart complications, making it an ideal choice for obese people living with heart disease.

How Does Wegovy vs Phentermine Compare for Weight Loss?

 

Wegovy and Phentermine aid in weight loss, but how much weight you shed depends on factors like your baseline weight, overall health conditions, and how your body responds to the drug and lifestyle changes. Nevertheless, the good news is that both show promising results.

 

Many clinical trials are required to determine which is more effective. However, the results show that Wegovy showed better results. One study showed a loss of 6 to 7 kg in 3 months and 12.3kg in 6 months. There are many different weight loss drugs, and all have risks, benefits, and side effects. Only your healthcare provider can guide you toward the best treatment plan.

Insurance and Cost Comparison

 

Usually, insurance agencies do not cover weight loss medicines. Your plan will determine your coverage for Wegovy vs. Phentermine. As Wegovy was only recently approved, it is more expensive than Phentermine. Also, Wegovy is available only under the brand name, thus being more expensive.

Is Phentermine Safer Than Wegovy?

 

Phentermine is a Schedule 4 controlled substance. It has a chance of misuse and addiction in comparison to Wegovy. In case of tolerance, discontinue the drug immediately. Never increase the dose on your own if the drugs fail to be effective, as it can lead to serious health complications.

 

Phentermine is also associated with pulmonary hypertension, which is a fatal lung disease. Look out for symptoms of shortness of breath, leg swelling, fainting, and chest pain. Seek medical attention in case of an emergency.

 

As mentioned above, this imposes a risk of thyroid cancer. It should be avoided in people with a family history of modular thyroid carcinoma or multiple endocrine neoplasia syndrome type 2.

 

Both drugs should be avoided in pregnant women as they can cause harm to the unborn baby. They can also be present in breast milk; therefore, breastfeeding mothers should not take this medication. Make sure to consult the healthcare provider before starting this medication if you’re pregnant or become ill soon.

Which Is Safer, Wegovy or Phentermine?

 

You cannot determine the answer to that. The effectiveness depends on various factors; however, in one meta-analysis, 

  • Wegovy showed better results were more effective and resulted in more weight loss in 6 months, while for Phentermine, only 5% of the body weight loss was noticed. 
  • Another review showed that Wegovy leads to significant weight loss, similar to gastric bypass surgery. However, older drugs like Phentermine typically showed less impact and had more side effects. Still, the cost and the limited availability of the new drug make things challenging, making Phentermine a viable option.
  • Suppose you’re confused about which medication is suitable for you. In that case, you need to consult with the doctor as they will decide, depending on your health history, medical condition, and what side effects you are willing to take.
  • Different trials show that Wegovy is more effective than Phentermine,  but it is expensive and not readily available. Wegovy, being a new drug invented, is also generally safer. It is ideal for people with high blood pressure or heart problems. 
  • Phentermine is affordable but comes with harsh side effects. Also, Wegovy comes as a tablet and capsule, and Phentermine only as an injection.Only a healthcare provider will decide what’s best for you and help you with your weight loss journey to align with your weight loss goals.
