Is There a Better Weight Loss Medication Than Phentermine?

Phentermine and Semaglutide are two different medications that patients use to support their weight loss efforts.

Phentermine is a short-term use medication in capsule form. It’s one of the oldest weight loss medications on the market, having been approved back in 1959. Semaglutide, on the other hand, is one of the newest and hottest weight loss injection medications, with approval in 2021. In addition, Semaglutide is useful in a long-term weight loss plan with higher doses.

The best weight loss medication depends on your needs and goals. Let’s review the differences between Phentermine and Semaglutide to see which works for you.

Phentermine Vs. Semaglutide for Weight Loss

What Does Phentermine Do For Weight Loss?

Phentermine impacts norepinephrine levels, increasing heart rate and blood pressure, breaking down fat, and raising blood sugar. However, in the form of an extended-release medication, these processes help give you more energy to burn calories better.


Throughout the day, Phentermine lessens the appetite. This helps patients to control their appetite because they don’t feel the urge to eat so often.


This medication is part of a complete weight loss plan, meaning you should combine it with a nutritious diet and proper exercise.

The Ideal Phentermine Candidate

You might be a good candidate to harness the power of Phentermine if you are obese or overweight and struggling to improve your health on your own. It’s okay to need help, after all.


An ideal candidate will have a higher BMI than 30 or higher than 27 BMI with other health conditions.


Sometimes even the most dedicated healthy lifestyle just can’t compete against genetics, hormones, or medical conditions. As a result, many patients face the challenge of repeatedly gaining weight back, which can take its toll both physically and mentally. Phentermine can help.


You should not take Phentermine if you:

  • Have heart disease
  • Are pregnant
  • Have high blood pressure
  • Have an overactive thyroid gland
  • Are diagnosed with glaucoma
  • May become pregnant
  • Are breastfeeding

How Phentermine Works

As a prescription medication, Phentermine is a capsule that you take with water. Patients take the medication in the mornings, with or without food, and your provider will help you determine the proper Phentermine dosage to start impacting your weight loss journey. Once you start, the prescription has approval for up to 12 weeks of use.

Phentermine Side Effects

Phentermine is best taken in the morning, around the same time every day. Because it is long-lasting, the medication can make it challenging to fall asleep or stay asleep if taken in the evening.

Some of the side effects of Phentermine include:

  • Nervousness
  • Constipation
  • Faster heart rate
  • Fatigue
  • Diarrhea
  • Headache
  • Tingling

While using this medication, you should not be drinking alcohol. Alcohol can make these side effects worse if you have them. Instead, focus on hydrating with plenty of fluids.

Is Semaglutide a Good Weight Loss Drug?

Semaglutide is a prescription that is highly effective in reducing hunger cravings, keeping you full for longer, and improving your overall health and wellness. Many patients find that this is the solution to easily shedding pounds and keeping the weight off.

Because of the way Semaglutide works, your weight loss results depend on your dosage, length of prescription, and lifestyle. You should have a good medical team supporting you along the way to optimize your progress. They can offer the best advice on reducing calories, eating healthily, and staying active.

Of course, you don’t need to take our word for it. Some of our patients share their experiences in these Semaglutide before and after pictures. See for yourself the difference that Semaglutide can make.

How Semaglutide Works

There is a gut hormone called glucagon-like peptide-1 (GLP-1) that our body releases after we eat. One of its main purposes is to slow down food movement in the gut so you naturally feel fuller longer.

Semaglutide acts the same way as GLP-1 to:

  • Improve insulin production
  • Intentionally slow stomach emptying
  • Reduce the appetite
  • Lower sugar production in the lover
  • Decrease muscle insulin sensitivity

Patients should combine Semaglutide with a proper diet and an active lifestyle, like Phentermine. Unlike Phentermine, Semaglutide treatments can last up to 20 weeks.

This medication is a weekly injection for obese or overweight individuals, along with metabolic health conditions such as type 2 diabetes or hypertension.

The easy part is that you only need to pick up your pre-filled syringes once a month. Semaglutide is an injection that can be done from the comfort of your home.

What Are the Main Side Effects of Semaglutide?

One common side effect is nausea, which typically happens when starting the medication.

Both Semaglutide and Phentermine come with the possibility of regaining weight after treatment. This is why you must have the right support to continue making impactful lifestyle changes.
