Let’s recall the main fact: Phentermine is for helping people with excess body fat. If your progress in eliminating body fat stops, this article is for you. You will know why an anorectic may or may not work for you and what to do if the treatment doesn’t improve your figure or is slower than expected.

We’re here to help find solutions that work for you, and luckily, there are several options you can use if you want to know how to make Phentermine work again.

You may understand that Phentermine stopped working if you notice the following:

  • Waist circumference and weight don’t decrease.
  • You have increased and/or extended feeling of hunger between meals.
  • You need more food to feel full.

It can happen to anyone.

Don’t worry and don’t give way! Don’t give up on your goals.

In case of Phentermine not working anymore, consult a bariatrician. A licensed doctor is an excellent source of useful and reliable information. He will tell you what to do next in your situation.

One of the measures listed below may help:

  • Make sure you take the drug right: daily, as early as possible in the morning.
  • Take the highest possible dosage as prescribed by your doctor.
  • Adjust the weight management plan in terms of diet changes and increased levels of exercise.
  • Get more rest and avoid stressful situations. Many people underestimate the importance of sleep and stress management for successful weight loss.
  • You have to wait a little if you have reached a plateau (temporarily stopping the process of losing weight). Over time, the process can resume.

Phentermine is not a magic pill that completely suppresses appetite and starts the fat burning process. You still need to make efforts and watch how you eat and what lifestyle you lead. If nothing helps and you don’t get the desired results, your doctor may recommend stopping Phentermine and/or starting another treatment.

What to take if Phentermine doesn’t work

Important information! Using other medicines won’t make Phentermine work again. Moreover, when combined with some drugs, including appetite suppressants, it can cause severe adverse reactions.

To start new medication treatment for overweight or obesity, you must stop taking Phentermine and wait a few days for the drug to completely clear from your body.

Phentermine tolerance break

It is essential to understand the nature of the appetite suppressants prescribed for you and work with your doctor to monitor their effects on your body. You should be aware that the effectiveness of Phentermine decreases over time, and unfortunately, you can’t do anything about it.

This phenomenon is known as tolerance. It develops when you regularly take a drug. Phentermine at the current dose stops working as well as it did earlier.

That’s why the standard treatment should not exceed 12 weeks. You may continue the treatment if you see that the drug suppresses your appetite and you lose weight.

A tolerance break is the interruption of the Phentermine cycle and a reply to the issue of how to make Phentermine work again. It is necessary for the body to start responding to the drug again. Your doctor will tell you how long it will take before you can restart the medication treatment for obesity.


If Phentermine stops working as well as it used to, it’s not the end of the world. It is crucial to determine the cause of what is happening. Visit a doctor for a consultation. He may prescribe a new dose, adjust your treatment plan, or recommend stopping the treatment.
