There are quite a few reasons mixing alcohol and phentermine isn’t a good idea:

  • It makes the risk of serious interactions and side effects more likely.
  • It can reduce the effectiveness of the phentermine.
  • Drinking generally isn’t a good idea when you’re trying to lose weight.
  • There is also a potential for abuse with the use of Phentermine, and mixing alcohol and Phentermine may make you more likely to abuse one or both substances, or to become addicted.

Side Effects Mixing Alcohol and Phentermine

People taking phentermine are warned against mixing it with alcohol. First, the interactions and side effects of mixing alcohol and phentermine are likely to be more severe than with either substance on its own. For example, phentermine side effects can include dry eyes, sleep problems, and issues with heart rate and high blood pressure. All these can be made worse when mixing alcohol and phentermine.

Cardiovascular Side Effects

The makers of phentermine also warn that when mixing alcohol and phentermine, you may be at a higher risk of cardiovascular side effects such as chest pain and raised blood pressure. Even having only a small amount of alcohol can raise the risk of having a heart attack or stroke if you’re obese, have heart disease and are taking phentermine.

Inhibit Weight Loss

Finally, remember that Phentermine is prescribed for weight loss. Mixing it with alcohol can be counterproductive for that goal, since there are a lot of ways that alcohol use can sabotage weight loss efforts. For example, alcohol is full of sugar and calories. It can make you feel tired and less likely to be physically active. You may be more likely to make the wrong food choices when you’re drinking. Since alcohol affects the liver, it may also make it harder for your body to burn fat. 

What is Phentermine?

Phentermine is a commonly used weight loss drug in the United States. Phentermine is the generic name of a drug that’s sold as the brand names Adipex-P, Ionamin, and Pro-Fast. It’s primarily prescribed to people who are clinically obese or who have medical problems that are related to their weight.

Can Phentermine Be Abused?

Another reason you shouldn’t mix alcohol with phentermine is that it raises your risk of addiction. Phentermine is a controlled substance with the potential for abuse. It is designed for short-term use, and it’s generally reserved for people with a body mass index of more than 30. Because it is a stimulant, it can be used to create a high, particularly when someone takes large doses.

If someone takes it for longer than they’re instructed or takes large doses, they may experience addition or other effects of withdrawal like depression or fatigue when they attempt to stop taking it.

People with a history of drug or alcohol abuse are advised not to take phentermine.
