The main thing you should know about the compatibility of Phentermine with alcohol: they are incompatible.

Moreover, alcohol interferes with weight loss by reducing the effectiveness of Phentermine. Also, combining Phentermine and a glass of wine (for example) can lead to side effects.

Problems of the drug interaction with alcohol are due to a different mechanism of their action. Phentermine is a stimulant, and alcohol reduces and even suppresses activity, so they are mutually exclusive.

Side effects of Phentermine and alcohol when taken together:

  • higher risk of cardiovascular problems (high blood pressure, increased heart rate, chest pain);
  • dizziness;
  • drowsiness;
  • depression;
  • concentration disorder;
  • nervousness.

Alcohol creates a feeling of hunger, thereby interfering with the main function of Phentermine to reduce appetite. At the same time, the level of energy which the release of the drug provokes also decreases.

Phentermine is more effective when it stays in the body for a long time. It is due to the level of alkali in the pH balance. Alcohol adversely affects this balance, thereby preventing phentermine from being stored in the body.
