Adipex, also known as Adipex-P, is a prescription diet pill that has FDA approval to be prescribed to treat obesity. It may also be prescribed to individuals who need assistance in bringing their weight down to a healthier level to help reduce the risk of weight related health conditions such as:
  • Type 2 diabetes
  • Heart disease
  • High blood pressure 

How Adipex Functions 

Adipex contains the drug phentermine, which is a sympathomimetic amine. It works in a way that is similar to the function of amphetamines in the body. It stimulates the central nervous system in order to produce a reaction in the hypothalamus part of the brain. It is in that part of the brain that the chemical called norepinephrine is produced. That substance is responsible for the “fight or flight” response in the body. It also increases the heart rate and blood pressure, resulting in a suppressed appetite.

Appetite suppression is the center of the benefits of Adipex. This is because when it is prescribed, the physician will also recommend that the patient follow a healthy, reduced calorie, portion controlled diet. Though this would typically produce hunger in many dieters, with a suppressed appetite, there is a feeling of “fullness” achieved with a smaller amount of food. Furthermore, the need to snack and the sensation of food cravings is reduced.

Also prescribed along with this drug is a daily exercise plan that is suitable to the fitness level of the dieter. Adipex also helps to support that effort by providing an energy boost. This makes it easier to avoid the fatigue that often results from a reduced calorie diet. Learn More About Adipex at

What about Side Effects?

If you were wondering if there is a risk of unwanted side effects when taking Adipex diet pills, the short answer is yes.

While many people can take this medication without any problems, this drug has been linked to certain side effects. The most common of these include:

  • Headache
  • Constipation
  • Jitters
  • Irritability
  • Dry mouth
  • Difficulty sleeping
  • Digestive upset (nausea, vomiting, constipation and diarrhea)
Many of these mild symptoms can sometimes fade away after the first few days of use. That being said, if they should persist or worsen, inform your doctor right away.

Furthermore, there are other adverse effects that are more severe. On more rare occasions, strong side effects may occur. Some of these may include:

  • Seizures
  • Convulsions
  • Very high blood pressure
  • Fast, irregular pounding heartbeat
  • Mental/mood changes
  • Change in sexual interest/ability
  • Uncontrolled muscle movements,
If you should experience any serious side effect or a severe allergic reaction, obtain emergency medical assistance right away.

Additionally, another drawback of Adipex is that it is a short term use drug that risks addiction with extended use. However, some studies have found that phentermine abuse or addiction does not occur in patients treated with this drug for obesity.

Nevertheless the potential risk of addiction may be higher in individuals who have a history of alcohol and/or drug abuse. 

It is Important to Take This Obesity Medication as Prescribed

Adipex should be taken exactly as it has been prescribed. This is important because improper use of this medication may cause it not to work as effectively and/or could increase your risk of unwanted side effects.

A prescription for this diet pill will typically last no longer than a few weeks. Throughout that time, the body builds a tolerance, decreasing the drug’s effectiveness.

However, increasing the dosage will not improve the benefits of the drug, but will only risk severe side effects. If too much of this medication is used or if it is continued for too long, withdrawal symptoms may occur when its use is ceased.

It is important that you maintain an open discussion with your doctor when taking this medication. You should be monitored while taking it and you should follow all directions as they have been given. If you think your dosage should be changed, inform your doctor and trust his/her advice.

Additionally, make certain that you inform your doctor of your medical history, past and present. Let him/her know if you are pregnant, nursing or planning on becoming pregnant, or if you have a medical condition, are taking medications (prescription or non-prescription), herbal or other dietary supplements.
