If you are thinking about taking a prescription diet pill, there are several medications that your doctor might prescribe. One of the most widely used weight loss medications is Adipex-P (phentermine hydrochloride). But just like every weight loss medication, there are Adipex side effects, contraindications, and lifestyle factors that you should consider before taking the pills.

What Is Adipex-P?

Adipex-P is the brand name for a medication called phentermine. Phentermine was approved by the Food and Drug Administration (FDA) in 1959. The medication works to decrease appetite and speed weight loss in people who are also following a low-calorie diet and exercise program.

Adipex is generally prescribed for people with a body mass index (BMI) of 30 or more or for those with a BMI of 27 or more and who also have a weight-related risk factor like diabetes, high cholesterol or controlled high blood pressure.

There are certain people who should not take Adipex-P. These include patients who:

  • Have a history of heart disease (such as coronary artery disease, stroke, arrhythmias, congestive heart failure, uncontrolled high blood pressure)
  • Are taking certain medicines called monoamine oxidase inhibitors (MAOIs) or have taken MAOIs in the past 14 days
  • Have thyroid problems (hyperthyroidism)
  • Have glaucoma (increased pressure in the eyes)
  • Have experienced agitated states or have a history of drug abuse
  • Are pregnant or are nursing
  • Are allergic to sympathomimetic amines such as phentermine, or any of the ingredients

Many patients who follow an Adipex-P weight loss plan take one 37.5 mg tablet or capsule in the morning before breakfast. But your doctor will recommend the best dose for you based on your personal health profile.

Adipex is generally prescribed for short-term weight loss, lasting less than 12 weeks. However, some studies acknowledge that the medication is often prescribed off-label for a longer duration.

Adipex Results

According to the National Institutes of Health, the average weight loss for patients on medications like Adipex-P is approximately 5.8 pounds. But they also note that not everyone loses weight with the diet pill and most people will regain the weight if they don't make permanent changes to their diet and lifestyle.

There are few long-term studies that examine long-term use of Adipex, although as previously noted, it is not uncommon for the medication to be used for longer than 12 weeks.

On study conducted in 1968 evaluated 108 obese women who used the medication (30 mg/day) for 36 weeks. Patients lost approximately 12-13 kg (26-28 pounds) compared to about 11 pounds on placebo. However, just 59 percent of the study participants finished the study, making the results hard to interpret.

Adipex Side Effects

Dieters who take Adipex-P may experience side effects including depression, nervousness, problems sleeping, dry mouth, constipation, unpleasant taste, diarrhea or vomiting. Researchers studying the medication have reported that the most common side effects are dry mouth and insomnia.

The NIH also reports that some patients taking Adipex-P may experience more serious problems including increased blood pressure, heart palpitations, dizziness, tremors, shortness of breath, chest pain, swelling of the legs and ankles or difficulty doing exercises that you can usually do. 

Should I Buy Adipex-P Online?

Because Adipex-P is one of the more popular drugs to lose weight, you'll find many online sources that claim to sell Adipex-P or drugs like Adipex-P. Keep in mind that you need a prescription to get this medication. Many of the companies that sell pills "like Adipex-P" without a prescription have not been verified by the FDA for safety or effectiveness. 

Because this drug can be habit-forming and because you may experience side effects while taking Adipex-P, you should visit your own doctor and review your full health history before you decide to use the medication. If you decide to try the diet medication buy it from a trusted pharmacy. Then communicate with your doctor about any side effects you experience and about whether or not the Adipex-P is helping you to lose weight.
