Here is what you need to know if you are considering taking phentermine.
What Is Phentermine?
Phentermine is an anorectic drug that stimulates the brain and central nervous system. It helps reduce appetite and increases metabolism. Doctors usually prescribe it to individuals with obesity, especially those with conditions like high blood pressure or diabetes.
Phentermine has a mechanism of action on the nervous system similar to the action of amphetamines. However, it is relatively safer when used as per the doctor’s prescription and for a short duration. Its main purpose is appetite suppression, which supports effective weight management.
How Does Phentermine Work?
Phentermine works by influencing the brain’s neurotransmitters, which can help reduce hunger and increase feelings of fullness. As a result, it helps individuals eat less, which contributes to weight loss when combined with a healthy diet and exercise plan.
Phentermine’s impact on the body includes increasing heart rate and blood pressure. For this reason, individuals with certain health conditions need to exercise caution.
Who Should Use Phentermine?
Phentermine is not suitable for everyone. It’s primarily prescribed for people who have a body mass index (BMI) of 30 or higher, or a BMI of 27 or higher with additional health risks like high blood pressure, diabetes, or high cholesterol. It is a short-term weight loss aid that works best when used in combination with a well-balanced diet and regular physical activity.
Precautions to Take Before Using Phentermine
Before starting phentermine, ensure you inform your doctor if you have:
- Heart disease or a history of heart problems.
- Uncontrolled high blood pressure.
- Overactive thyroid.
- Glaucoma.
- History of drug abuse.
Additionally, phentermine should not be used during pregnancy, as weight loss could harm the unborn baby. It is also unsafe for breastfeeding mothers.
How to Take Phentermine Safely
Phentermine is typically taken once a day, either 1 to 2 hours after breakfast or before breakfast, depending on the prescribed dosage. It is essential to follow your doctor’s instructions closely and never take more than the prescribed dose. Taking larger amounts can lead to serious side effects and complications.
Phentermine is meant for short-term use—usually no more than a few weeks. Over time, the effects of appetite suppression may decrease, and phentermine may not work as well.
What Happens if I Miss a Dose?
If you miss a dose of phentermine, take it as soon as you remember. However, if it is later in the day, skip the missed dose and take your next dose as scheduled. Never double up on doses to make up for a missed one.
