What is Phentermine?
Phentermine is a prescription medication primarily used as an appetite suppressant. It is available under various brand names such as Adipex-P, Lomaira, and also as a generic drug. Phentermine works as a short-term treatment for obesity, typically used in conjunction with diet, exercise, and behavior modification to enhance weight loss.
This medication is classified under a group of drugs known as sympathomimetic amines, which are similar to an amphetamine. By stimulating the central nervous system, Phentermine increases heart rate and blood pressure and decreases appetite.
How Does Phentermine Work?
Phentermine helps in weight reduction by initiating the release of certain chemicals in the brain regions responsible for hunger regulation. It signals the release of norepinephrine, a neurotransmitter that activates the response associated with 'fight or flight,' thus helping individuals feel full and reduce their calorie intake.
As a CNS stimulant, Phentermine also boosts energy levels, which can encourage people to engage in physical activities they might otherwise avoid due to fatigue or energy depletion. It's crucial for it to be used under medical supervision as part of a comprehensive treatment plan that includes lifestyle changes.
Usage and Dosage Guidelines
Phentermine is usually prescribed for a few weeks as part of an overall weight loss program. The dosage varies based on the formulation: typical forms are capsules or tablets that are taken orally once a day. It's often advised to take Phentermine early in the day—before breakfast or a couple of hours after breakfast—to prevent insomnia or restlessness.
The exact dosage and duration are determined by a healthcare provider, taking into account the patient’s medical condition, weight loss goals, and response to treatment. Self-adjusting the dosage without consulting a healthcare provider is strongly discouraged due to potential health risks.
Possible Side Effects
Like any medication, Phentermine can cause a range of side effects. Common side effects include increased heart rate, dry mouth, insomnia, anxiety, constipation, and jitteriness. Most side effects are relatively mild and tend to taper off as the body adjusts to the medication.
However, more severe side effects should prompt immediate medical attention. These can include:
- Swelling of legs and ankles (edema)
- Severe chest pain
- Significant mood changes
- Trouble breathing
Interactions and Precautions
Before taking Phentermine, it is essential to disclose all medications and supplements being currently used, as these could potentially interact with Phentermine. Notably, drugs like MAO inhibitors and other weight-loss drugs can interact adversely with Phentermine.
Considerations for specific populations: Phentermine should not be used by individuals with a history of cardiovascular disease, hyperthyroidism, glaucoma, or drug abuse history. It’s not recommended for pregnant or breastfeeding individuals, emphasizing the importance of consultation with a healthcare provider before starting this medication.
