Considering weight loss medication? Here's what to know before starting phentermine.
Phentermine is one of the most widely prescribed appetite suppressants in the U.S., often used to support patients as part of a medically supervised weight loss plan. At Envizion Medical, we offer phentermine as a short-term tool to help you jumpstart your weight loss journey—but it’s not for everyone.
In this article, we’ll explore how phentermine works, who it may benefit, and what you can expect when partnering with our expert team.
Phentermine is an FDA-approved prescription medication that suppresses appetite by stimulating the central nervous system. It works similarly to amphetamines and is typically prescribed for short-term use to assist patients who have struggled to lose weight through diet and exercise alone.
It’s most effective when combined with a comprehensive weight loss plan that includes nutritional guidance, physical activity, and behavioral support.
Phentermine may be appropriate for adults who:
Have a Body Mass Index (BMI) of 27 or higher with associated health risks (such as high blood pressure, insulin resistance, or sleep apnea)
Struggle with appetite control, portion control, or emotional eating
Are not pregnant or breastfeeding
Do not have a history of cardiovascular disease, uncontrolled hypertension, hyperthyroidism, or certain psychiatric conditions
At Envizion Medical, we conduct a thorough health assessment before prescribing phentermine to ensure it’s a safe and appropriate option for you.
When taken under the supervision of a licensed healthcare provider, phentermine can be a safe and effective tool for short-term weight loss. However, it is not suitable for everyone. Certain medical conditions—such as heart disease, glaucoma, or severe anxiety—may increase the risk of adverse effects.
Our providers monitor patients closely throughout treatment to ensure safety and optimize results. Regular check-ins, coaching, and lab reviews help us tailor your plan and address any side effects or concerns that may arise.

How long can I take phentermine?
Phentermine is typically prescribed for up to 12 weeks. However, the exact duration will depend on your progress, goals, and how your body responds to treatment. Our team evaluates each patient on a case-by-case basis.
What are the side effects of phentermine?
Common side effects include dry mouth, restlessness, insomnia, constipation, and increased heart rate. These can often be minimized with proper hydration, dosage adjustments, and supportive care. Serious side effects are rare but will be closely monitored.
Can I take phentermine with other medications?
This depends on your current prescriptions and medical history. Be sure to bring a complete list of medications and supplements to your consultation. Certain medications—such as MAO inhibitors or stimulants—may interact negatively with phentermine.
Will I regain weight after stopping phentermine?
Weight maintenance depends on long-term lifestyle habits. At Envizion Medical, we focus on sustainable changes through nutrition coaching, exercise planning, and mindset support, so you’re equipped to maintain your progress even after discontinuing medication.
Can phentermine cause addiction?
Phentermine is a controlled substance due to its chemical similarity to amphetamines. While physical dependence is rare when used as prescribed, it is important to follow dosing guidelines and attend all follow-ups to ensure responsible use.
How quickly will I see results?
Many patients begin noticing changes within the first few weeks, especially when combining medication with dietary changes and increased activity. Results vary based on individual metabolism, lifestyle, and compliance with the recommended plan.
