What to know about phentermine side effects
Where side effect information comes from
Phentermine is an FDA-approved prescription appetite suppressant used for weight management. It is a generic medication, not a compounded formulation.
Because it is a prescription medication, it carries an FDA-approved label. That label is the source for any list of possible side effects.
This page does not list them for you, and it does not rank them or describe how likely any one of them is. A licensed provider reviews the label with you in the context of your own health history.
Your pharmacy also supplies the label information with your medication. Read it, and bring your questions to your provider.
How a Persona provider monitors your plan
A licensed physician prescribes phentermine only after an individualized clinical assessment. That assessment looks at your health history before anything is prescribed.
The prescribing physician sets the timing and duration of your plan. The same physician monitors your progress over time and adjusts the plan.
Monitoring is part of the plan, not an extra step. What you report between visits feeds directly into what your provider decides next.
How to raise a concern between visits
If you notice something you did not expect, tell your care team. You do not need to wait for a scheduled visit to bring it up.
It helps to describe what you noticed, when it started, and whether it is still happening. Your provider can then ask follow-up questions.
Only your provider can advise you on what to do next, including whether anything about your plan should change. Do not make that call on your own based on what you read here.
If you think you are having a medical emergency, seek emergency care right away.
What the medication does
Phentermine works on the neurotransmitters in the brain that control appetite. It reduces hunger and cravings, which makes a reduced-calorie diet easier to follow.
It supports weight loss when combined with a reduced-calorie diet. No special or pre-packaged food is required.
With Persona, the initial medical consultation is free, and medication is delivered directly to you.
Common questions about phentermine side effects
What are the common side effects of phentermine?
Possible side effects are listed in the FDA-approved label for phentermine, and in the information that comes with your prescription. This page does not reproduce that list or rank the items in it. A licensed provider reviews that information with you during your consultation, based on your own health history and current medications.
Should I stop taking phentermine if I notice a side effect?
That is a decision for the physician who prescribed it. Contact your provider and describe what you noticed. Your provider monitors your plan and adjusts it when needed. If you think you are having a medical emergency, seek emergency care right away.
How do I tell my Persona provider about a side effect between visits?
Message your care team through your Persona account. You do not need to wait for your next scheduled visit. Describe what you noticed, when it started, and whether it is ongoing. Your provider can follow up with questions from there.
How long will I be on phentermine?
Timing and duration are set by the prescribing physician. There is no single answer that applies to everyone. Your physician monitors your progress and adjusts the plan over time.
Is phentermine a compounded medication?
No. Phentermine is an FDA-approved generic prescription medication, not a compounded formulation. Because it is FDA-approved, it has an approved label that documents its possible side effects.
How do I find out whether phentermine is appropriate for me?
A licensed physician decides that after an individualized clinical assessment. The initial medical consultation is free. If a prescription is appropriate, medication is delivered directly to you. No special or pre-packaged food is required.
