Phentermine 25 mg

Overview

Phentermine is a prescription sympathomimetic medication that may be used as a short-term adjunct to a reduced-calorie diet and increased physical activity for weight management in certain adults with obesity or overweight accompanied by weight-related health risks.

Phentermine works primarily by reducing appetite through effects on the central nervous system. It is intended to be used as part of a comprehensive weight-management program and is not a substitute for a balanced diet, physical activity, or medical care.

Phentermine can cause dependence and other serious adverse effects and should be used only under the supervision of a qualified healthcare professional.

Uses

Phentermine may be prescribed for short-term weight management in appropriately selected patients when lifestyle measures alone have not provided adequate results.

The medication should only be used for the condition and duration recommended by the prescribing healthcare professional.

Dosage and Administration

The appropriate dose depends on the specific formulation, medical history, response to treatment, and other medications being taken.

Take phentermine exactly as prescribed. Do not increase the dose or take it more frequently to obtain faster weight-loss results.

Follow the instructions supplied with the specific product because different phentermine formulations may have different dosing requirements.

Common Side Effects

Possible side effects include:

• Dry mouth
• Increased heart rate
• Increased blood pressure
• Nervousness
• Restlessness
• Difficulty sleeping
• Headache
• Dizziness
• Tremor
• Gastrointestinal discomfort
• Constipation

Because phentermine can affect alertness and cardiovascular function, use caution when driving or operating machinery until you know how it affects you.

Serious Side Effects

Seek prompt medical attention for:

• Chest pain
• Shortness of breath
• Fainting
• Severe or persistent headache
• Rapid or irregular heartbeat
• Severe agitation or confusion
• Significant increases in blood pressure
• Signs of an allergic reaction

Rare but serious cardiovascular or pulmonary complications can occur.

Warnings and Precautions

Phentermine may not be appropriate for people with certain cardiovascular conditions, uncontrolled high blood pressure, hyperthyroidism, glaucoma, or a history of certain substance-use disorders.

Tell your healthcare professional about all medical conditions and medications before starting treatment.

Phentermine can cause dependence and should not be taken by someone for whom it was not prescribed.

Drug Interactions

Tell your healthcare professional about all prescription medicines, over-the-counter medicines, supplements, and other substances you use.

Particular caution may be required with:

• Certain antidepressants
• Monoamine oxidase inhibitors (MAOIs)
• Other stimulant medications
• Other weight-loss medicines
• Medicines that affect blood pressure or heart rate

Do not combine phentermine with another weight-loss medication unless specifically directed by a healthcare professional.

Pregnancy and Breastfeeding

Phentermine should not be used for routine weight loss during pregnancy. Weight loss offers no potential benefit during pregnancy and may harm the fetus.

Tell your healthcare professional if you are pregnant, planning to become pregnant, or breastfeeding before using phentermine.

Dependence and Withdrawal

Phentermine is a stimulant medication with potential for misuse and dependence. Taking more than prescribed or using it for longer than recommended can increase these risks.

Do not share the medication or use someone else’s prescription.

Overdose

An excessive amount of phentermine can cause serious symptoms, including severe agitation, confusion, tremors, rapid heartbeat, high blood pressure, abnormal heart rhythms, seizures, or loss of consciousness.

If an overdose is suspected, seek emergency medical assistance or contact your local poison-control service immediately.

Storage and Disposal

Store phentermine securely and out of reach of children and anyone for whom it was not prescribed.

Do not share prescription medication. Dispose of unused medication according to local pharmacy or healthcare-authority recommendations.

Important Safety Information

Phentermine should be used only under appropriate medical supervision and exactly as prescribed. It is intended to support a broader weight-management program rather than provide a standalone solution for weight loss.

Do not increase the dose because weight loss appears slow, and do not combine it with other stimulants or weight-loss medicines without medical advice.
