Phentermine is a weight-loss medication which is prescribed to obese and overweight people in order to reduce the body weight. This appetite suppressant medication belongs to a drug class known as sympathomimetic amines. The exact mechanism through which this medication helps one to lose weight cannot be clearly defined; for some, it decreases the appetite levels, by affecting certain brain parts of the brain or by increasing the energy usage in the body.
Although losing weight protects a person from health risks associated with diabetes (for example, high blood pressure, diabetes and heart disease), Phentermine should carefully be taken in order to experience its weight-loss benefits. For instance, it should be taken with a doctor-approved reduced-calorie diet program, behavior change, and exercise.
Before Phentermine medication is administered, a patient should inform the doctor if he/she has any history of:
- Agitated states
- Drug abuse
- Idiosyncrasy or hypersensitivity to Phentermine
- Cardiovascular disease (e.g. uncontrolled hypertension, coronary artery disease, congestive heart failure, arrhythmias, stroke, etc.)
How to Safely Take Phentermine?
This medication should be taken by mouth as per the doctor’s directions, usually once each day, an hour prior to breakfast or 1-2 hours after breakfast. In some cases, the doctor may adjust the prescription and increase the dosage, in that case, the patient is advised to take small doses 3 times, each day. You should always follow your healthcare provider’s instructions carefully. The medication shouldn’t be taken late in the day since it might cause insomnia (trouble sleeping).
For patients using sustained-release capsules, it is safe to take the dose once before breakfast daily or 10-14 hours, before bedtime. The medication should be swallowed whole. You should always avoid chewing or crushing sustained-release capsules at all costs. This is because chewing and crushing bring down the efficiency of the medication.
If the tablets you are using dissolve in your mouth, it’s recommended to take the dose once a day – especially in the morning – either with food or without. Ensure that you handle the tablet with clean and dry hands. You can either swallow the pill with water or allow it to dissolve on the tongue.
In most cases, the medication is administered based on the patient’s response to therapy and his/her medical condition. The doctor alters the dosage strength by taking into consideration the body’s response to the medication. Therefore, the medication should be used exactly and regularly in accordance with the doctor’s prescription, so as to accrue its benefits. Taking the medication the same time(s) every day is a great way of helping yourself remember.
Consumption of this medication in high doses or for a prolonged duration results in withdrawal reactions. In such cases, the patient experiences withdrawal symptoms (for example, severe tiredness, depression etc.) after he/she suddenly stops the medication. Reducing the dosage strength gradually helps to prevent withdrawal symptoms. For more details, visit your pharmacist or doctor and report any symptoms of withdrawal reactions immediately.
This medication, though very rarely, can bring about abnormal drug-seeking behavior – such as addiction. Therefore, to prevent this, avoid taking increased dosage, prolonged usage or taking Phentermine more frequently than prescribed. Follow the directions.
The medication should not be used along with weight-loss drugs including herbal products, over-the-counter medicines, prescription medicines, and other serotonergic agents – paroxetine, fluoxetine, fluvoxamine, and sertraline. Therefore, it’s not advisable to co-administer Phentermine with other prescription drugs. Drug interaction triggers unwanted health repercussions making a person suffer to a greater extent. Hence, consult the doctor before taking any other medicine along with phentermine.
