Phentermine is an inexpensive weight loss medication. It has been proven to be effective for short-term weight loss when used in conjunction with exercise, a reduced-calorie diet program, and behavior change. Phentermine is prescribed for overweight and obese people and those who have weight-related medical problems.
How does Phentermine work?
Phentermine is an appetite suppressant that works like amphetamine. It allows obese and overweight people to lose weight by stimulating the central nervous system, including the brain. This increases the blood pressure and heart rate and thus reducing your appetite. It also increases the amount of energy your body uses to let you lose weight.
However, the use of Phentermine alone won’t let you lose weight. It should be used together with exercise and diet, especially for those with risk factors like diabetes, high blood pressure, and high cholesterol.
How to use Phentermine?
Doctors usually prescribed the lowest possible effective dose. It is usually taken as a single dose in the morning, at least an hour before breakfast or 1 to 2 hours after breakfast. If needed, your doctor may also prescribe you to take it in three small divided doses 30 minutes before each meal.
To get the most benefits, take Phentermine exactly as you are told. The length of treatment usually depends on how well you respond to the drug, but most people take this medication for 3 to 6 weeks. Do not take this late in the day as this may cause sleeping problems. Do not take more than the recommended dose, take it more frequently, or take it for a longer period of time. If you want to discontinue using this medication, inform your doctor. A sudden stop may cause withdrawal symptoms such as severe tiredness and depression.
What are the side effects of Phentermine?
Losing weight and keeping it off can reduce the health risk associated with obesity such as diabetes, heart disease, high blood pressure, and a shorter lifespan. However, a weight-loss drug like this one is not without risk and side effects. The most common but well-tolerated reported side effects are:
- Dry mouth
- Sleeping problems
- Flushing of the skin
- Nausea and vomiting
If any of the above side effects get worse, contact your doctor right away.
Serious side effects include:
- Heart palpitations
- Uncontrolled muscle movements
- Mood changes such as nervousness, hallucinations, agitation, and uncontrolled anger
- Change in sexual interest or ability
- Severe headache
- Vision changes
- Weakness on one side of the body
- Difficulty breathing with exercise
- Swelling of the leg, feet, or ankles
- Allergic reactions with signs like itching, rash, severe dizziness, swelling of the face, and trouble breathing
In case of serious side effects, stop using this medication and seek medical attention immediately.
