What is Phentermine?
Phentermine (also known as Adipex P, or Lomaira), a medication that reduces appetite, is a norepinephrine-reuptake inhibitor. This medication can aid in weight loss by reducing the feeling of being hungry.
Like other weight-loss medications, Phentermine is meant to be part of a weight-loss plan. It works best when used in combination with healthy eating, physical activity, and behavior change.
People with high cholesterol, metabolic syndrome, obesity, or who are overweight should talk about taking Phentermine with a trusted medical authority if they haven’t been successful in losing enough weight through diet and exercise alone.
How Does Phentermine Work?
Phentermine is a prescription drug that belongs to a class of drugs known as “anorectics“. These drugs are used to suppress appetite and promote weight loss.
Phentermine works by increasing the levels of certain neurotransmitters in the brain, such as norepinephrine, dopamine, and serotonin, which can make you feel fuller and less likely to eat.
Contrary to popular belief, Phentermine does not promote fat loss or affect your metabolism. The entire mode of function of the weight-loss drug simply falls on making it easier for you to restrict calories.
How to use Phentermine
Phentermine is usually taken once a day, either 1 hour before breakfast or 1-2 hours after breakfast. Your doctor may adjust the dose if needed, but it is advised not to take more than 3 doses daily.
It is important to follow your doctor’s instructions carefully. Additionally, if you take phentermine late in the day, it may make it hard for you to sleep at night.
If you use a type of phentermine that comes in a slow-release capsule, you should take it once a day before breakfast or at least 10-14 hours before bedtime. Make sure to swallow the capsule whole and do not crush or chew it. If you do, it could release all the medicine at once and increase the risk of side effects.
It is advised not to stop taking phentermine suddenly, as you may experience withdrawal symptoms like depression or extreme tiredness. To prevent this, your doctor may slowly lower your dose. You are more likely to have withdrawal symptoms if you have taken phentermine for a long time or in high doses. If you experience withdrawal symptoms, tell your doctor or pharmacist right away.
Phentermine can sometimes cause addiction, especially if you have a history of substance abuse. Do not take more of it, take it more often, or take it longer than prescribed. Follow your doctor’s instructions for stopping the medication.
This medication may not work as well after you have been taking it for a few weeks. If this happens, talk to your doctor. Do not increase the dose unless your doctor tells you to. Your doctor may also tell you to stop taking the medication.
How Much Weight Can You Lose With Phentermine?
Phentermine is a medication that is approved by the FDA for short-term use (less than 12 weeks) for weight loss. It is often prescribed off-label for longer periods of time. When taken for 3 months, it can lead to an average weight loss of 3% of initial body weight, and 5-7% after 6 months. Depending on a number of factors like diet and exercise, some people may experience more weight loss than this.
Its effectiveness may decrease after prolonged use of more than a year due to tolerance built up over time. It may be more effective when combined with topiramate, a drug that is used to treat seizures and has appetite-reducing properties.
The combination of phentermine and topiramate is sold under the brand name Qsymia and was approved by the FDA in 2012 for use in combination with lifestyle changes such as increased exercise and a calorie-reduced diet.
Qsymia was found to have the highest odds of leading to at least a 5% weight loss compared to three other commonly prescribed weight loss drugs. When taken for more than 56 weeks, it can lead to an average weight loss of 17.8 pounds.
Weight loss with this medication is also accompanied by improvements in insulin sensitivity, blood sugar management, and reduction in blood pressure.
Phentermine Side Effects
Common side effects of phentermine and the combination of phentermine and topiramate include:
- dry mouth
- sleep problems
- heart palpitations
- skin flushing
Rare but severe side effects are also possible, such as increased blood pressure, suicidal thoughts, metabolic acidosis, increased creatinine levels, fetal harm, vision problems, cognitive impairment, and low potassium levels.
Phentermine should not be taken by people with heart disease, hyperthyroidism, glaucoma, severe kidney or liver disease, or those who are pregnant or nursing.
It should also not be used in combination with monoamine oxidase inhibitors (MAOIs) or certain other medications. A healthcare professional will determine whether phentermine is appropriate and safe for an individual.
