Phentermine is a prescription drug that is an anorectic drug. It is used as a short-term treatment for obesity and is intended to be used in conjunction with a healthy diet, exercise, and lifestyle changes. This drug stimulates particularly norepinephrine, dopamine, and serotonin, in the brain. These neurotransmitters play a role in regulating appetite, mood, and energy levels.
Phentermine primarily works by suppressing appetite, which is a key factor in its role as a weight loss medication. The regulation of appetite involves complex interactions between various areas of the brain and different chemical messengers. Phentermine’s mechanism of action involves influencing these pathways to reduce the feeling of hunger and promote a sense of fullness.
The drug stimulates the release of norepinephrine and dopamine, two neurotransmitters that play a role in appetite regulation. Norepinephrine, in particular, acts on various parts of the brain to signal a decrease in hunger. Dopamine is associated with pleasure and reward and can contribute to a sense of well-being, potentially reducing the emotional eating often linked to obesity.
The hypothalamus is a crucial region in the brain that plays a central role in appetite control. Phentermine stimulates the hypothalamus, which leads to the release of neurotransmitters that signal the body to decrease hunger and increase the feeling of satiety.
Sympathetic Nervous System Activity
Also, it triggers the sympathetic nervous system, popularly known as the “fight or flight” reaction. Energy expenditure rises as a result of this stimulation, while appetite declines. By burning more calories, the elevated energy expenditure can help people lose weight.
Reduced Ghrelin Levels
Ghrelin is often referred to as the “hunger hormone” because it stimulates appetite. Phentermine helps to reduce the secretion of ghrelin, leading to a decrease in hunger sensations.
Enhanced Serotonin Effects
A neurotransmitter dubbed serotonin is involved in controlling hunger and mood. The medicine might elevate mood and lessen emotional eating by affecting serotonin levels.
The indicated Phentermine dosage of 37.5 mg is not strictly thought of as the “best” for everyone; rather, it is a typical dosage that has been frequently administered. The dosage is determined by a person’s weight, medical history, response to the medicine, and tolerance to its effects, among other personal considerations. A healthcare professional will normally choose the dosage based on these considerations in order to achieve the intended appetite suppression while reducing potential negative effects.
Some reasons why Phentermine 37.5 mg might be a commonly prescribed dosage are discussed here.
In the immediate-release formulation of phentermine in tablet or capsule form, adults typically commence with a starting dose ranging from 15 to 37.5 mg per day. This dose is commonly taken before breakfast or within 1 to 2 hours after having breakfast. If deemed necessary, the dosage might be adjusted upwards, but it’s of utmost importance to adhere diligently to the guidance provided by your healthcare professional.
On the other hand, the extended-release capsules of phentermine are usually consumed once daily, typically in the morning. The initial dosage for this formulation can either be 15 mg or 30 mg, as determined by your medical practitioner. It’s essential to keep in mind that these dosing recommendations should be followed under the supervision and instructions of your healthcare provider.
When you’re taking phentermine, a prescription medicine for weight loss, here are some important things to keep in mind: Firstly, follow your doctor’s instructions carefully. They’ll tell you how much to take and when. Eating a healthy diet is still paramount. Even though phentermine can help you eat less, make sure to choose foods that are good for your body.
Try to control your portion sizes. Even with phentermine’s decreased appetite, this will aid you in preventing overeating. Drinking enough water is a must. It’s good for your body and can also help manage your hunger. Exercise regularly. Moving your body can make the effects of phentermine even better. Just talk to your doctor before you start a new exercise routine. Make sure you’re getting enough sleep, around 7 to 9 hours every night.
Stay away from things that have a lot of caffeine or other stimulants. Phentermine itself is a stimulant, so adding more can be too much for your body. It’s best to limit alcohol while you’re on phentermine. Alcohol can mix with medicine and cause problems. Phentermine is usually not meant for long-term use. Your doctor can help you figure out what to do after you stop taking it. Don’t skip meals, even though you might not feel as hungry. Skipping meals can mess up your body’s rhythm.
Rather than chasing quick fixes or extreme diets, focusing on small, gradual changes can make a significant difference. Start by incorporating whole foods into your meals and finding physical activities you genuinely enjoy. It’s not about perfection, but about consistently making choices that nourish your body and mind. Developing a positive relationship with food and your body is key. Listen to your body’s cues of hunger and fullness, and allow yourself occasional treats without guilt. Seek support from friends, family, or professionals who understand your goals and can provide encouragement along the way.
