Phentermine Q&A

Phentermine Hydrochloride is a prescription medication used as an appetite suppressant. It is classified as a controlled substance and can only be obtained through a doctor filled prescription at a pharmacy.



Phentermine works by binding to receptors located in the hypothalamus. There are two major areas on the hypothalamus that control hunger, and this drug helps those areas of the brain to “think” that the stomach is full. Phentermine is generally prescribed to patients with a higher BMI (body mass index) score to prevent over eating and help them lose weight. In some cases, this drug is prescribed to people requiring rapid weight loss. One such case is individuals who are interested in undergoing a gastric bypass procedure. If the patient is not qualified for this surgery due to excessive weight, Phentermine can be prescribed ahead of the procedure to help the individual get to a safer weight to go under the knife. In other instances, if weight is dangerously impacting an individual’s health, doctors may prescribe Phentermine to ensure the patient is able to more quickly lose the weight necessary to improve overall health. On average, people lose at least one pound of weight per week while taking Phentermine 37.5. If, for some reason, you feel something out of ordinary such as adverse side effects or if you fail to lose weight, Phentermine might not be working for you, and you should address these issues with a healthcare professional.

Why is Phentermine only available by prescription?

There is worldwide ban on the trade of non-prescription Phentermine. In the United States, it is a schedule IV controlled substance. According to the United States Food and Drug Administration, any type of trade without a medical doctor’s authorization is considered illegal. It is even illegal to share and/or sell Phentermine pills to your friends, relatives, co-workers, or anybody you know. If you are caught in possession of non-prescription Phentermine, it is a felony that is punishable on the same level as illegal narcotics. If you give someone Phentermine and they face any kind of health complications, you may be looking at even greater legal problems. Under any circumstances, do not share your prescription Phentermine with anyone.

How to get a Phentermine prescription?

Healthy individuals who are having problems with extra weight and/or obesity should be able to get a prescription to Phentermine through a physician. If you think this medication can help you improve your overall health, it may be worthwhile to mention it to your doctor. Any primary care physician will know how to properly assess your specific needs to determine whether or not this drug is a safe and viable option for you. You will be asked to visit the doctor’s office for an appointment to be evaluated even if you’ve had a recent physical. Your doctor is not authorized to prescribe Phentermine remotely. Health checks will most likely include a blood test, heart and blood pressure exam, and a review of any medications, vitamins, and supplements you are currently taking. If test results come back and everything looks normal, you will most likely be given a prescription for a one month supply of Phentermine 37.5. Doctors are not authorized to prescribe more than one month of phentermine per patient per month. Subsequent monthly visits and health evaluations are required to continue the prescription for the maximum twelve week recommendation for this drug. Doctors who do not follow medical legislation when prescribing Phentermine may face a loss of their license to practice medicine and possible jail time, as seen with a recent incident involving Dr. Pynkerton Newton of Indianapolis, IN as well as many others. If you are just starting a Phentermine diet plan, you will most likely be prescribed a 15 mg dosage, most often taken in the morning either before or after a healthy and well rounded breakfast. In some cases you will be asked to take 7.5 mg twice a day if the 15 mg dosage is too much for you. As with many medicines, particularly stimulants, you may build a tolerance to Phentermine, and at some point this lower dosage may not be as effective as before. At this time, your doctor will likely up your dosage to a traditional 37.5 mg per day. This is the highest daily dosage approved for use by the United States Food and Drug Administration. In Australia, Duromine can come with a 40 mg daily dose.

How old do I have to be to get Phentermine?

When it comes to Phentermine, there are no age restrictions as with alcohol or tobacco. Restrictions may be applied on case by case basis. In some instances, even children receive Phentermine prescriptions but with a lower dosage to prevent developmental issues. Phentermine can be prescribed to individuals of any age so long as there are no adverse reactions to their body or overall health. Blood pressure medication as well as other various prescription medicines are two major deciding factors for access to a Phentermine prescription.

Is Phentermine Addictive?

Absolutely – Phentermine is addictive. Any type of abuse and/or other misuse may lead to mental and/or physical addiction to this substance. If you miss the dose, do not take a double dose the next day. Not only may you harm yourself by consuming excessive amount of Phentermine, you can also become resistant to smaller dosages very quickly with this drug. Taking extra Phentermine will not improve your chances to lose weight more quickly. Always follow directions on the prescription given by the health care professional. Do not try unconventional methods of consumption with Phentermine, such as snorting or injecting. You may have irreversible consequences if you do not follow your doctor’s recommendations.

What's the difference between brand name and generic Phentermine?

There many various Phentermine manufacturers and distributors worldwide. Some are simply filling capsules with Phentermine Hydrochloride and selling it at the local pharmacies as generic (non-branded) Phentermine. There also Phentermine makers that are offering branded products. The main differences include release mechanism or addition of inactive ingredients. For example, in the United States, there are two major brands of Phentermine diet pills. One is Vivus’s Qsymia. This is a combination drug that also contains Topiramate to help with the intense cravings that can come along with a decrease in daily caloric intake.  Another is Adipex P that offers its own proprietary release mechanism. Both branded products have been shown to be effective, and your doctor will be able to prescribe the best medication for your specific needs. There is also a difference in price. For example, generic Phentermine can cost anywhere between $20 to $50 per one month supply. The price of generic forms depends on the pharmacy where you get your prescription filled as well as the amount of milligrams per capsule or tablet.  The highest price for generic Phentermine in the United States should not be greater than $50 per one month supply. If you are purchasing Adipex P or Qsymia, you are generally looking at a higher cost. One bottle of Adipex P can range from $100 to $300, and Qsymia can cost between $300 and $500 per bottle. The cost is 100% out of pocket as no insurance company covers Phentermine diet pills.

How much weight can I lose on Phentermine and why I am getting fat?

The amount of weight you can lose with Phentermine depends on several factors. Some of these major factors include metabolism, eating habits, amount of physical activity, overall health, and other medications, vitamins, and supplements you are taking. For example, people with hypothermia may not take as much Phentermine as healthy individuals. People with diabetes may have sugar spikes as a Phentermine side effect. Patients who take other medications can suffer an adverse reaction with Phentermine and it can be rendered ineffective. The most important factors are eating and staying physically active. You absolutely must follow proper diet and exercise regularly while taking Phentermine. At the very least you should be able to lose one pound per week. If that is not the case, you may want to stop Phentermine use and consult a doctor. Always remember that a full spectrum of essential vitamins and nutrients should be consumed daily. While you are dieting, you might not get enough nutrients and you may experience adverse effects rather than benefits. It may be a good idea to consume vitamins and nutrients from sources other than food. Ask your doctor which multivitamins and supplements you should consume daily in order to maintain optimum health. In order to physically function the average human body requires about 2000 calories per day. The formula is simple: if you consume less than 2000 calories in one day,  your body is programmed to “borrow” nutrients stored in fat cells. The human body is programmed to convert sugar into fat and store that fat for the future. When you exercise, you end up “burning” additional calories, which will result in more fat being “borrowed” from these fat deposits. Every human is born with hundreds of millions of fat cells designed for storage of fat so that body has enough energy to function if lacking the proper amount of sustenance. These cells are designed to fill up with fat and can grow to 1000 times its original size. When a fat cell reaches its capacity it clones another empty cell and so on. This is how people become overweight. These cells gets filled up, similar to water balloons and then multiply. Most foods you eat are converted into sugar for absorption. Food that comes with a higher glycemic index creates these “sugar spikes,” and any excessive amounts of sugar eventually convert into fat. Food that is high in carbohydrates generate these spikes, then the pancreas releases extra insulin for proper absorption. Any type of food with a high glycemic index should be avoided at all costs. Fiber is a must with every meal. It slows down the absorption of sugar and prevents these spikes. Always remember, if you don’t consume enough fiber you are looking at higher insulin levels that will eventually become fat. Stay as far as you can from “empty calories.” Soda is one major cause of weight gain. Alcohol, especially beer, should be avoided while you are dieting. Obviously anything deep fried, potatoes, burgers, any kind of fast food, as well as any other high fat or sugary foods should be forgotten. Approaching every eating decision with consciousness and discipline should get you the desired results – health and weight loss!

What type of side effects do people experience while taking Phentermine?

Phentermine side effects are similar to other stimulant based medications. You may experience nausea, headache, stomach cramps, and insomnia as mild side effects. More severe side effects may include vomiting, fainting, memory loss, erectile dysfunction, addiction, as well as other health complications. In the case of experiencing mild side effects, you should contact your healthcare professional to let them know about how you feel. If, for some reason, you are experiencing something more do not hesitate to call 911 immediately. If you are concerned about how you feel while taking Phentermine, stop use and consult with your physician to ensure that you are not putting your health at risk.

Where can I find Phentermine coupons?

Often times, either brand name manufacturers or local pharmacies issue coupons to buy Phentermine. Normally these coupons are issued due to over stock or low demand seasons. Summertime and winter holidays are optimal time frames to get to get cheaper Phentermine. During summer and winter the weight loss industry suffers, because people are not as concerned about weight loss during these periods. When people become more concerned about their weight, normally after New Year’s Day, prices can skyrocket, and it might be more expensive to purchase Phentermine during that time. So, if you plan your New Year’s resolution to lose weight, it may be better to get your supply before Christmas and begin taking it after New Year’s. You can save as much as 50% that way. Best of luck to you on your weight loss journey! You can do it!
