Phentermine FAQ

Phentermine is known to be the oldest and the safest weight loss pills there is. However, after being in the market for more than 60 years, lots have happened. This drug has been counterfeited, copied, and experimented upon more times than you can imagine. After all those, it’s natural that people have formed many opinions and spread many rumors about it. Some may be true, and some are false. Here at E-Medz Solution, we’ll take deep dive and, once and for all, end the speculations. It’s a collection of 20 frequently asked questions and answers about Phentermine– the truths, the myths, and the in-betweens. This will be an extensive review for those who are genuinely interested in learning about this drug.

20 Phentermine FAQ:

1. What is Phentermine?

Phentermine is an acidic salt form known as Phentermine Hydrochloride, which is an appetite suppressant. In addition, it stimulates the body to increase metabolism and burn calories. Doctors usually prescribe it with diet and exercise to treat obesity, high cholesterol, and other weight-related conditions. FDA approved it as a weight loss pill in 1959. Since then, there have been several other weight loss pills, but Phentermine still stands the superior and commands 80% of the weight loss product market.

2. How does Phentermine Work?

Phentermine works by increasing the level of 3 specific neurotransmitters: Norepinephrine, Serotonin, and Dopamine. All these naturally occur in the body, but for some people (for whatever reason) the flow levels could be lower than normal. They seem to gain weight faster than others. Phentermine tends to solve those problems. Following are the specific descriptions of what they do to the body:

  • Norepinephrine or Epinephrine: People know it as Adrenalin or Epi. It is a metabolizer. An increase in the level of Epi tells the brain to request more energy. It is actually a stress hormone and prepares the body for a ‘fight-or-flight’ response. The body then reacts to it by burning fatty cells to release energy.
  • Serotonin: Serotonin is a versatile hormone. Of its many functions, one is the control of the digestive tract. It signals the brain when we are full. We’d continuously eat if it wasn’t for Serotonin. This is the appetite suppressant.
  • Dopamine: It’s the reward hormone. A huge amount of Dopamine is released after sex. It tells the brain to relax and gives us a happy feeling. The release of this neurotransmitter is necessary for two reasons. Firstly, the release of Adrenalin can stress the body, and people might have anxiety or panic attacks due to the ‘fight-or-flight’ response. Dopamine is there to tell the brain that ‘Everything is fine’. Secondly, a short-term stress response is good so that our body releases energy. Long-term stress has the opposite effect. Our body has a built-in defense mechanism that conserves energy to be used later. If the stress lasts long, the body starts to conserve energy instead of releasing it. That means that you can even gain more weight in the long run. That’s the reason people eat more while under stress. Dopamine controls it so that Serotonin and Norepinephrine can do their jobs.

3. What are the Available Dosages?

There are several dosages available in the market. They range from 8mg to 37.5mg. 8-15mg is designed for young adults. Adults can also use those lower dosages just to test if their body is adjusting to the drug. A doctor or a dietitian will know better, so it’s always a good idea to consult one beforehand.

The most common dosage for an average adult is the 37.5mg version. This is the original Phentermine or k25 pill.

4. How Should I Take It?

It is an oral medication in tablet or capsule forms so you should take it by mouth with water. Normally a person should take 2 pills a day for a 30 day period. After that, they should stop and assess. If it’s not the desired weight level, they should take a 10-day break before resuming for another 30 days.

Note: It’s very important to follow these recommendations. Your dietitian will also say the same thing. The explanation is coming later.

5. What are Phentermine Brands?

The original patented Phentermine HCL was manufactured by Vivus Pharmaceuticals in 1959. After the expiration of the patent, many other companies produce it in different names. In the USA, KVK Tech manufactures in the same name ‘Phentermine HCL’. This is also known as the K25 pills. The most popular, however, is Adipex-P by Teva Pharmaceuticals.

Both look almost the same. These are white oval-shaped pills with blue dots. K25 has the letters ‘K’ and the number ’25’ inscribed on one side. Adipex-P has the marking ’50-30′.

It’s also sold under several other names such as Ionamin, Duromine, Fastin, etc, but they’re not that popular in the market.

6. How should I take Phentermine for the Best Results?

Consult a doctor, dietitian, or nutritionist before starting a course. They can help determine the dosages based on your current weight, age, and some other factors. In general, an average adult should take 2 Phentermine 37.5mg a day in the earlier parts of the day. It is a stimulant so if someone takes it in the evening, it can cause insomnia.

As mentioned earlier, it’s good for a 30 day period only. Remember that all weight loss pills can weaken the body over time due to the low appetite and high metabolism. That’s why it’s important to give it a break. If the weight is not at an ideal level, you can resume for another 30 days after a 10-day pause. It’s required so that the body has the time to recover. It also helps deal with the addiction issue, which we will discuss later.

This recommendation is valid considering that the patient is only overweight and needs to lose some. There’s no need for additional attention to food and exercise. Phentermine will do the job on its own. You should at least have two healthy meals a day.

For those who suffer from obesity, which is a serious medical condition, the prescription is totally different. They might be required to take 3-4 pills a day and it has to include proper diet and exercise under medical supervision. Remember that obesity can cause heart problems and the release of Adrenalin, which elevates heart rates to burn calories, can do more harm than good. Doctors often put the patient under a strict diet and administer more Dopamine releasing agents to keep the heart rate down.

7. How Much Weight Can I Lose Using Phentermine?

It depends on the patients’ age, normal metabolism rate, work, lifestyle, and several other factors. This is quite hard to say. However, if someone is an average adult with an office job who takes at least two solid meals a day, they can expect 2 Kgs or 4.40 lbs a month (30 day period). It is quite good. Never try to lose weight super fast. It’s outright damaging to your overall health.

8. Where can I buy Phentermine without a Prescription?

Phentermine is not an OTC drug in the USA or UK. Thus, you need a valid prescription. Nevertheless, it is available in many other countries. Therefore, consumers in the USA or UK tend to look for online pharmacies located outside the country. It’s fine as long as you have found a reliable pharmacy. The pharmacy must have a discreet packaging system so that the delivery arrives safely. We also know of a few online pharmacies that can deliver genuine Adipex-P to your door.

9. How Much Does Phentermine Cost?

At a regular pharmacy, it can be quite expensive. If you do have a prescription and your insurance covers it, you are golden. For those without prescriptions, online pharmacies offer a price of $2.95 to $3.50 USD. Now, there are cheaper ones also. However, we wouldn’t recommend them because there is a good chance that those are fake. We mentioned earlier that there are counterfeits for this drug. Weight loss products are always in high demand and competition is tough.

10. Is Phentermine a Scheduled Drug?

In the USA, it is a Schedule IV (low abuse potential) drug according to the DEA. The UK also follows the same restrictions, so yes, it is a scheduled drug. However, Schedule IV really means that the addiction potential is really really low. We’ll talk about it in another question later in this FAQ.

If you intend to order Phentermine online, just make sure that the pharmacy offers ‘Discreet Packaging’. It means that they remove the medication from the original blisters and repack them in airtight zip locks. Then they wrap it in several layers of carbon paper that help avoid customs detection.

After it has been delivered, you should store the pills in an unmarked container so that no one knows what’s in it unless they bring the pills to the labs. This way, you are safe from the law. This advice is for the people in the USA and UK. People in Canada, France, Spain, Italy, Norway, Sweden, and many other EU countries need not worry.

11. Is Phentermine Addictive?

Now, we’re getting into the ‘Phentermine Rumor’ parts. Anything is addictive if you take it for a long time on a regular basis. Our body simply expects it. We’re addicted to sugar, coffee, nicotine, and many other things for the same reason. A long-term vegetarian can get into trouble by eating meat suddenly. Why? The body doesn’t expect it.

Phentermine is not as addictive as many believe. Princeton University had a survey on over 10,000 participants in 2010 but found no solid evidence of addiction. Yet, since it is a stimulant, and it releases Dopamine (the feel-good hormone), some people may crave it after stopping. That’s why it has been scheduled IV.

If you follow the recommended procedure (30-day course with 10-day break), there is almost no possibility for addiction. That’s the 10-day break for. It allows the body to recover from the increased hormone levels. And I’m telling you from personal experience. I have used it for more than 6 months with no ill effects.

You may have heard a lot about how it became really addictive and people had to try really hard to recover from it with additional therapy and rehab. Those are mostly PR stunts done by other weight loss companies in order to downgrade Phentermine to get ahead. The weight loss product market is highly competitive. Just do a Google searchWeight Loss Products‘, and you will see millions of different products, advice, opinions, and stuff.

Although some may be right and indeed got addicted, but that’s only because they took it for more than 3 months without the recommended breaks. Yes, you can get addicted that way- no doubt.

12. Is Phentermine the Same as Fen-Phen?

This is another of those rumors that make people afraid of Phentermine. Yes, Fen-Phen came a lot after Phentermine HCL. FDA approved it in 1997. However, it contained Phentermine and another suppressant named Dexfenfluramine. It was thought that the combination would work a lot better since Dexfenfluramine helped release a few other hormones in addition to the original three. However, complex reactions to the drug started to affect the heart valves. After 24 fatalities, FDA revoked the approval and it was pulled out of the market.

Simplicity is beauty. That’s why plain and simple Phentermine is safe to take. Yet, people got scared since it still carries the name ‘Phen’.

13. What’s the Difference Between Phentermine and Adderall?

This is indeed a good question. Both Adderall and Phentermine derive from amphetamine. However, as illustrated below, the chemical structures are slightly different.

Difference between Adderall and Phentermine

What that means for you is Phentermine is a mild stimulant, an appetite suppressor, and a digestive tract manager. It releases the three hormones (Norepinephrine, Serotonin, and Dopamine), and the level of stimulation is quite low.

Adderall, on the other hand, releases only two (Norepinephrine and Dopamine) at much higher levels. Adderall is designed for more stimulation. It gives you focus and it’s very good at treating a mental condition called ADHD.

In short, Adderall is a stronger stimulant that has a side effect of weight loss (burning calories). Yet, since there is no Serotonin, you may experience constipation. On the other hand, Phentermine is a mild stimulant with the purpose of appetite suppression, and due to the release of Serotonin, you have a regular bowel movement. You can say that Adderall’s side-effect is Phentermine’s primary purpose, and vice-versa.

14. What are the Side-Effects of Phentermine?

All medications carry the possibilities of some side-effects and Phentermine is no exception. The side effects may include:

  • Dry Mouth
  • Nausea
  • Vomiting
  • Blur Vision
  • Weakness
  • Insomnia
  • Joint Pain
  • Headache

Since it’s a stimulant, dry mouth is quite common, and there’s nothing to worry about. After all, you are trying to lose weight, and the first thing a dietitian will tell you is to drink a lot of water so dry mouth basically works to the benefit. You’d want to drink more but stay away from sugary drinks and beer.

Nausea and Vomiting can occur at the very beginning as your body isn’t really used to appetite suppression. If it’s too uncomfortable, lower the dosage to 8mg or 15mg and let your body adjust. If not, they’ll go away in two to three days.

The others like joint pain, weakness, etc. have to do with proper meals and sleep. The stimulating nature of Phentermine may not let you sleep if you take it in the latter parts of the day. If you don’t sleep well, weakness, headache, blur vision, and joint pain ensue. That’s why the advice is to take them early and never take them in the evening.

Of course, consult a doctor if any of those side-effects become too intense to bear. You may be allergic to Phentermine HCL.

15. What are the Precautions before Taking Phentermine?

And I can’t stress enough that you should always consult a weight-loss professional before you start a course. Yes, you can buy Phentermine online without prescriptions, but it doesn’t hurt to assess your condition. Take into consideration your height, weight, lifestyle, eating habits, and heart condition before you take Phentermine. This will help create a program on how long the treatment should be. You don’t want to have to take it for the rest of your life.

If you have a history of substance abuse, let your doctor know. It can cause some problems in the long run. Diabetic patients need to adjust their insulin intake while using Phentermine so definitely seek medical advice. Patients with heart conditions should do the same although if the heart condition is caused by fat or cholesterol, Phentermine is the medication. Still, why risk it?

Pregnant women should not take it at all. It can cause low birth weight and premature birth. Breastfeeding mothers should not take it either as it passes through breast milk and can expose the infant.

16. What Happens if I Stop Taking Phentermine?

Nothing happens if you follow the 30-day/ 10-day rule. However, if you have used it for a long time (3 months or more) without a break, and you develop some kind of dependency, you should probably consult a doctor and slowly lower the dosages instead of stopping suddenly.

17. What Should I Eat While Taking Phentermine?

As mentioned earlier, unless a patient is suffering from obesity, there is nothing special that you have to do. Although you can add some protein-rich and high-fiber diet if you take your weight loss seriously. The general advice for weight loss:

  • Drink a lot of water
  • Eat more fruits and vegetables
  • Eat lean protein
  • Don’t miss a meal
  • Avoid alcohol
  • Sleep well
  • Exercise

18. What Other Drugs Interact with or Counteract Phentermine?

Very few drugs do. It’s relatively safe. Yet, antidepressants and sleeping pills can counteract a stimulant. There would be too much Dopamine and can cause addiction. Additionally, it can make a person weak and lazy.

However, sleeping pills like Zolpidem may be prescribed together with it as Phentermine may cause insomnia. The trick is not to take them together. Take Phentermine in the earlier parts of the day and take one Zolpidem an hour before bedtime.

19. Why is Phentermine the Best Weight Loss Pill?

Well, because it is the perfect combination. It releases three natural hormones and lets the body do the job. With Phentermine, you can expect full energy all day long, reduce cravings for too much food, and have a regular bowel movement. That’s all you need in order to lose weight efficiently. Just don’t overdo it and let it naturally burn your fat away.

Besides, we live a very busy life. Do you really have the time to count calories of everything you eat or follow a 25 step weight-loss method?

20. Do Celebrities Take Phentermine?

Absolutely 100% YES. They won’t admit it publicly though. How do you think they keep in shape despite their busy schedules? A regular diet and exercise regimen requires a proper routine, which is impossible if you are a celebrity. Some shooting can be in the day time, and some are at night. On some weekends you are busy and on others, you are free. There is no way a celebrity with a good body doesn’t take supplements to maintain their shape. Their body is their money maker. Kylie Jenner, Tom Cruise, Taylor Swift, and Paris Hilton are among the few known to use Phentermine.

    Thanks for the reminder that I will need to keep track of my water intake when taking phentermine pills. I’m currently looking for online phentermine pill sales because I’d like to stay home as much as possible due to the pandemic. Hopefully, their packaging and delivery would also be very sanitized.
