So, how do you know what’s true and what’s not? Here we’ve debunked a few of the most common phentermine myths and misunderstandings! 1. You can buy phentermine without a prescription.FALSE! One of the most common myths about phentermine is that you can purchase “real” (prescription) phentermine online or without a doctor’s prescription. This isn’t true. The active ingredient in prescription phentermine is phentermine HCl: a chemical compound similar to amphetamines. Given the chemical’s strength and addictive potential, it is classified as a controlled substance by the FDA. For that reason, “real” phentermine is NOT available online or without a prescription. The only legal way to get phentermine is via consult and prescription from a licensed and practicing physician. If you are looking for something that you can buy online without a prescription, consider dietary supplements. Among the many options on the market, phentermine.com officially recommends Phen Caps to help suppress appetite and boost energy, without the added side effects.2. Phentermine doesn’t have many side effects.FALSE! Some people hear about phentermine from a friend or coworker and assume it is a “casual” weight loss pill with few or no side effects. This could not be farther from the truth. Phentermine is phenomenally effective, but also carries the risk of some serious side effects.These serious reactions include heart and lung problems, and typically present as chest pain, shortness of breath, fainting, swelling (edema) in the legs or feet, or difficulty in carrying-out daily activities. If you experience any of these symptoms, you should contact your doctor or call emergency services immediately.However, most users will experience only minor reactions. Common side effects include dry mouth (xerostomia), trouble sleeping (insomnia), headache, constipation, rapid heartbeat, dizziness, “phen rage” (dysphoria) and change in libido. Check out the links above to learn more about each side effect and how to cope.3. You can take phentermine forever.FALSE! Phentermine is a short-term weight loss aid, not a long-term prescription. The FDA approval for this medication is for twelve weeks (three months). The short-term nature of this approval is related to the toll it takes on your body and heart, its addictive nature and users’ tendency to develop tolerance. So, the maximum prescription is typically three months. If your doctor feels that you would benefit from a longer course of treatment, he or she may evaluate the possibility of prescribing multiple rounds of phentermine, usually with breaks of at least one month between courses. This repetition is solely at the discretion of the prescribing doctor and should be carefully evaluated on an individual basis.4. Phentermine is designed to help you lose weight without changing your diet.FALSE! Phentermine is intended to help suppress your appetite and boost your energy, while giving you the chance to make-over your daily habits. Take advantage of these effects to learn about healthier eating and make sustainable changes to your diet.First and foremost: keep an eye on portions. Aim to fill half your plate with fruits or veggies, one quarter of the plate with lean protein, and one quarter of the plate with whole-grain starches. If your appetite is very small, you may also need to focus on eating enough. Women need at least 1200 calories per day, and men 1500 calories per day. Finally, prioritize hydration on phentermine! Drinking enough water helps you lose weight, process toxins, and stay in balance. While phentermine gives you a boost, it’s important to stay conscientious of these changes if you want to lose the weight and keep it off.5. You don’t need to exercise while taking phentermine.FALSE! One common phentermine myth, especially in support groups and forums, is that you don’t need to exercise while on phentermine. Barring any restrictions from your doctor or medical team, exercise is a healthy part of your weight loss journey. If you haven’t been exercising much lately, make sure to start slow. It’s not worth it to go all-out from the start and risk injury or burnout! Once you get going, aim for 30-60 minutes of activity per day, including both cardio and strength training.

You will lose weight instantly and never plateau on phentermine.FALSE! Many phentermine users think they will lose massive amounts of weight instantly, and then keep losing at this impressive rate for the duration of their prescription. Unfortunately, this expectation is neither accurate nor realistic.Safe, sustainable weight loss is usually considered a rate of about one to two pounds per week. These are general numbers, so you may lose a little faster with phentermine (especially at first). Still, it is likely that the as your prescription wears on, the effects of the phentermine will lessen. Your body’s increased tolerance to the medication may manifest itself as an increase in appetite, decrease in weight loss, or a combination of the two. Some people find that adding Phen Caps can help boost weight loss in these later stages of their prescription. Still, phentermine’s decreasing effectiveness, combined with the fact that it is only a short-term prescription, necessitate the development of healthy habits throughout the course of your treatment.7. Everyone gains the weight back when they stop taking phentermine.FALSE! Many phentermine users worry that they will gain all of the weight back as soon as they stop the meds. While it is far from guaranteed, rebound weight gain is possible if you don’t stay committed to your new healthier lifestyle. Weight maintenance ultimately depends on you and your dedication to healthy habits. Since phentermine is a short-term prescription and not intended as a long-term solution, it’s very important that you don’t rely too heavily on the medication to make the change. Instead, use your time on phentermine to establish healthy, sustainable eating and exercise habits, and then make it a point to stick to them once the prescription finishes.8. You can’t take phentermine and birth control together.FALSE! If you can become pregnant, it’s important to use some form of contraception while taking phentermine. This weight loss medication is not suitable for women who are pregnant or trying to become pregnant. Understandably then, some women worry about the interaction between phentermine and birth control pills.Phentermine alone has not been shown to affect the effectiveness of birth control pills, but it has been linked to breakthrough bleeding in some cases. This unusual flow may be related to an increased need for estrogen while on phentermine. Qsymia (phentermine + topiramate) may decrease the effectiveness of birth control pills and/or cause spotting, so you should always use back-up contraception (like condoms).Regardless of your prescription, it’s important to speak with your doctor about birth control and phentermine at the initial consult. That appointment is your opportunity to address any concerns or potential problems ahead of time. Similarly, if any issues arise while you are taking phentermine (or you notice anything unusual), don’t be shy about contacting your doctor to ask about it!9. Phentermine is a good option for everyone, and anyone can get a prescription for it.FALSE! As we mentioned above, phentermine is a serious medication and should not be casually prescribed. It is intended for the short-term treatment of exogenous obesity, not to help people lose “a little bit” of extra weight. The most general guidelines recommend phentermine for otherwise-healthy people with a BMI >30, or those with a BMI >27 plus another risk factor such as diabetes or controlled high blood pressure.Phentermine is not recommended for people at normal weight (or just slightly overweight), nor those with any history of cardiovascular problems. Your doctor and pharmacist should also check to make sure you do not take any contraindicated medications, or suffer from other conditions that rule-out phentermine. It is very important that you disclose all medical history and all medications to the prescribing doctor when considering phentermine.If your doctor won’t prescribe you phentermine, he or she probably has your best interests at heart. Losing weight is important, but your overall health and well-being is the paramount concern. Instead, consider trying a non-prescription phentermine alternative like Phen Caps.10. Phentermine is a miracle pill.FALSE! Phentermine can work wonders, but it is not a miracle pill. Weight loss takes hard work, dedication, and commitment to your goals. If phentermine is right for you, take advantage your time on of this medication to develop healthy habits. Learn to make healthier choices at meal times, establish a sustainable workout routine and improve your lifestyle overall. Phentermine will give you the first push, but it’s up to you to make the real weight loss happen. We hope this helps clear up the confusion surrounding some of the most common phentermine myths!
