Reviews for Phentermine to treat Weight Loss

"I have lost about 30lbs, and gained muscles in the last 8 months while working out 3 days a week. The last 5 months I'm down about 20 inches also. I do have to take it by no later than 9am so that it doesn't affect my sleep. It's best to take this as soon as you wake up. If you take it later in the morning or noon it will mess with your sleep! The dry mouth issues went away for me around 3-4 months."

"I started taking this medicine on June 14th and I am down 5 lbs, with that comes dry mouth , bitter mouth night time , I can't sleep at all at night , seems like my eyes are closed but brain is running on fast pace. Other than that I eat right and exercise 5-6 days a week."

"I have been taking phentermine 37.5 since May 12th 2017. I am 5'5 and I started at 223lbs. Today is June 25th and now I weigh 201lb. So I have lost 22lbs so far. My side effects in the beginning were dry mouth and it literally felt like cotton was in my mouth it was so dry! I believe I experience a bit of moodiness too from time to time. Also I get really dizzy when standing up too quickly. I would definitely recommend getting in the habit of working out while taking the medicine because I have lost a good amount of weight and I don't work out. I am a server so I do stay in my feet but I do no other extra curricular activities, so I know it is only the meds that are allowing me to lose weight therefore I need to start exercising now!"

"I requested this medicine from my doctor for weight loss and they refused, saying they are not allowed to prescribe any type of Phentermine medication because it causes tachycardia and death. Anyone else have a doctor tell you that?"

"At my doctor's visit on May,21 2017 I was told I have a high blood pressue and high cholestrol and weight 171 lbs. I'm only 29yrs old and 5'3". I then told my doctor that I want to lose weight. She prescribed me phentermine 30mg, which I take Monday to Friday. After 2 weeks, I'm down to 161lb, lost 10 lbs. I'm excited to see my next result.I feel active and full of energy .My mouth gets dry most of the time so I always carry my water bottle with me. The bad thing about it that I noticed is I'm always mad all the time even with just little things.But...this thing works and I love the changes with my weight loss."

"Just started taking this three days ago I am back and fourth to the restroom I haven't weighed myself yet but I drink tons of water and only pee maybe three times a day. On this medicine I have no problem going to the restroom at all. I was 220 at my check up to get the pills so I'll keep u posted on my progress when I feel confident enough to buy a scale."

"I'm a 52 year old women, moderately active through golfing and walking, and a relatively healthy eater who never has dieted and didn't need to. Menopause, age, activity level and metabolism has each contributed to a 35-40 lbs weight gain. After a year of increased activity and reduction of calories and carbs such as pasta, potatoes and breads, I was not able to really maintain a 5-10lbs weight loss if I didn't walk at least 5 miles each day. I noticed there was an overall reduction in energy. My doctor had been on this journey with me; food journals to now Phen. 37.5 mg. In 12 days I've lost 8.6 lbs. I do have a dry mouth and a suppressed appetite which I hope over the 3 month prescription will help me to reduce portions considerably."

Adipex-P (phentermine): "I just started this medication on June 12 starting weight is 184 I am down to 179 already. My primary doctor advised that I do the name brand of the medication for the first month and than the following two months I have the choice of generic or name brand. Like most I have tried all the fad diets and pills and spent countless money on stuff that just did not work. Now Medical I have RLS (restless leg syndrome) and I have not had a problem with this medication effect the medication I take for that. Only real side effect I have seen so far is dry mouth even though I am drinking anywhere from 64oz water or more a day. I have increase energy which is great. I will update more results as they come. Also my insurance does cover some of the cost."

"I'm 5'7 and at a current weight of 209. I've been yo-yo dieting for several years, losing 20 - 30 lbs, gaining it back and then some the next year. My GW is 149 (60 lbs total). I started 37.5 mil of phentermine 3 days ago and am already down 4 lbs! The only side effects I've had, so far, are extreme thirst (which is good) and TONS of energy (which is great). Hasn't kept me up at night at all (other then the constant trips to the bathroom!) I am also exercising about an hour a day, either walking or some sort of cardio, and eating small, healthy, frequent meals throughout the day, which I have to remind myself to do since I have NO appetite. :)"

"I love the results of taking this prescription. My only issue was my mood swings while on them. I seemed to be mad a lot. So I started just taking half a pill and it only got a little better. That is the only reason I gave it a 9 and not a 10. It works, but the effects it has on my mood are not good."

"Hi. I have been on adipex 30 mg for almost a full week. I am 49 with high blood pressure, in menopause and recently diagnosed diabetic. My Dr put me on it because no matter what I do I can't seem to lose weight but keep gaining. When I eat healthy and exercise I do lose inches but no pounds. I am 5'7 and 202lbs. I have never been this big. I think I can see a difference but I am so afraid to get on the scale. My Dr has told me in the past I'm fighting an uphill battle. I have been skeptical and when I read of so many seeing such great results, I do not want to be devastated if I don't see any. My plan is to join a gym in the next couple of weeks as I am not good at exercising on my own."

Adipex-P (phentermine): "At 280 pounds, recently diagnosed with Type 2 Diabetes, and told to start medications, I turned to my doctor to discuss potential stomach procedures. Well, with 1 Kidney, I'm pretty certain Diabetes would eventually cut my life short so why not go through a drastic change? No.... instead I asked her for three months to lose 30 pounds, and she suggested I try Adipex/Phenermine 37.5mg So like many all of you, I did, and I instantly felt that sudden feel good surge of energy. I'm now 10 weeks in and lost 33.5 pounds. Some will read this and many of your posts and instantly think it's a fake review. But honestly readers, this pill has changed my outlook on life. Give it a shot, it may not work for all, but it may work for you!"

Fastin (phentermine): "This is my 3rd time using these pills. The first time was in 2012, I lost roughly 35 lbs. I started again about 2 months ago. I kept the weight off, for about 4 years then got too comfortable and gained weight so here I am. Along with everyone else, when I first took an entire pill I too thought I was going to die. LOL funny but not funny. I started breaking the pill in half & I had no more issues. I DO NOT recommend taking these pills on an empty stomach. Eat first, take with WATER no caffeinated beverages or juice. Drink at least 16 ounces of water with it and you more than likely will not have anymore side effects. I feel completely normal when taking the pill as mentioned above. Hope this helps!"

"I started 5/26/2017 on one 37.5 mg tablet daily, my starting weight was 220 lbs, and one week later I am down 10 lbs, I weighed myself this morning and I weighed 210! I had to completely cut out all simple carbs like bread, pasta, tortilla, and also absolutely no sweets which is my downfall but to be honest I have no interest in any of those foods because the results I am seeing are more addicting than the food! I stay under 1200 calories a day and I drink 1 gallon of water a day. The only side affect I have noticed is dry mouth, and when I workout really hard my heart rate did creep up to about 198 which freaked me out a little so I had to tone it down a bit on the run that day. I have also workout 5 days a wk. It's been worth it so far!"

"I started taking Phentermine 37.5 mg in April after I went to my doctor appointment and weighed 172 lbs. This was up 14 lbs in 1 year. I am 5 ft 7 in, 52 year old woman going through menopause. I absolutely flipped about how my weight keeps going up and my doctor suggested I try this a couple months. It has been a great success, on June 3 and I'm down to 159. Had a lot of side effects though. Besides the dry mouth, I have terrible insomnia, so bad I can only take like three days in a row then I need a break so I can sleep. Worse, I have been really cranky with my boyfriend and crying way more than normal. I still have 25 pills left, but I don't know if I'll take them. Will update later."

"After gaining 90lbs through the last 4 years of nursing school, my heaviest weight of 277lbs when I asked my MD for a px for Adipex. I started taking phentermine (Adipex) 37.5mg daily every AM on May 9th and weighed in at 267.2lbs May 17th, 266.1 May 25th, and 263.9 June 1st. I also do between 30-60min strength training/cardio 3-4 times/week at the gym. After my first week taking this px, I did find myself needing to pay more attention to eating small meals 5-6/day or the side effect of dizziness would occur. Dry mouth is also a side effect which I've noticed so I bring water with me everywhere to get my fluids in around 3200mL. I started taking half this dose the other day to decrease the dizziness which has been effective."

"I am 46 years old and 4'11". On April 4th I was 165 pounds, borderline diabetic with high blood pressure at my Dr. visit. He prescribed phentermine which I started taking on April 5th. Today I had my 2 month visit and I have lost 19.8 pounds total. My fasting blood sugar was down to 88 and my BP was down also. Hoping to lose another 8-10 before my appointment in July. Feeling great!!"

"I started taking phentermine 37.5mg on Feb 28, 2017. I am 5'7, and weighed 264 pounds at the time. I did not loose much due to me being inconsistent with taking the pills. Once I became consistent accurately, in March I lost a total of 11 pounds for the month. (253). In April, I was on a second refill, but someone stolen my pills, so I was not able to take anything for the month April. Refilled on May 13, 2017, weighed in at 258, I gained 5 pounds. On May 24th, two weeks after taking the pill I lost 8 pounds which put me down to 250. The main point of all this is to be consistent, with taking the phentermine, exercise, eat your protein, and drink water water water water. I drink a gallon of water daily. I hope this helps someone!"

"I'm 5'3" and last year I was at my heaviest of 267. I started on phentermine last year for 3 months and l lost a total of 38 pounds. I kind of fell off the band wagon of going in each month for a new prescription and how busy my life got and ended up gaining 13 lbs back in a year. But ready to get back on the band wagon and go for at least another 38 pounds if not more."
