For Weight Loss (Obesity/Overweight) "I started Lomaira (phentermine) on 8/13/20. I'm 5'10 and my weight was at an all-time high of 218 when I started. My doctor had me start with a half dose (4mg) and half dose of Topiramate (generic Topamax -12.5mg) for two weeks. Then I will move to a full dose of each for the rest of the prescription. I have been drinking a gallon of water a day, eating a low-calorie diet, and doing light exercise daily. My appetite is controlled, my energy is up, and my system is cleansed. I have lost 10 lbs in one week. I do need to take it earlier in the morning because it's hard to fall asleep. But I'm looking forward to feeling like myself again. Best of luck to all of you!"

For Weight Loss (Obesity/Overweight) "For years, I struggled to drop the extra weight I put on after having my second child. I tried everything from online programs to workout DVDs, but I always hit a plateau. When my doctor recommended Lomaira, I was honestly pretty skeptical. But two and a half months later, I’m down nearly 10 pounds, and it actually feels like it’s sticking this time. I started at 168 pounds, hoping to get down to 150. One 8 mg pill a day has seriously helped cut my late-night munchies and sugar cravings. Surprisingly, I haven’t felt jittery or had trouble sleeping, which was my biggest concern with a stimulant. Instead, I’ve got more energy, which is a huge help when you’re juggling kids and a busy schedule. I still have a bit more to lose, but I’m really happy with how far I’ve come. If you’ve been stuck in the same frustrating cycle, it might be worth talking to your healthcare provider about Lomaira. It’s done wonders for me, and I finally feel like I’m on the right track."

For Weight Loss (Obesity/Overweight) "This is the low dose (8 mg) Phentermine that is theoretically designed to be taken up to three times per day. Years ago, I took the full strength 37.5 mg Phentermine and felt like I was going to die and couldn’t sleep. This low dose for me is totally different. I still feel a little “wired,” but my blood pressure and heart rate are normal, and if I don’t take it too late, I can sleep okay (although I have honestly had sleep problems anyway, so I can’t evaluate that well). This dosage is way lower, so you will have to be more careful with what you eat. You will have to take it at least twice per day (maybe three if it doesn’t bother your sleep and you have a lot of weight to lose). I really am glad doctors discovered that lower dose Phentermine works pretty well because I just couldn’t tolerate the side effects of the higher dose, but this lower dose is doable. Drink lots of water and do NOT drink caffeine or take other stimulants on this."

For Weight Loss (Obesity/Overweight) "I do have ADD, and this is a low-grade amphetamine, so for someone who doesn’t have ADD, these may work. I am not sure why my doctor chose to put me on these, as they do the complete opposite for me. Since I do have ADD, they stabilize me rather than stimulate. The side effects include insomnia, high BP, lower appetite, and boost energy. I am not a person who naps, I can run on 5 hours of sleep, and these made me SO TIRED after taking them. They didn’t give me high BP, they didn’t cause insomnia, they didn’t give me energy, and they did not lower my appetite. They did give me brain fog. You’re apparently supposed to lose 2 lbs per week on these pills. My doctor had me on one 8 mg tablet, then wanted to bump it up to one and a half. I did not continue the meds because even after a month, change in diet, and consistent working out and walking, they still did nothing for me. I started these at 226 and have actually been fluctuating between 237-230 since taking them. I do not recommend."

For Weight Loss (Obesity/Overweight) "I'm a 6'2", 47-year-old overweight female. Like everyone else that is overweight, I have tried everything on the market! I started using Lomaira 2 weeks ago after my doctor recommended it to me. Previously on Phentermine 37.5 mg tablet, she thought maybe it would help to curb my appetite since I take these 3 times a day. Problem #1: it made me super constipated! I ended up in the hospital last week with severe stomach pain. My X-ray showed my colon was packed full. Problem #2: It kept me wide awake at night!! I would try to go to bed around 8-9 pm and would be back out of bed by 10 and wide awake until 4 am... complete insomnia! Problem #3: it never curbed my appetite, in fact, I ate worse taking Lomaira than with the Phentermine. Weight loss pills aren't for me, I guess! Good luck to everyone that is having success with this drug! I envy you!"

For Weight Loss (Obesity/Overweight) "Started out at 392 lb on 7/21/2017, and I'm 6'2. So far, I don't think it's doing a good job. I feel energetic, but my appetite is still ferocious. Insomnia isn't a problem. Will update when I reach my first full week."
