For Weight Loss (Obesity/Overweight) "I have been taking 10 mg since Nov. 5, 2009. I have gone from 203 to 177. I went off for two weeks this past month, and I have not gained but have stayed the same. During my time off, however, I had times of high anxiety and irritability, especially when starting the medication again. My blood pressure and pulse rate have been fine. I have had some constipation problems. I think my Dr. will raise my dose to 15 mg at my next appointment. My goal weight is 150. I feel so much better. It has helped with mild depression as well. Good luck."

For Weight Loss (Obesity/Overweight) "I have been on Meridia for almost a week now. I have not weighed myself due to the fact I hate the scale. The drug took effect after about 2 days where I can honestly say that my cravings/snack sessions have ceased, I have begun to try portion control, and it seems to work (where I am satisfied with a lot less). I am not constipated, and I do feel like I have more energy, but I'm still able to get a decent night's sleep. I notice if I exercise (even if I don't feel like it), I get energy. My blood pressure is fine thus far, but I will continue to monitor it as I progress. No headaches or breakthrough bleeding, no stomach aches. I have a slight lower backache, but that may be due to the sit-ups being done improperly."

For Weight Loss (Obesity/Overweight) "I LOVE THIS MEDICATION! I first started out on 10 mg and felt as if nothing was happening. I talked to my doctor and explained to her the situation, and then she prescribed 15 mg for me. 12 pounds in a week! I am feeling more motivated than ever to lose weight. Some side effects I have had are hunger, headaches, nausea, and some constipation."

For Weight Loss (Obesity/Overweight) "I started taking Meridia 3 weeks ago. In the first week, I lost 6 lbs, but I totally cut out all major carbs, e.g., bread, rice, fries. It definitely got me in the right frame of mind to eat better. Since it is not cheap, I was determined to go through with it. Yes, it works if you're determined. Side effects: terrible taste in mouth (can live with that). Constipation - a little concerning, but when it got bad, I skipped taking the drug for a couple of days, and it would be normal. Another concerning side effect that is listed is blood in the stool or bad period pains. I have not had a period in 4 years and got one after taking the drug for 2 weeks. I am going to put the drug on hold for a bit and try it again in a few weeks. Recommended? Yes."
