For Type 2 Diabetes "I still have high blood sugar. Now I get to wake up at 3 am and spend an hour dealing with diarrhea. I have been late to work and missed important meetings dealing with these side effects. I honestly would rather go back to untreated diabetes than to continue on with metformin."

Metformin for Type 2 Diabetes "I was taking Glucophage for a number of years, and the only side effect was diarrhea at least 1 to 2 times daily. It kept my blood sugar in the low 100s. I finally lost about 60 lbs, and I no longer have diabetes even though my grandmother and mother had type 2 on insulin, and my brother now has it."

Metformin for Type 2 Diabetes "I've been taking this medicine for a month today. I have seen a significant and favorable drop in my blood sugar. However, I've never felt sicker in my entire life. Every day since starting this, I've been nauseous, even to the point of vomiting. I find that I now have motion sickness and since I take public transport, I sometimes have to get off the bus to vomit. I always have diarrhea. I sometimes have fever symptoms, chills along with a feeling of being very cold, and terrible headaches. I've also become quite anxious, restless, and moody, which may be a side effect of these side effects. I've lost 12 lbs and I find myself eating less, which is awesome but I'm ALWAYS nauseous, which is why I have no appetite."

Metformin for Type 2 Diabetes "Glucophage XR 500mg or 1000mg tabs (I either take 2 - 500mg tabs in the morning and 2 - 500mg tabs with dinner/supper, or I take 1 - 1000mg tab in the morning and 1 - 1000mg tab with dinner/supper). I totally love this medicine. It's been one of the best medicines that I have ever taken to help keep my blood sugars under control! Unlike the generic Metformin, which really messed me up and was my worst nightmare! Nobody would listen to me: my doctors, my pharmacists, the emergency room, my therapist, my psychiatrist, and especially Medicaid and Medicare Part D! So, against medical advice, I quit taking generic Metformin. A year and a half later, they put me back on Glucophage XR! Life became wonderful again!"

For Polycystic Ovary Syndrome "I've been on metformin for 2 weeks now and am so happy with the results that it makes me want to cry. I've lost 6 pounds, I have my energy back, and I'm just happy again. I feel like I'm back to myself after not being for the past 3 years. I would recommend it to anyone who suffers from PCOS."

For Female Infertility "I’ve been taking Metformin for 2 months now as I have PCOS, and I am so happy I’m pregnant. I also used the Clear Blue ovulation box as I’m so irregular, but after my first period, I’m pregnant, so don’t give up - it really worked for me."

For Type 2 Diabetes "An excellent medicine. I had hyperinsulinemia and was consuming vast amounts of sugar daily to keep my sugar from dropping, then suddenly my sugar readings became higher and higher every morning. Diagnosed with diabetes. Was given Metformin, no more carb/sugar cravings, no more lows and highs, I have been taking it for 5 weeks and I have lost 15 lbs. I had ZERO side effects. I feel GREAT!"

For Type 2 Diabetes "Only been taking this a couple of days, so will come back & review after longer-term use. But just wanted to provide some reassurance for anyone who is putting off taking metformin because they’re in fear of the side effects. I’m one of those that’ll avoid medication, mostly in case they make me feel out of sorts mentally. However, 2 days taking these, there wasn’t anything like that going on at all. The only side effects I have are what I was warned about by my GP, i.e., slight loss of appetite, going to the loo a bit more (one bout of crazy diarrhea so far!)… some mini waves of slight nausea too but nothing that made me feel ill, though. I’ve been told this settles down in a couple of weeks or so. I feel so much better from taking them already."

For Type 2 Diabetes "I started taking the immediate-release version about 3 weeks ago. My doctor started me on it because I've been pre-diabetic for 10 years, to prevent diabetes. I take 500 MG 1x daily (at night with dinner). I have had no significant side effects other than a mildly headache about 30 minutes after I take it, but it goes away on its own. I crush it and put it in milk or juice. I'm also doing weight watchers (app) and exercising 6 days a week. It definitely curbs my appetite. My weight went from 213 lbs to 204 lbs so far; I hope it keeps going down! We'll see if my A1C and blood sugar levels are going down at my Spring physical exam. I've tried every weight loss program there is. This time I feel like it's sustainable. I feel good, have more energy, eat well and I don't have to starve or obsess about eating. The medication definitely takes the edge off and is helping me lose weight and be healthier."

For Insulin Resistance Syndrome "Metformin, they say, makes you hyper-fertile. Yeah, I agree. My hormones got a little wacky for a week or so. I've calmed down now and feel pretty good. I take the dose up slow, only one 500mg pill for seven days before adding one more 500mg for another seven and so forth until I reach four pills a day. I noticed that without using any Lantus, my blood sugar readings were lower. Not low enough to discontinue the Lantus, however. I noticed while on Lantus alone, I never felt all that chipper. When I started the metformin, my moods improved dramatically, and I became a much happier person. The diarrhea did not last long but did return when I increased the dose. Getting used to the pills now and bowels returned to normal."

For Type 2 Diabetes "This drug can kill you. One of the worst reactions to a medication that I've ever experienced. Last Saturday, I could hardly walk out of a store as the muscle contractions grew worse and the pressure in my chest increased. An ER visit followed and a week later, I am still weak. It did not get out of my system in 24, 48, or 72 hours. Watch this drug closely when you are given it for treatment, especially if you have already had physical symptoms that are similar to some of its side effects. And yes, I had diarrhea, spasms which ran up into my torso, and nausea but I tried working through it all. I could barely lift my arms last Saturday and I was in pain from my feet to the top of my head. There was no comfortable place."

For Insulin Resistance Syndrome "I started a daily dose of 1000 mg metformin about 3 weeks ago. I take 500 mg with breakfast and 500 with dinner. I have already noticed more mental clarity and energy, and a few pounds starting to come off. The first 2 weeks, I didn't have any negative symptoms (it was wonderful!!!). But now, as it is becoming more absorbed into my system, I'm having extreme nausea and dizziness. I supplement this with extremely large amounts of water and protein when I feel this way. It seems to help slightly and it eventually passes within an hour or so, but I'm hoping these side effects will pass when my body becomes truly adjusted. Aside from that, I'm very grateful for the positive effects of metformin!!"

For Polycystic Ovary Syndrome "Before I took Metformin, I had an unpredictable and agonizingly painful cycle, a bad odor, and was growing facial hair. I was also diagnosed with borderline diabetes. The change between then and now is amazing. My cycle is regular and normal, I don't smell bad constantly, and my face is clean and smooth. The Metformin also controls the diabetic aspect, so I only have to take one medication for two diseases. My biggest side effect is the diarrhea and stomach upset, which is compounded by my Irritable Bowel Syndrome. This is easy to fix by eating a meal before taking Metformin. Despite the gastrointestinal issues, this medicine has changed my life for the better."

For Type 2 Diabetes "My doctor put me on Metformin after telling him I am very sensitive to all RX. Long story short, I wound up hospitalized for pancreatitis. Be wary of these medical doctors, they don't listen or care. P.S. His next recommendation was a diabetic drug that has a propensity to cause UTI. I am managing with diet and exercise."

For Polycystic Ovary Syndrome "I have PCOS and have been taking metformin, 2 tabs of 850 mg for 2 months now. I feel like it was working at first since I did get my period 6 days after taking my first pill. My doctor had me take 1 pill for the first week and then 2 pills the second week and so on. I missed my period, and I am not pregnant? Has this happened to anyone else? Did metformin only give you a period the first month?"

For Type 2 Diabetes "I have been using Metformin for 3 months to aggressively treat my pre-diabetic condition. Together with a lower-carb (185-200 mg per day/1700 calories) I have lost 29 pounds. This is about double the weight loss rate I had on the diet alone. The only side effect I have experienced is a loose stool once or twice a week. Definitely a good trade-off! I am a 49-year-old female, moderately active who has had a hysterectomy."

For Insulin Resistance Syndrome "I was prescribed Metformin 500 mg 2x/day for insulin resistance 5 weeks ago. I am down 15 pounds in a month (but still 85 to go) and have more energy to be more active in my daily life and energy to actually exercise (before I was always in pain and fatigued). I also am on a very strict diet of absolutely no carbs and low in fat/calories, so I can't be certain the success is due to Metformin. Also, this is the first time I have been prescribed meds for Type II diabetes so I cannot comment on how Metformin would be compared to, say, Invokana. However, I am pleased with it. This is not a magic pill for weight loss; I have also had to change my eating habits and level of activity."

Metformin for Type 2 Diabetes "I have been taking Glucophage XR for 4 weeks. The first couple of weeks, it made me very sick. I was told this was normal and to try to hold out and the side effects would stop. They seemed to, and then the dose was increased, and I am sick again. It works really well to get my sugar down. Before I started, it was an average of 146 or 6.7 for A1C. Now the average is 101. Since it is working, I am going to hold on for a few more weeks. I have been told that some people get used to it much faster than I have, and some people take a few months."

At first, this medication gave me such terrible diarrhea and other stomach pains, but then my nurse practitioner told me to try it with a meal, and oh my God, it's like I don't feel sick anymore! Also, try to take it with your biggest meal! I've been on it for about 2 months and a half, and with a little diet and exercise, I've lost 15 lbs! I'm 5’3, started at 218, now 203!"

For Polycystic Ovary Syndrome "After trying to conceive for a year, miscarriage, and weird periods, I was diagnosed with PCOS. Doctor started me on 500 mg a day. I'm currently 4 days away from completing the month, and I've lost 9 pounds! Literally without trying! No excessive exercising or anything. I've not had any negative side effects. None. I have felt fuller and don't have the urge to eat all the time. I no longer crave sweets or greasy food. All my PMS symptoms are completely gone! I don't feel like sleeping through the day anymore. I feel like I have way more energy. I feel normal again for once. I am so thankful that my doctor immediately diagnosed me and gave me this medication! He's going to up my dose to 1000 mg for the next 3 months. I truly can't wait!"

Not sure how it's helping my blood sugar because I haven't been rechecked yet, but I have not had any bad side effects at all and have lost 5 lbs. That's pretty good considering I lost it over the holidays without even trying when I usually would have gained weight!"

For Polycystic Ovary Syndrome "I was diagnosed with PCOS at 18 years old. I didn't start taking metformin until I was 20 for 3 years. I took 500mg three times daily. This medication helped regulate my cycles and aided in weight loss. I lost 30 pounds in less than a year. And best of all, I was able to conceive. Now, fast forward to 31 years old, and I'm back on 500mg once daily to manage my symptoms and to prevent the diagnosis of diabetes. If you can get past the diarrhea, it's a great medication that does help."

For Type 2 Diabetes "I am on slow-release metformin (1500 mg), and since changing away from the regular type 12 years ago, I have had zero loose bowels. You must insist to have a chance to try this much better version if frequently bothered by the standard pills. Even more important, please look up this fairly obscure nutritional cap... PTEROSTILBENE. It has proven to be a near miracle to free me from diabetes symptoms. I still take metformin, and only a doctor can put you on that med. But it works pretty darn well... but if you take metformin along with PTEROSTILBENE, diabetes is largely controlled. Almost like a true cure... except you have to continue both. Pterostilbene is found in the skin of blueberries and a few other plant sources. I take 2 50mg caps daily. Morning and night."

For Insulin Resistance Syndrome "I am overweight and turned out I have quite severe insulin resistance, though glucose, insulin, and the HbA1c were within the normal range. I was snacking all day, being ravenous most of the time and was eating quite a lot, including junk food. I've been on Glucophage XR for a little over three months, with the dose slowly increased to reach 1500 mg a day. Initially, I had diarrhea, bloating, gas, and all sorts of stomach issues, but within a couple of weeks after starting it, things settled down. I feel well now, my blood work results on the third month show a great improvement. My appetite has decreased significantly, and I no longer feel hungry all the time. I stick to three meals a day (about half the amount I used to eat) without any snacking in between. I have also cut down on carbs, pasta, bread, rice, potatoes, and meat. Since starting Glucophage in the end of May, I have lost 9 kg (almost 20 pounds). Overall, I am very satisfied with the results."
