I am seventy years old and in pretty good health, I am borderline type two diabetic. My doctor prescribed Metphormin and within a week I was passing multiple small kidney stones and after about a week , still passing stones, then I quit for a couple of weeks and the stones subsided, then I started taking the drug again and the stones started back up again, now I have had a history of stones in the past but nothing as frequent as this. I started taking 2000 mg. of Calcium each day and haven't been bothered with stones in several years until I started taking Metphormin. This is the only Generic drug that I know of for non insulin dependent diabetes. I may try it again for another test. I have decided that my health is my reasonability with loosing weight, diet and exercise.

I have been on Metformin 250mg twice daily for about 7 months. My first ever kidney stone event occured at 5 months with a second event at 7 months. Metformin was the replacement for Avandia which I had taken for years without incident. I am 68 years old.

I was diagnosed Type 2 diabetic late 2010 and started onn Medformin 250 mg twice a day. very strange that my blood sugars were normal afdter 1 week on the meds and continued to be normal even after having a none fasting blood sugar and A1C done, which were all normal as well.
Recently I had kidney stones from hell and was rushed to the hospital after being on Medformin for 6 Months.
Being in the pharmaceutcal field I am convinced that Medformin causes Kidney Stones. Drug companies do not report all side affects from clinical trials to the FDA, this I can tell you they use the data that is good for them to get their dug approved. I am sure that the numbers are higher for people developing kidney stones from Medformin.

- Dysphagia with flomax to move kidney stones
I was experiencing extreme pain in right upper abdomen and was checked at the hospital and kidney stones were diagnosed. Flomax was prescribed in september 2014. I only took about 2 days worth after pain stopped. But then pain returned in December so i decided to continue taking flomax but i suddenly got stroke like complications so i went back to the hospital where they removed the kidney stones. But my dysphagia is still holding on today February 2 2015. I have seen an ent that said it looks fine and must be mechanical. I have a gastrologist appointment and a neurolist appointment coming up. Hopefully someone will give me an answer how to fix this. In the meantime i can not eat solids(no applesause ) i just chug water and cough it back up if it goes the wrong way. And the same with liquid fruit shakes which are all that i can tolerate. Thank God i have not developed pneumonia or other issues but the constant coughing is putting a toll on me. For anyone who wants tips on dealing with this just keep looking for anything that can help relieve your swallow function.
- Blood sugar level while taking veltrex
I been taking Veltrex for a viral infection in my eye for 3 days and today my blood sugar was 448.My normal blood sugar runs around 146.
- Hair loss with metformin hydrochloride usage
I have been taking the drug Metformin Hydrochloride for about 5 months and definitely find that I am losing hair which is a problem I have never experienced. Always had the healthiest hair, no problems. Well, I am finding that I am losing lair significantly and feel that the manufacturer of this drug should post that this is a side effect as so many have been complaining of the same side effect. I also began having problems with my teeth and always prided myself of having great teeth with no problems. I also understand that if there is a deficiency of Vitamin B12 that this together with taking this drug can cause these issues of hair loss and mouth/teeth problems. Again; I feel this should be totally and more readily informed to anyone taking this drug. I don't feel that anyone should have to give up things important to them to maintain a healthy way of living...I am going to see my physician and discuss what other options that may exist as I am not feeling very comfortable with this drug and the side effects I am experiencing.
- Ranexa and erectile dysfunction
I have experienced moderate ED with taking multiple heart and NO meds. This has been manageable and acceptable. Cardiologist added Ranexa (Ranalozine) 3 weeks ago and I am now experiencing complete erectile and ejaculatory failure.
- Victoza and liver cancer (cholangiocarcinoma)
My husband was recently diagnosed with stage 4 liver cancer after taking Victoza for several years. The doctor discontinued the Victoza when the cancer was diagnosed but he actually started feeling better after he stopped it until the cancer started progressing. Since cholangiocarcinoma nd pancreatic cancer are similar, is there a link between Victoza and cholangiocarcinoma?
