Invokana (canagliflozin) for Diabetes, Type 2: “I was on it for a year and a half it actually dropped my A-1 C I was doing pretty good with it. I went in to get my prescription my insurance company said this will be the last time they paid for it then I found out why. There are many people that have lost limbs because of using it there is a lawsuit against the company for it. I kind of look at it as I looked out I only ended up losing two big toes and 12 surgeries on my feet - be careful.”

Invokana (canagliflozin) for Diabetes, Type 2: “I've been on Invokana for about 6 months now. It helps with my sugars but the vaginal itching is so intense I thought I was going to have a mental breakdown! I've been off it for almost a week now and still the itching won't go away! In fact it's worse. After reading some stories here I now know that it's also probably the reason I've been itchy every where which in turn has caused me to scratch so much and I've got cuts everywhere! Plus I never had had the extreme numbness and pain in my feet till I started using it! Calling the doctor in the morning cause this is all scaring the crap out of me!!!! DON'T USE THIS DRUG!”

For Diabetes, Type 2: “I have been Type 2 diabetic for about 10 years. With metformin alone blood sugar readings were gradually going up, and had become alarmingly high on waking. I've been on Invokana 100 for a year now. My blood sugar readings came down right away and the dawn phenomenon spikes have gone. HbA1c came down from 9.4 to 6.8. Have lost about 6 lbs. I have no side effects at all. Brilliant medication. I do not pay anything for my medications because I am British and it is on the NHS. I am lucky.”

Invokana (canagliflozin) for Diabetes, Type 2: “Started this medicine Invokana and I was heading to the bathroom all the time. It worked somewhat on A1c . I had several reactions while on it . Eventually this started the effect where you had to go suddenly and you better be near a bathroom . I had too many real close to accident scenarios where I would just barely make it to the bathroom . Not worth it along with other issues I was having with it . I'm not going to wear adult diapers just to take this horrible medicine.”

Invokana (canagliflozin) for Diabetes, Type 2: “I was originally on 100 mg Invokana for 8 months. A/1C dropped from 8 to 6.8 I had to stop because of fungus infection around the glads of my penis. (un circumsized) Turns out this is very very common due to excess sugar in the urine. I'm now back on Invokana and A/1C has dropped again and my weight is back to where is was before stopping Invokana. Only change this time is more frequent cleaning around the glans and wiping away excess urine. The fungus was the only side effect I had.”

Invokana (canagliflozin) for Diabetes, Type 2: “Started on Invokana three months ago. Noticed slight headache after taking it, increased urination, lowered A1c. Slowly, over a period of time, two months, I noticed increasing fatigue, weakness. Eventually this affected daily activity, I can’t even begin to describe how exhausted I became. Stopped taking the drug and within two days strength and stamina have begun to increase.”

Invokana (canagliflozin) for Diabetes, Type 2: “I used Invokana for years, along with Metformin and Victoza. At first Invokana had me running to the bathroom a lot. I had vaginal yeast infections in the beginning and once later. What was very strange the Invokana just stopped working. I no longer had urges to go to the bathroom. I told my doctor and he told me to stop taking it.”

Invokana (canagliflozin) for Diabetes, Type 2: “I have been a type 2 diabetic for 22 years. I started on invokana 150mg bid along with 1000mg metformin bid in 2016. My a1c was stuck around 8.0 and i was dehydrated with very poor skin turger. Inspite of my concerns about dehydration my arnp increased the invokana to 300mg bid. I experienced a 14lb weight loss and a1c dropped from 8.0 to 6.9. I was pleased, however The dehydration got worse and I began to experience peripheral neuropathy in my lower legs that became increasingly painful over the next few months...when my feet turned bluish purple...I stopped taking the invokana. The pain and discoloration subsided after about 3 weeks. I was on the higher dose for approx 9 months.”

Invokana (canagliflozin) for Diabetes, Type 2: “I've been on Invokana for at least 3 years. I love how it relieves you of excess sugar, but it has caused many yeast infections and a UTI. I notice when I take it, it makes me crave sugar more. I need to look into other options.”

Invokana (canagliflozin) for Diabetes, Type 2: “Where do I start? I have been on Invokamet SR for about 2 months, Diabetes 2. I've developed vaginal discharge, nausea daily, extreme diarrhea daily, itchy skin. Today was the final straw. It irritated my stomach so bad, I didn't make it to the restroom. I have no social life while taking these pills. I don't even care about the weight loss.”

Invokana (canagliflozin) for Diabetes, Type 2: “Within 6 months of starting Invokana my husband almost died from taking this drug. He was hospitalized with a sugar level of 833 and a ketoacidosis diagnosis. 6 days later he had the first of 5 operations for genital gangrene. His urological surgeon said he had only a 30% chance to survive. After 111 days in the hospital he needed home health care for 5 more months. He now is in 3rd stage kidney failure when there was no kidney disease before the Invokana. It will take at least 10 to 15 years to pay the medical bills that insurance did not pay. Every SGLT2 inhibitor, like Invokana, could do this to you! DO NOT TAKE ANY SGLT2 INHIBITOR!!”

For Diabetes, Type 2: “I am T2 diabetic for 10 years now and obese, BMI - 38, suggested by Doctor Invokana to lose weight which worked very well. sugar fasting came down to 157 from around 250 + within one week. After 1 month lost 5-6 pounds. But, very costly, so discontinued and shifted back to insulin. I visited India, in January for a wedding, met a doctor friend he asked me to continue invokana 100 or upgrade to motivyst 300 (an Indian generic of Canagliflozin . I picked the latter, got 1-year medicine ( it costs 1 dollar there, very cheap). Now, in 4 months I have lost 42 pounds and sugars are well in control without insulin. The only thing, you have to remember is to drink more water and maintain personal hygiene. It's a wonderful drug.”

Invokana (canagliflozin) for Diabetes, Type 2: “I have type 2 diabetes. I have been on Invokana for about two years. It has been a godsend for me. Before I was having blood sugars in the low 200s and my A1C at it's highest got up to 9.8. On Invokana (along with glypizide & metformin), my A1C numbers have been in the mid to low 6 range. I have had absolutely no side effects. I have also lost 32 pounds, although I have been on a low-carb diet, which probably contributed to the weight loss also.”

Hope you all find what works best!”

Ang February 26, 2019

Invokana (canagliflozin) for Diabetes, Type 2: “So was diagnosed in 2015 with type 2. My sugar levels were constantly running 285-380. Even after fasting. Was taking metformin but not as I should. Blood glucose was still up there. Started on Victoza and it came down from 12 to 10 within a few months. Progression but not pleased. My doctor started me on Invokana about 3 days ago. Went to him today because I was a little fatigued and I drive for a living. Tested my sugar and it was 163. I've not seen a blood test result like that in years. Also lost 2 lbs. After reading all the negative reviews I was so hesitant about trying this drug. Other than dry mouth and being nauseous here and there I can say thus far I'm pleased with the medication. I'm excited to see what it does for me months from now.”

Invokana (canagliflozin) for Diabetes, Type 2: “I’ve been taking Invokana for 4 or 5 years and love it. I eat normally, lost 9 pounds (which stayed off) and kept my A1c in the mid to low 6’s. My only problem was recurring genital yeast infections. This problem was forever solved by installing a toilet seat bidet. ($650, Brundell). The Brundell has worked faithfully for around 3 years, and frankly I hate to leave home! Just kidding.”

Holly W. January 10, 2019

Invokana (canagliflozin) for Diabetes, Type 2: “"I have been on 100mg Invokana for a few years now. When I started taking it I experienced a small weight loss and it appeared to lowered my A1C. One month in I stopped having periods, experienced occasional yeast infections and vaginal itching. Over the years the side effects have grown more intense and frequent. It's miserable! Within the last two weeks I have started having discomfort and a burning feeling in my right foot. I contacted my doctor's office to inquire how to ween myself off this medication, but I was told I needed to make an appointment to 'discuss my options'. I've had enough of the side effects! I am taking myself off this medication whether my PCP agrees or not. Considering my experience with side effects, reading other reviews from users, I will not be taking it again."”

Invokana (canagliflozin) for Diabetes, Type 2: “I took Invokana. At first it was ok & sugar levels dropped and I lost 5 lbs, but at first I had a coupon and samples. I could not afford the $400 a month and medicare does not cover it. I continued to get samples for several months but then the vaginal itching began. From day 1 I had a terrible itchy rash on my arm. My Dr. sent me to Dermatologist, Neuro Surgeon, Neurologist and finally physical therapy thinking it was related to the bank of nerves from back to shoulder etc. (I also have a collapsed vertebrae in that area). Finally I stopped the Invokana & itching stopped, weight came back, sugar levels soared but lo an behold, the rash on my entire left arm & shoulder disappeared and never came back!”
