For Type 2 Diabetes "Started it and within the first week it caused severe dehydration and diarrhea (at least 6-10 times daily). Couldn't keep solid food and made me feel dizzy, disoriented. Had to go to the emergency room because of this. I don't think doctors or the drug companies are giving their patients enough warning about how dangerous this could be."

For Type 2 Diabetes "I have been taking this for 3 days. Not long, but I have had screaming headaches and my hand joints hurt. Last night, it felt like my heart was flipping inside my chest. Maybe 3 days is not long enough, but after reading other reviews, I think I will stop. I also cannot get enough fluids and woke up this morning dehydrated to the extent that my mouth was dry and hurt."

For Type 2 Diabetes "My average glucose HbA1c was 9.5. Doctor prescribed Farxiga 10 mg. It reduced sugar to 7.1 HbA1c. But the side effects were just dangerous. My urination increased a lot and thus my dehydration. So huge constipation, dry eyes, penile infection. Thus, I have stopped this medication and moved to a different one."

For Type 2 Diabetes "I would advise everyone to quit Farxiga and Ivokanna. I have been on it for a year, and it wasn't bad at first, but I've had numerous kidney infections, and lately, it has been making me so sick (cold sweats, dehydration, weird feeling when peeing). And USA Today just dropped an article this week about these two drugs causing flesh-eating bacteria in the genitals. I'm not kidding at all. Just do an internet search for Farxiga and flesh-eating bacteria. There you will see plenty of brand new information about how dangerous this is. My Farxiga script is in the trash, and I'm scared to death of the damage I have been doing for the last year."

For Type 2 Diabetes "After 1 1/2 weeks of taking Farxiga, I went into severe dehydration that included dizziness, being lightheaded, not being able to stand for more than a minute without feeling like I was going to faint, extreme shortness of breath, chest pain, pain in my lower back and sides, excessive thirst, and dry mouth. Luckily, my daughter has had medical training and recognized that I had severe dehydration. I had to begin immediate fluid replenishing as well as salt replacement. Farxiga is the only thing that had been changed about my regular schedule, and upon looking at the maker's website, we found that dehydration, kidney problems, increased bad cholesterol levels, and UTIs are just some of the regular side effects that go along with taking this."

For Type 2 Diabetes "Started Farxiga, was already on Metformin XR. At first, I lost weight, blood sugars stayed the same, now increasing. Sugar levels stay high for some time. I have an increased thirst and frequent urination. Been on it for about a year. Now I have gained weight, suffered dehydration a couple of times, had to have an IV of fluids. A1C is climbing, started out at 8.1, now 8.9. I woke up this morning with upper left quadrant pain. For the past two weeks, have had smelly urine, almost acidic. Swelling of eyes and crusty eyelids. Hives on neck. Got tested for lupus, was negative. Going to see the doctor as soon as I can get an appointment. Going to stop taking this med, now! I stopped, and all side effects stopped. Thought I would give it a try one more time."

For Type 2 Diabetes "I was started on Farxiga as my first Type II drug about 6 weeks ago. I started with a fasting reading of 360, and in those 6 weeks have regular readings below 180 after eating. I have had slight side effects - some headaches and dehydration (I think the headaches are actually linked to being dehydrated), and a lot of urinating, but so far nothing major. Bonus - I've even lost about 8 pounds in that time with very little change to my eating habits (I still eat sweets, but have cut back a little, but not nearly as much as I should) and adding very moderate exercise, like walking an extra 30 minutes a couple of times a week. I'm basically trying to keep to 60-75 g of carbs for each meal, and this has worked well for me. My doctor was worried about cost, but I got a 3-month supply for about $33 (CVS prescription plan through my work). So far I'm very happy with Farxiga, but this being my first diabetes drug, I have nothing to compare it to at this time."

For Type 2 Diabetes "Started out fine. As it built up in my system over many months, I was getting a very dry mouth and then dry eyes. I thought my problems were over when I stopped taking the drug, but gut pain got really bad. I had stopped taking Farxiga 3 weeks before the abdominal pain got so bad and also included a really bad headache. Sure didn't help with thinking, I double paid the electric bill. Evidently, I'd become dehydrated. The low-salt diet hadn't helped the situation."

For Type 2 Diabetes "Have stopped taking it as I was having to pee all the time (every 1-2 hours). Feeling dehydrated. Yeast infection. Hair falling out. Only been taking for a month. Don't know what it's done for my A1C, but my levels are higher than normal."

For Type 2 Diabetes "I have been on Farxiga for a little less than a month and am experiencing headaches, extreme scalp itching, shortness of breath, back pain, and dehydration. I generally drink tons of water, and prior to Farxiga, did not have to urinate as much as I do. I also think that I am getting a yeast infection. I was on Janumet and Jardiance prior to this, but my insurance company stopped covering both, so now I am forced to take this or Invokana... I don't like this medication and would prefer to be on what I was taking before. If you have any say-so in the matter, DO NOT TAKE FARXIGA!!"

For Type 2 Diabetes "I have type II diabetes and heart stent placement - originally took Metformin, but didn’t like the side effects - my endocrinologist actually recommended going on Farxiga instead - initially felt better for 3 months on prescription and lost about 15 lbs - but told my cardiologist I was losing muscle mass (especially in arms and legs), was severely dehydrated all the time (actually got wrinkles on my calves) and was experiencing hair loss, and my eyes were getting blurry (had eye exam - was ok but lids crusted all the time) with discharge drying in the corners of my eyes - was going to renew my 3-month prescription until Walmart says the copay is $760 and that’s with insurance - WellCare says it’s a tier 4 drug and the price rose to over $1,650 for 3 months - if I want a refill for just one month, it’s $454 - what to do? WellCare says a comparable drug in tier one is Glipizide, but I’m not sure what to do."

For Type 2 Diabetes "Was on it for about 4 days. Got dehydrated, malaise, and extreme nausea. I stopped taking Farxiga and went back to the previous drug I was taking. Feel much better now."
