For Type 2 Diabetes "I took one dose of Ozempic and I have been sick ever since. Diarrhea, vomiting, nausea, stomach cramps, and a little dizziness. This is terrible, will never use again. Can someone tell me how long these symptoms last?"

For Type 2 Diabetes "Two days after the injection, I get a pretty bad headache, indigestion, and a bloated feeling that lasts the day. This week (6th shot) has been different. It’s the second week the dose was raised from .25 mg to .5 mg. I felt like I had to throw up. The indigestion, burping, constipation, sore muscles, aches, and heavy sweating all felt like I had a horrible flu. I stayed home from work. I went back to work today, when I normally get the headache, and had heavy sweating, burping, indigestion, cold clammy skin, bloating, diarrhea, and depression and anxiety (years since I had either one). Tonight I still have bloating, wrists and shoulders sore, and indigestion with burps. My neck is really stiff. The normal headache has started with a little dizziness. I am still debating what to do as this has been an effective medicine. My blood sugar has gone from 290 to 90 to 140 when I check it. I have lost weight as well."

For Weight Loss (Obesity/Overweight) "I am a 45-year-old woman. Started Ozempic .25 mg dose 6 weeks ago, increasing to the .5 mg dose after 4 weeks. Lost 13 pounds so far, which makes me happy. Started with some nausea, some explosive diarrhea, and a general fullness feeling, and no cravings. Now I’m experiencing more constipation, and after the last injection, a dizziness/lightheaded feeling. Don’t like that at all. It never goes away. Don’t know if it’s related, but also tingling and some numbness in one foot. I’ll try injecting my thigh next time and see if that helps the dizziness because I definitely do not enjoy that feeling. Almost a jittery feeling as well. Weird. So I’m hoping these will improve over time as I am liking the weight loss results so far. I’m wondering if anyone else has had this dizzy/jittery feeling and if it will go away."

For Type 2 Diabetes "I started taking Ozempic 2 and a half months ago, starting at .25 dose and worked up to 1 mg dose. I had diarrhea on and off for the first 2 weeks. My blood sugar went up to over 200 every day and to 300 a few times. I have never had blood sugars reach 300 before, and fasting readings in the 200s were non-existent. I had significant dehydration after the 2nd week with vomiting and dizziness. My doctor prescribed insulin to bring down my sugar and said I wouldn't see glucose control until I was on the full dose of Ozempic. I've been on the full dose for a few weeks, and my blood sugar is still out of control, even with insulin and Metformin. Ozempic doesn't work for me, and the past few months have been a huge setback in my diabetes management. My A1C prior to starting Ozempic was 7.3. I have been working with a dietitian for years and follow a low carb diet. I exercise every day. I hope when I get off Ozempic my blood sugar stabilizes, and I haven't damaged my system."

For Type 2 Diabetes "My doctor prescribed Ozempic for me at the beginning of January, starting at the .25 mg dose and working up to the 1 mg dose, which I have been on for a few weeks now. I have seen noticeable improvements in my glucose levels, which are now at a normal range, which they had not been for years. It was also prescribed to help with weight loss. I have not found it to be particularly helpful in this regard. I am losing small amounts of weight, but a lot of this has to do with a modified diet that is conducive to weight loss. The side effects I have experienced and continue to experience are stomach cramps and diarrhea, sulfur burps, some constipation, lightheadedness, and dizziness, which is the worst one for me. I was at the hairdresser today, and on leaving I almost passed out and had to go back inside to sit down, and there was a big fuss, etc., etc. It was very embarrassing and scary. I so desperately want to lose weight and think that it will eventually work for me, so I am going to keep taking it."

For Type 2 Diabetes "I started this drug to try and lower my A1C, which had climbed to 7.2. My nurse practitioner put me on it. She showed me how to do the injections, but no warnings of side effects. I took a .25 dose for 4 weeks, suffering pain in my stomach that radiated to my back. Absolutely no craving to eat anything at all. Had constipation. Then I went to a .5 injection and was fine for a bit until severe nausea began, along with dizziness and vomiting. I thought it was going to be the end of me, because then the unrelenting diarrhea began. I waited days in bed, so very ill, and decided to quit this awful medication. I have lost 6 pounds, and my morning glucose numbers are 107, it's lower, but feeling this deathly ill just isn't worth it. I quit the medication, though I understand it could take 5 weeks to leave my body. Beware of this drug."

For Type 2 Diabetes "I started taking Ozempic at 0.025 mg for two months, primarily relying on meal replacements for diabetes twice a day along with a small amount of cereal (Grape Nuts). During those two months, I lost 30 pounds. However, I experienced dizzy spells because I was also taking high blood pressure medication. Once I stopped the blood pressure medication, the dizziness went away. I then increased my Ozempic dosage to 0.050 mg, and that's when things took a turn for the worse. I started having sulfur burps (long and frequent belching), excessive gas, diarrhea, and if I overate cereal, I would vomit. Even if I didn't eat anything, I would still experience vomiting. I lowered the insulin dosage, and it improved. After a month, I was able to handle the 0.050 mg dosage. Later, I increased it to 1 mg. At this point, I wasn't losing weight anymore, but I experienced hunger pains and started eating other things. On and off, I would have episodes of diarrhea, belching, and gas. Additionally, I started experiencing pain under both sides of my ribs, bloating, belching, diarrhea, and gas. I had blood work done, which revealed that my thyroid levels were significantly off. I am scheduled for an ultrasound to examine my thyroid, pancreas, liver, gallbladder, and GI tract, among others."

For Type 2 Diabetes "I started on 0.25 for four weeks, had nausea, dizziness, burping nonstop every day, off-the-wall gas, and bloating. Went on 0.5, more or less the same side effects except more abdominal pain. Then went to 1 mg, my skin started feeling like I had a bad sunburn from the waist up. It hurt when clothes touched it. Four weeks later, went on 2 mg. All same symptoms. Then I started having severe neck pain and shoulder pain. Was on 8 months and only lost 16 pounds. A1c went from 7.5 to 5.5, but a lot had to do with eating less. I have EPI, so it was not worth it to me to take it anymore. Also, thyroid cancer runs in my family. Had a friend tell me her friend got thyroid cancer after 3 months, also had a lot of diarrhea. Now I'm off, no symptoms, skin feels better, and sugar around 130."

For Type 2 Diabetes "I am only on week 2, so I am going to give it a shot, even though I am experiencing some side effects. I am a DMII with an A1C of 11.0. I have experienced a lot of dizziness, (I have BP issues as well), feeling bloated, diarrhea, and blurry vision. I can only hope these effects go away with time, as I really want to be on this medication for DM and weight loss."
