For Type 2 Diabetes "I started Ozempic 9 months ago. At the time, I was a little over 200 lbs and was taking 1000 mg of metformin daily. Metformin had worked for me for almost 20 years, so I didn't expect that it had suddenly stopped working. For 3 years, I gained weight even though I worked out, and I thought it was just my appetite out of control. One random day, I realized my metformin was the problem. I saw a new doctor who prescribed Ozempic. What a miracle! 9 months later, and I’m down 40 lbs, my A1C dropped from 8.1 to 5.6, and I have virtually no symptoms from the drug other than fullness. The symptoms in the beginning did not last long either. Nausea, headache, fatigue...all cleared up within a week or 2 each time my dose was increased. It can cause what feels like constipation, but for me, it’s just that I simply haven’t eaten enough. This drug feels too good to be true. I’m so pleased with my experience so far!"

For Type 2 Diabetes "I have been on Ozempic for 3 months now, and I find this drug works like none I have tried before. The first 6 weeks were rough: burping, headaches, fatigue, nausea, but I stuck it out. I’m so glad I did. My A1C has gone from 8 to 6.8 in three months. I have lost 20 pounds, going from 180 to 160 lbs. My daily sugars have seen a vast improvement. The major thing I have noticed after being on the drug for this long is that recovery time after eating high-carb or high-sugar foods is back to normal. Appetite is still lacking, but it’s mostly an aversion to ‘bad’ food. I can no longer sit and eat an entire burger, it’s just way too much, but a healthy salad, I can eat the whole thing! I have seen major benefits from this drug. I have way more energy and no more 3 pm crash. Tips while adjusting to the drugs: Tums, Gravol, lots of sleep, light healthy meals, and remember to drink water! Also, I found injecting Ozempic in the hip lessened the symptoms for the first while."

For Type 2 Diabetes "Update: since my last report, I have not taken another dose. I’m on day 11 of feeling sick and miserable. I have indigestion from the smallest amounts of food, steady low-grade headache, sweats, fatigue, nausea, but the worst is extreme dizziness every time I stand up. This drug may work for some, but my experience from one small dose was horrible."

For Type 2 Diabetes "This is the worst drug I have ever been prescribed. I took my first shot on Sat at 4 p.m. By 10 p.m. I had a horrible headache and acid indigestion unlike anything I have ever experienced. By Sunday morning, the fatigue was so bad I could not get out of bed. Following was total lock down of my digestive system and then uncontrollable diarrhea for 5 days. The fatigue and nausea I could not shake. I spent most of the next 5 days trying to sleep and not eating due to the nausea and overall horrible sick feeling. I am a person who works out and runs 3 miles a day and is very active. I feel like a week of my life has been sucked away from me. Today is Thursday and still feeling terrible. I can only hope it wears off soon. Think very long and hard before using this drug. Do your research and read about it, it is very concerning that this is actually approved to be injected into people."

For Cardiovascular Risk Reduction "Went to my endo, desperate from dealing with both hypothyroidism and menopause. Have regularly put on 30 kg over the past 5 years up to 114 kg, have extreme fatigue, spine issues, and severe leg pain/body aches. Was prescribed Ozempic to assist with weight loss as nothing else worked. I was very worried about side effects and it not working after reading reviews. Started my 0.25 mg dose 3 days ago, injecting in the upper thigh just before bed, but didn't get the full dose as I pulled it out a tad early. Had some mild nausea the next morning that only lasted a few minutes and developed a headache, but panadol took care of that. I didn't notice much the first day and was worried that it wasn't going to work. However, on day 2, I was only able to eat about 1/3 of my dinner and felt full. Have already lost 0.5 kg in just 3 days. No other side effects that I can tell. Though I do feel more thirsty and am a bit tired; however, that's normal for me, so can't say it's a side effect. Happy so far!"

For Cardiovascular Risk Reduction "3 weeks in... Initially prescribed for weight management. While my appetite's drastically reduced, I've experienced headaches, some brain fog, and felt a little under the weather. Nausea slightly though it reduced day by day. Fatigue's unbearable. I typically have an upbeat, positive attitude and noticed a not-so-good version of myself just recently. Contemplating discontinuing treatment as excited as I am for the weight loss aspect of it :("

For Type 2 Diabetes "My side effects were bad burping and gas, extreme abdominal pain radiating into my back, headaches, extreme fatigue, and more. Three trips to the ER, one MRI, one ultrasound, and three CT scans, and the consistent diagnosis was 'everything looks perfect.' Very disappointed that an ER, GP, endocrinologist, and GI specialist all did not seem to recognize these drug side effects. I see the endocrinologist today and will discuss, looking for better options. I have had a horrible nine months. Very disappointed in both our healthcare chemists and industry in general."

For Type 2 Diabetes "I am on my 3rd week of Ozempic. So far, the only noticeable side effects have been fatigue, slight headache after injection, and it has stirred up my GERD a bit. It seems to be working with me. I am hoping all stays as it is now. Probably lucky on the side effects. I delayed taking for 2 weeks to wrestle with the possible side effects."

For Type 2 Diabetes "Started Ozempic a month ago. I had a bit of diarrhea with the first two injections. Now it is just the headache and fatigue feeling. I haven't noticed any changes in appetite. I had been losing weight for three months prior to starting Ozempic. I was down 42 pounds, since starting, I'm up six pounds. I haven't noticed any difference in my blood sugar numbers. Not impressed so far."
