For Weight Loss (Obesity/Overweight) "I am a 48-year-old female weighing 205 lbs (the most I have ever weighed in my life). My doctor recommended Belviq XR (20 mg) once daily, which he felt was a good option for me since I have high blood pressure. I am also doing WW in conjunction with the med. I began the med on 5/11, today is 5/14 (4 days on it today). On Day 1 and Day 2, I experienced extreme fatigue, mental fogginess, and a low-grade headache. On Day 3, those side effects subsided until I went to bed last night and woke up from what seemed to be hallucinogenic nightmares. It was so bizarre. My dreams were very vivid and lifelike, and I woke up several times during the night. I took Advil, and it stopped, and finally I could go back to sleep. To date, I lost 3 pounds in 4 days, so it seems to be working, but not sure if I can stay on Belviq with the side effects, the interruption of sleep, and nightmares. It is quite scary to experience. I am hoping it subsides."

For Weight Loss (Obesity/Overweight) "After 1 dose of Belviq XR, within a couple of hours, I had every single side effect. Cold symptoms, dizziness, inner ear issues, lethargy, severe headache, swollen feet and hands, scratchy throat, brain fog. Had all of these flu symptoms, so I assumed that it was the actual flu and not side effects. Then I noticed the itching that others reported. I noticed swelling in my feet and hands - severe swelling. Hurt to put my shoes on. Body aches, joint pain. My mind is mush. All of these are typical side effects of the medication according to the manufacturer. What is ‘typical’ about feeling sick? I ended up having to go home from work because I was not able to function. Basically, I am out 2 days of work, $145 for medication I am not taking, $100 to see the doctor for a flu test (I don’t have the flu, I have side effects)."

For Weight Loss (Obesity/Overweight) "I started taking Belviq on December 11 and stopped on December 22. While on the medication, I experienced dry eyes, brain fog, aches, fatigue, and after the first week, I seemed to not be able to control my bladder. The medication does reduce the appetite, however, the side effects of the medication were too harsh for me. $245 dollars, the remainder of the medication will stay in the bottle."
