Qsymia Overview

Phentermine and topiramate, sold under the trade name Qsymia, is a combination medication used for weight loss. Phentermine and topiramate is associated with modest weight loss when compared with placebo.[1] This weight loss was associated with improvements in weight-related comorbidities such as improved blood sugar, decreased blood pressure, and improved cholesterol.[1] Phentermine and topiramate was developed by Vivus, a California pharmaceutical company.[2] Phentermine is a sympathomimeti...

Qsymia not working after brain tumor removal
Post a Reply
I was on qsymia, it worked great. I lost 45lbs. I had a tumor that was noncancerous and started back taking it because I gained some weight from the steroids. However the qsymia stopped working. What else can I take or do to jump-start my weight loss?

qsymia not working
1 Reply RSS
I've been on Qsymia high dosage for over a year, exercise and watch my diet carefully. I haven't lost weight in fact I've gained 10 pounds. I'm a thyroid cancer survivor taking Synthroid daily and my thyroid blood tests are fine. This is frustrating. I too skip the dosage on weekends. I've been on qsymia for three years now. Maybe I should switch to another brand. ## Weight gain can be a side effect of Synthroid and it isn't likely to change, while you are taking it. The FDA lists its other typical side effects as possibly including nausea, dizziness, headache, and hair loss. Which medication do you skip on the weekends and why do you skip it?

Qsymia Questions

When does it stop working as well as an appetite suppressant and why does your weight loss slow down? ## Hello, Lauren! How are you? Our bodies eventually get used to any medication that we take regularly for a long period of time, which causes them to stop working as well for us. There's no precise time frame that can be given though, because it can vary from person to person. Regardless of the method used to lose weight, there is almost always a plateau that you hit, at some point. Your body also gets used to whatever you're doing to spur it, such as a medication, or exercise and weight loss can slow down, unless you change something to ramp it back up, such as changing your exercise routine, your diet, or the medication that you're taking. The FDA lists Qysmia's typic...

Qsymia anxiety

My wife was on phentermine, and then qsymia. She came off qsymia and is now full of anxiety and anger. Please help. ## Withdrawal effects can be normal, if someone abruptly stops a medication, she may also experience nausea, diarrhea and headache. Why did she stop taking it? These symptoms should go away after a few weeks, once her body gets used to no longer having the medication added. Is she on any other medications?

Drinking Alcohol
1 Reply RSS
I am currently on my first week of Qsymia. I need someone's honest opinion and I will ask my doctor too once I see her again. I am not a big drinker at all but when I go on vacation I do get a couple of drinks here and then or maybe once a day. It's my vacation and I want to enjoy it. Am I going to die if I have a drink or 2 or would you recommend stopping the medication for the week and half I am on vacation? ## Hi Steph, According to umm.edu's drug interaction tool, drinking alcohol while taking Qysmia is not recommended as it may increase or decrease blood levels of topiramate (one of the active ingredients in Qysmia) potentially resulting in more side effects and/or a less effective dose. They also goes on to note that the combination of alcohol and topiramate may cause ...

1 Reply RSS
Been on 3 weeks only lost 4lbs but feel like I am losing my mind. Racing heart, anxious, constipated, awful taste in my mouth and horrible insomnia. I want to stick it out but I am scared this will cause long term side effects or really mess me up. My endo only wants me to take it for 3 months but don't know If I should stick it out. Will these side effects go away? Any thoughts? Help? Can this med cause u to have a heart attack? ## Hello, Brenda! How are you? Actually, under the FDA warnings, you should see your doctor immediately, if you experience the pounding or racing heart beats as it may not be a safe medication for you to take. The constipation, insomnia, taste changes and dizziness can be normal side effects. Are you on any other medications?

Qsymia Worked for me
2 Replies RSS
I have done very well on the medication. I have had to increase the dosage to the full amount as had been advised by the manufacturer and the FDA and after almost a full year it seems to have stopped working, which happens with most medications like this (and pain meds too). My doctor has suggested weekly "drug" holidays (i.e. I don't take it on the weekends) to stimulate it's efficacy when I resume the next weekday. Also, on those weekdays when I simply forget to take it at the early time of day, I just don't take it at all. However, as I reach the full year period in June, I am looking at loosing the monthly $75 discount. So I wrote the manuf. Vivus and asked if they would extend the discount so that I can safely taper down to get off the medication as is the recom...
