I am a 32 yo, 5'6" female, weighing 255 lbs (sometimes 253 depending on the day!). I was on Phentermine for 4 months, beginning in February 2015. I have lost almost 20 lbs since then (starting weight was 273- my heaviest ever). Since Phen alone is only approved for short-term use, my doctor has switched me to Qsymia. I went immediately from taking 37.5 mg of Phentermine to the 2 week starter dose (3.75 mg) of Qsymia (Phemtermine/Topimax). I lost MAYBE 2 lbs. I'm wondering if my previous tolerance/plateau with Phentermine (since I literally was on Phen one day and started the low dose of Qsymia the next) may be the reason I'm not really seeing a drastic weight loss immediately (like I did with Phentermine and like I see other people claiming with Qsymia). I am eating as I was on the Phentermine, but I'm hoping that today, when I start the 7.5 mg of Qsymia I begin to see more results. I've heard amazing things about Qsymia and I was pleased with Phentermine, but Qsymia is long-term, too. Has anyone else encountered a slow start to Qsymia, but then a steady weight loss? I'm afraid my tolerance to Phentermine may hinder my Qsymia preogress- and it's EXPENSIVE!! Thanks for any input!! :)
Went from taking Phentermine to Qsymia- hardly any weight loss on Qsymia starter dose?

I just started the low dose and I also notice that this is not helping I just got off of phentermine too... The larger dose one will help is that what you are saying. I'm so disappointed
Hey you sound just like me been on 37.5 phentermine off and on for years love it but after a few months it stops working but I also went straight from 37 ..5 or.7 whatever it is to 3.75 does not seem to be working except severe dry mouth hope the next dosage works since qsymia is long term
I think you'll see more weight loss after the increase in Qsymia. Here's a link of what 100s of people say about their experiences with Qsymia:
