Hiya
I'm not a health care professional but maybe speak to them again. I was reading yesterday on xenical.com that there was no known benefit for prescribing xen for 4 years - it didn't mention anything like 1 year (which is what I was advised when I took Reductil, a completely different type of drug). I did a bit more research and found the following: -
WILL I HAVE TO TAKE XENICAL FOR THE REST OF MY LIFE?
One of the benefits of Xenical is that while you lose weight, you are changing your eating habits and lifestyle. By the time you have reached your goal, you may be able to maintain your weight through diet and exercise alone. If, however, you start to regain weight, you can safely resume taking Xenical. Xenical has been shown to be safe for up to two years of continuous use. Xenical can become part of your long-term weight maintenance program.
Can you maybe have a discussion about it with your Dr?
