Do allopurinol side effects worry you?
Allopurinol is a powerful drug, so perhaps it is not surprising that many people worry.
Stop worrying and learn how this medication really helps gout, as long as you use it correctly.
I list the standard allopurinol side effects below, but before you look at these, you need to know about one side effect that is rarely explained properly.
This is not a side effect of allopurinol as such, as it applies to all uric acid lowering therapies. When you lower uric acid properly, to a level that gets rid of old uric acid crystals, the melting uric acid crystals can trigger a gout flare. So this is sometimes painful. But it is an expected consequence of proper treatment. Which is easily controlled by six months with a gout pain care package.
Don’t avoid allopurinol just because it might trigger a painful flare. This is one side effect that you should welcome, as it indicates that you are getting better. This effect will diminish, as long as you continue taking allopurinol daily and get your uric acid level checked frequently.
As I’ve said many times in the gout forums:
If you take allopurinol you might get a gout flare. If you do nothing, you will get a gout flare.

Allopurinol Anxieties Feedback
I created this website to help me overcome allopurinol anxieties. Now, allopurinol is my best friend. So I don’t need this information. But I’d like to make it more relevant to you.
I can only help you if I know more about your particular concerns about allopurinol. Then I can change my message so it helps you solve your personal allopurinol issues. So before you tell me, here is some feedback that I’m currently reviewing to try and make this page better:
23 Nov 2019: Are Allopurinol and Uloric the same?
My response to that is that they are not the same. But they both help gout patients by treating excess uric acid. So they need similar gout patient treatment plans to manage each stage of gout recovery. Therefore you must discuss those stages with your doctor. Especially to arrange blood tests and prescription dose reviews.
However, in the context of this page, I believe the concern here is if Uloric has the same side effects as Allopurinol. In which case, they are very different. Because they act on different parts of your body so the effects are different for each drug. Therefore you must discuss your concerns with your doctor. Specifically to arrange appropriate screening tests. Then to discuss the points I covered in the previous paragraph.
Please note that I will review all feedback with GoutPal Learners before I update this page. So if you are interested in extra information about allopurinol anxieties you should subscribe to my Pre-Launch Newsletter. Because that is where I announce new information first.
