Pain killers and fasting blood test

You're best checking with the person who requested the test. I know that fasting blood tests for cholesterol (lipids), iron, blood glucose, (diabetes) & such the general info is that NSAIDs & certain other meds shouldn't be taken on the day of the test as they can be sensitive to them but do check first especially if you've bad inflammation & really can't do without it.

I think so but avoid very sugary foods otherwise they might consider you as a diabetic because your blood sugar is so high. High fat can sometimes interfere with the testing procedure as well.

I wouldn't personally take it on an empty stomach.

I'm on naproxen and I personally would never take it on an empty stomach. Hope alls well with your blood tests.

Hi. I was advised to stop taking Naproxen for 5 days before any blood tests, to make sure it was out of my system and not masking any inflammation etc. This has also applied to day surgery for eg: Carpal Tunnel. It was painful as I depend on a daily dose of the maximum Naproxen, but I wanted to be sure my blood tests were accurate.

Think you should not take Naproxen while fasting.

I also take Naproxen, but never in an empty stomach.

As naproxen should be taken with food, I would wait until after having blood taken.
