Allopurinol - Dosage and How to Use

How should Allopurinol be used?

Your doctor would normally start it at a low dose and gradually increase the dose if necessary (typically based on the uric acid concentration in the blood). This helps to make you tolerate the medication better and lessens the likelihood of the gout flares initially.

Be patient and take it at the dose recommended by your doctor. The benefits are slow to come so do not discontinue the medication unless skin rashes as detailed above occur.

Take it after meals at the same time every day. Do drink plenty of non-caffeinated/non-carbonated fluids throughout the whole day, especially during the early part of the day, unless your doctor tells you to restrict fluid intake. This is especially important if you have a history of kidney stones as adequate fluid intake may help to dissolve existing or prevent new stone formation.

What should I do if I miss a dose?

If you forget to take you medication at the usual time, you can take it as soon as you remember about it. But if it is near the time for the next dose when this happens, just skip the missed dose and take the next dose as usual. Do not take more than the usual scheduled dose to make up for the missed dose.

What should I do if I overdose?
