Before you start taking the tablets, read the manufacturer's printed information leaflet from inside the pack.
Ascorbic acid tablets are usually taken once a day. Doses of 25-75 mg are sufficient to prevent vitamin C deficiency. You can take the tablets at whatever time of day you find easiest to remember, either before or after meals. If you have been prescribed a higher dose (more than 250 mg), your doctor will recommend that you take this in divided doses. Your dose will be on the label of the pack to remind you about what the doctor said to you.
Do not take more than the dose which has been recommended or prescribed.
Some ascorbic acid tablets should be chewed before they are swallowed and others need to be dissolved in water first. Check the label on the container of your supply and follow the directions given.
If you forget to take a dose, don't worry, just take the next dose when it is due. Do not take two doses at the same time to make up for a missed dose.
