Ascorbic acid tablets

About ascorbic acid

Ascorbic acid is also known as vitamin C. Our bodies need vitamin C to make a substance called collagen which is required for the health and repair of our skin, bones, teeth and cartilage. We get vitamin C from the food we eat, particularly fruit and vegetables. A lack of vitamin C in our diet over a period of time can lead to a condition called scurvy, although this is rare in the UK. Symptoms of scurvy include bleeding from the gums, bruising, and joint and muscle pains. It has also been suggested that a lack of vitamin C may cause poor wound healing and problems fighting infection, although this has not been proven. Vitamin C deficiency can be treated with supplements of vitamin C (as ascorbic acid tablets) and eating foods which are rich in vitamin C.

Ascorbic acid is an ingredient of a number of vitamin preparations and some cough and cold remedies that are available to buy from retail outlets.

To make sure that this is the right treatment for you, before you start taking ascorbic acid it is important that you speak with your doctor or pharmacist:

• If you are pregnant, trying for a baby or breastfeeding. This is because, while you are expecting or feeding a baby, you should only take medicines on the recommendation of a doctor.

• Om du någonsin har haft en allergisk reaktion mot en medicin.

• 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.

• Foods that are rich in vitamin C include citrus fruits (like oranges, grapefruit, limes and lemons), berries (such as blackcurrants, strawberries, raspberries, blueberries and cranberries), cantaloupe melon, watermelon and kiwi fruit. Vegetables rich in vitamin C include spinach, green and red peppers, tomatoes, cauliflower, cabbage, broccoli, Brussels sprouts and potatoes. Try to include some of these fruits and vegetables regularly in the foods that you eat.

Although ascorbic acid is unlikely to cause any side-effects at the recommended doses, large doses taken over a long period of time can be associated with unwanted effects (mainly stomach upset). If you experience any symptoms which you think may be due to the medicine, speak with your doctor or pharmacist for further advice.

• Förvara alla läkemedel utom räckhåll och synhåll för barn.

• Förvara på en sval, torr plats, borta från direkt värme och ljus.
