Why is this medication prescribed?

When the amount of ascorbic acid in the diet is inadequate, ascorbic acid (vitamin C) is taken as a dietary supplement. Individuals who consume a small variety of foods or who experience intestinal malabsorption issues as a result of cancer or kidney disease are particularly at risk for ascorbic acid insufficiency. Scurvy is another condition that ascorbic acid is used to treat and prevent (a disease that causes fatigue, gum swelling, joint pain, and poor wound healing from a lack of vitamin C in the body). Ascorbic acid belongs to the category of drugs known as antioxidants. The body need it to aid in wound healing, improve iron absorption from plant-based meals, and strengthen the immune system. It functions as an antioxidant to shield your cells from free radicals, which may contribute to cancer, heart disease, and other illnesses.

How should this medicine be used?

Extended-release (long-acting) tablets, capsules, lozenges, chewable gels (gummies), and liquid drops for oral administration are all forms of ascorbic acid. The normal dosage is one dose per day or as prescribed by your doctor. Although ascorbic acid is accessible over the counter, some medical conditions may require a prescription from your doctor. Ask your doctor or pharmacist to explain any instructions you do not understand and carefully follow the guidelines on the container, your product label, or your doctor’s instructions. Ascorbic acid should be taken as prescribed. Never take it in larger or less amounts or more frequently than your doctor has prescribed.

The recovery from scurvy symptoms could take up to 4 weeks.

There are supplements for ascorbic acid both on their own and in conjunction with other vitamins.

Other uses for this medicine

You should speak with your doctor or pharmacist for more details if you want to take this drug for a different purpose.

What special precautions should I follow?

Before taking ascorbic acid,

  • If you have an allergy to ascorbic acid, any other drugs, or any of the substances in ascorbic acid products, let your doctor and pharmacist know right away. Get a list of the components from your pharmacist.
  • Inform your doctor and pharmacist about any additional prescription and over-the-counter drugs, vitamins, dietary supplements, and herbal products you are now taking or intend to use. Mention any of the following: niacin administered along with simvastatin, fluphenazine, and chemotherapy drugs (Flolipid, Zocor). Your physician might need to adjust the dosage of your drugs or keep a close eye on you for side effects.
  • If you have or have ever had a medical problem, let your doctor know.
  • Inform your physician if you are nursing a baby, intend to get pregnant, or are already pregnant. Call your doctor if you become pregnant while taking ascorbic acid.
  • If you use tobacco products, let your doctor know. Cigarette smoking may reduce ascorbic acid’s effectiveness, requiring you to take a higher dose. If you use tobacco products, discuss your ascorbic acid dosage with your doctor or pharmacist.

What special dietary instructions should I follow?

If you are following a salt- or sodium-restricted diet, you should stay away from some kinds of ascorbic acid since they include sodium.

What should I do if I forget a dose?

If you miss a dosage, take it as soon as you recall. If the next dose is soon due, skip the missed one and carry on with your regular dosing plan. To make up for a missing dose, do not take a second one.

What side effects can this medication cause?

Adverse effects from ascorbic acid could exist. If any of these symptoms are severe or do not go away, consult your doctor right once:

  • Diarrhea
  • Nausea
  • Heartburn
  • Fatigue
  • Flushing
  • Headache
  • Having trouble falling or staying asleep
  • Gas

Further adverse effects of ascorbic acid could exist. If you experience any odd problems while taking this vitamin, contact your doctor right once.

You or your doctor can report a significant side effect to the Food and Drug Administration’s (FDA) MedWatch Adverse Event Reporting programme by phone or online at (1-800-332-1088).

What should I know about storage and disposal of this medication?

Keep this medication tightly closed in the original container and out of the reach of children. Keep it away from excessive heat and moisture at room temperature (not in the bathroom).

Although many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning.

Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilising a medicine take-back programme is the easiest approach to get rid of your medication. To find out about take-back programmes in your area, speak with your pharmacist or the garbage/recycling department in your city. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medications website at for additional information.

In case of emergency/overdose

Call the poison control hotline at 1-800-222-1222 in the event of an overdose. Moreover, information can be found online at Call 911 right once if the person has collapsed, experienced a seizure, is having difficulty breathing, or cannot be roused.

What other information should I know?

Keep all of your doctor’s appointments.

Inform your doctor and the laboratory staff that you are taking ascorbic acid prior to any laboratory test. If a diabetic is taking ascorbic acid supplements, they should see their doctor or pharmacist about the proper urine test procedure.

Anything you want to know about ascorbic acid, ask your pharmacist.

You should keep a written record of every drug you take, including prescription and nonprescription (over-the-counter) medications, vitamins, minerals, and other dietary supplements. Every time you see a doctor or are admitted to the hospital, you should carry this list with you. Also, it is crucial to have this knowledge on hand in case of emergency.
