How should I use vitamin A?
Use exactly as directed on the label, or as prescribed by your doctor.
Vitamin A oral is taken by mouth.
Vitamin A injection is injected into a muscle. A healthcare provider will give you this injection if you are unable to take the medicine by mouth, and can teach you how to properly use the medication by yourself.
Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you don't understand all instructions. Prepare an injection only when you are ready to give it.
The recommended dietary allowance of vitamin A increases with age. Follow your healthcare provider's instructions. You may also consult the Office of Dietary Supplements of the National Institutes of Health, or the U.S. Department of Agriculture (USDA) Nutrient Database (formerly "Recommended Daily Allowances") listings for more information.
A child's dose of vitamin A is based on the age of the child. Ask a doctor or pharmacist if you have questions about giving vitamin A to a child.
Swallow a vitamin A capsule whole and do not crush, chew, break, or open it.
Eating fatty foods can help your body absorb vitamin A.
Never use more than the recommended dose of vitamin A. Avoid taking more than one vitamin product at the same time unless your doctor tells you to. Taking similar vitamin products together can result in a vitamin overdose or serious side effects.
The total daily amount of vitamin A you receive includes vitamin A in the foods you eat combined with taking vitamin A as a supplement.
Store at room temperature away from moisture, heat, and light.
