Drug introduction

Folic acid is a B vitamin that is essential for good health. In Hong Kong, folic acid is commonly used to prevent anemia and neurological problems. Pregnant women especially need folic acid to promote healthy fetal development and prevent neural tube defects. In addition, folic acid has benefits for cardiovascular health and memory function. In Hong Kong, folic acid is usually supplemented through oral supplements, but should be used with medical advice to ensure appropriate dosage and usage. Do not overuse folic acid on your own as overdose may cause adverse effects. If you have any questions or adverse reactions, you should consult your doctor immediately. Overall, folic acid is an important vitamin that is vital for health, especially for pregnant women and people who need extra supplements.

Dosage

How to use: Folic acid is usually taken by mouth and is recommended to be taken in the morning or evening. Generally speaking, folic acid can be taken with food or on an empty stomach, but it is best to avoid taking it with calcium products to ensure the absorption effect of folic acid. While taking folic acid, you should avoid eating too many iron-containing foods as this may affect the absorption of folic acid.

Dosing Guidelines: For adults, a typical starting dose is 400 mcg to 800 mcg of folic acid daily. For pregnant women, it is recommended to take 400 to 800 micrograms of folic acid daily to prevent neural tube defects. For children, dosage depends on age and specific circumstances, with 50 to 400 mcg daily recommended. The doctor may adjust the dose according to the patient's needs. Please do not increase or decrease the dose on your own. You should take it as directed by your doctor. For patients taking folic acid long-term, doctors may check blood levels of folic acid periodically to make sure the dosage is appropriate.
