What Folic Acid is used for
Folic Acid is an important medication that is used in eye care, specifically when patients are undergoing treatment with another medicine called methotrexate. Its primary role is to help manage and reduce the potential side effects that can arise from methotrexate therapy.
- Given with methotrexate to reduce its side effects
How it works
When you take methotrexate, it can sometimes deplete the levels of a vital nutrient called folate in your body. Folate is a type of B vitamin that is crucial for many bodily functions, including cell growth and repair. Folic Acid works by replacing this folate, thereby counteracting the effects of methotrexate and helping to minimise its side effects. It essentially helps your body maintain healthy folate levels while you are on methotrexate treatment.
How it’s used
Folic Acid is available in tablet form. The typical dose is 5 mg, which is usually taken once a week. It is very important to take Folic Acid on a day when you are NOT taking your methotrexate. For example, if you take methotrexate on a Monday, you might take Folic Acid on a Tuesday or Wednesday. In some cases, your doctor might advise you to take it daily. Always follow the specific instructions given by your eye doctor regarding the dosage and timing of your Folic Acid tablets. It can be taken with or without food, but consistency is key.
Always follow your ophthalmologist’s exact instructions.

Good to know
Available without prescription, but this is not a substitute for an eye examination. If redness, pain, discharge or blurred vision persists for more than a day or two, see an eye doctor rather than continuing drops on your own.
Precautions & side effects
Folic Acid is considered an essential companion to methotrexate therapy. This means that if you are prescribed methotrexate, your doctor will very likely also prescribe Folic Acid to you. It is crucial to take Folic Acid exactly as advised by your doctor when you are on methotrexate treatment. Although Folic Acid is available without a prescription, it is not a substitute for a proper eye examination. If you experience any new or worsening eye symptoms such as redness, pain, discharge, or blurred vision that persist for more than a day or two, you must consult an eye doctor immediately. Do not self-medicate or continue using any drops on your own without professional advice.
Understanding Your Eye Condition and Treatment
At Pristine Eye Hospitals, we understand that managing an eye condition can sometimes feel overwhelming. When your doctor prescribes medications like Folic Acid, it’s usually part of a comprehensive treatment plan designed to protect your vision and improve your eye health. Folic Acid, in particular, plays a supportive role when you are undergoing treatment with another medication called methotrexate. Methotrexate is used for various conditions, and while it’s effective, it can sometimes have side effects. Folic Acid helps to mitigate these side effects by replenishing essential nutrients in your body. It’s important to remember that every medication has a specific purpose, and understanding why you are taking it can help you adhere to your treatment plan more effectively. Always feel free to ask your doctor or the healthcare team if you have any questions about your diagnosis or the medicines you are prescribed.
General Advice for Taking Oral Medications
Taking your oral medications correctly is just as important as using eye drops or ointments properly. For Folic Acid tablets, here are some general guidelines:
- Follow Instructions Carefully: Always take your Folic Acid tablets exactly as your eye doctor has prescribed. Pay close attention to the dosage (how many milligrams), how often you need to take it (e.g., weekly or daily), and any specific timing instructions (e.g., on a non-methotrexate day).
- Consistency is Key: Try to take your medication at the same time each day or on the same day each week, as advised. This helps maintain a steady level of the medicine in your body.
- With or Without Food: Unless your doctor gives specific instructions, Folic Acid tablets can generally be taken with or without food. If you find it upsets your stomach, try taking it with a meal.
- Storage: Store your tablets in a cool, dry place, away from direct sunlight and moisture. Keep them out of reach of children. Do not store them in the bathroom medicine cabinet, as humidity can affect the medication.
- Missed Dose: If you miss a dose, take it as soon as you remember, unless it’s almost time for your next scheduled dose. In that case, skip the missed dose and continue with your regular schedule. Do not double your dose to make up for a missed one. If you are unsure, contact your doctor or pharmacist.
When to Seek Medical Help
While Folic Acid is generally well-tolerated and serves a beneficial purpose, it’s crucial to be aware of when to seek professional medical attention. Your eye health is paramount, and certain symptoms should never be ignored. Even if you are taking Folic Acid, it does not replace the need for regular eye examinations or prompt attention to new symptoms. You should contact Pristine Eye Hospitals or see an eye doctor immediately if you experience any of the following:
- Persistent Eye Redness: If your eye remains red for more than a day or two, or if the redness is severe.
- Eye Pain: Any new or worsening pain in or around your eye.
- Unusual Discharge: If you notice any green, yellow, or excessive watery discharge from your eye.
- Blurred or Decreased Vision: Any sudden or gradual change in your vision, including blurriness, loss of vision, or seeing halos around lights.
- Sensitivity to Light (Photophobia): If light becomes unusually painful or uncomfortable.
- New Floaters or Flashes of Light: Seeing new spots or cobweb-like images, or sudden flashes of light, especially in one eye.
- Swelling: Swelling of the eyelids or around the eye.
- Any other concerning symptoms: If you feel that something is not right with your eyes, it is always best to get it checked by a professional.
Remember, early detection and treatment are vital for many eye conditions. Do not hesitate to reach out to us if you have any concerns.
