Does methotrexate affect your eyes?

If you’re taking methotrexate, you may be wondering if it affects your vision. Many people are prescribed this medication for various illnesses such as cancer and autoimmune diseases like rheumatoid arthritis. Hence, there’s a genuine concern about how the drug affects our overall health. While many side effects come with taking methotrexate, the question remains: does methotrexate really affect your eyes?

The short answer is yes!

Methotrexate can indeed cause ocular complications in some people who take it regularly! This article will explain what those possible eye problems might be, why they happen, and what to expect if you experience them.

What is Methotrexate

First things first; let’s understand what methotrexate is! It’s one of the most commonly used drugs when dealing with conditions such as psoriasis or rheumatoid arthritis. It works by reducing inflammation caused by these debilitating ailments.

How does Methotrexate work?

It reduces inflammation levels by inhibiting certain metabolic pathways associated with cell division. Ultimately limiting its growth while impairing enzyme systems necessary for cells’ replication – antigen-specific lymphocytes being no exceptions.

Since cells are continuously dividing/replicating themselves within the immune system during inflammatory responses (that cause pain/swelling), Methrotexae impedes their growth via deactivating ‘Folic Acid.’

A reduction of folates causes DNA synthesis to become impaired thereby causing cellular death / destruction among active immune cells hemming down inflammation from reaching high degrees readily seen in affected individuals experiencing painful swelling or joint stiffness often resulting incapacitation(lessened motility).

Does Methotrexe Affect Eyesight ?

There have been reports that suggest long-term use or high dosage intake could lead to ocular complications between 2% – 13% amongst patients without preventative measures in place as highlighted below:

Dry eyes

It’s not uncommon for methotrexate users to experience dry-eye syndrome. This happens when the eyes are unable to lubricate themselves correctly and can cause discomfort, itchiness, redness or a feeling of grittiness/pain.


Cataracts with long-term usage do occur with methotrexate but at low frequency. It occurs when a clouding develops on ‘lens’ which could lead visually impairments similar to that caused by aging processes like presbyopia making it difficult seeing things up close due decreased focusing power resulting from loss elasticity in lenses preventing them adjusting so they focus light onto your retina.

Retinal vasculitis/damage (Warning! You might feel like you’re reading sci-fi)

Retinal Vasculitis refers inflammation occurring within small blood vessels supplying oxygen-rich blood around retinas/eyes regions causing damage which may result subtle/blurred vision, scintillations (flashing lights), full-blown visual field loss if allowed unchecked entirely leading irretrievable blindness amongst affected individuals despite prescribed therapies being adhered strictly according specialists treating patient(s).

What Could Possibly Lead To Complications?

Several internal factors contribute towards predisposition developing ocular complications while consuming Methrotexae including high dosages,- prolonged use-age – pre-existing ophthalmic health issues such as glaucoma / diabetes type 2 related chronic situation among specific demographics highly prone exhibiting ocular anomalies documented sometimes leads inter-state consultation amongst physicians optimizing patients’ treated individually rather than prescription-based medical approach taking into account confounding symptoms peculiar per-body constitution seeking underlying sources treat appropriately warrant remission pathologies safely within control confines minimizing morbidity cases mishandled diagnoses prior intervention setting off long standing debilitating circumstances looming upon significant proportionals unintentionally failed diagnosis not possible without putting new measures counteract this possibility evaluating efficacy detoxifying organs renal/liver activities slowing potentially lethal interaction towards incidental intake affecting overall wellbeing.

How To Tackle Ocular Complications Associated With Methotrexate

Some measures could minimize the chances of developing ocular complications while taking methotrexate, such as:

Regular Eye Checkups

It is highly recommended to visit an optometrist once every three months to monitor your vision and any other related issues that might arise. For instance, glaucoma or diabetic retinopathy management concerning dosage scheduled be optimized closely tracking systemic responses ensuring adverse effects minimized optimally within limits tolerable patient(s).

Eyedrops / Artificial Tears

If experiencing dry eye syndrome (DES), eyedrops/artificial tears help alleviate symptoms providing lubrication necessary achieving healthy eye-corneal surface minimizing irritations caused dryness causing a clear breakdown cornea visibly seen reducing clarity can impede activities requiring high level desired ably.

Frequently asked Questions (FAQs)

These are some common questions that patients taking methotrexate often ask about its possible impact on their eyesight:

  • Q: Can I stop using methotrexate if I experience these side-effects?

A: No, you shouldn’t just abruptly stop using it without consulting with your doctor first as this could have even WORSE implications on your health in general!

  • Q: Is there anything else we should watch out for when consuming Methrotexae regularly?

A: Indeed! We’ve compiled a list below highlighting said items critical noting before & whilst under treatment plans too given varying underlying predisposing factors individual cases entail managing pre-existing conditions prior starting therapy maximized desired outcomes quickly without unwanted deficits/limitations were implementable after meticulous differential diagnosis’ already conducted

Final Thoughts

As highlighted above, sometimes drugs affect our bodies in ways we may not expect. If you’re on methotrexate and are worried about potential harm to your eyesight, do not hesitate to contact your doctor or optometrist as soon as possible to discuss ways you might avoid complications early on, ensuring prompt intervention occurs whenever necessary minimizing risk(s) stemming lasting-lasting morbidity.
