What Is Methotrexate?

Methotrexate is a medicine used to treat certain cancers and a range of autoimmune conditions such as rheumatoid arthritis and psoriasis.

The drug belongs to a group of medicines called antineoplastic and immunomodulating agents according to ATC code L01BA01.

That classification identifies methotrexate as an antimetabolite and a folic acid analogue, which explains both its therapeutic effects and side effects.

Patients commonly ask whether methotrexate is a chemotherapy drug or an immune treatment, and the short answer is that it acts as both depending on the dose and the condition being treated.

Brand variations exist worldwide, and the same active ingredient appears in tablets, oral liquids and injectable preparations under many trade names.

How Methotrexate Works

Methotrexate blocks an enzyme involved in folate metabolism, which inhibits DNA and RNA synthesis in rapidly dividing cells.

This action reduces the proliferation of immune cells driving autoimmune inflammation, and it slows the growth of certain cancer cells.

At low weekly doses used for conditions such as rheumatoid arthritis, methotrexate has an immunomodulatory effect rather than the high-dose cytotoxic effect seen in oncology regimens.

The differences in effect between low and high doses explain why the same medicine treats both autoimmune disease and some cancers.

Because methotrexate interferes with folate, clinicians commonly advise folic acid supplementation to reduce some side effects while preserving efficacy.

Who Takes Methotrexate?

People with rheumatoid arthritis, psoriatic arthritis and severe psoriasis are among the most frequent long-term users of methotrexate at weekly doses.

Oncology teams use higher-dose methotrexate for certain leukaemias and tumours, with specific monitoring and rescue protocols.

Pediatric liquid formulations are available for children who cannot swallow tablets, with brands such as Jylamvo and Xatmep appearing in global listings.

Patients with robust monitoring plans are typically suitable for community-based supply and home administration of some methotrexate forms.

Forms, Dosage And Practical Tips

Methotrexate is supplied as oral tablets in strengths commonly including 2.5 mg, 5 mg, 7.5 mg, 10 mg and 15 mg.

Oral liquid formulations such as Jylamvo at 2 mg/ml and Xatmep at 2.5 mg/ml are available for patients unable to use tablets.

Injectable forms come as vials or ampoules, often at concentrations of 10 mg/ml or 25 mg/ml, and prefilled syringes or autoinjectors are marketed under various brand names.

Typical weekly dosing for autoimmune disease is a single dose once a week rather than daily dosing, but exact schedules depend on the prescriber.

For oncology, dosing regimens and administration routes are disease-specific and managed in hospital settings with intensive monitoring.

When switching between brands such as Maxtrex, Metoject, Nordimet or Ebetrex, ensure the formulation and concentration match the prescribed regimen.

Always use a pharmacy label and a dosing calendar for weekly schedules to avoid accidental daily dosing, which can be dangerous.

Keep packaging and patient information leaflets to confirm strengths when using methotrexate tablets or methotrexate oral liquid at home.

Side Effects And Monitoring

Methotrexate can cause nausea, mouth ulcers, hair thinning and increased susceptibility to infections, especially during the early treatment period.

Because methotrexate affects rapidly dividing cells and folate metabolism, liver function tests and blood counts are routinely monitored to detect toxicity.

Serious adverse effects include liver injury, bone marrow suppression and lung inflammation, which must be recognised and reported promptly.

Regular blood tests are standard practice and help clinicians adjust dose, pause treatment or add folic acid to reduce side effects.

If a patient develops fever, persistent cough, unusual bruising or severe mouth sores, clinicians usually advise stopping methotrexate and seeking urgent review.

Patients should avoid live vaccines while taking methotrexate unless specifically advised by the prescribing clinician.

Interactions And Contraindications

Methotrexate interacts with a range of common medicines, and some antibiotics and non-steroidal anti-inflammatory drugs can increase its toxicity.

Folic acid supplements are often recommended to reduce adverse effects and must be given at the appropriate dose and schedule to avoid reducing effectiveness.

Certain medicines used for gout, some proton pump inhibitors and other agents may alter methotrexate clearance and require dose adjustment or monitoring.

Methotrexate is contraindicated in patients with severe liver disease, significant renal impairment or active infections unless advised otherwise by a specialist.

Before starting methotrexate, clinicians usually screen for hepatitis B and C and check baseline blood tests to reduce the risk of serious complications.

Pregnancy, Fertility And Breastfeeding

Methotrexate is strongly contraindicated in pregnancy due to a high risk of fetal malformation and pregnancy loss.

Men and women are usually advised to use effective contraception during treatment and for a defined period after stopping methotrexate as advised by a specialist.

Breastfeeding is generally not advised while taking methotrexate because the medicine can pass into breast milk and affect the infant.

Fertility counselling should be offered to patients of reproductive age before starting methotrexate when treatment is likely to be longer term.

How To Take Methotrexate Safely At Home

Always follow the exact dose and schedule prescribed by the specialist or GP, and confirm the dose strength before taking or administering the medicine.

Do not take methotrexate daily for autoimmune disease unless specifically instructed, because weekly regimens are common and daily dosing can cause serious harm.

Store tablets and oral solutions as advised on the label, typically in a cool, dry place away from children and pets.

Use a single pharmacy and keep records of batch numbers and expiry dates, particularly when switching brands such as Metoject or Maxtrex.

In our online pharmacy, methotrexate is available without a prescription, with discreet delivery to United Kingdom in 5-14 days.

Contact the pharmacist immediately if a dose is missed or if there are concerns about swallowing, vomiting after a dose, or unexpected side effects.

Practical Examples

A patient started on weekly methotrexate tablets kept a marked calendar and reported fewer flares after six weeks on the prescribed dose and folic acid supplement.

A parent ordering methotrexate oral liquid for a child with juvenile arthritis confirmed the concentration on the bottle before giving the measured dose.

An older patient switching to a prefilled syringe such as Nordimet found self-injection easier after a single training session with a nurse.

Frequently Asked Questions

How long does it take for methotrexate to work for arthritis?

Benefits are often noticed after 4–12 weeks, with maximum effect sometimes taking up to six months depending on the condition and dose.

Can methotrexate be taken with alcohol?

Alcohol increases the risk of liver injury with methotrexate, so clinicians commonly advise reducing or avoiding alcohol while on treatment.

Is methotrexate the same as chemotherapy?

Yes and no; methotrexate is a cytotoxic drug at high doses used in oncology but is used at much lower, immunomodulatory doses for many rheumatological conditions.

Do I need blood tests while taking methotrexate?

Yes; blood tests including liver function and full blood count are typically performed before starting and at regular intervals during treatment.

Can methotrexate cause infertility?

It can affect fertility temporarily, and patients planning pregnancy should discuss stopping methotrexate and timing with their prescriber well in advance.
