Generic Methotrexate Buyer and Patient Handbook in South Africa

What is Methotrexate?

Methotrexate is a folate-antagonist medication classified as an antimetabolite and used to support Cancer treatment and manage certain autoimmune conditions. It works by interrupting DNA synthesis in rapidly dividing cells. In South Africa it is approved by SAHPRA and available as a 2.5 mg oral tablet.

Who Should Use Methotrexate?

• Adults diagnosed with certain solid tumours or haematological malignancies where methotrexate is part of the protocol.
• Patients with severe Rheumatoid Arthritis or Psoriasis when disease-modifying therapy is indicated.
• Individuals under specialist supervision who can attend regular monitoring appointments.

How Does It Work?

Methotrexate blocks the enzyme dihydrofolate reductase, preventing the conversion of folate to its active form needed for DNA and RNA production. This halts the growth of cancer cells and dampens the overactive immune response in autoimmune disease. Safety note: high-dose regimens carry a risk of bone-marrow suppression; regular blood tests are essential.

Why Choose Methotrexate?

• Cost-effective: as a generic, it provides the same clinical benefit as branded versions at a lower price.
• Proven track record: decades of clinical experience support its efficacy and safety when monitored correctly.
• Off-label uses (e.g., certain skin conditions) should only be considered after specialist consultation.

Dosage, Administration, Lifestyle and Dietary Recommendations

Recommended Dosage

• Low-dose regimen: 2.5 mg taken once weekly. Dose adjustments are made by the treating specialist based on response and blood work.

How to Take

• Swallow the tablet whole with a full glass of water.
• Take on the same day each week, preferably on a day you can remember (e.g., Sunday).
• Do not split, chew, or crush the tablet.

Missed Dose

• If you remember the missed dose within 24 hours, take it immediately and continue with the regular schedule.
• If more than 24 hours have passed, skip the missed dose and resume the next scheduled dose; do not double-dose.

Overdose

• Seek emergency medical attention immediately.
• Bring the medication packaging to aid clinicians in identifying the amount taken.

Special Populations

• Elderly: start with the lowest effective dose; monitor kidney function closely.
• Renal impairment: dose reduction or avoidance is advised.
• Pregnancy & breastfeeding: contraindicated due to teratogenic risk; effective contraception is required for women of child-bearing potential.

Lifestyle & Diet

• Avoid high-dose vitamin C supplements within 24 hours of dosing.
• Grapefruit juice can increase methotrexate levels; limit consumption.
• Maintain adequate hydration (at least 2 L of water daily) to reduce kidney stress.

Precautions and Warnings

• Regular blood monitoring (complete blood count, liver and renal panels) is mandatory.
• Report any signs of infection, persistent mouth ulcers, or unusual bruising promptly.
• Use effective contraception; methotrexate is teratogenic.
• Alcohol can worsen liver toxicity; limit intake.

Frequently Asked Questions

How long does it take to see an effect?

Clinical improvement is usually observed after 4-6 weeks of consistent weekly dosing.

Can I drink alcohol while on methotrexate?

Alcohol can increase liver toxicity; limit intake and discuss safe limits with your healthcare provider.

Is it safe to take methotrexate with over-the-counter pain relievers?

Acetaminophen is generally safe, but NSAIDs should be used only under professional advice due to kidney risk.

What should I do if I develop a rash?

Stop the medication temporarily and contact a healthcare professional; a rash may indicate an allergic reaction.

Why is a weekly dose required instead of daily?

Weekly dosing reduces the risk of severe bone-marrow suppression while maintaining therapeutic effect.

Can methotrexate affect fertility?

It can impair sperm production temporarily; men should discuss timing with their clinician when planning conception.

Do I need to take folic acid supplements?

Supplementation with folic acid (1 mg daily, except on methotrexate day) reduces mouth sores and liver enzyme elevations.

How often should I have blood tests?

Typically every 2-4 weeks during dose titration, then every 8-12 weeks once stable.
