2. What is Methotrexate? (Methotrexate kya hai)

Methotrexate is a prescription medicine used in Pakistan for Rheumatoid Arthritis (RA), Psoriasis, and Psoriatic Arthritis. It is a folate antagonist — it inhibits the DHFR (dihydrofolate reductase) enzyme, which stops rapidly dividing cells and reduces inflammation. Very important: for RA and psoriasis this medicine is given WEEKLY — daily dosing is a serious and potentially fatal medication error. Do not take without a doctor.

10. Warnings (Ihtiyat)

• Methotrexate for RA/psoriasis is taken WEEKLY — NOT DAILY. This is a classic medication error. Daily dosing can cause serious toxicity and death. Confirm "weekly" is written on your prescription.

• Methotrexate is a Category X teratogen and abortifacient for the foetus. It is absolutely contraindicated in pregnancy. Women: do not conceive for 3 months after stopping Methotrexate. Men: 6 months after stopping.

• Folic acid 5mg weekly (on a SEPARATE day from Methotrexate) must be co-prescribed. This reduces toxicity.

• Regular monitoring of CBC (Complete Blood Count), LFTs (Liver Function Tests), and creatinine is essential — follow your doctor's schedule.

• Liver damage can occur with cumulative dose. Avoid alcohol — this further increases the risk.

• Live vaccines (e.g. MMR, Varicella, BCG) must not be given during Methotrexate treatment.

11. Precautions (Ahm ehtiyaat)

• Use effective contraception during Methotrexate and after stopping (women: 3 months, men: 6 months)

• Avoid alcohol completely — the risk of liver toxicity increases greatly

• Methotrexate can increase photosensitivity — use sunscreen

• The risk of infections increases due to reduced immunity — see a doctor immediately if fever or signs of infection appear

• Below 25°C, in a cool and dry place
• Keep well out of the reach of children — it is toxic

12. Side Effects (Nuksanat)

• Nausea (mahtli) — can be reduced with folic acid and by taking after food
• Mouth ulcers / stomatitis
• Fatigue (thakawat)
• Elevated liver enzymes

• Severe hepatotoxicity / cirrhosis — with cumulative dose — see a doctor immediately if jaundice occurs
• Pulmonary toxicity / methotrexate lung — see a doctor immediately
• Myelosuppression / pancytopenia — CBC monitoring is essential — see a doctor immediately if unusual bleeding/bruising occurs
• Severe mucositis
• Teratogenicity — absolutely contraindicated in pregnancy
• Opportunistic infections (due to reduced immunity)

13. Drug Interactions (Dawaon ke sath reaction)

• NSAIDs (Ibuprofen, Diclofenac, Naproxen) — reduce kidney excretion of MTX — toxicity may increase; inform your doctor
• Trimethoprim / Co-trimoxazole (antibiotic) — additive folate antagonism — serious myelosuppression
• Proton pump inhibitors (Omeprazole etc.) — reduce MTX clearance — levels may rise
• Penicillins (ampicillin etc.) — reduce MTX excretion
• Live vaccines — CONTRAINDICATED
• Alcohol — hepatotoxicity risk increases greatly

14. When to See Doctor (Kab doctor ke paas jayein)

• Shortness of breath or dry cough
• Severe mouth ulcers or pain — contact a doctor immediately
• Unusual bruising, bleeding, or paleness
• Jaundice (piliya) or abdominal pain (hepatotoxicity)
