ONCOTREX 7.5MG

# Methotrexate 7.5 mg ## Short Description **Methotrexate 7.5 mg** is a prescription medicine used in carefully controlled doses for certain **inflammatory, autoimmune and cancer-related conditions**. It belongs to a group of medicines called **antimetabolites** and, at low weekly doses, acts primarily as an immunomodulatory and anti-inflammatory medicine. Methotrexate may be prescribed for conditions such as **rheumatoid arthritis, psoriasis and psoriatic arthritis**, while higher or specially calculated doses may be used in certain cancers and other serious conditions. > **Very important:** For many inflammatory conditions, methotrexate is taken **ONCE WEEKLY, not daily**. Taking it every day by mistake can cause severe toxicity and may be fatal. --- ## Key Benefits * Helps reduce **inflammation and disease activity** in certain autoimmune conditions. * Can relieve **joint pain, swelling and stiffness** associated with rheumatoid arthritis. * Helps control moderate-to-severe **psoriasis** in selected patients. * May help manage **psoriatic arthritis**. * Can slow disease progression in some inflammatory joint diseases. * At appropriately selected doses, it can be used as part of treatment for certain **cancers and other serious medical conditions**. --- ## Uses / Indications Methotrexate 7.5 mg may be prescribed for: ### 1. Rheumatoid Arthritis Methotrexate is commonly used as a **disease-modifying antirheumatic drug (DMARD)** to reduce inflammation and slow progression of rheumatoid arthritis. ### 2. Psoriasis It may be used for moderate-to-severe psoriasis when other treatments are unsuitable or insufficient. ### 3. Psoriatic Arthritis Methotrexate may help reduce joint inflammation and symptoms associated with psoriatic arthritis. ### 4. Other Autoimmune or Inflammatory Conditions Specialists may prescribe methotrexate for selected inflammatory disorders when clinically appropriate. ### 5. Cancer Treatment Methotrexate is also an important medicine in oncology. However, **cancer treatment uses different dosing schedules and requires specialist supervision**. > The **7.5 mg strength does not mean that 7.5 mg is the correct dose for every condition**. Methotrexate dosing varies substantially according to the indication, formulation and patient factors. --- ## How It Works Methotrexate interferes with **folate-dependent cellular processes** and inhibits enzymes involved in folate metabolism and DNA synthesis. At low doses used for inflammatory diseases, methotrexate increases levels of certain compounds, including **adenosine**, which contributes to its anti-inflammatory effects and reduces excessive immune activity. At higher doses used in some cancers, methotrexate can interfere more strongly with DNA synthesis and cell replication. ### Simple Mechanism **Methotrexate → affects folate-dependent pathways → alters immune/inflammatory activity → reduces inflammation and abnormal cell growth.** --- ## Dosage & Administration > **Methotrexate must be taken exactly as prescribed. Never change the dose or frequency without medical advice.** ### For Rheumatoid Arthritis, Psoriasis and Other Inflammatory Conditions Methotrexate is commonly administered **once weekly**, usually on the same day each week. A healthcare professional may start treatment with a low dose and gradually adjust it according to: * Disease response * Blood test results * Kidney and liver function * Side effects * Other medicines being taken **7.5 mg is one commonly used tablet strength, not a universal weekly dose.** ### Folic Acid Doctors commonly prescribe **folic acid supplementation** alongside methotrexate for inflammatory conditions to help reduce certain adverse effects. The timing and dose should follow the prescriber's instructions. ### How to Take * Take the medicine on the **prescribed day only**. * Swallow tablets with water. * Follow the prescribed weekly schedule carefully. * Do not take extra tablets if symptoms do not improve. * Keep the medicine separate from daily medicines if this helps prevent accidental daily dosing. ### Missed Dose If you forget a weekly dose, contact your healthcare professional or follow the instructions provided with your prescription. **Do not take a double dose to make up for a missed dose.** ### Monitoring Regular monitoring may include: * Complete blood count (CBC) * Liver function tests * Kidney function tests * Other tests depending on your condition --- ## Side Effects ### Common Side Effects Possible side effects include: * Nausea * Vomiting * Diarrhea * Abdominal discomfort * Loss of appetite * Headache * Fatigue * Mouth ulcers * Mild hair thinning * Increased sensitivity to sunlight ### Serious Side Effects Methotrexate can cause serious toxicity, including: * Severe reduction in blood cells * Serious infections * Liver injury * Kidney injury * Lung inflammation or lung damage * Severe skin reactions * Gastrointestinal bleeding or ulceration Seek urgent medical attention if you develop: * Fever or signs of infection * Persistent cough or difficulty breathing * Severe mouth ulcers * Unusual bruising or bleeding * Yellowing of the skin or eyes * Severe abdominal pain * Severe weakness * Dark urine * Significant skin blistering or peeling --- ## Precautions & Warnings ### **Weekly Dosing Error – Critical Warning** For many inflammatory conditions, methotrexate is taken **once weekly**.
