Methotrexate
Methoblastin
Methoblastin, with methotrexate as its active component, is an FDA-approved medication for various cancers and autoimmune conditions like rheumatoid arthritis and psoriasis. It comes in 2.5 mg and 10 mg tablets, taken once weekly, with dosages tailored to the specific condition. Common side effects include nausea and mouth sores, while serious effects can involve liver damage. It’s crucial to avoid alcohol and monitor for interactions with other medications. Pregnant women should not use Methoblastin due to the risk to the unborn baby. Proper storage and regular medical check-ups are essential for safe use.
Product Overview
Methoblastin, containing the active ingredient methotrexate, is a versatile medication used for treating various types of cancer and non-cancerous conditions. In cancer treatment, it is employed for acute lymphoblastic leukemia (ALL), non-Hodgkin lymphoma (NHL), osteosarcoma, breast cancer, and more, often in combination with other chemotherapy agents. Methotrexate works by inhibiting dihydrofolate reductase, a key enzyme in DNA synthesis, thereby slowing down the rapid growth of cancer cells. For non-cancer conditions like rheumatoid arthritis and psoriasis, methotrexate is believed to suppress an overactive immune system and reduce inflammation, although its exact mechanism is not fully understood.
Methoblastin is available in tablet form with strengths of 2.5 mg and 10 mg. The dosage varies depending on the condition being treated. For rheumatoid arthritis, the typical starting dose is 7.5 mg once per week, while for cancer treatment, doses are much higher and tailored to the individual’s needs. It is important to take Methoblastin exactly as prescribed by a healthcare provider, usually once a week, and to have regular check-ups to monitor progress and side effects.
Common side effects of Methoblastin include nausea, stomach pain, and mouth sores, while serious side effects can include liver damage and low blood cell counts. Patients should be cautious of potential interactions with other medications and avoid alcohol to reduce the risk of liver damage. Special precautions should be taken by pregnant women or those planning to become pregnant, as methotrexate can harm an unborn baby. In case of a missed dose or overdose, it is crucial to follow medical advice. Proper storage of Methoblastin at room temperature and away from moisture is essential for maintaining its effectiveness.

[Note: Remember, these recommendations may vary from person to person. Discuss it with your doctor, and they’ll customize your dosage accordingly.]
How to Take It?
- Always take Methoblastin exactly as prescribed by your healthcare provider. The dosage and frequency are specific to your condition and response to treatment.
- Methoblastin is often taken once a week, not daily. Make sure you understand which day of the week you are supposed to take your medication.
- Take the tablets with a full glass of water. Swallow the tablets whole; do not crush, break, or chew them.
- You can take Methoblastin with or without food, based on your doctor’s advice. Some people find that taking it with food helps reduce stomach upset.
- If you are taking other medications or supplements, ensure they are not taken at the same time as Methoblastin to avoid interactions.
- Have regular check-ups with your doctor to monitor your progress and any side effects.
- Dispose of any unused or expired medication properly. Do not flush it down the toilet or throw it in the trash.
[Note: Your doctor will decide the right amount for you based on your condition, following guidelines and studies on the drug. They’ll adjust it as needed over time.]
How Does Methoblastin Work?
- In Cancer Treatment: Methotrexate inhibits dihydrofolate reductase, a crucial enzyme for DNA synthesis and cell growth. This action slows down the rapid development of cancer cells, helping to prevent the spread of cancer.
- In Non-cancerous Conditions: The exact mechanism of methotrexate in treating conditions like rheumatoid arthritis and psoriasis is not fully understood. However, it is believed that at lower doses, methotrexate suppresses an overactive immune system. In the case of psoriasis, it may also slow down the excessive growth of skin cells.

Frequently Asked Questions
What medications should I avoid while taking methotrexate?
While on methotrexate, it’s important to avoid or use caution with medications that can interact with it, as some can increase the risk of side effects. These medications include certain antibiotics like amoxicillin and doxycycline, heartburn medications such as omeprazole (Prilosec), and NSAIDs like ibuprofen (Advil). Additionally, folic acid supplements may reduce the effectiveness of methotrexate in treating cancer, although they are beneficial in preventing side effects when methotrexate is used for non-cancerous conditions. Your healthcare team will review your medications before you start methotrexate to ensure their safety. Avoid beginning any new medications during treatment without consulting your healthcare provider.
Can I take methotrexate if I have kidney issues?
It depends on the function of your kidneys. Methotrexate is primarily eliminated from the body through the kidneys. If your kidneys are not functioning properly, methotrexate can accumulate in your body, increasing the risk of side effects. Additionally, methotrexate can potentially cause kidney damage. It’s important to discuss with your healthcare provider whether methotrexate is safe for you if you have kidney problems. Your provider will monitor your kidney function with regular lab tests during your treatment.
Is methotrexate safe during pregnancy?
Methotrexate is not safe to take during pregnancy. Animal studies and the mechanism of action of the medication suggest that it can harm an unborn baby. If you or your partner are capable of becoming pregnant, it is important to use effective contraception while taking methotrexate. Continue using birth control for 6 months after the last dose for females or for 3 months after the previous dose for males. Inform your healthcare team immediately if you or your partner becomes pregnant while taking methotrexate.
Is methotrexate classified as a chemotherapy drug?
Yes, methotrexate is considered a chemotherapy drug because it targets and destroys rapidly dividing cells. It works by inhibiting a protein essential for cell growth and division, effectively killing cancer cells. However, methotrexate can also affect healthy, fast-growing cells in the body, leading to side effects such as nausea, diarrhea, and mouth sores, especially when used at higher doses for cancer treatment. It’s important to note that methotrexate is also used at lower doses to manage autoimmune conditions like rheumatoid arthritis and psoriasis, where the risk of chemotherapy-related side effects is lower.
