Methotrexate is a medication used to treat various conditions, including cancer, autoimmune diseases, and certain skin conditions. It belongs to a class of drugs called antimetabolites, which work by interfering with the growth of cells.
Let's break it down:
1. **Cancer Treatment**: Methotrexate is commonly used to treat different types of cancer, including leukemia, lymphoma, and breast cancer. It works by stopping cancer cells from growing and spreading. Methotrexate can be given in different ways, such as by mouth (in the form of tablets), injection into a vein (intravenously), or injection into the muscle (intramuscularly).
2. **Autoimmune Diseases**: Methotrexate is also used to treat autoimmune diseases, where the body's immune system attacks healthy tissues. Conditions like rheumatoid arthritis, psoriasis, and inflammatory bowel disease (IBD) can be managed with methotrexate. In these cases, methotrexate helps reduce inflammation and suppresses the immune system's activity.
3. **How It Works**: Methotrexate interferes with a process in the body called folic acid metabolism. Folic acid is a B vitamin that's essential for cell growth and reproduction. Methotrexate blocks the action of an enzyme called dihydrofolate reductase, which is needed for cells to use folic acid. Without this enzyme, cells can't make DNA or RNA, which are essential for cell growth and division. As a result, cancer cells and rapidly dividing cells in autoimmune diseases are affected the most.
4. **Dosage and Administration**: The dosage and administration of methotrexate depend on the condition being treated, the patient's weight, and other factors. It's crucial to take methotrexate exactly as prescribed by the doctor. Missing doses or taking too much can lead to serious side effects.
5. **Side Effects**: Methotrexate can cause various side effects, including nausea, vomiting, diarrhea, mouth sores, fatigue, and hair loss. It can also affect the bone marrow, leading to a decrease in the number of blood cells. This can increase the risk of infections, anemia, or bleeding. Regular blood tests are often required to monitor for these side effects.
6. **Precautions**: It's essential to take precautions while using methotrexate. For example, methotrexate can harm an unborn baby, so it's crucial for pregnant women or those planning to become pregnant to avoid taking it. Additionally, methotrexate can interact with other medications, so it's important to inform the doctor about all medications, vitamins, and supplements being taken.
7. **Follow-Up Care**: Regular follow-up appointments with the doctor are necessary while taking methotrexate. These appointments allow the doctor to monitor the treatment's effectiveness, adjust the dosage if needed, and manage any side effects.
In summary, methotrexate is a versatile medication used to treat cancer, autoimmune diseases, and certain skin conditions. It works by interfering with cell growth and division, making it effective against conditions where cells grow and divide rapidly. However, it can cause various side effects, so it's crucial to use it under the guidance of a healthcare professional.

Methotrexate
Imagine your body is like a city, bustling with activity. In this city, cells are like the workers, and they need instructions to do their jobs properly. These instructions come from DNA, which is like a blueprint for building and repairing things in the city.
Now, when someone has cancer or an autoimmune disease, some cells start acting out. They grow too fast or attack healthy parts of the city. This is where methotrexate comes in.
Methotrexate is like a traffic cop. It stops those misbehaving cells in their tracks. It does this by blocking an important molecule called folic acid, which cells need to grow and divide.
By blocking folic acid, methotrexate slows down the growth of those troublemaking cells. It's like putting up roadblocks that prevent them from causing more damage to the city.
So, in simple terms, methotrexate works by putting the brakes on the out-of-control cells in your body, whether they're cancer cells or cells causing autoimmune diseases. This helps keep things in order and gives your body a chance to heal.
