melphalan
Summary
Melphalan is used to treat multiple myeloma, which is a cancer of plasma cells, and ovarian cancer. It helps reduce cancer symptoms and improve survival rates.
Melphalan works by damaging the DNA of cancer cells, which prevents them from growing and dividing. It belongs to a class of drugs called alkylating agents, which form cross-links in DNA strands.
Melphalan is usually taken as a single dose or divided into smaller doses over a few days. The dose varies based on the condition being treated and individual response. It is often taken long-term for chronic conditions.
Common side effects of Melphalan include fatigue, which is extreme tiredness, nausea, which is feeling sick to your stomach, and low blood cell counts, which can lead to infections and anemia.
Melphalan can suppress bone marrow, which is where blood cells are made, increasing infection risk. It should not be used if you have a known allergy to it. Regular blood tests are needed to monitor safety.
Indications and Purpose
How does Melphalan work?
Melphalan works by interfering with the DNA of cancer cells, preventing them from growing and dividing.

Warnings and Precautions
Can I take Melphalan with other prescription drugs?
Melphalan can interact with other medications, increasing the risk of side effects. For example, combining it with other chemotherapy drugs can enhance bone marrow suppression, which is a condition where your body can't produce enough blood cells. This increases the risk of infections and bleeding. Always inform your doctor about all the medications you're taking to avoid harmful interactions. They can adjust your treatment plan to ensure safety and effectiveness.
Can Melphalan be taken safely while breastfeeding?
Melphalan is not recommended while breastfeeding. There is limited information on whether it passes into breast milk, but it could potentially harm the nursing infant. The medication might affect the baby's developing cells. We don't know how it might impact milk production. If you're taking Melphalan and want to breastfeed, discuss safer medication options with your doctor. They can help you find a treatment plan that allows you to nurse safely.
Can Melphalan be taken safely while pregnant?
Melphalan is not recommended during pregnancy. It can harm the developing baby, as it affects rapidly dividing cells, which include fetal cells. There is limited information on its use in pregnant women, but the risks are significant. If you're pregnant or planning to become pregnant, talk with your doctor about safer treatment options. They can help create a plan that protects both you and your baby during this important time.
Does Melphalan have adverse effects?
Adverse effects are unwanted reactions to a medication. Melphalan can cause several adverse effects, including nausea, vomiting, and low blood cell counts.

If you notice any new or worsening symptoms, contact your doctor immediately. They can help manage these effects and adjust your treatment if necessary to ensure your safety.
Does Melphalan have any safety warnings?
Yes, Melphalan has important safety warnings. It can suppress bone marrow, which is where blood cells are made, leading to low blood cell counts. This increases the risk of infections, bleeding, and anemia, which is a lack of red blood cells. Regular blood tests are needed to monitor your blood cell levels. Not following these safety warnings can lead to serious health issues. Always adhere to your doctor's advice and report any unusual symptoms immediately.
Is it safe to drink alcohol while taking Melphalan?
It's best to avoid alcohol while taking Melphalan. Alcohol can increase the risk of liver damage and worsen side effects like nausea and vomiting.
