Molecule Description
Bleomycin is a medicine used to treat cancer. It belongs to a group of medicines that damage cancer cells and stop them from growing and multiplying.
Bleomycin is indicated in the management of certain cancers, including prostate, breast, lymphoma, melanoma, and cancers of the head, neck, and lungs.
Common side effects of Bleomycin include fever, chills, skin hyperpigmentation, stomatitis, loss of appetite, and hair thinning.
Contact your doctor immediately if you experience signs of an allergic reaction (such as a skin rash, itching, or swelling of the face, lips, or throat), severe dry cough, progressive shortness of breath, sudden fever, or chest pain.
Bleomycin is administered by healthcare professionals via intravenous (IV), intramuscular (IM), subcutaneous (SC), or intrapleural route, depending on the indication and prescribed treatment protocol.
Bleomycin is a prescription-only medicine and should be used strictly under medical supervision. The treatment plan is decided by the treating doctor based on the condition being treated, your body response and the other medicines you are receiving. Do not change, stop or repeat a dose on your own.
Before starting Bleomycin, tell your doctor about all your existing medical conditions, especially heart, liver or kidney problems, and about every medicine, vitamin, supplement and herbal product you take. Tell your doctor if you are pregnant, planning a pregnancy or breastfeeding. Regular blood tests and clinical check-ups are usually needed during treatment so that side effects are picked up early.

Other General Warnings
Talk to your doctor if
- Consult your doctor if you:
- Have a history of lung disease, kidney dysfunction, or prior chest radiation.
- Develop persistent dry cough, chest tightness, or fever following your injection.
- Are scheduled for surgery or a procedure requiring anaesthesia or supplemental oxygen and have previously received bleomycin.
- Monitor for dry cough, fever, or shortness of breath and report these symptoms immediately.
- Inform your doctor of prior bleomycin therapy before any procedure requiring supplemental oxygen or anaesthesia.
- Your doctor may arrange lung function assessment before and during treatment, depending on your treatment regimen and individual risk factors.
- Healthcare personnel dispose of unused solution or empty vials following standard clinical cytotoxic waste procedures.
Mode of Action
How Does It Work?
Bleomycin works by damaging the DNA of cancer cells, especially cells that are actively dividing. It attaches to DNA and causes breaks in the DNA strands, preventing cancer cells from copying their DNA and multiplying. As a result, damaged cancer cells stop growing and eventually die, helping slow tumour growth.
Interactions
Interactions with other medicines
- Oxygen: High oxygen levels, especially during surgery or anaesthesia, may increase the risk of lung damage after bleomycin treatment. Always tell your doctor or anaesthetist if you have received bleomycin.
- Cisplatin: May increase bleomycin levels in the body and raise the risk of side effects, including lung problems.
- G-CSF medicines such as filgrastim: May increase the risk of lung toxicity when used with bleomycin. Your doctor will monitor you closely.
- Tell your doctor about all medicines, vitamins, supplements, and herbal products you take.
Interactions with food items
Since Bleomycin is administered parenterally (bypassing the digestive tract), food intake does not impact drug absorption.
Dosage
Overdose
Because Bleomycin is calculated and administered by healthcare professionals following chemotherapy protocols, overdose is uncommon. In case of overdose, supportive and symptomatic care, including close monitoring for lung toxicity, is provided.
Missed a Dose
Because Bleomycin is timed according to a certain chemotherapy protocol, report any delayed or missed dose to your oncology team immediately for review.
