Cisplatin is a platinum-based chemotherapy medication that has been a cornerstone of cancer treatment since 1978. This powerful anticancer drug is commonly used to treat various solid tumors including testicular, ovarian, bladder, head and neck, lung, and cervical cancers.
Cisplatin has demonstrated remarkable effectiveness, particularly in testicular cancer where it has significantly improved survival rates and cure rates.
What is Cisplatin?
Cisplatin is a coordination complex of platinum with the chemical formula cis-[Pt(NH3)2Cl2]. It belongs to a class of chemotherapy drugs called alkylating agents and contains the metal platinum, which gives it its unique anticancer properties.
The drug is administered exclusively through intravenous injection as a sterile solution and requires careful monitoring during treatment.
What Are the Uses of Cisplatin Injection?
Cisplatin Injection offers significant therapeutic benefits for cancer patients, particularly when used in combination with other chemotherapy drugs.
The drug has shown remarkable efficacy in treating multiple cancer types and has become an essential component of many treatment protocols.
Conditions Cisplatin Treats
Cisplatin is FDA-approved to treat several types of cancer:
Testicular cancer - Often used in combination with bleomycin and etoposide
Ovarian cancer - Frequently combined with cyclophosphamide or other agents
Bladder cancer - Used as both single-agent and combination therapy
Head and neck cancers - Including esophageal cancer
Lung cancer - Both small cell and non-small cell types
Cervical cancer - Often combined with radiation therapy
Beyond its primary indications, cisplatin is also used to treat:
Mesothelioma - All four subtypes including pleural, peritoneal, pericardial, and testicular
Brain tumors - Including certain types of neuroblastoma
Sarcomas and lymphomas - Various subtypes respond to cisplatin-based regimens
How Does Cisplatin Work (Mechanism of action)?
Cisplatin's mechanism of action involves a complex process that ultimately leads to cancer cell death. The drug works by interfering with DNA replication and repair mechanisms.
Once administered intravenously, cisplatin remains stable in the bloodstream due to high chloride concentrations. Upon entering cancer cells, the drug undergoes aquation, where water molecules slowly replace chloride ions. This process creates an electrophilic compound that has a strong affinity for DNA.
The activated cisplatin then binds to the N7 reactive centers on purine bases, particularly guanine residues in DNA. This binding creates DNA cross-links between adjacent guanine molecules, which prevents DNA replication and transcription.
The DNA damage triggers cellular repair mechanisms, but when repair fails, the cell undergoes programmed cell death (apoptosis).
Cisplatin Dosage
Cisplatin dosage must be carefully calculated based on the patient's clinical condition, body surface area, renal function, and response to treatment. The drug requires precise administration to maximize therapeutic benefits while minimizing toxicity.
Typical Dosage Instructions
Standard Adult Dosing Regimens:
Metastatic Testicular Cancer: The standard dose is 20 mg/m² IV daily for 5 days, repeated every 3 weeks in combination with bleomycin and etoposide.
Advanced Bladder Cancer: 50-70 mg/m² IV per cycle every 3-4 weeks, with initial doses of 50 mg/m² recommended for heavily pretreated patients.
Metastatic Ovarian Cancer: 75-100 mg/m² IV per cycle every 4 weeks, typically combined with cyclophosphamide at 600 mg/m².
Pediatric use: Dosing regimens differ and should be referenced from specific protocols; cisplatin is not always recommended for children outside specialized settings.
Maximum dose per cycle is generally 100 mg/m².
Always refer to the specific treatment protocol and consult with oncology specialists for individualized dosing and modifications.
What Should I Do If I Miss a Dose?
If you miss a scheduled cisplatin dose, contact your doctor or pharmacist immediately for a new dosing schedule. Never attempt to double doses or self-adjust the timing, as cisplatin requires precise scheduling to maintain effectiveness and safety.
What Happens If an Overdose?
Cisplatin overdose is a serious medical emergency that requires immediate attention. Healthcare providers exercise extreme caution to prevent inadvertent overdosage, with special warnings for doses exceeding 100 mg/m²per cycle.
Symptoms of Overdose
Overdose symptoms may include severe kidney damage, hearing loss, severe nausea and vomiting, and dangerous drops in blood cell counts. Seek emergency medical attention immediately if overdose is suspected.
What to Avoid
Avoid aluminum-containing equipment during preparation and administration, as aluminum reacts with cisplatin causing precipitation and loss of potency.
Get a second opinion from trusted experts and makeconfident, informed decisions.
Cisplatin is associated with significant side effects that require careful monitoring and management. While effective against cancer, the drug can cause both common and serious adverse reactions that patients and healthcare providers must be prepared to address.
Common Side Effects
The most frequently reported cisplatin side effects include:
Nausea and vomiting - Often severe and requiring antiemetic medications
Temporary hair loss - Usually reversible after treatment completion
Fatigue and weakness - Can persist for weeks after treatment
Diarrhea - May require dietary modifications and medications
Decreased sweating - May affect temperature regulation
Serious but Rare Side Effects
More serious adverse reactions that require immediate medical attention include:
Kidney damage (nephrotoxicity) - Can be permanent and dose-limiting
Hearing loss (ototoxicity) - May be irreversible, especially high-frequency hearing
Peripheral neuropathy - Numbness and tingling in hands and feet
Blood disorders - Including anemia, neutropenia, and thrombocytopenia
Allergic reactions - Can include anaphylaxis, especially with repeated doses
Heart rhythm changes - Including fast, slow, or irregular heartbeats
Patients should consult their doctor immediately if any symptoms worsen or if they experience signs of serious side effects such as unusual bleeding, vision changes, hearing problems, or symptoms of infection.
Precautions and Warnings
Cisplatin carries several black box warnings due to its potential for serious toxicity. Healthcare providers must carefully evaluate patients before treatment and monitor closely throughout therapy.
Who Should Avoid This Medicine
Patients with the following conditions should not receive cisplatin:
Known allergies to cisplatin or other platinum compounds
Severe kidney disease - Due to high risk of nephrotoxicity
Severe hearing impairment - Risk of further hearing loss
Severe bone marrow suppression - Increased infection and bleeding risk
Conditions Where Caution is Needed
Special monitoring is required for patients with:
Mild to moderate kidney disease - Requires dose adjustments
Mineral imbalances - Electrolyte monitoring essential
Infection Prevention - Wash hands thoroughly and avoid activities that risk cuts or bruises.
Fertility and Pregnancy - Cisplatin may affect fertility and harm unborn children. Reliable birth control is recommended during and after treatment.
Breastfeeding - Not recommended as Cisplatin passes into breast milk and may harm the infant.
Are There Any Age Restrictions for Using Cisplatin?
While cisplatin can be used in pediatric patients, special considerations apply. Children may be more susceptible to hearing loss and kidney damage. Elderly patients also require careful monitoring due to age-related decline in kidney function.
Alcohol or Food Interactions
Patients should avoid alcohol during cisplatin treatment as it may increase the risk of kidney damage and interfere with the body's ability to fight infection. Adequate hydration is essential; patients should increase their fluid intake as directed by their healthcare team.
Possible Interactions with Other Medications (Drug Interactions)
Cisplatin can interact with numerous medications, potentially increasing toxicity or reducing effectiveness. Healthcare providers must carefully review all medications before starting treatment.
Overview of Drug Interactions
Nephrotoxic drugs pose the highest risk when combined with cisplatin. These include aminoglycoside antibiotics, amphotericin B, and certain diuretics, which can increase kidney damage risk.
Ototoxic medications such as loop diuretics and aminoglycosides can increase the risk of hearing loss when used with cisplatin.
Phenytoin levels may be affected by cisplatin, requiring dose adjustments and monitoring of anticonvulsant therapy.
Possible Impact When Combined with Supplements and Herbal Products
Patients should inform their healthcare team about all supplements and herbal products, as some may interfere with cisplatin's effectiveness or increase side effects. Antioxidant supplements may theoretically reduce cisplatin's anticancer activity, though clinical evidence is limited.
How Should Cisplatin Be Stored?
Proper storage of cisplatin is critical for maintaining drug stability and preventing degradation. Healthcare facilities must follow strict storage protocols to ensure patient safety and drug efficacy.
Recommended Storage Temperature for Cisplatin
Cisplatin injection should be stored at controlled room temperature between 15°C to 25°C (59°F to 77°F). The drug must not be refrigerated, as cold temperatures can cause precipitation and loss of potency.
What Happens If Cisplatin Is Not Stored Properly?
Improper storage can lead to drug precipitation, loss of potency, and potential safety hazards. Refrigeration or freezing will cause the active ingredient to precipitate out of solution, making the drug ineffective.
The drug should be protected from light and kept in its original container until use. Any unused portions must be discarded properly according to hazardous drug disposal protocols, and the medication must be kept away from children and pets at all times.

Cisplatin is used to treat head and neck cancer, testicular cancer, ovarian cancer, cervical cancer, breast cancer, bladder cancer, esophageal cancer, lung cancer, mesothelioma, and brain tumors.
Carboplatin is used to treat a number of forms of cancer, often as an alternative to cisplatin due to its reduced toxicity profile.
Platinum-based chemotherapy drugs are among the most potent and widely used anticancer drugs. They have toxic side effects, however, and tumors can become resistant to them. Cisplatin is the most common platinum chemotherapy drug.
Cisplatin is one of the most effective anti-cancer agents widely used in the treatment of solid tumors. It is generally considered to be a cytotoxic drug that kills cancer cells by damaging DNA and inhibiting DNA synthesis.
Cisplatin or cis-diamminedichloroplatinum (II) is a well-known chemotherapy drug. It has been used to treat a number of human cancers including bladder, head and neck, lung, ovarian, and testicular cancers.
Nausea and vomiting usually begin within 1 to 4 hours of treatment and last up to 24 hours. Various levels of vomiting, nausea, and/or anorexia may persist for up to 1 week after treatment.
Cisplatin is a potent and valuable chemotherapy agent used to treat a wide range of malignancies. Renal tubular dysfunction and cumulative impairment of renal function, as evidenced by a decrease in the glomerular filtration rate (GFR), may be dose-limiting.
Cisplatin is unique in that it can cause late cardiovascular complications such as hypertension, left ventricular hypertrophy, myocardial ischemia, and myocardial infarction (MI) for up to 10 to 20 years after remission of metastatic testicular cancer.
Cisplatin injection is commonly used as a chemotherapy medication to treat various types of cancer. It is particularly effective in managing testicular, ovarian, bladder, and lung cancers, and is often administered in combination with other cancer-fighting drugs. By interfering with the DNA in cancer cells, cisplatin prevents them from multiplying and helps shrink tumors. Its strong antitumor activity has made it a cornerstone in many chemotherapy protocols.
Cisplatin 50 mg refers to a specific dosage strength of the drug and is typically used during chemotherapy cycles for cancers like testicular cancer, ovarian cancer, cervical cancer, and non-small cell lung cancer. The 50 mg dose is usually diluted and administered intravenously under strict medical supervision, based on the patient’s body surface area, type of cancer, and overall treatment plan. The exact dosage and frequency depend on individual patient factors and the cancer being treated.
Cisplatin and carboplatin are not exactly the same, but they belong to the same class of chemotherapy drugs known as platinum-based compounds. While both are used to treat similar types of cancers, such as ovarian and lung cancer, they differ in their chemical structure, toxicity profile, and side effects. Cisplatin is generally more potent but has a higher risk of causing kidney damage, nausea, and vomiting. Carboplatin, on the other hand, tends to have fewer kidney-related side effects and is often used as an alternative when patients cannot tolerate cisplatin.
Yes, cisplatin chemotherapy can lead to hair loss in some patients, although the severity varies. Hair loss occurs because the drug targets rapidly dividing cells, and hair follicles fall into that category. However, not everyone experiences significant hair loss, and it often depends on the dose, treatment duration, and whether cisplatin is combined with other chemotherapy agents. In most cases, hair usually grows back after the treatment ends.
