Mitotane Medication: Uses, Side Effects & Adrenal Cancer Treatment
Introduction: Key Points About Mitotane Medication
Mitotane is a medication primarily prescribed to treat specific types of adrenal gland cancers, such as adrenocortical carcinoma. It works by targeting and reducing the activity of the adrenal glands, helping to manage symptoms and slow the progression of the disease. This medication is typically recommended when other treatments have proven ineffective or as part of a comprehensive treatment plan for adrenal cancer. Always consult your healthcare provider to determine whether Mitotane is the right option for your condition.
Medications in the Drug Class: Mitotane
Lysodren (Mitotane)
The generic name of a medication refers to its standard, non-branded designation. In this case, “Mitotane” is the generic name, listed alongside the brand name “Lysodren.” Both the generic and brand-name versions of this drug are designed to serve the same purpose: treating adrenal gland cancers, such as adrenocortical carcinoma.
How Mitotane Works: Mechanism of Action
Mitotane works by selectively targeting the adrenal cortex, which is the outer layer of the adrenal glands responsible for producing hormones like cortisol. It disrupts the normal function of adrenal cells, ultimately leading to their destruction. This process reduces the production of adrenal hormones, which is particularly beneficial for managing hormone-producing adrenal tumors. Unlike many other cancer treatments, Mitotane specifically affects adrenal tissue, making it a targeted therapy for adrenal-related conditions. There are no significant differences in how the brand-name and generic versions of this medication function.
Benefits of Mitotane Treatment
Mitotane is primarily used to treat adrenocortical carcinoma, a rare but aggressive form of cancer that affects the adrenal glands. It is especially effective for patients whose tumors produce excessive hormones, as it helps regulate hormone levels and alleviate related symptoms. Mitotane is often preferred over other treatment options for adrenal cancer due to its targeted action on adrenal tissue, which minimizes its effects on other parts of the body. Additionally, it can be combined with surgery or other therapies to enhance treatment outcomes.

Potential Side Effects of Mitotane Medication
Like all medications, Mitotane may cause side effects. It is important to understand these potential effects and discuss any concerns with your healthcare provider before beginning treatment. Below is a list of possible side effects, starting with the most common. Where available, percentages are included to indicate how frequently these side effects occur, along with scenarios in which certain effects may be more likely.
Common Side Effects (≥1%)
- Nausea and Vomiting (40-60%): These are among the most frequently reported side effects. Patients with a history of gastrointestinal sensitivity may be at a higher risk of experiencing these symptoms.
- Diarrhea (30-40%): Loose stools are common, particularly during the initial weeks of treatment. Staying hydrated and maintaining a balanced diet can help manage this symptom.
- Fatigue (20-30%): Many patients report feeling unusually tired or weak. This side effect may be more pronounced in individuals with pre-existing adrenal insufficiency.
- Dizziness (10-15%): Some patients experience lightheadedness or difficulty maintaining balance. This may be worsened by dehydration or low blood pressure.
- Skin Rash (5-10%): Mild to moderate skin irritation or rashes can occur. Patients with a history of skin sensitivity may be more susceptible to this side effect.
- Loss of Appetite (5-10%): A reduced appetite is a common complaint, which can sometimes lead to unintended weight loss.
Less Common Side Effects (<1%)
Less frequently reported side effects include confusion, headache, depression, abdominal pain, muscle weakness, blurred vision, hair thinning, and menstrual irregularities. While these are rare, it is important to inform your healthcare provider if they occur.
Severe Side Effects
Severe side effects are uncommon but require immediate medical attention. These include:
- Adrenal Insufficiency: Mitotane suppresses adrenal gland function, which can result in dangerously low cortisol levels. Symptoms may include severe fatigue, low blood pressure, and fainting.
- Neurological Effects: In rare cases, Mitotane can cause confusion, memory problems, or difficulty concentrating. These symptoms may indicate toxicity and should be addressed promptly.
- Liver Toxicity: Elevated liver enzymes have been reported in some patients. Symptoms such as yellowing of the skin or eyes (jaundice) should prompt urgent medical evaluation.
If you experience any severe side effects, stop taking the medication and contact your healthcare provider immediately. Our telemedicine providers are available to assist you with any concerns or questions you may have.
Drug-to-Drug Interactions with Mitotane
Mitotane, an essential medication for treating adrenal cancer, can interact with a variety of drugs. These interactions may alter the effectiveness of either Mitotane or the other medications, and in some cases, increase the risk of side effects. Below are some common drug interactions to be aware of:
Warfarin (blood thinner): Mitotane may decrease the effectiveness of warfarin, which could increase the risk of blood clots. To manage this, regular monitoring of INR (a measure of blood clotting) is highly recommended throughout Mitotane treatment.
Phenytoin (anti-seizure medication): Mitotane can lower the levels of phenytoin in the blood, potentially reducing its ability to control seizures. Adjustments to the phenytoin dosage may be necessary to maintain seizure control.
Spironolactone (diuretic): Spironolactone may interfere with Mitotane’s effects on the adrenal glands, potentially reducing its effectiveness in treating adrenal cancer. This interaction should be carefully managed by your healthcare provider.
Hormonal Contraceptives: Mitotane can decrease the effectiveness of hormonal birth control methods, including pills, patches, and implants. Women taking Mitotane should discuss alternative contraceptive options with their healthcare provider to ensure reliable pregnancy prevention.
CYP3A4 Substrates: Mitotane induces liver enzymes, particularly CYP3A4, which are responsible for metabolizing many drugs, such as statins, benzodiazepines, and certain antidepressants. This can lead to lower levels of these medications in the bloodstream, potentially reducing their effectiveness. Dosage adjustments or alternative treatments may be required.
To ensure safe and effective treatment, it is crucial to inform your healthcare provider about all medications, supplements, and herbal products you are currently using before starting Mitotane. Our telemedicine providers are available to review your medication list and help minimize the risk of potential interactions.
Precautions and Contraindications for Mitotane Treatment
Before starting Mitotane, a widely used treatment for adrenal cancer, it is important to evaluate specific precautions and contraindications to ensure the medication is safe and appropriate for you.
Precautions
Pregnancy: Mitotane is not recommended during pregnancy due to its potential to harm the developing fetus. Women of childbearing age should use reliable contraception while undergoing treatment with Mitotane.
Breastfeeding: It is not yet known whether Mitotane passes into breast milk. As a precaution, breastfeeding is generally discouraged while taking this medication to avoid potential risks to the infant.
Adrenal Insufficiency: Because Mitotane suppresses adrenal gland function, patients may require supplemental corticosteroids to maintain adequate hormone levels during treatment. Your healthcare provider will monitor and manage this as needed.
Liver Function: Mitotane has the potential to cause liver toxicity. Regular monitoring of liver enzymes is recommended, particularly for patients with pre-existing liver conditions, to detect and address any issues early.
Neurological Conditions: Patients with neurological disorders should use Mitotane with caution, as it may exacerbate symptoms such as confusion, dizziness, or other neurological side effects. Close monitoring by your healthcare provider is advised.
Contraindications
Allergy to Mitotane: Patients with a known allergy or hypersensitivity to Mitotane or any of its components should not take this medication.
Severe Liver or Kidney Disease: Since Mitotane is metabolized by the liver and excreted by the kidneys, patients with severe liver or kidney impairment are at a higher risk of toxicity. For this reason, Mitotane is not recommended for individuals with significant dysfunction in these organs.
Conclusion: Understanding Mitotane and Its Role in Adrenal Cancer Treatment
Mitotane is a highly effective medication widely used in the treatment of adrenal cancer, particularly adrenocortical carcinoma, as well as other conditions affecting the adrenal glands.
