Dabrafenib comes in capsule form and should be taken by mouth. Here’s how to use it:

1. Follow your doctor’s instructions: Always take the medication exactly as prescribed. Do not take more or less than directed.
2. Take with or without food: You can take dabrafenib with or without food, but it’s important to take it at the same time each day.
3. Swallow the capsules whole: Do not crush, chew, or open the capsules. This could affect how the medication works.
4. Missed Dose: If you miss a dose, take it as soon as you remember unless it’s almost time for your next dose. If it’s almost time, skip the missed dose—do not take two doses at once.

If you have any questions or concerns about how to take the medication, talk to your doctor or pharmacist.

Dabrafenib belongs to a class of medications called BRAF inhibitors. It specifically targets the BRAF V600 mutation, which is an abnormal change in the BRAF gene that can cause cells to grow and divide uncontrollably, leading to cancer.

Here’s how dabrafenib works:

• Inhibiting the BRAF Protein: Dabrafenib blocks the mutated BRAF protein, which slows down or stops the abnormal cell growth that occurs in some cancers.
• Preventing Cancer Cell Division: By targeting the mutation, dabrafenib helps prevent the cancer cells from multiplying and spreading.
• Combination with Trametinib: When used with trametinib, dabrafenib can more effectively block cancer cell growth by targeting multiple parts of the pathway that leads to cancer cell proliferation.

Together, these treatments help slow the growth of certain cancers and improve outcomes for patients with the BRAF V600 mutation.

Like all medications, dabrafenib can cause side effects, though not everyone will experience them. Some common side effects include:

• Fever or Chills: Many people may experience fever or chills, especially during the first few weeks of treatment.
• Skin Rash or Blisters: Dabrafenib can cause skin issues, including rashes or blisters. Make sure to tell your doctor if you notice any changes to your skin.
• Fatigue or Weakness: Feeling tired or weak is a common side effect, especially during the early stages of treatment.
• Nausea or Vomiting: Some people may experience stomach upset, nausea, or vomiting.

Serious side effects (which require immediate medical attention) include:

• Severe Skin Reactions: In rare cases, dabrafenib can cause severe skin reactions such as blisters, peeling skin, or a rash that can lead to complications.
• Heart Problems: Dabrafenib may cause heart-related issues, such as heart rhythm problems or heart failure.
• Liver Issues: Symptoms of liver problems may include yellowing of the skin or eyes (jaundice), dark urine, or stomach pain.

If you experience any severe side effects, contact your doctor immediately.

Before taking dabrafenib, be aware of the following warnings and precautions:

• Skin Problems: Dabrafenib can cause severe skin reactions. Your doctor may monitor you closely, especially during the first few weeks of treatment.
• Heart Issues: If you have a history of heart problems, let your doctor know, as dabrafenib may affect your heart health.
• Liver Function: Your doctor will monitor your liver function during treatment. If you have liver problems, dabrafenib may not be suitable for you.
• Pregnancy and Breastfeeding: Dabrafenib may not be safe during pregnancy or while breastfeeding. Discuss your options with your doctor if you are pregnant, planning to become pregnant, or breastfeeding.
• Other Health Conditions: Let your doctor know if you have other health issues, such as eye problems, as they may need to adjust your treatment plan.

Dabrafenib can interact with other medications, which can either increase the risk of side effects or affect how well the drug works. Some potential interactions include:

• Other Cancer Medications: Using dabrafenib with other cancer treatments may increase the risk of side effects like infections, bleeding, or liver problems.
• Certain Antifungals and Antibiotics: These can affect how dabrafenib works in your body, leading to either increased or decreased drug levels.
• Medications Affecting Liver Enzymes: Drugs that change the way your liver processes medications may interfere with dabrafenib’s effectiveness or increase the risk of side effects.

Always tell your doctor about all other medications you’re taking, including over-the-counter drugs and herbal supplements, to avoid harmful interactions.

The typical dosage for dabrafenib is:

• For Melanoma or Non-Small Cell Lung Cancer: 150 mg taken twice a day (morning and evening).
• For Other Cancers: Your doctor will determine the exact dosage based on your specific condition and response to treatment.

Always follow your doctor’s instructions regarding dosage.

Dabrafenib is available only by prescription, and you should take it under the supervision of a healthcare provider. Your doctor will evaluate your condition and determine if dabrafenib is appropriate for you based on your cancer type and genetic profile (BRAF mutation).

If you have any questions or concerns about using dabrafenib, speak with your healthcare provider.
