Dyronib Tablets (Dasatinib): Targeted Cancer Therapy | For Treatment of Certain Types of Leukemia

Precautions

Dyronib Tablet contains dasatinib, a medicine used to treat certain types of blood cancers, including some forms of chronic myeloid leukaemia. It works by blocking specific proteins that help abnormal cells grow. Careful monitoring and following your specialist’s instructions are important throughout treatment.

Before You Start

• Share your medical history: Tell your doctor if you have heart, liver, or breathing problems, or a history of unusual bleeding.

• Mention all medicines: Inform your doctor about every medicine and supplement you take, especially blood thinners, anti-inflammatory medicines, and medicines for stomach acidity.

• Discuss pregnancy or breastfeeding: Seek specialist advice, as dasatinib may harm an unborn baby.

• Attend regular check-ups: Blood tests and other assessments help your doctor monitor how your body responds to treatment.

While Using It

• Follow the prescribed dose: Take Dyronib exactly as directed. Do not change the dose or stop treatment on your own.

• Watch for unusual bleeding: Report unexplained bruising, frequent nosebleeds, or blood in your urine or stools promptly.

• Notice swelling or breathing changes: New swelling, sudden weight gain, a persistent dry cough, or shortness of breath should be reported to your doctor.

• Keep an eye on your temperature: Contact your healthcare team if you develop a fever or signs of an infection.

• Check before taking new medicines: Some medicines, including certain acidity treatments, can affect how dasatinib works. Ask your doctor or pharmacist before adding anything new.

• Stay hydrated: Follow your healthcare team’s advice about fluid intake, particularly if you have other medical conditions.

When to Seek Medical Help

• Unusual bleeding: Seek prompt medical attention for persistent bleeding or black, tar-like stools.

• Breathing difficulties: Get urgent medical help for sudden or severe shortness of breath or chest pain.

• Heart-related symptoms: Seek immediate attention for a rapid or irregular heartbeat, fainting, or severe dizziness.

• Signs of infection: Report fever or worsening symptoms promptly, as treatment can affect blood cell counts.

Note:

Dyronib Tablet should be used under the supervision of a specialist. Keep up with scheduled blood tests and follow-up appointments, and report new or unusual symptoms rather than adjusting the dose yourself.

Interactions

Dyronib Tablets contain dasatinib, a medicine used to treat certain types of blood cancer. Some medicines, foods, and supplements can change how dasatinib works in the body or increase the chance of side effects. Knowing what to watch out for can help you discuss your treatment safely with your doctor.

1. Antacids and Acid-Reducing Medicines

Interaction: Medicines such as omeprazole, pantoprazole, and famotidine can reduce the absorption of dasatinib, potentially affecting how well it works.

Advice: Tell your doctor if you regularly take medicines for acidity or heartburn. Do not change the timing or stop these medicines without medical guidance.

2. Antibiotics and Antifungal Medicines

Interaction: Certain medicines, including clarithromycin, ketoconazole, and itraconazole, may increase dasatinib levels in the body. Some antibiotics, such as rifampicin, may lower its levels and reduce its effect.

Advice: Always check with your doctor before starting an antibiotic or antifungal medicine during treatment.

3. Blood Thinners and Medicines That Increase Bleeding Risk

Interaction: Medicines such as warfarin and some other blood thinners may increase the risk of bleeding when taken with dasatinib.

Advice: Inform your doctor about any blood-thinning medicines you use. Report unusual bruising, prolonged bleeding, or blood in your urine or stools promptly.

4. Other Medicines That Affect Heart Rhythm

Interaction: Some medicines can affect the heart's electrical rhythm. Combining them with dasatinib may increase the risk of heart rhythm problems in susceptible individuals.

Advice: Tell your doctor about all heart medicines and any history of heart rhythm problems before starting treatment.

5. Grapefruit and Grapefruit Juice

Interaction: Grapefruit may interfere with the enzyme responsible for breaking down dasatinib, potentially increasing its levels in the body.

Advice: Avoid grapefruit and grapefruit juice during treatment unless your healthcare professional advises otherwise.

6. Herbal Products and Supplements

Interaction: Certain herbal products, particularly St. John's wort, may lower dasatinib levels and affect treatment effectiveness.
