Sunitinib
Administration
This oral medication (pill) is typically taken once daily, with or without food, following either a cyclic regimen (4 weeks on treatment, 2 weeks off treatment) or a continuous regimen, which depends on the specific diagnosis. Alternative schedules, such as 2 weeks on and 1 week off, may also be used to enhance tolerability.Potential Side Effects & Management
• Infection Risk: Given treatments’ intensity, reduced white blood cell counts heighten infection risks, necessitating vigilance and timely medical intervention. If you have a fever over 38.3°C, you should advise your medical team or go to the emergency department.
• Anemia: Reduced red blood cells due to treatment can cause anemia. If severe, blood transfusion might be necessary.
• Bruising and Bleeding: Reduced platelets due to treatment can lead to easy bruising, nosebleeds, or blood in urine/stool. Platelet transfusion might be necessary.
• Nausea, Vomiting and Hair Changes: Managing these side effects can significantly impact quality of life during treatment.
• Stomach Pain: Pain, bloating, indigestion, or discomfort in the abdomen. Your doctor can prescribe medications to alleviate these symptoms.
• Diarrhea: Increased bowel activity.
• Sore Mouth & Throat: Treatment may cause sore mouth and throat which can potentially lead to mouth ulcers and increased risk of infection. Maintain oral hygiene; contact your healthcare team for mouthwash or medicines if needed.
• Fatigue: This treatment may cause fatigue or weakness, which can impact daily activities.
• Liver Problems: This treatment can lead to liver injury, characterized by elevated levels of liver enzymes (transaminases) in the blood. Close monitoring of liver function through regular blood tests is essential.
• Rash: Rash symptoms typically start within 2 to 4 weeks of treatment initiation but may also appear later, even after a few months.
• Abnormalities in laboratory tests: Electrolyte (essential minerals in the blood) imbalances, issues with pancreatic function (abnormal amylase and lipase), and renal dysfunction, may occur as side effects of this treatment.
• Hypertension: This treatment may cause elevated blood pressure.
• Hand-Foot Syndrome: Hand-foot skin reaction characterized by redness, swelling, pain, and sometimes blistering on the palms of the hands and soles of the feet.
When to Seek Medical Attention
If you experience the following symptoms, seek immediate medical attention to assess and manage potential complications:
1. Painful Skin Ulcers:
– Painful skin ulcers are open sores on the skin that cause discomfort and may be accompanied by redness, swelling, or drainage.
– Monitor for signs of infection such as increased pain, warmth, or pus discharge from the ulcer.
2. Blood Clots:
– Blood clots are gel-like clumps of blood that can form inside blood vessels, potentially leading to serious complications such as heart attacks or strokes.
– Watch for symptoms like numbness or weakness on one side of the body, sudden severe headache, or trouble speaking, which could also signal a blood clot.
3. Hemorrhage:
– Hemorrhage refers to severe bleeding, either internally or externally, which can lead to life-threatening complications.
– Look out for excessive bruising, nosebleeds, or bleeding gums, which could indicate internal bleeding.
4. Posterior Reversible Encephalopathy Syndrome (PRES):
– Posterior Reversible Encephalopathy Syndrome (PRES) is a rare neurological disorder characterized by symptoms such as headache, confusion, or visual disturbances, often accompanied by high blood pressure.
– Be vigilant for seizures, lethargy, or other neurological changes, which may indicate the onset of PRES.
5. Life-threatening Soft-tissue Infections:
– Life-threatening soft-tissue infections involve severe infection around skin injuries, leading to systemic complications if left untreated.
– Look out for symptoms such as high fever, severe pain, or rapid worsening of the infection, which may require urgent medical attention.
6. Heart Rhythm Problems:
– Heart rhythm problems refer to abnormalities in the heart’s electrical activity, which can lead to serious complications such as cardiac arrest.
– Watch for irregular heartbeats, fluttering sensations in the chest, or episodes of palpitations, which may indicate underlying heart rhythm disturbances.
7. Severe Skin Rash:
– Severe skin rash involves the development of extensive skin lesions, often accompanied by blistering or peeling.
– Look out for signs of allergic reaction such as swelling of the face, lips, or tongue, or difficulty breathing, which may indicate a severe skin rash.
8. Infection:
– Infection refers to the invasion and multiplication of harmful microorganisms in the body, leading to inflammatory responses and tissue damage.
– Monitor for symptoms like sore throat, cough, or difficulty breathing, which may indicate respiratory infection or systemic illness.
9. Myopathy or Rhabdomyolysis:
– Myopathy or rhabdomyolysis involves muscle-related symptoms such as muscle aches, weakness, or dark urine due to muscle breakdown.
– Look out for muscle stiffness, cramping, or difficulty moving, which may indicate muscle damage requiring medical evaluation.
10. Osteonecrosis in the Jaw:
– Osteonecrosis in the jaw refers to bone death in the jawbone, leading to symptoms such as jaw pain, swelling, or exposed bone.
– Watch for symptoms such as loosening of teeth, difficulty chewing, or persistent mouth sores, which may indicate jaw osteonecrosis requiring dental evaluation.
