I understand that experiencing occasional dizziness and disorientation, especially in sunlight, can be concerning. Since you are taking rosuvastatin for high cholesterol, it is important to evaluate these symptoms carefully.

Recommended Tests:

• Complete Blood Count (CBC): To check for any underlying infections or anemia.
• Blood Glucose (Random): To rule out blood sugar fluctuations that might cause dizziness.
• Thyroid Function Tests (Free T3, Free T4, TSH): Since thyroid abnormalities can contribute to dizziness and disorientation.
• Liver Function Tests: Rosuvastatin can affect liver enzymes, so monitoring liver health is important.
• Creatine Kinase (CK) Levels: To check for muscle damage, as rosuvastatin may cause muscle-related side effects.
• Electrolyte Panel: To assess for any imbalances that might cause dizziness.
• Hearing and Vestibular Tests: If vertigo or inner ear issues are suspected, these can help diagnose conditions like Meniere’s disease or benign paroxysmal positional vertigo.

Medication Side Effect:
Rosuvastatin may cause dizziness, headache, muscle pain, and rarely more serious muscle or liver issues. Monitoring through tests is important to ensure safety.

Relevant Specialties:

1. Neurology – Specializes in disorders related to dizziness, vertigo, and neurological causes of disorientation.
2. Cardiology – For evaluation of cardiovascular causes of dizziness, especially related to blood flow or carotid artery issues.
3. Endocrinology – To assess thyroid function and metabolic causes contributing to symptoms.

Please consult a neurologist or your primary care doctor to discuss these symptoms and arrange appropriate testing. They can help determine the exact cause and adjust your treatment if needed. If symptoms worsen or you experience additional issues like chest pain, severe headache, or weakness, seek immediate medical attention.
