However, some individuals might experience side effects such as headache, dizziness, or gastrointestinal discomfort, which could indirectly affect how you feel. If you notice unusual tiredness or drowsiness after taking this medication, it is important to inform your doctor.

Key points to remember:

• Drowsiness is not typically caused by itraconazole.
• Watch for other side effects like dizziness or headache.
• Always take the medication as prescribed.
• Consult your doctor if you experience any unexpected symptoms.

If you have concerns about how this medication affects you, discussing them with your doctor or pharmacist can provide personalized advice and reassurance.
