It is important to follow the prescribed dosage and complete the full course of treatment to ensure the infection is completely eradicated.
Side Effects
Common side effects of griseofulvin may include nausea, vomiting, diarrhea, headache, and dizziness. It is important to consult a healthcare provider if any side effects persist or worsen.
Precautions
Before taking griseofulvin, inform your healthcare provider about any allergies, medical conditions, or medications you are currently taking. It is important to avoid alcohol consumption while taking griseofulvin, as it can interact with the medication and lead to adverse effects.
