Drug Description


Grisovin is indicated to treat skin, hair, and nail infections caused by certain types of fungi unresponsive to topical treatments like creams or lotions. 

As an antifungal medication, Grisovin works by halting the growth of fungi causing infection. 

Uses and Dosage 

Before taking Grisovin and with each prescription refill, thoroughly review the accompanying medication guide and patient information leaflet. Consult your healthcare provider or pharmacist for any queries or concerns. 

The prescribed dosage of Grisovin may differ for each patient, depending on their medical condition, treatment response, and age in the case of children. 

This medication is typically taken as a single or divided dose daily, preferably with or after a moderately fatty meal. Discuss specific dietary guidance with your doctor, especially if you follow a low-fat diet. 

For best results, take Grisovin at evenly spaced intervals, as antifungal medications are most effective when the medicine remains at a steady level in the body. 

The duration of treatment with this medication may vary according to the type of infection. Treating scalp, feet, and body infections may take weeks to months, while nail infections might require several months to a year or more. 

Adhere to your doctor’s instructions precisely when taking this medication. Complete the full prescribed treatment duration, even if symptoms improve early, as stopping too soon could allow the fungus to persist, potentially leading to a recurrence of the infection. 

Take Grisovin solely for the prescribed condition as it is ineffective against certain fungal infections, including yeast infections and bacterial or viral conditions like the flu or common cold.
