Itching under the thighs near the penis is often caused by a fungal infection like jock itch, which is common in that area. Using an antifungal cream such as Lulifin Cream, which contains luliconazole, can help clear the infection by killing the fungus causing the irritation.

• Apply a thin layer of Lulifin Cream to the clean, dry affected area once or twice daily as directed.
• Avoid contact of the cream with eyes, mouth, or other sensitive areas; rinse thoroughly if accidental contact occurs.
• Keep the area dry and wear loose, breathable clothing to reduce moisture buildup.
• If redness, swelling, or irritation worsens or persists beyond a week, consult a dermatologist for further evaluation.
• If you have allergies, are pregnant, or breastfeeding, check with a doctor before use.
