2. Wash your hands thoroughly with soap and water before and after applying the treatment. If you are treating an infection on your hands, wash them before application only.
3. Keep the medicine away from your eyes. If it accidentally gets into your eyes, rinse them right away with plenty of clean water for several minutes.

Using It on Young Children
Doctors sometimes prescribe this medicine for children older than two years. However, you must only use it on children under strict medical guidance. Always consult your pediatrician before applying any medicated cream or solution to a child's skin.
What If You Use Too Much?
If you think you applied too much medicine by mistake, or if someone swallows it accidentally, take immediate action. In the US or Canada, call poison control or 911. In the UK, call 999 or NHS 111. You can also go straight to your nearest hospital emergency department (ER or A&E).
Remember: This medicine is prescribed just for you. Even if someone else has the exact same symptoms, never share your medicine with them.
Things to Watch Out For While Using the Medicine
Stopping fungal infections from coming back requires more than just applying cream. Pay attention to daily habits while you treat your skin.
- If your symptoms do not improve, or if they get worse, contact your doctor right away. Talk to your doctor if you need to use the medicine for longer than four weeks.
- Keep your skin dry. Fungi love moisture, so dry your body completely after bathing or swimming.
- Wear clean, freshly washed cotton clothes. Synthetic fabrics trap sweat and create a warm environment where fungi grow easily.
These habits matter most when treating conditions like athlete's foot between your toes or jock itch in your groin area.
