Clioquinol is used to treat skin infections such as eczema, athlete's foot, jock itch, and ringworm.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
Clioquinol comes as a cream, lotion, and ointment to apply to the skin. Clioquinol is usually used two to four times a day for 4 weeks (2 weeks for jock itch). Follow the directions on the label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use clioquinol exactly as directed. Do not use more or less of it or use it more often than indicated on the product label.
Thoroughly clean the infected area, allow it to dry, and then gently rub the medication in until most of it disappears. Use just enough medication to cover the affected area. You should wash your hands after applying the medication.
Before using clioquinol,
- tell your doctor and pharmacist if you are allergic to clioquinol or any other drugs.
- tell your doctor and pharmacist what prescription and nonprescription drugs you are taking, including vitamins.
- tell your doctor and pharmacist if you are about to take a thyroid function test.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while using clioquinol, call your doctor.
Apply the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not apply a double dose to make up for a missed one.
Clioquinol may cause side effects. If you experience any of the following symptoms, call your doctor immediately:
- irritation or stinging
If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online [at Web Site] or by phone [1-800-332-1088].
