How should I use Loprox?

Use exactly as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.

Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.

Wash your hands before and after using this medication, unless you are using ciclopirox to treat a hand condition.

To apply the cream, gel, or lotion:

  • Clean and dry the affected area. Apply a small amount of the cream (usually twice daily) for 2 to 4 weeks. Follow your doctor's instructions.
  • Do not use bandages or dressings that do not allow air to circulate (occlusive dressings) on areas treated with ciclopirox cream or lotion, unless otherwise directed by your doctor. Wear loose-fitting clothing (preferably cotton).
  • If the infection does not clear up in 4 weeks, or if it appears to get worse, see your doctor.

To use ciclopirox shampoo:

  • Wet the hair and apply approximately 1 teaspoon (5 mL) of the shampoo to the scalp. Up to 2 teaspoons (10 mL) may be used for long hair. Lather and leave on the hair and scalp for 3 minutes. A timer may be used.
  • Treatment should be repeated twice per week for 4 weeks, with a minimum of 3 days between applications. If no improvement is seen after 4 weeks of treatment, contact your doctor.

It may take up to 4 weeks before your symptoms improve after using Loprox cream, gel, lotion, or shampoo. Keep using the medicine as directed and tell your doctor if your symptoms do not improve, or if they get worse.

To use ciclopirox nail lacquer:

  • Use on the nails and immediately surrounding skin only. Avoid contact with other areas. Remove any loose nail or nail material using nail clippers or a nail file.
  • Apply ciclopirox nail lacquer once daily (preferably at bedtime) to all affected nails with the applicator brush provided. Apply the lacquer evenly over the entire nail. Where possible, apply the nail lacquer to the underside of the nail and to the skin beneath it. Allow the lacquer to dry (approximately 30 seconds) before putting on socks or stockings. After applying the medication, wait 8 hours before taking a bath or shower.
  • Apply ciclopirox nail lacquer daily over the previous coat. Once a week, remove the nail lacquer with alcohol. Remove as much as possible of the damaged nail using nail clippers or nail a file.
  • To prevent the screw cap from sticking to the bottle, do not allow the solution to get into the bottle treads. To prevent the solution from drying out, close the bottle tightly after every use.

Treatment with ciclopirox nail lacquer may require several months before initial improvement of symptoms is noticed. Up to 48 weeks of daily application of the nail lacquer, monthly removal of the unattached infected nail by a health care professional, and weekly trimming by the patient may be required for complete treatment.

Use this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antifungal medicine.

Store all forms of this medicine at room temperature away from moisture, heat, and light. Once a bottle of ciclopirox shampoo is opened, it should be used within 8 weeks.

Ciclopirox nail lacquer is flammable. Avoid using near open flame, and do not smoke until the gel has completely dried on your skin.

What happens if I miss a dose?

Use the missed dose as soon as you remember. If it is almost time for your next scheduled dose, skip the missed dose. Do not use extra medicine to make up for the missed dose.

Common questions about Loprox

What home remedies work well for toenail fungus?
Toenail fungus can be challenging to treat, especially when severe. Trim and debride nails before treatment for better results. Maintain foot hygiene by washing, drying, and wearing appropriate footwear. Keep nails short and treat athlete's foot if present. Home remedies can improve affected nails but may not fully eliminate the problem, especially for severe cases. Consulting a doctor is advisable, as oral medications may be necessary for severe infections. For minor cases, home remedies such as apple cider vinegar, tea tree oil (Malaleuca alternifolia), oregano oil, Listerine, baking Soda and epsom Salts, garlic, or coconut oil, may help.
