Drug Description


Lamisil Spray is a prescribed topical medication that effectively treats athlete’s foot (tinea pedis) between the toes, jock itch (tinea cruris), and ringworm (tinea corporis).  

As an antifungal medication, Lamisil Spray works by inhibiting the growth of fungus. It also provides relief from itching, burning, cracking, and scaling associated with the said conditions. 

Uses and Dosage 

Before using Lamisil Spray and with each prescription refill, thoroughly review its medication guide and patient information leaflet. Consult your doctor or pharmacist if you have any inquiries or concerns. 

Lamisil Spray is intended for external use only. It should not be applied to nails or the scalp, near the mouth or eyes, or used for treating vaginal yeast infections. 

The dosage and duration of treatment with Lamisil Spray may vary based on the specific infection being treated. 

The usual recommended dosage is as follows; however, in case of a different prescription, strict adherence is advised: 

  • For athlete’s foot between toes: apply the spray to the affected twice daily (morning and night) for one week, or as instructed by your doctor. Wear properly fitted, breathable footwear and change shoes and socks at least once per day 
  • For jock itch and ringworm: apply the spray to the affected area once daily (morning or night) for 1 week or as directed by the doctor. 

To ensure the correct usage of this spray, follow these steps: 

  1. Wash your hands before application. 
  2. Wash the affected area with soap and water, thoroughly drying it before application. 
  3. Remove the clear cap to open the spray. 
  4. Hold the can approximately 4″ to 6″ away from the skin, then press and hold to spray a thin layer over the affected area. (Avoid contact with the eyes. In case of accidental contact, promptly rinse the eyes with water) 
  5. Release the spray button to stop spraying. 
  6. After each use, wipe off any excess from the spray opening. 
  7. Wash your hands after each use unless the treated area is on the hands. 

Refrain from wrapping, covering, or bandaging the treated area unless specifically instructed by your doctor. 

For optimal results, use Lamisil Spray consistently at regular times daily. Do not exceed the recommended frequency or duration of use, as doing so may heighten the risk of side effects. 

Adhere to the prescribed treatment period and continue using Lamisil Spray as directed, even if symptoms improve within a few days. Discontinuing this medication prematurely may lead to a recurrence of the infection. 

Inform your doctor if your condition worsens or does not show improvement after one week of treatment.
