This medication comes in different topical forms, including a spray, powder spray, cream, and liquid. Tolnaftate can be used for adults and children 2 years and older, unless otherwise directed by a provider. Most people have few to no side effects while using this medication, though some can have mild skin irritation.

Prevention of athlete’s foot
Tolnaftate is an antifungal medication. It works by blocking a protein that fungi need so they can grow. This stops the fungi from spreading and kills them to treat the infection.

Always read the package label of the tolnaftate topical product you have to check that it can be used for the type of fungal infection you have and for instructions. Different formulations of tolnaftate topical products are used for fungal infections on different parts of the body and have different instructions. Only certain topical products are used for jock itch (e.g., powder spray, Tinactin cream).
Before applying tolnaftate, wash your hands and clean the affected area(s) of your skin.
Use tolnaftate only on the outside of your body (e.g., skin). Don't swallow this medication, and never use it in your eyes, nose, or ears.
If you're using tolnaftate for athlete’s foot, remember to apply it in between the toes as well. Wear shoes that fit well and are breathable. Change your shoes and socks daily. This will help your infection clear up as quickly as possible and will also help prevent the infection from spreading.
Wash your hands after using tolnaftate to help prevent getting the medication in your eyes. Rinse your eyes with water or saline if you accidentally get it in your eyes. Contact your provider if the irritation doesn't go away.
Stop using tolnaftate and talk with your provider if you don't see any improvement after using for more than a month (for athlete's foot and ringworm) or for more than 2 weeks (for jock itch). Your provider might suggest a different medication for you.
Store tolnaftate up and away and out of children's reach and sight when you're not using it. This prevents them from accidentally swallowing medication that was left out. Call your Poison Control Center at 1-800-222-1222 if you think that your child might’ve accidentally swallowed tolnaftate, even if you aren't completely sure.
For tolnaftate topical liquid: Use the brush applicator to apply the medication on the skin around the nails. Don't apply tolnaftate on the scalp or on your nails since this medication doesn't work well for fungal infections in these areas.
For tolnaftate topical sprays (liquid and powder): Shake the can well before using so it's evenly mixed. Be careful not to breathe in the medication while using. Avoid using the topical spray near any open flames or while smoking because it can catch on fire easily. Also, keep the can or bottle away from heat, and don't puncture it. Otherwise, the can or bottle might explode because it's under a lot of pressure.
Tolnaftate can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Tolnaftate should only be used on your skin. Don’t put it in your eyes, nose, mouth, or ears. Avoid inhaling tolnaftate topical spray during treatment. Call your Poison Control Center at 1-800-222-1222 right away if you think that your child might’ve accidentally swallowed or inhaled this medication.
Don't use tolnaftate topical sprays (liquid and powder) near an open flame or while smoking. These formulations of the medication can catch on fire very easily. Also, don't store them near heat or puncture the bottle. The bottle is under a lot of pressure and might explode in these conditions.
