Ringworm is a common infection which is very contagious and can affect the scalp, body, feet, face, or nails.
About 20 percent of people will have this infection at some stage of their lives.
It is caused by fungi which normally live on the hair, skin, and nails called dermatophytes.
Common symptoms of ringworm include:
- sharply defined edges, occasionally darker around the edge;
- scaly, crusted rash;
- raised, red patches which can blister or ooze;
- an itchy and unpleasant sensation on your skin.
Note – you might not know you have ringworm until the rashes appear since it has an incubation period of up to 2 weeks.
It is a common, itchy rash of the groin that is associated with a pink or red rash involving the genitals and groin folds.
The rash is also caused by dermatophytes.
Symptoms of jock itch include:
- flaking, cracking, or peeling skin;
- a red, scaly, circular rash with raised edges;
- burning and itching.
Both infections can be treated effectively with most antifungal medications.
Here is a comparison between Tinactin and Lotrimin, two topical antifungals:
It is an antifungal medication which fights infections caused by fungus and whose main ingredient is tolnaftate. It is used to treat:
- infections of the scalp, palms, nails, and soles of the feet;
- ringworm (tinea corporis);
- jock itch (tinea cruris);
- athlete’s foot (tinea pedis).
Its main ingredient is clotrimazole, a medication that belongs to a group of drugs called antifungals.
It is commonly used for the treatment of:
- oral thrush;
- athlete’s foot (tinea pedis);
- ringworm (tinea corporis);
- jock itch (tinea cruris).
Mechanism of Action
Tinactin works by suppressing a vital fungal enzyme that is responsible for maintaining the integrity of the fungal cell’s membrane.
Lotrimin works by inhibiting the growth of infection-causing yeast.
Possible side effects of Tinactin include:
- stinging at the application site;
- irritation at the application site;
- severe itching, peeling, dryness, redness, or blistering (in very rare cases).
Possible side effects of Lotrimin include:
- itching, swelling, redness, irritation, burning at the site of application;
- swelling of the skin.
The cream must be applied to the affected skin area two times per day (in the morning and at night).
Notes – do not use coverings (dressings, bandages, make-up) unless told to do so by your healthcare provider.
Before application of the antifungal cream, the affected skin area must be washed and dried.

Tinactin vs Lotrimin – Differences
Tinactin (tolnaftate) stops the growth of fungi which cause skin infections, such as – jock itch, athlete’s foot, and ringworm.
Lotrimin (clotrimazole) is an antifungal medication that works by disrupting the cell membrane and is part of the azole class of medications.
