Learn about Nizoral Cream (Ketoconazole) for fungal skin infections in Singapore. This article covers its uses for conditions like athlete's foot, ringworm, and seborrheic dermatitis, where to buy it, how to use it, potential side effects, precautions, and comparisons to other antifungal treatments. Understand how Ketoconazole works and find effective relief.
What is Nizoral Cream
Nizoral Cream is a topical antifungal medication used to treat a variety of fungal skin infections. Its active ingredient, ketoconazole, effectively combats the growth of fungi, providing relief from itching, redness, and scaling associated with these infections.
Understanding Ketoconazole
Ketoconazole is a broad-spectrum synthetic antifungal agent that belongs to the imidazole class. It works by disrupting the cell membranes of fungi, inhibiting their growth and ultimately eliminating the infection. This makes it effective against a wide range of fungal species.
How Ketoconazole Works
Ketoconazole specifically targets the production of ergosterol, a crucial component of fungal cell membranes. By inhibiting the synthesis of ergosterol, ketoconazole weakens the cell membrane, causing it to become permeable and leaky. This disruption leads to the leakage of essential cellular components, ultimately resulting in the death of the fungal cells.
Benefits of Ketoconazole Cream
Ketoconazole cream offers several advantages in treating fungal skin infections:
Broad-spectrum activity: Effective against a wide range of fungal species.
Topical application: Targets the affected area directly, minimizing systemic side effects.
Relief from symptoms: Reduces itching, burning, redness, and scaling.
Available over-the-counter in some countries: Convenient access for mild to moderate infections.

Common Fungal Skin Infections Treated by Nizoral Cream
Athlete's Foot (Tinea Pedis)
Athlete's foot, also known as tinea pedis, is a common fungal infection that affects the feet. Symptoms often include itching, burning, stinging, and redness between the toes. The skin may also appear scaly, cracked, or blistered. In severe cases, the infection can spread to the toenails, causing them to thicken, discolor, and even crumble.
Treatment with Nizoral Cream
Nizoral cream, with its active ingredient ketoconazole, is effective in treating athlete's foot by inhibiting the growth of the fungus. Regular application as directed can alleviate symptoms and clear the infection.
Less Common Symptoms
Less common symptoms can include dry, flaky skin on the soles or sides of the feet, and small, fluid-filled blisters.
Causes of Athlete's Foot
Athlete's foot thrives in warm, moist environments, making places like public showers, locker rooms, and swimming pools common breeding grounds for the fungus. Sharing towels, socks, or shoes with an infected person can also spread the infection.
Jock Itch (Tinea Cruris)
Jock itch, or tinea cruris, is a fungal infection that affects the groin, inner thighs, and buttocks. It's characterized by an itchy, red rash that can be ring-shaped. The skin may also appear scaly or cracked.
Less Common Symptoms
Sometimes, jock itch can present with small, raised bumps or pustules.
Treatment with Nizoral Cream
Nizoral cream can effectively treat jock itch by targeting the fungus and relieving the associated symptoms. Consistent application is crucial for successful treatment.
Causes of Jock Itch
The fungus that causes jock itch thrives in warm, moist areas. Tight-fitting clothing, excessive sweating, and obesity can increase the risk of developing this infection. It can also be spread through direct contact with an infected person or contaminated clothing.
Ringworm (Tinea Corporis)
Ringworm, or tinea corporis, is a fungal infection that can appear anywhere on the body. It's characterized by a circular or ring-shaped rash with a raised, scaly border. The center of the ring may be clear or slightly red.
Less Common Symptoms
In some cases, multiple rings may appear and overlap, creating a larger, more complex rash. The rash can also be itchy and uncomfortable.
Treatment with Nizoral Cream
Nizoral cream is an effective treatment for ringworm, helping to eliminate the fungus and clear the rash. It's important to apply the cream to the entire affected area and a small margin around it.
Causes of Ringworm
Ringworm is highly contagious and can be spread through direct contact with an infected person or animal, or by touching contaminated objects like clothing, towels, or bedding. It can also be spread by contact with infected soil.
Seborrheic Dermatitis
Seborrheic dermatitis is a chronic skin condition that causes flaky, white or yellowish scales to develop on oily areas of the body, such as the scalp, face, chest, and back. The affected skin may also be red and itchy.
Less Common Symptoms
In infants, seborrheic dermatitis can present as cradle cap, a thick, greasy, yellowish scaling on the scalp.
Treatment with Nizoral Cream
Nizoral cream can help manage seborrheic dermatitis by controlling the yeast overgrowth and reducing inflammation. It's often used on the face and body, while Nizoral shampoo is typically used for the scalp.
Causes of Seborrheic Dermatitis
The exact cause of seborrheic dermatitis is unknown, but it's thought to be related to an overgrowth of a yeast called Malassezia and an inflammatory response from the body. Factors like stress, hormonal changes, and certain medical conditions can exacerbate the condition.
Pityriasis Versicolor
Pityriasis versicolor is a fungal infection that causes small, discolored patches of skin. These patches can be lighter or darker than the surrounding skin and are often found on the chest, back, and shoulders. They may be slightly scaly and can become more noticeable after sun exposure.
Less Common Symptoms
The patches can sometimes be itchy or slightly raised.
Causes of Pityriasis Versicolor
Pityriasis versicolor is caused by an overgrowth of yeast that normally lives on the skin. Factors like warm, humid weather, oily skin, and a weakened immune system can contribute to the overgrowth.
Treatment with Nizoral Cream
Nizoral cream can effectively treat pityriasis versicolor by eliminating the overgrowth of yeast. Regular application is essential for clearing the infection and restoring normal skin pigmentation. It's important to note that the discoloration may take several months to fully disappear even after the infection is treated.
