Polytar 1.0 %
Before using Polytar 1.0% (a topical treatment), it is essential for patients to consult their healthcare provider due to potential risks and considerations. Important precautions include:
- Skin Sensitivity: Polytar contains coal tar, which may cause skin irritation or allergic reactions, particularly in sensitive individuals. It is recommended to perform a patch test before widespread use.
- Sun Exposure: Coal tar can make the skin more sensitive to sunlight, increasing the risk of sunburn. Patients should avoid prolonged sun exposure and use protective clothing or sunscreen.
- Pregnancy and Lactation: The safety of coal tar products during pregnancy and breastfeeding is not well established. Polytar should be used during pregnancy only if clearly needed, and mothers should discuss the potential risks with their healthcare provider before using it during lactation.
- Pre-existing Skin Conditions: Patients with open wounds, cuts, or severe skin infections should avoid using Polytar on those areas, as the product may exacerbate irritation or interfere with healing.
- Eye Contact: Polytar should not be applied near the eyes. It is crucial to avoid accidental contact with the eyes, as coal tar can cause significant irritation and discomfort.
- Use in Children: Use Polytar with caution in children, as their skin is more sensitive and prone to irritation. A healthcare provider should assess whether the benefits outweigh the risks for pediatric use.
Polytar 1.0% is primarily indicated for the treatment of various scalp and skin conditions. Its key therapeutic uses include:
- Psoriasis: Polytar is often used to treat psoriasis by reducing scaling, itching, and inflammation associated with this chronic skin condition.
- Seborrheic Dermatitis: The product is effective in treating seborrheic dermatitis, a condition characterized by red, flaky skin, particularly on the scalp, face, and chest.
- Dandruff: Polytar is frequently used to manage dandruff, helping to reduce flaking and itching of the scalp.
- Eczema: Polytar can be used to treat eczema by alleviating symptoms such as dryness, irritation, and inflammation on the skin.
- Other Chronic Skin Conditions: Coal tar-based products like Polytar are sometimes used for other dermatologic conditions, such as lichen planus or pruritus (itchy skin), to soothe and control symptoms.
There are certain situations where Polytar 1.0% should not be used. These contraindications include:
- Hypersensitivity to Coal Tar: Polytar is contraindicated in patients with a known allergy or hypersensitivity to coal tar or any of its components, as this can lead to skin reactions or other severe allergic symptoms.
- Acute Skin Conditions: Polytar should not be applied to acute inflammatory skin diseases, such as open wounds, cuts, or severely infected skin, as it can exacerbate irritation or delay healing.
- Photosensitivity: Patients with a history of photosensitivity (sensitivity to light) or those who are undergoing phototherapy should avoid using Polytar, as it can increase the skin's sensitivity to sunlight, leading to an increased risk of sunburn or other skin damage.
- Severe Liver Impairment: While coal tar is generally applied topically, excessive use or systemic absorption could potentially affect the liver. Therefore, caution is advised in patients with severe liver disease.
Like any topical medication, Polytar 1.0% may cause side effects. Common and severe side effects include:
Common Side Effects:
- Skin Irritation: Localized irritation, itching, or burning at the application site is a common side effect. This typically resolves once treatment is discontinued or adjusted.
- Dryness or Flaking: Polytar may cause the skin to become dry or flaky, which is part of its therapeutic action for conditions like psoriasis. Patients may need to use a moisturizer to alleviate dryness.
- Staining: Coal tar products like Polytar can stain clothes, bedding, and towels. It is recommended to wear old clothing during use to avoid staining.
Severe Side Effects:
- Severe Allergic Reactions: In rare cases, Polytar can cause severe allergic reactions, including swelling, redness, blistering, or hives. If any of these symptoms occur, the medication should be discontinued, and medical help should be sought immediately.
- Photosensitivity: Prolonged use of Polytar can increase sensitivity to sunlight, making the skin more prone to sunburn or other light-induced damage. Patients should take steps to protect their skin from sun exposure during treatment.
- Skin Hyperpigmentation: Although rare, the use of coal tar can cause darkening of the skin in certain individuals, especially with prolonged or heavy use.
- Contact Dermatitis: In some cases, prolonged use can lead to contact dermatitis, a condition characterized by skin redness, swelling, and itching.

Polytar 1.0% works as a keratolytic agent, primarily due to the presence of coal tar. Its mechanism of action includes:
- Slowing Cell Growth: Coal tar helps to slow the rapid skin cell turnover that occurs in conditions like psoriasis, thereby reducing the formation of thick, scaly patches on the skin.
- Anti-inflammatory Effects: It has mild anti-inflammatory properties that help reduce redness, swelling, and irritation associated with inflammatory skin conditions.
- Antipruritic Effect: Coal tar can also alleviate itching (pruritus) by soothing the skin and reducing the urge to scratch, which can worsen skin conditions.
- Antiseptic Properties: Coal tar has mild antiseptic properties that help to prevent secondary bacterial infections on irritated or compromised skin.
Polytar 1.0% is a topical product with limited systemic absorption, meaning the risk of significant drug interactions is minimal. However, interactions may still occur in specific circumstances:
- Other Topical Treatments: When used in combination with other topical treatments or creams, particularly those containing alcohol or peroxide, Polytar may cause excessive dryness or irritation of the skin. It's important to use such products with caution and follow the recommended instructions.
- Photosensitizing Agents: Since Polytar can increase the skin's sensitivity to sunlight, using it alongside other photosensitizing agents (such as certain antibiotics or diuretics) may heighten the risk of sunburn or skin damage.
- Skin Irritants: Concurrent use of Polytar with products that irritate the skin, such as harsh cleansers or exfoliants, should be avoided as it can intensify irritation.
For adult use, Polytar 1.0% is typically applied topically to the affected area, with specific dosing depending on the condition being treated. General guidelines include:
- Psoriasis and Dermatitis: Apply a thin layer of Polytar 1.0% to the affected area of the skin once or twice daily. Gently massage it in to ensure even coverage. The treatment duration may vary depending on the condition and the response to therapy, but it is typically continued for several weeks.
- Dandruff and Seborrheic Dermatitis: When used on the scalp, Polytar 1.0% is typically applied once daily or as directed by the healthcare provider. It is often recommended to leave the product on for a period of time (such as 10–15 minutes) before rinsing.
Polytar 1.0% should be used with caution in pediatric patients, especially in those under the age of 2, due to the increased risk of skin irritation. The general dosing recommendations for children include:
- Psoriasis: In children, apply a thin layer of Polytar to the affected area once or twice daily. The duration of use should be determined by a healthcare provider.
- Dandruff or Seborrheic Dermatitis: For children, a gentle application to the scalp is recommended, but it should be used sparingly to avoid excess irritation.
As always, it is important for parents or guardians to consult with a healthcare provider before using Polytar 1.0% in children to ensure it is appropriate for the child’s condition.
To summarize, patients should consult their healthcare provider before starting Polytar 1.0% to ensure it is the right treatment for their condition and to prevent any potential complications.
Since Polytar is used topically and has minimal systemic absorption, dose adjustments are generally not required for individuals with renal impairment. However, patients with significant kidney issues should use the product cautiously and under the supervision of a healthcare provider to avoid potential complications.
