Tazorac

Plaque Psoriasis

Tazorac is indicated for the topical treatment of patients with plaque psoriasis. It is typically used for stable plaque psoriasis that covers up to 20% of the body surface area. The medication helps to reduce the thickness, redness, and scaling of psoriasis patches by slowing the overgrowth of skin cells.

Acne Vulgaris

This medication is also used to treat mild-to-moderate facial acne. It helps clear existing acne lesions and may prevent new ones from forming by keeping pores from becoming clogged and reducing the formation of blackheads and whiteheads.

Formulations

Tazorac is available in different forms depending on the condition being treated and the patient's skin type:

• Cream: Commonly prescribed for both plaque psoriasis and facial acne.
• Gel: Also used for the treatment of both plaque psoriasis and facial acne.

Healthcare providers select the specific strength and formulation based on the severity of the condition and how the skin responds to the treatment.

Mechanism of Action

Tazorac contains tazarotene, a compound derived from vitamin A known as a retinoid. While the exact way it works to treat skin conditions is not fully understood, it is known to affect the expression of certain genes that control skin cell growth and inflammation.

How it Affects the Skin

Once applied to the skin, tazarotene is converted into its active form, tazarotenic acid. It then binds to specific retinoic acid receptors within the skin cells. This process helps to manage skin conditions in several ways:

• Regulating cell growth: In conditions like plaque psoriasis, where skin cells multiply much faster than normal, the medication helps slow down this overproduction and normalizes how cells mature.
• Clearing pores: In acne treatment, it helps regulate the shedding of skin cells that line the pores. This prevents the pores from becoming blocked with oil and debris, which helps prevent blackheads, whiteheads, and pimples from forming.
• Reducing inflammation: It helps decrease the redness and swelling associated with both acne breakouts and psoriasis plaques.

Common Side Effects

• Skin peeling or flaking
• Redness or itching
• Burning, stinging, or tingling sensations
• Dry skin
• Skin pain or irritation
• Swelling at the application site
• Worsening of psoriasis symptoms

These symptoms are generally mild to moderate and often decrease as the skin becomes accustomed to the medication. Using a moisturizer as directed by a healthcare provider may help manage dryness and peeling.

Serious Side Effects

Seek medical attention immediately if you experience any of the following:

• Severe skin redness, swelling, or blistering
• Intense skin pain or burning
• Signs of an allergic reaction, including hives, rash, or swelling of the face, lips, or throat
• Difficulty breathing
• Extreme sensitivity to sunlight or wind

Pregnancy and Birth Defects

Tazorac must not be used by individuals who are pregnant or planning to become pregnant. This medication can cause serious birth defects if used during pregnancy. A negative pregnancy test is typically required within two weeks before starting treatment, and effective birth control must be used throughout the duration of therapy.

Sun Sensitivity

This medication increases sensitivity to ultraviolet (UV) light. Exposure to sunlight, sunlamps, or tanning beds may result in severe sunburn or skin irritation. It is important to:

• Apply sunscreen with an appropriate SPF daily.
• Wear protective clothing, such as hats and long sleeves, when outdoors.
• Avoid use on skin that is already sunburned.

Local Skin Reactions

Tazorac may cause significant skin irritation, including redness, peeling, burning, and stinging. These effects are more likely to occur during the first few weeks of treatment. Caution is advised when:

• Applying the medication to skin affected by eczema, as it may cause severe irritation.
• Using other topical products that have a strong drying effect, such as those containing alcohol, astringents, or spices.
• Exposing treated skin to extreme weather conditions, such as strong wind or cold temperatures.

Application Precautions

The medication should only be applied to the affected areas. Contact with the eyes, mouth, and other mucous membranes should be avoided. If the medication enters the eyes, they should be rinsed thoroughly with water.

Pregnancy

Tazorac is contraindicated for use during pregnancy. As a retinoid, tazarotene has the potential to cause fetal harm and birth defects. Healthcare providers typically require a negative pregnancy test within two weeks before starting treatment to ensure the patient is not pregnant.

Effective birth control should be used throughout the duration of treatment. If pregnancy occurs while using this medication, it is important to stop use immediately and consult a healthcare professional.

Breastfeeding

It is currently unknown if tazarotene passes into breast milk or how it might affect a nursing child. Because many drugs are excreted in human milk, caution is advised when using this medication while breastfeeding.

If a healthcare provider determines that treatment is necessary, avoid applying the medication to the nipple or areola area to prevent the infant from direct contact with or ingestion of the drug.

Dosage Forms

Tazorac is a topical retinoid available in two primary formulations:

• Cream: A white, opaque cream.
• Gel: A clear or translucent gel.

Available Strengths

Both the cream and gel formulations are provided in the following concentrations:

• 0.05%
• 0.1%

These products are typically packaged in tubes for topical application to the skin.

FDA Approval and Indications

Tazorac (tazarotene) is approved by the U.S. Food and Drug Administration (FDA) for the topical treatment of specific skin conditions. Its approved uses include:

• Plaque Psoriasis: For the treatment of stable plaque psoriasis involving up to 20% of the body surface area.
• Acne Vulgaris: For the treatment of mild to moderate facial acne vulgaris.

Pregnancy and Safety Requirements

Tazorac is contraindicated in women who are or may become pregnant. Because the medication may cause birth defects, the FDA and manufacturer guidelines require the following safety protocols:

• A negative pregnancy test must be confirmed within two weeks before starting treatment.
• Therapy should begin during a normal menstrual period.
• Effective contraception must be used throughout the duration of treatment.

Regulatory Status

Tazorac is a prescription-only medication. While it does not currently require a Risk Evaluation and Mitigation Strategy (REMS) program, it is subject to strict labeling requirements regarding its use in women of childbearing age. There are no current major safety recalls or unique regulatory restrictions beyond its pregnancy contraindication.

Clinical Results and Efficacy

Clinical data indicates that Tazorac is effective for treating both acne vulgaris and plaque psoriasis. For acne, it helps clear pores and reduce lesions, while for psoriasis, it helps normalize skin cell growth and reduce inflammation. Most clinical reviews suggest that visible improvement typically occurs within 1 to 4 weeks of starting treatment.

Common Side Effects and Patient Feedback

Patient experiences with Tazorac often highlight the potency of the medication, which can lead to significant skin reactions. The most frequently reported issues include:

• Skin Irritation: Many users experience stinging, burning, or redness shortly after application.
• Dryness and Peeling: Excessive dryness and skin flaking are common as the medication promotes cell turnover.
• Photosensitivity: Users often report increased susceptibility to sunburn, requiring the daily use of sunscreen.

Usage Considerations

To mitigate negative experiences, medical sources recommend applying the medication to dry skin and using a moisturizer to manage peeling. Because the medication can be highly irritating, it is often started at a lower concentration or applied less frequently until the skin develops a tolerance. If irritation is severe, patients are encouraged to speak with a healthcare professional about adjusting their treatment plan.
