Description
Indications
Coal tar is applied topically to alleviate itching, scaling, and flaking associated with skin conditions like psoriasis or seborrheic dermatitis. This medication is classified under keratoplastics, functioning by promoting the shedding of dead cells from the skin’s surface layer and retarding the growth of skin cells. This action reduces scaling and dryness, while also alleviating itchiness commonly experienced with these skin conditions.
Uses and Dosage
This medication is specifically intended for skin application. To prevent irritation, avoid contact with the eyes, nose, mouth, groin, or rectum. In case of accidental contact with these areas, rinse thoroughly with cool water for 15 minutes and wash hands after application.
Apply a small amount of the medication to the affected area, gently massaging it in. Typically, it is applied 1 to 4 times daily or as directed by your doctor. Allow the medication to air dry before coming into contact with clothing. Refrain from applying to broken or infected skin unless advised by your doctor.
For scalp treatment, adhere to the instructions provided in the package. Coal tar products may also be utilized in baths or as hand/foot soaks. Follow package directions meticulously and rinse off thoroughly, as coal tar products can create slippery surfaces in the shower or bath.
Dosage is determined by your medical condition, the type/brand of product, and your response to treatment. Avoid using excessive amounts, increasing frequency, or prolonging use beyond the directed duration, as this won’t expedite the resolution of your condition but may heighten the risk of side effects.
Consistently use this medication to maximize its benefits. Establish a routine by applying it at the same time(s) each day to aid in remembering.
Inform your doctor if your condition persists or worsens. Seek immediate medical assistance if your skin condition covers a large area or if you suspect a serious medical issue.
