How to use Dandrex Shampoo
This medication is for use on the skin only. Some brands require shaking before use. Check your product package to see if your brand needs to be shaken. Before using this medication, remove any jewelry to avoid damage to it. Avoid getting this medication into your eyes, inside your nose or mouth, or on any areas of broken/inflamed skin since it may cause irritation. If this occurs, flush the area with plenty of water. Consult your doctor or pharmacist if you have any questions about how to use this medication properly.
For the treatment of dandruff or scalp dermatitis, follow the manufacturer's instructions, or use as directed by your doctor. Wet the scalp and massage the medication onto the wet scalp. Leave it on your scalp for 2-3 minutes and rinse thoroughly. Some brands may require a second application. Check your product package to see if your brand requires a repeat application. Be sure to rinse your hair and scalp well with water after each application, especially on bleached, tinted, or permed hair. This medication is usually used 1 or 2 times per week to treat dandruff or seborrheic dermatitis, or less frequently to maintain control of dandruff.
For the treatment of tinea versicolor, apply selenium sulfide to the affected skin. Lather with a small amount of water. Allow it to remain on your skin for 10 minutes. Rinse your skin thoroughly with water after each use. If the medication touches the genital areas or skin folds, rinse the area well with water for a few minutes to prevent irritation. This medication is applied usually once daily for 7 days to treat tinea versicolor, or use as directed by your doctor.
Wash your hands after using selenium sulfide. Do not leave this medication on your hair, scalp, or skin for a longer period or use it more often than directed. Your condition will not clear faster, but side effects may be increased.
If your condition worsens or does not improve, tell your doctor or pharmacist promptly.
Skin irritation, dry skin, oily or dry hair/scalp, or temporary hair loss may occur. If any of these effects last or get worse, discontinue use and consult your doctor or pharmacist promptly.
