Wilisan Yellow Lotion 0.4%

Wilisan Yellow Lotion 0.4% is a topical antiseptic lotion for external use on the skin. Its active ingredient is acriflavine at 0.4% w/v, a yellow-orange acridine dye that has long been used as an antiseptic, and the active ingredient is carried in a liquid lotion base. The product is classified as an over-the-counter (OTC) product and is supplied as a dark yellow liquid in a bottle.

Yellow lotion products are a familiar sight in Malaysian homes and clinics, and Wilisan is a well-known brand of this type. The lotion is a thin, water-like liquid rather than a cream, so it is usually applied with a clean cotton bud or a piece of gauze. Because acriflavine is a dye, the lotion has a strong yellow colour and can temporarily stain skin, clothing and linen.

The product is intended for external use only and must not be swallowed or applied near the eyes. Wilisan Yellow Lotion 0.4% is available in bottle sizes that can vary between listings, so please check the product page and the printed label for the exact volume you are ordering. The full list of inactive ingredients is not consistently published, so please refer to the label on your pack.

Shake the bottle well before use. Clean and dry the skin area first and wash your hands. Dip a clean cotton bud, cotton wool or gauze into the lotion, then apply it gently onto the skin area as directed on the label. Allow the area to air dry.

Use a fresh cotton bud or fresh piece of gauze each time, and do not dip a used applicator back into the bottle, as this can contaminate the lotion. Replace the cap tightly after each use. Wash your hands after application. Avoid contact with the eyes, and avoid applying over large areas of skin.

Apply to the skin area as directed on the product label. This is a topical lotion, so there is no oral dose and no systemic daily dose to calculate. Do not use more often or over a larger area than the label directs, and do not cover the area tightly with an airtight dressing unless advised by a healthcare professional.

If you miss an application, simply apply at the next usual time without doubling up. Do not use this lotion for a prolonged period without medical advice. If the skin becomes more red, painful, swollen or infected-looking, or the problem continues, stop using the lotion and speak with a doctor or pharmacist.

Use before the expiry date printed on the packaging. Once opened, keep the cap tightly closed and do not use the lotion if its colour or appearance has changed.

Store in a cool, dry place away from direct sunlight and heat, with the bottle tightly closed and kept upright. Keep out of the reach of children. Because the lotion can stain, keep the bottle away from fabrics and surfaces.

• Common: Temporary yellow staining of the skin, nails, clothing and bed linen.
• Common: Mild skin irritation, stinging, redness or itching at the application site.
• Serious: Signs of an allergic reaction such as spreading rash, hives, swelling of the lips, face or tongue, or difficulty breathing. Stop use and get urgent medical help, because these can progress quickly.
• Serious: Severe skin burning, blistering or worsening redness and swelling after application. Stop use and seek medical advice, because this can indicate a skin reaction or a spreading skin infection.

• Known allergy or hypersensitivity to acriflavine or any other ingredient in the lotion.
• Do not use near the eyes, inside the mouth or nose, or on mucous membranes.
• Do not swallow; the lotion is for external use only.
• Do not apply to large areas of skin, deep or heavily bleeding wounds, or serious burns unless advised by a healthcare professional.

• No clinically significant interactions with oral medicines are known for this product when it is used on small areas of skin, as little active ingredient is expected to be absorbed.
• Avoid applying other antiseptics, creams, ointments or lotions on the same area at the same time unless a pharmacist has advised it, as they may react with the lotion or change how it behaves.
• No food interactions are known for this product.

• Shake the bottle well before each use so the active ingredient is evenly mixed.
• Use a fresh cotton bud or gauze each time to keep the bottle contents clean.
• Protect clothing, bed linen and nearby surfaces, as the yellow dye can stain.
• Let the area air dry before putting on clothing or a dressing.
• Keep the bottle upright, tightly closed and out of reach of children, as it must not be swallowed.
• Check the expiry date, and stop using the lotion if its colour or clarity has changed.

Precautions: Wilisan Yellow Lotion 0.4% is for external use only and must not be swallowed. Avoid contact with the eyes, and do not apply to large areas of skin, deep wounds or serious burns without medical advice. The lotion stains skin, clothing and linen. Take care in babies and young children, and pregnant or breastfeeding women should check with a pharmacist before use. Do not use for a prolonged period without advice, and stop use if irritation develops.

When to See a Doctor or Pharmacist: See a doctor or pharmacist if the skin becomes more red, painful, swollen, or starts to produce pus, if a rash spreads, if you show signs of an allergic reaction, or if the skin problem continues or worsens despite following the label directions. Seek urgent medical help for any swelling of the face or lips, difficulty breathing, or if the lotion has been swallowed or has entered the eyes.
