Salonpas Patch Large

Salonpas Patch Large is a topical medicated patch manufactured by Hisamitsu and sold in Malaysia through DoctorOnCall. It is a large-format adhesive patch designed to be applied directly onto clean, dry skin, and is intended for external use only. The patch is part of the long-established Salonpas range of topical counterirritant products, which have been sold in Malaysia for many years as an over-the-counter option available without a prescription.

Each patch is formulated with three active ingredients working together in a single adhesive layer: Methyl Salicylate (10%), Menthol (6%), and Camphor (3.1%). Methyl Salicylate is a salicylate ester related to aspirin, Menthol is a naturally derived cooling compound extracted from mint oil, and Camphor is a terpenoid compound long used in topical preparations. Together these place Salonpas Patch Large in the topical analgesic patch (counterirritant) product class, distinct from oral tablets, capsules, or liquid rubs. The patch itself uses a thin, flexible, breathable fabric backing with a skin-friendly adhesive designed to stay in place through normal daily movement.

Salonpas Patch Large is distinguished from the standard Salonpas patch primarily by its larger surface area, making it suited to covering broader areas of skin in a single application. It is supplied in sealed foil sachets or packets to protect the medicated adhesive layer from air and moisture prior to use, and is available from DoctorOnCall in standard retail pack sizes. As an externally applied product, it is intended for adults and older children as labelled, and should always be used strictly according to the instructions printed on the packaging and sachet insert.

Wash and dry the area of skin where the patch will be applied, making sure it is free of lotion, oil, or other topical products. Open the sachet immediately before use and peel away the protective backing film without touching the adhesive surface with your fingers more than necessary.

Press the patch firmly onto the clean, dry, unbroken skin over the intended area and smooth it down at the edges so it adheres evenly. Do not apply the patch to broken, irritated, sunburnt, or recently shaved skin, and avoid areas near the eyes, mouth, or mucous membranes.

Only one patch should be worn on a given area of skin at any one time. Once removed, discard the used patch safely, out of reach of children and pets, as it retains active ingredient even after use. Wash your hands thoroughly with soap and water after applying or removing the patch.

For adults and children aged 12 years and above, up to 3 to 4 patches may be applied to different areas of skin within a 24-hour period, with each patch left in place for approximately 8 to 12 hours before being removed. Do not apply more than one patch to the same area of skin at the same time, and allow a rest period before applying a fresh patch to the same site.

Do not exceed the maximum frequency stated on the product packaging. Younger children, pregnant or breastfeeding women, and anyone uncertain about the correct dose should check with a pharmacist or doctor before use, since dosing has not been separately established for all these groups.

Use before the expiry date printed on the packaging. Do not use the patch if the sachet seal is broken, damaged, or has been opened for longer than recommended, as the adhesive layer can dry out and the active ingredients can lose potency once exposed to air.

Store Salonpas Patch Large at room temperature, below 30°C, in a cool, dry place away from direct sunlight and humidity. Keep each patch in its original sealed sachet until immediately before use, and reseal or discard opened packaging promptly to prevent the adhesive from drying out.

Keep the product out of reach and sight of children and pets at all times, both before and after use, since used patches still contain active medication. Do not store in the bathroom or near a sink where humidity is high, and do not store in a vehicle exposed to high temperatures.

• Common: Mild redness or warmth at the site where the patch was applied.
• Common: A temporary tingling, cooling, or mild burning sensation on the skin during wear.
• Common: Itching or minor skin irritation around the edges of the patch, particularly with sensitive skin.
• Serious: Signs of an allergic skin reaction such as spreading rash, blistering, swelling, or hives, which need prompt medical attention as they may indicate sensitivity to salicylates or other ingredients.
• Serious: Severe skin blistering, chemical burn-like injury, or persistent pain at the application site, which should be assessed by a doctor or pharmacist without delay.

• Known allergy or hypersensitivity to methyl salicylate, aspirin, other salicylates, menthol, camphor, or any other component of the patch.
• Application to broken, wounded, infected, or severely irritated skin.
• Use on children under the age recommended on the packaging, unless advised by a doctor or pharmacist.
• Use together with a heating pad, hot water bottle, heating device, or tight bandage over the patch, as added heat can increase absorption and the risk of skin burns.
• Use immediately before or after bathing, showering, swimming, or vigorous exercise that causes heavy sweating, as this may increase skin irritation.

• People taking oral anticoagulant medicines such as warfarin should check with a doctor or pharmacist before using this patch, as salicylate absorbed through the skin can add to the effect of blood-thinning medicines.
• Avoid applying this patch to the same area of skin as other topical products containing menthol, camphor, methyl salicylate, or other salicylates, since combined use may increase the risk of skin irritation or excess absorption.
• There are no known food interactions with this product, as it is applied to the skin rather than swallowed.

• Test a small patch of skin first if you have sensitive skin or have never used a salicylate-based patch before.
• Apply the patch to a flat area of skin for the best, most even adhesion.
• Trim the patch to a smaller size with clean scissors if needed for smaller areas, keeping the backing on the unused portion for later use.
• Remove the patch slowly and gently to reduce the chance of skin irritation, especially on more sensitive skin.
• Keep opened sachets sealed in a resealable bag or container if not used immediately, to prevent the adhesive from drying out.
• Dispose of used patches by folding the adhesive sides together before placing in household waste, away from children and pets.

Precautions: Use this patch on intact, dry skin only, and avoid contact with the eyes, mouth, nose, or other mucous membranes. Pregnant or breastfeeding women, and anyone with known sensitivity to aspirin or other salicylates, should speak with a doctor or pharmacist before use. Do not use on more than one area of skin at the same time without professional advice, and do not use for longer than the period stated on the packaging without checking with a healthcare professional.

When to See a Doctor or Pharmacist: Seek medical advice if skin irritation, redness, or itching at the application site does not improve after removing the patch, or if you notice signs of an allergic reaction such as widespread rash, swelling, or difficulty breathing. Also consult a doctor or pharmacist if you need to use the patch for an extended period, if you are on blood-thinning medicine, or if you are unsure whether this product is suitable for your skin condition.
