Hydrocyn Aqua Wound Care & Irrigation Solution (Cap Closure)

Hydrocyn Aqua Wound Care & Irrigation Solution (Cap Closure) contains Hypochlorous Acid (HOCl), Purified Water and Sodium Chloride (as a stabilizer) and is presented as a solution. It is supplied in pack sizes of 250ml and 500ml.

It is classified as an over-the-counter (OTC) medicine, so no prescription is needed to order it. Under Malaysian rules for medicine information, this page carries product, safety and handling information only.

You can consult a doctor or pharmacist online on DoctorOnCall about this product before or after you order. Every order is checked by a registered pharmacist before it is delivered. Always read the label and the leaflet supplied with the pack.

Wash your hands thoroughly before handling the bottle or the affected area. Open the cap and pour the solution directly onto the wound or affected area, or soak a sterile gauze pad with the solution and use it to clean the area. The product does not require rinsing off after application.

Repeat 2 to 3 times daily, or as recommended by a healthcare professional, using a fresh sterile gauze pad for each application. Close the cap tightly and securely immediately after each use to help keep the remaining solution free from contamination.

Not applicable in the conventional sense — Hydrocyn Aqua is a topical solution for external application to the skin or a wound surface, as directed on the product packaging or by a healthcare professional. It is not intended for oral ingestion, injection, or internal/systemic use.

Use Hydrocyn Aqua before the expiry date printed on the bottle or outer carton. A universal in-use (after-opening) shelf life is not independently verified for Malaysian retail packaging, so once opened, follow any in-use period stated on the product label, and discard the bottle if the solution appears discoloured or cloudy, or has an unusual odour, even before the printed expiry date.

Store the bottle at room temperature, away from direct sunlight, heat sources, and moisture. Close the cap tightly between uses to help keep the solution stable and free from contamination. Store out of reach of children, and do not freeze the product.

• Common: A mild, brief stinging, tingling, or cooling sensation at the point of application; independent product literature describes Hydrocyn Aqua as generally non-stinging, but individual sensitivity can vary.
• Common: Temporary mild redness of the surrounding skin.
• Serious: Signs of an allergic skin reaction, such as spreading rash, swelling, blistering, or increasing pain, which require prompt medical attention.

• Known hypersensitivity to hypochlorous acid or to any other ingredient in Hydrocyn Aqua.
• Not for oral ingestion or injection.
• Not for use in the eyes unless a specific ophthalmic-labelled product and professional guidance indicate otherwise.

• No clinically significant drug or food interactions are known for Hydrocyn Aqua.
• Applying multiple topical wound-care products to the same area at the same time is not generally recommended without pharmacist or healthcare provider guidance, as this may affect how each product performs on the skin.

• Check the expiry date on the bottle before each use.
• Close the cap tightly and securely immediately after use.
• Use a fresh, sterile gauze pad for each application rather than re-dipping a used one into the bottle.
• Store the bottle away from direct sunlight and heat, and out of reach of children.
• Do not share one opened bottle between different people or different wounds to reduce the risk of cross-contamination.
• Discard the solution if it looks discoloured or cloudy, or has an unusual smell, even if it is not yet past its printed expiry date.

Precautions: Hydrocyn Aqua is intended for topical use on minor, superficial skin conditions. Deep puncture wounds, heavily contaminated or actively infected wounds, animal or human bites, and burns beyond minor/superficial severity generally need professional wound assessment rather than self-care alone. Use in pregnant or breastfeeding women, infants, and young children should follow a healthcare professional’s guidance. Avoid contact with the eyes unless the product is specifically labelled for ophthalmic use.

When to See a Doctor or Pharmacist: Seek professional advice if a wound shows signs of spreading infection, such as increasing redness, swelling, warmth, or pus, or if it is accompanied by fever; if the wound has not shown expected progress after several days of self-care; if pain increases rather than settles; or if any signs of an allergic reaction to the solution occur.
