Antiseptic/Disinfectant
Last reviewed June 2026
Who is this for?
Para-chloro-meta-xylenol (PCMX) is an antiseptic and disinfectant chemical that kills bacteria and some fungi on the skin and surfaces by breaking down their cell walls. It is the active ingredient in products like Dettol and Carex Antiseptic Liquid.
Disrupts bacterial and fungal cell membranes by intercalating into lipid bilayers and denaturing membrane proteins, thereby causing cell lysis and preventing microbial proliferation on skin and wound surfaces.

This is NOT a drug you swallow — it is for external use only. For wound cleaning, dilute the antiseptic liquid as directed on the bottle (usually a capful in a small bowl of water) and use it to clean the wound. For bathing, add a capful or two to your bath water. Always follow the dilution instructions on your specific product.
This is not a scheduled medicine, so there is no missed dose to worry about. Simply use it whenever you need to clean a wound or disinfect your skin.
Always dilute the antiseptic liquid before use — using it undiluted directly on skin can cause irritation or chemical burns. Never drink it or use it as a cure for any internal sickness — some people in Nigeria mistakenly drink antiseptics for stomach problems, which is extremely dangerous and can kill. Buy only from reputable pharmacies and check the expiry date.
Do not mix with other antiseptics or disinfectants like bleach, as this can cause harmful chemical reactions. Avoid using it together with other medicated skin creams or ointments on the same area unless your doctor or pharmacist says it is okay.

Is it safe to take Para-chloro-meta-xylenol with your other drugs?
Generally considered safe for external use during pregnancy and breastfeeding when properly diluted, but avoid applying it near the breast area if you are breastfeeding, and consult your doctor if you have concerns.
Store in a cool, dry place away from direct sunlight and heat — Nigerian heat can affect the product over time. Keep the bottle tightly closed and store well out of reach of children, as swallowing it is very dangerous.
