OPYGARD 2%

Important safety and use flags

• Hard dose boundary: the exact label gives 15-30 g only for a 10-15 kg dog. Do not convert this to a g/kg rule or extrapolate below 10 kg or above 15 kg; choose a product with a valid weight-specific dose instead.
• Shake first, dust the entire dog once and rub against the hair until powder reaches skin. Keep powder out of eyes, nose and mouth, prevent inhalation and licking, and stop if accurate full-coat application cannot be achieved safely.
• The broad label names fleas, sucking lice, ticks and biting lice and claims 2-3 weeks against reinfestation. No public exact-product trial supports that duration, and old carbaryl-powder studies conflict; confirm the parasite and reassess response rather than assuming uniform coverage.
• Carbaryl reversibly inhibits cholinesterase. Salivation, vomiting, miosis, visual change, sweating, tremor/fasciculation, muscle weakness, dyspnoea or seizures after excess exposure are an emergency; remove residual dust safely and obtain urgent veterinary toxicology care.
• Do not use during pregnancy or lactation or with hypersensitivity. The label says no known adverse reactions, but gives no frequency denominator or broad post-market dataset; absence of listed events is not proof of negligible risk.
• Do not use simultaneously with another insecticide. Review all flea/tick collars, spot-ons, sprays, shampoos, environmental products and drugs that can affect cholinesterase before treatment; carbaryl is also unstable in alkaline conditions.
• Wear protective clothing, gloves and eye protection; do not eat, drink or smoke during application. Avoid breathing dust, wash exposed skin with soap and water and keep children and other animals away until loose powder has been removed.
• Environmental application is limited by the exact label to corners/places inaccessible to people and pets. Do not dust bedding, food/water areas or general living surfaces indiscriminately; prevent aquatic/environmental contamination and follow local disposal rules.
• Treating one dog does not control all off-host flea stages or every household animal. Use diagnosis-led treatment, clean/vacuum and wash bedding, assess all pets and choose a sustained preventive strategy when reinfestation risk continues.
• Repeat only after three weeks when still indicated. Store below 25 C in the original dry light-protected container, mark first opening and discard after two months; verify exact OPYGARD 2% dog powder and do not substitute similarly named environmental/bird products.
