Withdrawal Periods
Directions for Use
Shake well before use.
Apply in two lines, on both sides of the spinal column from the poll of the head to the tail root.
Apply onto clean, dry skin. Do not apply to wet animals — if rain occurs within 2 hours of application, product effectiveness may be reduced.
Use a squeeze bottle with dosemeter. Squeeze the required volume into the dosemeter before application.
Treat animals at regular intervals according to tick challenge and parasite burden.
Special Management Guidelines
Pyrethroid Resistance Management: Alphatic Double Action contains Fipronil, which acts on GABA receptors — a completely different mechanism from pyrethroids (sodium channel blockers) and amitraz (octopamine receptor agonists). This makes it effective where pyrethroid resistance has developed in tick populations.
Young Stock: Not recommended for calves under 3 months of age. Calves under 6 months must be treated strictly according to body mass.
Lactating Cattle: Do not use on lactating animals where milk is intended for human consumption. The avermectin component is excreted in milk.
Rain-Fastness: Do not apply to wet animals. If rainfall occurs within 2 hours of application, efficacy may be reduced and re-treatment may be necessary.
Meat Withdrawal: The 105-day meat withdrawal period is significantly longer than other pour-on products. Ensure all treated animals are clearly identified and records maintained to prevent premature slaughter.
Internal Parasite Monitoring: While Alphatic Double Action provides broad-spectrum roundworm control, regular faecal egg counts are recommended to monitor parasite burden and guide treatment intervals.
Tick-Borne Disease Immunity
Important Advisory: Correct, regular treatment may reduce natural exposure to ticks and may affect tick-borne disease immunity, especially in young animals. Seek veterinary advice where tick-borne diseases are prevalent. Where possible, vaccinate against tick-borne diseases.
Precautions
First Aid
If swallowed, do not induce vomiting. Seek medical attention immediately and make this label available to the attending physician. If skin contact occurs, wash thoroughly with soap and water. If eye contact occurs, rinse with clean water for at least 15 minutes. In all cases of suspected poisoning, consult a doctor immediately.
