Avloclor (Chloroquine Phosphate) 250mg

Taking chloroquine together with certain other medicines can have dangerous effects on your heart. If you experience fast or pounding heartbeats or sudden dizziness (like you might pass out), seek emergency medical attention. A long-term or high dose of chloroquine could cause irreversible damage to the retina of your eye, leading to permanent vision problems. Chloroquine may not be suitable for you if you have a history of vision changes or retinal damage. Do not take chloroquine if you experience blurred vision, difficulty focusing, distorted vision, blind spots, difficulty reading, hazy or cloudy vision, or increased sensitivity to light.

Adults: Two tablets taken once a week, on the same day each week. Start one week before exposure to risk and continue until four weeks after leaving the malarious area. Children: A single dose of 5mg chloroquine base/kg per week on the same day each week. Start one week before exposure to risk and continue until four weeks after leaving the malarious area.

Each 250 mg tablet contains chloroquine phosphate, which is equivalent to 155 mg chloroquine base.
