CHLOROQUINE is very useful in treating acute attacks of certain strains of malaria and a certain type of parasitic infection (extraintestinal amebiasis) and it works by killing sensitive malaria parasites by stopping normal metabolism inside the parasite.
Following the dosage instructions of your doctor is the best way to use any medication. If you are unsure or do not remember the instructions then you may read the medicine label for more detailed information.
You may choose to take CHLOROQUINE with a meal to avoid an upset stomach or without one. You are advised not to take antacids or products containing kaolin within 4 hours before or after taking Chloroquine.
Taking your medication at the same time each day is a tried and tested method to avoid missing any doses.
Drug Class and Mechanism
CHLOROQUINE falls under aminoquinoline and it works by killing sensitive malaria parasites by stopping normal metabolism inside the parasite.
Despite your best attempts at remembering, if you still miss out on a dose, then take it as soon as you remember about it. But keep in mind that you will have to adjust your next dose by spacing it out by 4 to 5 hours. If this is not possible, then the best thing to do would be to skip the missed dose and continue with your normal dosage schedule.
Never try to compensate for the missed dose by taking a double dose together. It may cause adverse effects.
Store CHLOROQUINE at room temperature between 68 and 77 degrees F(20 and 25 degrees C). Always keep it in a cool dark place that is not directly exposed to sources of heat or moisture and sunlight. Protect it from kids and pets.

Contact your doctor or health care provider right away if any of these apply to you.
