However, because of widespread resistance, chloroquine is no longer recommended for Plasmodium falciparum malaria in most parts of the world. For Plasmodium vivax malaria, chloroquine is used in areas where the parasite remains sensitive, followed by primaquine to prevent relapse. Always follow national malaria treatment guidelines and your doctor's advice. |
| ICMR Guideline | The Indian Council of Medical Research recommends chloroquine for the treatment of uncomplicated malaria caused by chloroquine-sensitive Plasmodium vivax and Plasmodium falciparum in areas where resistance is not present. In India, chloroquine is generally not recommended for Plasmodium falciparum malaria because of widespread resistance.

🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine belongs to the 4-aminoquinoline class. After entering the malaria parasite, it concentrates in the acidic food vacuole and prevents the parasite from breaking down haemoglobin. This blocks the formation of harmless haemozoin crystals and allows toxic haem to build up, which kills the parasite. In inflammatory conditions, this medicine also reduces immune cell activity and stabilises cell membranes, which helps control inflammation.
Mechanism Steps
💡 How to Take quinross 250mg tablet

Dosage Information
| Adult Dosage | The dose of this medicine depends on the condition being treated, the severity of the illness, and your age, weight, kidney function, and liver function. For malaria treatment, a common adult regimen is an initial dose followed by additional doses over the next two to three days, but the exact schedule must be determined by your doctor. For malaria prevention, the dose and schedule are different and must be prescribed by a qualified clinician. For inflammatory conditions, lower doses are used under specialist supervision. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Never change the dose or duration without consulting your doctor. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. The dose for children depends on body weight and the condition being treated. It must be calculated and prescribed by a qualified pediatrician. |
| Elderly Dosage | Older adults may be more sensitive to the side effects of this medicine, especially dizziness, blurred vision, and heart rhythm problems. Kidney and liver function often decline with age, so the dose may need to be adjusted. Your doctor will decide the right dose based on your overall health and kidney function. |
| Renal Impairment | This medicine is removed from the body mainly by the kidneys. In people with kidney disease, the medicine can accumulate and increase the risk of side effects. Your doctor may need to reduce the dose or extend the time between doses. Regular monitoring of kidney function is recommended. |
| Hepatic Impairment | This medicine is partly broken down in the liver. In people with liver disease, the medicine can accumulate and increase the risk of side effects. Your doctor may need to reduce the dose or choose a different medicine. Regular monitoring of liver function is recommended. |
| Maximum Daily Dose | The maximum daily dose of this medicine depends on the condition being treated and must be determined by a qualified clinician. Do not exceed the dose prescribed by your doctor. For malaria treatment, the total dose is usually given over a few days, and the daily amount varies. For inflammatory conditions, lower daily doses are used. Never take more than the prescribed dose. |

Kidney and liver function often decline with age, so the dose may need to be adjusted. Your doctor will decide the right dose based on your overall health and kidney function. Regular monitoring of heart rhythm, blood sugar, and vision is recommended for older adults taking this medicine.
🤰 Pregnancy Planning (TTC)
If you are planning to become pregnant, talk to your doctor before taking this medicine. Chloroquine can cross the placenta and may affect the developing baby. Your doctor will consider the risks and benefits and may recommend an alternative medicine. If you become pregnant while taking this medicine, contact your doctor immediately.
🏥 Post-Surgery Considerations
If you are scheduled for surgery, tell your surgeon and anaesthetist that you are taking this medicine. It can affect heart rhythm and blood sugar levels, which may be important during surgery. Your doctor may ask you to stop the medicine before surgery or monitor you more closely during and after the procedure.
🦷 Dental Procedures
Tell your dentist that you are taking this medicine before any dental procedure. It can cause dry mouth and affect blood sugar levels, which may influence your dental care. If you are having a procedure that requires sedation, inform the dentist and anaesthetist about this medicine because it can affect heart rhythm.
💚 Lifestyle Tips for Better Results
🏋️ Exercise Considerations
You can continue light exercise if you feel well, but avoid strenuous activity while you are recovering from malaria or if you feel dizzy, weak, or short of breath. This medicine can cause dizziness and blurred vision, so avoid activities that require sharp focus, such as cycling or lifting heavy weights, until you know how the medicine affects you. If you have heart problems, talk to your doctor before starting any exercise programme.
🥗 Diet Recommendations
💼 Impact on Daily Work & Life
This medicine can cause dizziness, blurred vision, and fatigue, which may affect your ability to drive or operate heavy machinery. Avoid driving or using machinery until you know how the medicine affects you. If your work involves operating dangerous equipment, ask your doctor whether you need to take time off. Most people can continue their normal daily activities with caution, but you should rest if you feel unwell. Malaria itself can cause severe fatigue, so allow yourself time to recover.
🛑 When to Stop This Medicine
Do not stop taking this medicine without talking to your doctor. You should complete the full course of treatment as prescribed, even if you feel better, to make sure the infection is fully cleared. If you develop serious side effects such as severe dizziness, fainting, irregular heartbeat, vision changes, or difficulty breathing, stop the medicine and seek immediate medical help.

Regular eye examinations, hearing tests, and heart monitoring are recommended for anyone taking this medicine for more than a few weeks. The risk of side effects increases with higher doses and longer duration of treatment. Your doctor will review your treatment regularly and may stop the medicine if side effects develop.
