| WHO Guideline | The World Health Organization recommends quinine as an alternative treatment for severe malaria when artesunate is not available. It should be used in combination with an antibiotic such as doxycycline or clindamycin. For uncomplicated malaria, quinine is not the first-line treatment in most regions due to the availability of artemisinin-based combination therapies. |

It should be given as a slow intravenous infusion initially, followed by oral therapy to complete the course. For uncomplicated malaria, artemisinin-based combination therapy is preferred. |

🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by accumulating in the food vacuole of the malaria parasite, where it interferes with the digestion of hemoglobin. The parasite breaks down hemoglobin to obtain amino acids, releasing toxic heme in the process. Quinine prevents the polymerization of heme into inert hemozoin, leading to the buildup of toxic heme that kills the parasite. Additionally, quinine affects the parasite's membrane transport and may interfere with nucleic acid synthesis. In humans, quinine also has effects on skeletal muscle and the cardiovascular system, which explain some of its side effects and off-label uses.
Mechanism Steps
💡 How to Take quin 9 suspension
Strength: This medicine is available as an oral suspension containing quinine 150 mg per 5 mL. The pack size may vary. Shake well before use.
Dosage Information
| Adult Dosage | The usual adult dose of this medicine for the treatment of severe malaria is 10 mg/kg of quinine base every 8 hours for 7 days, often combined with doxycycline or clindamycin. For chloroquine-resistant malaria, the same regimen is used. The dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function, and the severity of the infection. The suspension should be shaken well before each use and measured with a proper measuring device. Do not exceed the prescribed dose. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician for appropriate dosing in children. |
| Elderly Dosage | Elderly patients may be more sensitive to the effects of quinine, especially cardiac and neurological effects. Dose reduction may be necessary based on renal function. Close monitoring is recommended. |
| Renal Impairment | In patients with severe renal impairment (creatinine clearance less than 10 mL/min), the dose of quinine should be reduced, and the dosing interval may need to be extended. Monitoring of drug levels, if available, is advised. Consult a nephrologist or clinical pharmacist for guidance. |
| Hepatic Impairment | In patients with hepatic impairment, quinine metabolism may be reduced, leading to increased drug levels. Dose reduction and close monitoring for toxicity are recommended. Consult a hepatologist for individualized dosing. |
| Maximum Daily Dose | The maximum daily dose of quinine for adults is typically 30 mg/kg per day, divided into three doses. However, the exact maximum dose must be determined by a qualified clinician based on the patient's condition and response to treatment. |

🤱 Lactation Safety
Quinine is excreted in breast milk in small amounts. It is generally considered compatible with breastfeeding, but the amount ingested by the infant is usually too small to cause harm. However, because of the potential for serious side effects in infants, breastfeeding mothers should consult their doctor before using this medicine. Monitoring the infant for signs of toxicity such as jaundice, poor feeding, or irritability is advised.
💊 Overdose Management
Overdose of quinine can be life-threatening and requires immediate medical attention. Symptoms of overdose include severe cinchonism, cardiac arrhythmias, hypotension, seizures, coma, and respiratory depression. There is no specific antidote. Treatment is supportive and may include activated charcoal if ingestion occurred within 1-2 hours, intravenous fluids, sodium bicarbonate for cardiac toxicity, and management of seizures and arrhythmias. Hemodialysis or hemoperfusion may be considered in severe cases. Patients should be monitored in an intensive care setting.
⏰ Missed Dose
If you miss a dose of this medicine, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take a double dose to make up for a missed one. If you are unsure, consult your doctor or pharmacist.
Additional Safety Advice
This medicine should only be taken under the supervision of a qualified healthcare professional. Do not adjust the dose or stop treatment without consulting your doctor, even if you feel better, because incomplete treatment can lead to relapse and drug resistance. Take the suspension with food or milk to reduce stomach upset. Avoid alcohol while taking this medicine as it can increase the risk of side effects. Inform your doctor about all other medicines you are taking, especially blood thinners, diabetes medications, and heart rhythm drugs. If you have a history of heart problems, kidney or liver disease, or blood disorders, your doctor may need to adjust the dose or monitor you more closely. Do not drive or operate heavy machinery if you experience dizziness or blurred vision. Keep this medicine out of reach of children and store it as directed on the label.
👴 Special Considerations for Elderly
💡 For Patients Above 65
Elderly patients are more susceptible to the cardiac and neurological side effects of this medicine. Dose reduction may be necessary based on renal function. Close monitoring for signs of toxicity is recommended. Falls risk may be increased due to dizziness.
🤰 Pregnancy Planning (TTC)
If you are planning to become pregnant, discuss with your doctor before taking this medicine. Quinine should be used during pregnancy only if clearly needed and under medical supervision. Effective contraception is advised while taking this medicine if pregnancy is not desired.
🏥 Post-Surgery Considerations
Inform your surgeon and anesthesiologist if you are taking this medicine before surgery. Quinine can affect heart rhythm and blood sugar, which may interact with anesthetic agents. Your doctor may advise you to stop the medicine temporarily before surgery.
🦷 Dental Procedures
Inform your dentist if you are taking this medicine. Quinine can cause dry mouth and may interact with certain dental anesthetics. It is important to maintain good oral hygiene and stay hydrated during dental procedures.
💚 Lifestyle Tips for Better Results
🏋️ Exercise Considerations
Avoid strenuous exercise while you are recovering from malaria, as your body needs rest. If you experience dizziness or fatigue, limit physical activity. Consult your doctor before resuming an exercise routine.
🥗 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 machinery. Avoid these activities until you know how the medicine affects you. You may need to take time off work to recover from malaria and to complete treatment.
🛑 When to Stop This Medicine
Do not stop taking this medicine without consulting your doctor. You should complete the full course as prescribed. If you experience serious side effects such as severe dizziness, vision changes, or irregular heartbeat, stop the medicine and seek immediate medical attention. Your doctor will decide if treatment needs to be changed or stopped.
📅 Long-Term Use Effects
Long-term use of this medicine is not recommended unless under strict medical supervision. Prolonged use can increase the risk of cinchonism, blood disorders, and cardiac toxicity. Regular monitoring of blood counts, liver and kidney function, and ECG may be necessary. If you require long-term therapy, your doctor will assess the risks and benefits periodically.
🌿 Non-Medicine Approaches
These can complement medicine but do not replace prescribed treatment.
Artesunate is the preferred treatment for severe malaria and is more effective and safer than quinine when available.
Evidence: Well-establishedFor uncomplicated malaria, ACTs such as artemether-lumefantrine are the first-line treatment.
Evidence: Well-establishedHydration, antipyretics, and rest are important adjuncts to antimalarial therapy.
