Winmal Q 600mg Injection
Price to be Updated
Description
Winmal Q injection is a medicine used to treat chloroquine-resistant Plasmodium falciparum malaria in adults and children over 5 years of age who weigh at least 20 kg. It contains quinine as an active ingredient. It works by killing the malaria parasite in the blood, specifically during the stage where it feeds on haemoglobin. This helps stop the parasite from multiplying and reduces symptoms of malaria.
The injection is given by a doctor or nurse in a hospital or clinic. It is not meant for self-use. After the injection, some common side effects may occur, including nausea, vomiting, ringing in the ears, headache, dizziness, or sweating. A drop in blood sugar and pain at the injection site may also happen, but are usually mild.
This medicine should not be used by individuals who are allergic to quinine or those with conditions such as tinnitus, optic neuritis, blood in the urine, or myasthenia gravis. It needs to be used with caution in people with heart conditions, liver or kidney disease, G6PD deficiency, and those who bruise or bleed easily. Quinine should only be used during pregnancy or breastfeeding if clearly needed and prescribed by a doctor.
Winmal Q injection can interact with many other medicines. Some drugs can increase the risk of side effects, while others can reduce the effectiveness of quinine. These include antifungals, HIV medicines, antibiotics, malaria treatments, epilepsy drugs, and blood thinners. Your doctor may adjust the dose or monitor you closely if you are on these medicines.
The medicine should be stored at a temperature below 25°C, away from sunlight and moisture, and kept out of the reach of children. Since it is administered by healthcare professionals, the risk of overdose or missed doses is low. However, if any signs of overdose or allergic reaction occur, medical help should be sought immediately.

Interactions
Interactions with other medicines
- Some medicines can increase quinine levels in the body (like antifungals and HIV drugs), which may lead to more side effects.
- Other medicines can reduce quinine's effectiveness (such as rifampicin, carbamazepine, and phenytoin), making it less effective.
- Quinine can affect heart rhythm, especially if taken with other heart or antibiotic medicines that also affect the heart (like amiodarone or moxifloxacin).
- Quinine can interact with malaria drugs, like mefloquine, chloroquine, and artemether/lumefantrine, leading to reduced effectiveness or increased risk of side effects.
- It can raise or lower levels of other medicines such as digoxin, ciclosporin, and diabetes medications, so your doctor may need to adjust the doses.
- Combining with blood thinners or epilepsy drugs may require close monitoring due to increased risk of side effects or changes in drug levels.
