Qst Syrup belongs to the class of 'anti-malarial drugs', primarily used to treat and prevent malaria. Malaria is a disease caused by a plasmodium parasite transmitted by the bite of infected Anopheles mosquitoes. When an infected mosquito bites a healthy person, it transmits the 'Plasmodium parasite' into the bloodstream, which affects the red blood cells and liver cells. Malaria symptoms usually start ten days to four weeks after the infection. They include chills, high fever, profuse sweating, headache, nausea, vomiting, abdominal pain, diarrhoea, anaemia, muscle pain, convulsions, coma and bloody stools.

Qst Syrup contains Quinine, which treats malaria. It treats malaria by increasing the levels of hemozoin (a toxic substance to the malarial parasite) in the blood. As a result, it kills the parasite and helps to stop the infection from spreading further.

Qst Syrup should be taken as prescribed by the doctor. Your doctor will decide the dose and duration based on your medical condition. Common side effects of Qst Syrup include headache, dizziness, loss of appetite, weakness, fever, chills, tiredness, muscle/joint pain, nausea, vomiting, abdominal pain, cough and trouble sleeping. These side effects are not familiar to everyone and vary individually. If you notice any side effects that are not manageable, please consult your doctor.

Before using Qst Syrup, inform your doctor if you recently used any prescription and non-prescription medications, including other anti-malarial or antibiotic drugs. Let your doctor know if you are allergic to Qst Syrup or its components. Inform your doctor if you have any liver or kidney problems or severe heart diseases. Let your doctor know if you are pregnant, planning to conceive, or a breastfeeding mother. Avoiding alcohol is recommended to rule out any possibility of side effects.

Malaria: Malaria is a life-threatening disease caused by parasites entering the body through mosquito bites. This is a common disease in countries like Africa, South America and Southern Asia. This disease usually occurs when an Anopheles mosquito (infected with the parasite 'Plasmodium') bites a healthy individual and transfers the parasite into the bloodstream. Parasites that cause malaria include Plasmodium vivax, P. ovale, P. malaria and P. falciparum. Malaria symptoms usually start ten days to four weeks after the infection. They include chills, high fever, profuse sweating, headache, nausea, vomiting, abdominal pain, diarrhoea, anaemia, muscle pain, convulsions, coma and bloody stools.
