Chloroquine

What Is Chloroquine?

Chloroquine is a prescription antimalarial medicine used to treat and prevent malaria infection. Malaria is a serious disease caused by parasites that enter the body through the bite of infected mosquitoes. It can cause high fever, chills, sweating, headache, and body weakness.

Doctors prescribe Chloroquine tablets mainly in areas where malaria parasites are still sensitive to this medicine.

A general physician or infectious disease specialist usually prescribes Chloroquine after confirming malaria through blood tests.

Chloroquine belongs to the antimalarial drug group.

An antimalarial medicine is a drug that kills malaria-causing parasites in the blood.

What This Medicine Does in the Body

Chloroquine works by killing malaria parasites inside the red blood cells.

After a mosquito bite, malaria parasites enter the bloodstream and start multiplying inside red blood cells. This causes fever, chills, and weakness.

Chloroquine enters infected red blood cells and stops the parasite from using essential substances it needs to survive.

This leads to the death of the parasite and helps stop the spread of infection in the body.

As the parasite count decreases, symptoms like fever, chills, sweating, and body pain gradually improve.

This medicine does not work for viral infections like cold or flu. It is specifically used for malaria caused by parasites.

Uses of Chloroquine / Used For

Doctors mainly use Chloroquine for malaria treatment and prevention.

It is used to treat uncomplicated malaria, where the infection is mild to moderate and detected early.

A general physician may also prescribe it for malaria prevention (prophylaxis) in people traveling to malaria-prone areas.

In some cases, it has been used for certain inflammatory conditions, but this depends on medical guidelines and doctor advice.

Chloroquine is not used for common fever, viral infections, or bacterial infections. It is only effective against malaria parasites.

How Chloroquine Works

Chloroquine works by attacking the malaria parasite inside red blood cells.

The malaria parasite feeds on hemoglobin inside red blood cells to survive. During this process, it produces toxic waste.

Normally, the parasite removes this waste to stay alive.

Chloroquine blocks this process and allows toxic substances to build up inside the parasite.

As toxins increase, the parasite dies, and infection starts to clear from the bloodstream.

With regular treatment, symptoms like fever and chills reduce as parasite levels drop.

Doctors prescribe it for a fixed duration to fully clear the infection and prevent relapse.

Side Effects of Chloroquine

Like all medicines, Chloroquine may cause side effects. Most are mild and temporary.

Common side effects include nausea, vomiting, headache, dizziness, and stomach discomfort.

Nausea means feeling like vomiting.

Vomiting means emptying the stomach through the mouth.

Dizziness means feeling lightheaded or unsteady.

Some people may also experience blurred vision or itching of the skin.

Rare but serious side effects include changes in vision, severe weakness, or irregular heartbeat.

Patients should inform a doctor if they notice vision problems or severe side effects.

A doctor should supervise treatment and adjust the dose when needed for safety.
