Frequently asked questions

Emquin 64.5mg Injection is an anti-malarial medicine that is used for the treatment and prevention of malaria.
Symptoms of malaria can develop as quickly as 7 days after you are bitten by an infected mosquito. Usually, the symptoms may take up to 7 to 18 days to appear (incubation periods) from the day of the infection. Initial symptoms of malaria are flu-like which include feeling hot and shivery, fever, muscle pains, vomiting, headaches, and diarrhea.
If your doctor has prescribed you Emquin 64.5mg Injection for a longer period of time, you should get your eyes checked regularly. This is because chloroquine present in this medicine might cause blurred vision, difficulty reading (due to words disappearing), and a rare eye condition called retinopathy if taken for a longer period of time.
Inform your doctor if you have psoriasis before taking Emquin 64.5mg Injection since it may make your condition worse.
Some of the most common side effects of this medicine are stomach pain, nausea, vomiting, and headache. These side effects can often be reduced by taking the medicine with food.
There is not enough medical data to prove that chloroquine is effective in treating COVID-19. Therefore it is advisable not to take Emquin 64.5mg Injection without consulting your doctor for treating COVID-19.
If you take an antacid, give a gap of at least 4 hours between the two medications.
Hydroxychloroquine and chloroquine were both first approved for malaria. However, chloroquine tends to cause many more side effects than hydroxychloroquine. As a result, hydroxychloroquine is more commonly used today. Hydroxychloroquine is also approved to treat rheumatoid arthritis and lupus, while chloroquine is not.
Malaria can be prevented by taking certain precautionary steps like covering your arms and legs to prevent mosquito bites, using a mosquito net, and insect repellent. Check with your doctor whether you need to take malaria prevention tablets. If you do, make sure you take the right antimalarial tablets at the right dose and finish the proper course of treatment.
