This is a medication that is often used to treat malaria caused by mosquito bites. Physicians may prescribe this medication to treat some auto-immune diseases such as rheumatoid arthritis, systemic lupus erythematosus, and other conditions not listed in this document. While Hydroxychloroquine sulfate is the active ingredient, it contains other inactive ingredients such as magnesium stearate, titanium dioxide, dibasic calcium phosphate, and others. Hydroxychloroquine belongs to the class of medications called disease-modifying antirheumatic drugs (DMARDs). HCQS 300 mg should not be used in treating coronavirus also known as COVID-19. It also helps to relieve pain in arthritis and reduce skin problems in lupus.

HCQS 300 mg works by suppressing the overactivity of the immune system, which can cause swelling (inflammation), pain, and others. This helps to reduce the underlying disease progression.

The manufacturer of HCQS 300 mg is Ipca Laboratories Ltd.


Usually, the recommended dose is one or two tablets per day (lupus), once a week if you are using HCQS 300 mg to treat malaria, or as directed by your doctor. Take the tablet whole by mouth with a glass full of water and avoid other beverages such as alcoholic drinks because it may increase the risk of side effects. While swallowing do not crush, break, or chew the tablet. To get a better effect you should take the tablets each day and at the same time. If you are using other medicines such as antacids that contain aluminum hydroxide or magnesium, you should take HCQS 300 mg at least 4 hours before or after these medicines. Antacids prevent your body from fully absorbing Hydroxychloroquine. In addition, to reduce stomach upset, you can administer the tablet with food or milk. Inform your healthcare professional if your medical condition does not improve or if it worsens.


Healthcare professionals may prescribe different dosages for their patients. It depends on your response to treatment, the severity of the medical condition, age, other medicines that you may be using, and weight (for children only). If you have doubts about what dosage is better for you, talk with your physician. However, you should continue taking the tablets even when you feel well. It means that if you stop suddenly the treatment symptoms may return and your condition may worsen.


In rare cases, if you administer an increased dose without the doctor’s approval, you may experience an overdose. Stop taking HCQS 300 mg and ask for medical help immediately, if you notice any of the following symptoms. For example severe dizziness, fainting, passing out, breathing problems, and others. Ask your healthcare professional if you have any questions.

Missed Dose

If you forget and miss a dose, you should take it as soon as possible. However, if it is near the time for the next dose, just skip the missed dose and continue the regular treatment. It is not allowed to administer an increased dose to catch up because it also may increase the risk of side effects.


Before using HCQS 300 mg, you should tell your physician if you are allergic to the ingredients of the drug or if you have any other allergies. However, share with your physician your medical history. For example:

  • Enzyme problems (such as glucose-6-phosphate dehydrogenase deficiency-G6PD)
  • Vision or eye problems
  • Hearing problems
  • Kidney or liver disease
  • Skin disease (such as psoriasis)
  • Blood disorders (such as porphyria)
  • Seizures
  • Regular or abuse of alcoholic drinks

Hydroxychloroquine may make you drowsy or dizzy. Avoid or limit alcoholic drinks and marijuana (cannabis) during treatment because these effects may increase. In addition, it is not recommended to drive or operate machinery while you are on treatment with HCQS 300 mg because you may experience unwanted results.
