How does HCQS 400 mg work?
It works on the immune cells and the chemical signals that cause inflammation. In conditions such as lupus and rheumatoid arthritis it may reduce excessive immune activity that contributes to swelling, pain, rashes and disease flare-ups.
For malaria, the medicine acts inside infected red blood cells and disrupts functions needed by susceptible malaria parasites. Its usefulness depends on the type of malaria parasite and local resistance patterns, so malaria treatment should always follow medical advice.
Usages

Dosage
The appropriate dose of HCQS 400 mg depends on the diagnosis. Doctors usually calculate long-term hydroxychloroquine doses based on actual body weight to lower the chance of retinal toxicity.
A HCQS 400 mg tablet may be prescribed once daily, on alternate days or as part of a different dosing schedule. Follow the prescription label exactly. Do not change the dose, use an extra tablet or share the medicine with another person.

Pharmacokinetics
After oral administration, hydroxychloroquine is absorbed effectively and usually reaches peak blood levels within approximately 3 to 4 hours. Its oral bioavailability is around 74%, although this may vary between individuals.
The medicine spreads extensively into tissues, including the liver, kidneys, lungs, spleen, skin and blood cells. Because it remains stored in tissues, hydroxychloroquine leaves the body slowly and has a long terminal half-life of approximately 40 to 50 days. Roughly 40% to 50% is eliminated through the kidneys which is why people with reduced kidney function may require closer medical supervision.
Precautions
HCQS 400 mg Tablet can worsen the conditions like:
- Allergy
- Liver/ Kidney Diseases
- It should be used with caution due to the increased risk of side effects such as dizziness, fainting, and drowsiness
- You must always consult your doctor to get best possible treatment when you are suffering from any of these conditions.
Hydroxychloroquine should be kept out of reach of children. Even a small overdose can be dangerous in children and requires immediate emergency care.
Discuss pregnancy plans, pregnancy, or breastfeeding with your prescribing doctor. In some patients with lupus or related autoimmune disorders, continuing hydroxychloroquine may be appropriate, but this decision should be individualized.
