Can HCQS 200mg be used for viral fever? HCQS 200mg is not typically recommended for viral fever, as it is mainly prescribed for conditions like malaria, rheumatoid arthritis, and lupus. Viral fever is usually caused by common viruses that do not respond to hydroxychloroquine. Using HCQS unnecessarily may lead to side effects such as nausea, headache, or vision changes. For viral fever, doctors usually suggest rest, hydration, and fever-reducing medicines like paracetamol. Only use HCQS 200mg if a healthcare professional specifically advises it based on your condition. Click Here : https://www.dosepharmacy.com/hcqs-200mg-tablet-hydroxychloroquine
