Yes, like most medications, Hcqs 200 can cause side effects—but not everyone experiences them. Most people tolerate it well, especially when taken at the right dose and under a doctor’s care. Common side effects include nausea, stomach upset, headache, and dizziness. These are usually mild and go away with time.
However, in rare cases, more serious side effects can occur. These may include vision changes, muscle weakness, or heart rhythm issues. Long-term use, especially in high doses, can sometimes affect the eyes—so regular eye checkups are recommended if you’re using it for conditions like lupus or rheumatoid arthritis.
It’s important to take hydroxychloroquine exactly as prescribed and to tell your doctor about any symptoms you notice. Never stop or adjust the dose on your own. With the right monitoring, hydroxychloroquine is a safe and effective treatment for many autoimmune and inflammatory conditions.
