Understand the common and serious side effects of Plaquenil (hydroxychloroquine) for Indian readers. Learn about management, risks, and when to seek medical help.
Plaquenil, a medication whose active ingredient is hydroxychloroquine, is a trusted ally for many in managing conditions like rheumatoid arthritis and lupus. However, like all potent medicines, it comes with a set of potential side effects. For our readers in India, understanding these effects, their severity, and how to manage them is paramount. This guide aims to demystify Plaquenil's side effects, offering practical advice and clear guidance, straight from medical insights, to help you navigate your treatment journey with confidence.
Plaquenil (hydroxychloroquine) is prescribed to adults for several key purposes:
It's also used in some children to combat specific types of malaria. It’s vital to remember that Plaquenil is a prescription medication. It should only be taken under the strict guidance of a healthcare professional. The misuse of any prescription drug, including Plaquenil, can lead to adverse outcomes.
While Plaquenil is generally well-tolerated, some individuals may experience side effects. These can range from mild annoyances to more significant concerns. Here are some of the more frequently reported side effects:
Most of these mild side effects are temporary and tend to resolve on their own. Some can be easily managed with simple adjustments. However, if any symptom persists, worsens, or causes significant discomfort, it is essential to speak with your doctor or pharmacist. Never stop taking Plaquenil abruptly unless your doctor explicitly advises you to do so.
While less common, Plaquenil can cause more severe side effects. Recognizing these and acting swiftly is critical for your health. If you experience any of the following, contact your doctor immediately. If the side effects feel life-threatening or you believe you are experiencing a medical emergency, call 108 (India's emergency number) or your local emergency services without delay.
This is one of the most serious potential side effects, especially with long-term use. Plaquenil can affect the retina, potentially leading to irreversible vision loss. Symptoms may include:

Plaquenil can impact heart rhythm and function. Be vigilant for:
If you experience any of these, seek medical attention immediately. Individuals with pre-existing heart conditions should discuss this risk thoroughly with their doctor before starting Plaquenil.
Plaquenil can sometimes affect mood and mental well-being. Watch out for:
If you experience any distressing mental health symptoms, reach out to your doctor, a mental health professional, or the National Helpline for Suicide Prevention (call or text 988). Support is available 24/7, free of charge, and confidential.
Though rare, Plaquenil can affect blood cell counts. Symptoms might include unusual tiredness, paleness, frequent infections, or easy bruising and bleeding. Your doctor may perform blood tests periodically to monitor this.
Signs of liver issues can include jaundice (yellowing of the skin or eyes), dark urine, or severe abdominal pain. Report these symptoms to your doctor at once.
A severe allergic reaction (anaphylaxis) is a medical emergency. Symptoms include:
If you suspect a severe allergic reaction, call 108 or your local emergency number immediately.
Some individuals may experience tinnitus (ringing in the ears), vertigo (a spinning sensation), or hearing loss. If these symptoms are bothersome or persistent, consult your doctor.
Certain factors can heighten your risk of experiencing adverse effects from Plaquenil:
Effective management is key to continuing treatment safely. Here’s how:
You should contact your doctor immediately if you experience:
Even for persistent mild side effects that bother you, a conversation with your doctor is warranted.
The duration of Plaquenil treatment varies greatly depending on the condition being treated. While some people may take it for a few months, others might need it for many years. Long-term use, especially beyond 5 years, increases the risk of certain side effects like vision damage. Your doctor will continuously assess the benefits and risks to determine the appropriate treatment length for you. Regular monitoring, including eye exams, is vital during prolonged treatment.
Yes, Plaquenil can interact with other medicines. It's essential to provide your doctor with a complete list of all medications, supplements, and herbal products you are taking. This includes over-the-counter drugs. Some interactions can increase the risk of side effects or affect how Plaquenil works. For example, certain heart medications might increase the risk of heart rhythm problems when taken with Plaquenil.
If you miss a dose, take it as soon as you remember, unless it is almost time for your next dose. In that case, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are unsure or frequently miss doses, discuss strategies with your doctor or pharmacist.
Plaquenil should generally be avoided during pregnancy unless the potential benefits outweigh the potential risks to the fetus. Its use during breastfeeding also requires careful consideration. Always consult your doctor if you are pregnant, planning to become pregnant, or breastfeeding while taking Plaquenil. They can provide personalized advice based on your health status and the specific risks involved.
Plaquenil is primarily used to help prevent certain types of malaria and to treat malaria that has already developed. However, it is not effective against all forms of malaria, and resistance can occur. For malaria treatment, it's often used in combination with other antimalarial drugs. Always follow your doctor's advice regarding malaria prevention and treatment, especially if you are travelling to malaria-prone regions.
