Benefits of Hydroxy Q Tablet

Treatment of Rheumatoid arthritis
Rheumatoid arthritis is an autoimmune condition that causes joint inflammation, pain, and stiffness. Hydroxy Q Tablet is used to reduce joint swelling, improve mobility, and slow down joint damage. It helps enhance daily functioning and quality of life in people with this chronic condition.

Treatment of Systemic lupus erythematosus (SLE)
Systemic lupus erythematosus (SLE) is a long-term autoimmune disease where the body's immune system mistakenly attacks its own tissues, leading to inflammation and damage in areas like the skin, joints, kidneys, heart, and lungs. People with SLE may experience joint pain, extreme fatigue, rashes, or serious organ involvement. Hydroxy Q Tablet is commonly used to manage SLE by helping reduce flare-ups, improving skin and joint symptoms, and lowering the risk of long-term organ damage. Regular use of this medicine supports better disease control and improves daily life in people living with lupus.

How to use Hydroxy Q Tablet

How Hydroxy Q Tablet works

Hydroxy Q Tablet is a Disease Modifying Anti-Rheumatoid Drug (DMARD). It works by suppressing the overactivity of the immune system that causes inflammation (swelling) and pain in the joints. This slows the progression of the underlying disease. It has also been suggested that hydroxychloroquine may increase insulin sensitivity and improve beta-cell function, thereby improving glycemic control in patients with type 2 diabetes mellitus.

Frequently asked questions

Is Hydroxy Q Tablet effective against novel coronavirus infection?

Hydroxy Q Tablet is currently under study in various clinical trials (research studies in human beings) for the prevention of novel coronavirus infection and treatment of patients with COVID-19 (the illness caused by the novel coronavirus). This medicine has shown some activity against the novel coronavirus in laboratory studies (in vitro studies). However, further evidence is required to conclude that Hydroxy Q Tablet is effective against the novel coronavirus.

Can Hydroxy Q Tablet be used for the prophylaxis of the novel coronavirus infection?

The national task force for COVID-19 (constituted by ICMR) has recommended the use of Hydroxy Q Tablet for the prevention of novel coronavirus infection ONLY in certain high-risk populations (i.e., people at high risk of exposure to the virus) or emergencies. It can be used for prophylaxis in case of asymptomatic healthcare workers involved in the care of suspected or confirmed cases of COVID-19 and asymptomatic household contacts of laboratory-confirmed cases.

Do we need to maintain a stock of Hydroxy Q Tablet?

No, we do not have to maintain a stock of Hydroxy Q Tablet. If you suspect that you have contracted the novel coronavirus infection, consult a doctor immediately and strictly follow their advice. Do not self-administer Hydroxy Q Tablet. Keep in mind that this medicine needs to be taken only if prescribed by a registered medical practitioner.

What is the recommended dose for preventing coronavirus?

Hydroxy Q Tablet is only recommended for preventing coronavirus infection in certain high-risk groups or emergencies. It should strictly be taken as per the dose, frequency, and duration prescribed by your doctor.

How to take the Hydroxy Q Tablet?

Hydroxy Q Tablet should be taken with food or a glass of milk to prevent an upset stomach and nausea. Take it as directed by the doctor, following the prescribed dose and duration, and complete the entire course. It should be used regularly as advised by your doctor. Do not stop taking it without talking to your doctor first. If you have also taken antacids, then take Hydroxy Q Tablet at least 4hours before or after these products.

What to do if someone becomes symptomatic or shows symptoms of novel coronavirus while taking Hydroxy Q Tablet?

Any person who has been prescribed Hydroxy Q Tablet and develops symptoms of novel coronavirus infection (such as high fever, dry cough, tiredness, difficulty in breathing) while taking Hydroxy Q Tablet should immediately consult their doctor. Your doctor will advise if you need to get tested for the novel coronavirus and if you need to be isolated. Follow all the instructions from your doctor.

How long does it take for Hydroxy Q Tablet to start working?

HCQS takes some time to show its effects. It may even take a few weeks or months before you see an improvement in your symptoms of rheumatoid arthritis or other autoimmune diseases. However, it is important that you be patient and keep taking this medication regularly. Your doctor may prescribe some additional medications in the interim for temporary relief from the symptoms.

Does Hydroxy Q Tablet have any effect on vision?

Yes, though uncommon, HCQS can affect vision, especially if taken at higher doses or for a period of time (> 5 years). The symptoms include reading or seeing difficulties (words, letters, or parts of objects missing), sensitivity to light, blurred distant vision, and seeing light flashes or streaks. If you notice any of these symptoms, consult your doctor immediately. Your doctor may carry out various eye tests and then decide if Hydroxy Q Tablet needs to be discontinued. You may also be advised to get certain eye tests done periodically if you have been prescribed HCQS.

Do I need to get any tests done during Hydroxy Q Tablet treatment?

An eye test is required before your treatment with HCQS starts and should be repeated every 12 months. Also, your doctor may advise you to get your blood counts (CBC) and liver function test (LFT) checked regularly. Your doctor may discontinue HCQS if any abnormality is detected.

Do I need to be careful with Hydroxy Q Tablet if I am a diabetic?

Yes, you need to be careful while using HCQS if you have diabetes. HCQS can lower your blood glucose levels to dangerous levels, so much so that you may even lose consciousness(severe hypoglycemia). Keep a regular check on your blood glucose levels, and if it starts to fall, contact your doctor immediately. Your doctor may alter the doses of your anti-diabetic medications as per your blood glucose levels.

I have been on antacids for a long time, which is necessary for me. Can I still take Hydroxy Q Tablet?

Yes, you can take HCQS, provided you keep a gap of at least 4 hours between HCQS and antacid. If this gap is not maintained, then the antacid may interfere with the absorption or working of HCQS. As a result, you may not experience the full benefits of HCQS.
