Zyric is used to reduce or prevent the formation of uric acid deposition in a condition where your body releases too much of a substance called uric acid. These conditions may include gout/gouty arthritis, kidney stones, or certain other types of kidney disorders, or when you are having treatments for cancer or some other conditions.

In the case of gout, the uric acid gets collected in your joints and tendons as crystals. These crystals contribute to an inflammatory reaction. The inflammation causes the skin around the joints to swell, tender, and be sore even when slightly touched. You can also experience severe pain when the joints are moved.

Zyrik contains the active ingredient Allopurinol, which belongs to a class of medications known as enzyme inhibitors, which act by controlling the speed at which chemical changes occur in the body. It causes a significant reduction in the formation and accumulation of uric acid in the blood and urine. 

The dosage of Zyrik can vary. Always take it exactly as your doctor has told you. You should check with him if you have any doubts regarding using the medicine. Take your Zyrik tablets after a meal, preferably at the same time daily. Taking your medication timely will have the best effects and help you remember when to take the tablets. The medicine is usually taken once a day. Swallow the pill with a glass full of water. It is important to drink as much as fluids during the treatment, and it is recommended that you should drink at least two litres of water a day.

If you have liver or kidney problems, your doctor will prescribe the lowest dose of Allopurinol that best controls your symptoms. There is a possibility that kidney stones may become impacted in the ureter (the tube that connects the kidney to the bladder) while receiving Allopurinol; check with your doctor in such cases. Also, do not stop treatment in between, even if you feel better.

Do not take Zyrik 300 mg if allergic to Allopurinol or any other ingredients in this medicine. Symptoms of an allergic reaction include breathing difficulties, rash, itching, hives, swelling of the face/lips/tongue/throat, or currently dealing with an acute gout attack. Treatment with Zyrik should not be started until an acute gout attack is over. Your doctor may prescribe another medicine to relieve the acute attack of gouty arthritis.

Take special care if you suffer from liver problems, kidney disorders, high blood pressure, or heart disease. Check with your doctor if you are taking medicines to treat high blood pressure, rheumatoid arthritis, bowel diseases, herpes infections, and certain types of cancer.

Common side effects include feeling sick (nausea or vomiting) and skin rash. If you develop a rare hypersensitivity reaction, stop taking Zyric and see a doctor immediately. The signs may include flaking skin, sore lips and mouth, rarely wheeziness, fluttering or tightness in the chest and collapse. If you develop any side effects, talk to your doctor. This involves any possible side effects not listed in this information guide.
