The Role Of Physical Activity In Prevention Of Gout
Along with diet, physical activity can help with weight loss, and gout has been associated with being overweight.7 in patients with well-established gout, especially if X-rays have demonstrated joint damage in the foot, a low-impact exercise program is reasonable. An exercise program combined with diet in gout can reduce risk for attacks.7 If an attack seems to be coming on in the lower extremity, patients are well-advised to try to get off their feet, since impact seems to worsen gout attacks. Clues to an attack of gout coming on include local swelling, heat, redness, and tenderness in a joint, especially in the foot, ankle, or knee. Some patients have fever and chills as the first warning that an attack of gout is coming on.
Allopurinol And Renal Impairment
One of the only ways allopurinol will be forbidden from therapy in gout is related to renal impairment. Patients with kidney damage can have life-threatening complications when they start using allopurinol, either in the acute or the chronic phase. Renal injury is a risk factor to develop a condition called allopurinol hypersensitivity syndrome.
Allopurinol hypersensitivity syndrome is a severe systemic reaction to allopurinol. It includes symptoms such as fever, skin manifestations, eosinophilia , and multiorgan dysfunction. There is a 25% mortality in patients who develop this syndrome, which is quite high and alarming. Thus, even though there are guidelines to prevent this from happening, doctors might prefer to use other urate-lowering alternatives in this group of patients.
In a nutshell, the main goal of allopurinol is to lower uric acid levels in chronic gout patients. There is current debate on the matter, but the majority of doctors agree that initiating allopurinol in patients recently diagnosed with acute gout is not recommended and does not have any benefit. It is only maintained in patients with chronic gout under treatment with allopurinol, and the only side effect doctors will try to avoid is allopurinol hypersensitivity syndrome, which is more common in patients with renal impairment.

Do Side Effects Of Allopurinol Vary By The Tablet Strength
Its possible that some side effects of allopurinol may be more severe or more likely to occur with a high strength. But your doctor wont start your treatment with a high strength of the drug. Instead, theyll typically start you with a low dosage and slowly increase it over time.
If you develop a skin rash or other serious side effects at any dose, your doctor will have you stop taking allopurinol oral tablets.
If you have other questions about the side effects of allopurinol oral tablets, talk with your doctor or pharmacist.

Interactions That Increase Your Risk Of Side Effects
- Side effects from allopurinol: Taking allopurinol with certain medications raises your risk of side effects from allopurinol. This is because the amount of allopurinol in your body is increased. Examples of these drugs include:
- Ampicillin or amoxicillin. You may have an increased risk of a skin rash.
- Thiazide diuretics, such as hydrochlorothiazide. You may have an increased risk of allopurinol side effects. These include skin rash, diarrhea, nausea, changes in your liver function test results, and gout flare-ups.
- Cyclosporine. Taking allopurinol with cyclosporine may increase cyclosporine levels in your body. Your doctor should monitor your cyclosporine levels and adjust your dose if needed.
This drug comes with several warnings.
Clinical Features And Pathogenesis
Gout is characterised by the acute onset of excruciating joint pain, with associated swelling, erythema and tenderness. The first metatarsophalangeal joint is most commonly affected in the first attack .
Always consider bacterial infection in the differential diagnosis. Other causes of an acute monoarthritis include other crystal arthropathies, such as pseudogout, osteoarthritis, trauma, and rheumatoid and seronegative arthritis.
Gout can be diagnosed on the basis of good history-taking and examination, but when in doubt, the affected joint should be aspirated.
The underlying risk factor for gout is an elevated serum uric acid level, but not all patients with hyperuricaemia will develop the disease. Hence, the clinician should be wary of checking a uric acid level in a well person with no history of gout. The diagram below summarises the pathogenesis of gout which is important to appreciate, in order to understand the aim of therapeutic treatment.

Typical Dosing For Allopurinol
The daily dose of allopurinol will depend on your body’s levels of uric acid. The dose can be taken once a day or in divided doses throughout the day. The maximum daily dose is 800 mg. The typical starting dose for each indication is:
Gout: 100 mg daily
High uric acid in cancer: 600-800 mg daily for 2 or 3 days with lots of fluids
Recurrent kidney stones: 200-300 mg daily
The Difference Between Acute And Chronic Gout
The first step we should take is to differentiate acute and chronic gout. They are different manifestations of the same disease. Gout is not only diagnosed after blood tests with high levels of uric acid. This is called hyperuricemia. The diagnosis of gout requires a physical and functional examination to evidence that the articulations of the patient are being affected by such levels of uric acid in the blood. Otherwise, hyperuricemia is not diagnosed as gout.
Circled in Red is a Patient with Gout caused by Excessive Allopurinol
Acute gout is characterized by severe pain located in the toes or hands, but not limited to them. The symptoms appear suddenly, sometimes in the middle of the night, and become unbearable and very severe.
The area becomes swollen, red, tender, and very warm because theres a severe inflammatory process triggered by uric acid crystals. Pain in acute gout may last for hours, days, and sometimes a whole week. But after the attack has gone, the patient does not display any symptoms.

What Other Information Should I Know
Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body’s response to allopurinol.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.

A second way that allopurinol helps prevent gout flares is by driving or forcing xanthines and hypoxanthines to combine into new DNA/RNA productionthat way some of them become unavailable to make uric acid. This effectively lowers uric acid blood levels because there is less material available to make uric acidhence fewer gout attacks.

Lowering Uric Acid Can Cause Pain
At the correct dose, all uric acid lowering treatments will cause uric acid crystals to dissolve. Remember, this is what we must do to avoid skin-bursting tophi and crippling joint deposits.
Unfortunately, as they are dissolving, uric acid crystals shed the protein coating, and the immune system starts to attack again, which may result in a painful gout flare. You must be prepared for this, and discuss with your doctor whether you take anti-inflammatory pain relief with the allopurinol medication, or take pain relief when a gout flare occurs.
How Does Allopurinol Work
Allopurinol helps reduce urate levels in your blood and reduces gout attacks. Uric acid is a normal product of your metabolism and in the blood, uric acid becomes urate. When urate levels are high, crystals can form around joints causing inflammation, pain and damage. This is known as gout.To reduce gout attacks, it is important to keep your serum urate level below 0.36 mmol/L. When the serum urate is below 0.36mmol/L no new crystals form and crystals that are in your joints or skin can dissolve. Read more about gout.

Taking Allopurinol With Painkillers
Your doctor may prescribe a NSAID (such as diclofenac or naproxen or a medicine called colchicine to help prevent or to deal with attacks of gout especially in the early stages of allopurinol treatment.
What This Means For You
Stamp encourages patients to take control. If your gout is managed well, you should have no gout attacks. If you are still having regular attacks or have tophi, talk to your doctor. It is important that your blood uric acid levels are checked and your urate-lowering medicines adjusted to reduce your uric acid and improve your symptoms.
Dr. Kay agrees. Reducing the total body urate burden will improve control of gouty arthritis, and perhaps improve hypertension and reduce cardiovascular morbidity as well, he says.Beth Axtell for the Arthritis Foundation

How Can An Attack Of Gout Be Treated
The management of an acute attack of gout is very different from the prevention of subsequent attacks.
Treatments used for prevention, such as allopurinol can actually make things worse if given during an attack, and so need to be held back until the attack has resolved for several weeks.
There are a number of measures that can help resolve an attack of gout. See Table 2 for summary of treatment strategies for acute gout. One principle is that treatment for an attack of gout should be instituted quickly, since quick treatment can often be rewarded with a quick improvement.
If an attack of gout is allowed to last more than a day or so before treatment is started, the response to treatment may be much slower.
Table 2: Medications to treat acute attacks of gout
Deal With The Pain Of Allopurinol Medication
All too often gout sufferers concentrate on finding pain relief and forget about the dangers of a long-term buildup of uric acid crystals.
You must understand the dangers of uric acid, how crystals can cause serious damage, often without pain, and how lowering uric acid might temporarily increase pain.
Distinguishing between pain relief and lowering uric acid is crucial for managing gout. Understand it, and you are less likely to fail. Do not be one of the gout patients who fail to get rid of gout because you do not understand allopurinol medication.

The Irony Of Allopurinol
Allopurinol is an acclaimed very effective medication in the reduction of uric acid. Coming along with this is febuxostat, these two are the most common of all the medications that help in lowering the uric acid.
In spite of being recommended as a medication for gout, the allopurinol may worsen the gout attacks. The pain may become more severe and more intense. This has something to do with the mechanism of the allopurinol.
The allopurinol, as we know, is a xanthine oxidase inhibitor. Meaning, it prevents the xanthine oxidase enzyme from responding with purine. If the purine doesnt react with the xanthine oxidase, it isnt broken down into uric acid.
Simply speaking, the allopurinol ensures the binding with the xanthine oxidase rather than having purine bind with the enzyme. It just distracts the xanthine oxidase.
Now, to answer the question why does allopurinol worsen acute gout? we need to understand the mechanism of gout attacks first.
Important Things To Remember
- Once you are prescribed allopurinol it is very important that you do not stop taking it unless advised by your doctor or unless side effects develop. If allopurinol treatment is stopped there is a high risk that your gout may worsen.
- You should continue to take it even if you do not have symptoms.
- You should also continue to take it during an attack of gout.

How Is It Taken
Allopurinol is taken as a tablet once a day. It is usually better to take it just after eating and the tablet should be swallowed with water. It is important to drink plenty of water during the day because this will help you get rid of more urate through your kidneys.
Your dose of allopurinol may change over time, depending on the amount of urate in your body. Your doctor will monitor your urate levels with blood tests every 2-4 weeks, until they are sure that the dose that youre taking is high enough to reduce the amount of urate in your body.
You may need to remain on a lower dose if you have kidney or liver problems.
Your doctor may recommend that you do not start taking allopurinol until after an attack of gout has passed to avoid triggering further attacks. If this is not possible, it may be started when your inflammation is not too bad.
Allopurinol doesnt treat the immediate pain caused by attacks of gout. But its a long-term treatment to get rid of the urate crystals which causes gout attacks.
It is likely that you will need to take allopurinol for the rest of your life to manage your urate levels. You should keep taking allopurinol even if:
- you are experiencing more gout attacks, or it doesnt seem to help the pain and inflammation at first
- you stop having gout attacks stopping your treatment can cause urate crystals to form again, which will lead to more gout attacks.
