How to use Dolobid Tablet

Read the Medication Guide provided by your pharmacist before you start using diflunisal and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with a full glass of water (8 ounces or 240 milliliters) unless your doctor directs you otherwise. Do not lie down for at least 10 minutes after taking this drug. Take this medication with food/milk or right after meals to prevent stomach upset.

Swallow this medication whole. Do not crush or chew the tablets. Doing so may increase side effects.

Dosage is based on your medical condition and response to therapy. Do not take more than 1,500 milligrams per day. To minimize side effect risks (such as stomach bleeding), use this medication at the lowest effective dose for the shortest possible length of time. Do not increase your dose or take it more often than prescribed. For ongoing conditions such as arthritis, continue taking it as directed by your doctor. Discuss the risks and benefits with your doctor or pharmacist.

In certain conditions (such as arthritis), it may take up to 2 weeks of regular use before the full benefits of this drug take effect.

If you are taking this drug on an "as needed" basis (not on a regular schedule), remember that pain medications work best if they are used as the first signs of pain occur. If you wait until the pain has significantly worsened, the medicine may not work as well.

Inform your doctor if your condition worsens.

Also, this drug may rarely cause serious (rarely fatal) bleeding from the stomach or intestines. This effect can occur without warning symptoms at any time while taking this drug. Older adults may be at higher risk for this effect.

Talk to your doctor or pharmacist about the benefits and risks of taking this drug.

Precautions

See also Warning section.

Before taking diflunisal, tell your doctor or pharmacist if you are allergic to it; or to aspirin or other salicylates (such as choline salicylate), or other NSAIDs (such as ibuprofen, naproxen, celecoxib); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Kidney problems can sometimes occur with the use of NSAID medications, including diflunisal. Problems are more likely to occur if you are dehydrated, have heart failure or kidney disease, are an older adult, or if you take certain medications (see also Drug Interactions section). Drink plenty of fluids as directed by your doctor to prevent dehydration and tell your doctor right away if you have a change in the amount of urine.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

This drug may make you dizzy or drowsy. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Talk to your doctor if you are using marijuana (cannabis).

This medicine may cause stomach bleeding. Daily use of alcohol and tobacco may increase your risk for stomach bleeding, especially when combined with this medicine. Limit alcohol and stop smoking. Consult your doctor or pharmacist for more information.

Older adults may be more sensitive to the side effects of this drug, especially stomach/intestinal bleeding and kidney problems.

Since diflunisal is related to aspirin, children and teenagers younger than 18 years should not take diflunisal if they have chickenpox, influenza, or any undiagnosed illness without first consulting a doctor about Reye's syndrome, a rare but serious illness.

Interactions

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.

Some products that may interact with this drug include: aliskiren, ACE inhibitors (such as captopril, lisinopril), angiotensin II receptor blockers (such as losartan, valsartan), antacids (regular use), cidofovir, corticosteroids (such as prednisone), digoxin, live influenza vaccine, lithium, methotrexate, pemetrexed, probenecid, "water pills" (diuretics such as furosemide, hydrochlorothiazide, triamterene).

This medication may increase the risk of bleeding when taken with other drugs that also may cause bleeding. Examples include anti-platelet drugs such as clopidogrel, "blood thinners" such as dabigatran/enoxaparin/warfarin, among others.

Check all prescription and nonprescription medicine labels carefully since many contain pain relievers/fever reducers (NSAIDs such as aspirin, ibuprofen, indomethacin, ketorolac or naproxen) which if taken together with diflunisal may increase your risk for side effects. Low-dose aspirin, as prescribed by your doctor for specific medical reasons such as heart attack or stroke prevention (usually 81-162 milligrams a day), should be continued. Consult your doctor or pharmacist for more details.

This medication may interfere with certain lab tests, possibly causing false test results. Make sure lab personnel and all your doctors know you use this drug.
