What is Dolozal?

Dolozal is in a group of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). It works by reducing hormones that cause inflammation and pain in the body.

Dolozal is used to treat mild to moderate pain, osteoarthritis, or rheumatoid arthritis.

Dolozal may also be used for other purposes not listed in this medication guide.

Dolozal indications

Carefully consider the potential benefits and risks of Dolozal (Dolozal) and other treatment options before deciding to use Dolozal (Dolozal). Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals.

Dolozal (Dolozal) is indicated for acute or long-term use for symptomatic treatment of the following:

1. Mild to moderate pain
2. Osteoarthritis
3. Rheumatoid arthritis

How should I use Dolozal?

Use Dolozal as directed by your doctor. Check the label on the medicine for exact dosing instructions.

• Dolozal comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get Dolozal refilled.
• Take Dolozal by mouth. It may be taken with food if it upsets your stomach. Taking it with food may not lower the risk of stomach or bowel problems (eg, bleeding, ulcers). Talk with your doctor or pharmacist if you have persistent stomach upset.
• Swallow Dolozal whole. Do not break, crush, or chew before swallowing.
• Take Dolozal with a full glass of water (8 oz/240 mL) as directed by your doctor.
• If you miss a dose of Dolozal and you are taking it regularly, take it as soon as possible. If it is almost time for your next dose, skip the missed dose. Go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about the proper use of Dolozal.

Uses of Dolozal in details

Osteoarthritis/Rheumatoid arthritis (RA): Treatment of osteoarthritis and RA

Pain, mild to moderate: Treatment of mild to moderate pain

Dolozal description

Dolozal, a salicylate derivative, is a nonsteroidal anti-inflammatory agent (NSAIA) with pharmacologic actions similar to other prototypical NSAIAs. Dolozal possesses anti-inflammatory, analgesic and antipyretic activity. Though its mechanism of action has not been clearly established, most of its actions appear to be associated with inhibition of prostaglandin synthesis via the arachidonic acid pathway. Dolozal is used to relieve pain accompanied with inflammation and in the symptomatic treatment of rheumatoid arthritis and osteoarthritis.

Dolozal dosage

Carefully consider the potential benefits and risks of Dolozal (Dolozal) and other treatment options before deciding to use Dolozal (Dolozal). Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals.

After observing the response to initial therapy with Dolozal (Dolozal), the dose and frequency should be adjusted to suit an individual patient's needs.

Concentration-dependent pharmacokinetics prevail when Dolozal (Dolozal) is administered; a doubling of dosage produces a greater than doubling of drug accumulation. The effect becomes more apparent with repetitive doses.

For mild to moderate pain, an initial dose of 1000 mg followed by 500 mg every 12 hours is recommended for most patients. Following the initial dose, some patients may require 500 mg every 8 hours.

A lower dosage may be appropriate depending on such factors as pain severity, patient response, weight, or advanced age; for example, 500 mg initially, followed by 250 mg every 8-12 hours.

For osteoarthritis and rheumatoid arthritis, the suggested dosage range is 500 mg to 1000 mg daily in two divided doses. The dosage of Dolozal (Dolozal) may be increased or decreased according to patient response.

Maintenance doses higher than 1500 mg a day are not recommended.

Tablets should be swallowed whole, not crushed or chewed.

Dolozal interactions

What other drugs will affect Dolozal?

ACE-Inhibitors and Angiotensin II Antagonists

Reports suggest that NSAIDs may diminish the antihypertensive effect of ACE-inhibitors and angiotensin II antagonists. These interactions should be given consideration in patients taking NSAIDs concomitantly with ACE-inhibitors or angiotensin II antagonists. In some patients with compromised renal function, the co-administration of an NSAID and an ACE-inhibitor or an angiotensin II antagonist may result in further deterioration of renal function, including possible acute renal failure, which is usually reversible.

Acetaminophen

In normal volunteers, concomitant administration of Dolozal (Dolozal) and acetaminophen resulted in an approximate 50% increase in plasma levels of acetaminophen. Acetaminophen had no effect on plasma levels of Dolozal (Dolozal). Since acetaminophen in high doses has been associated with hepatotoxicity, concomitant administration of Dolozal (Dolozal) and acetaminophen should be used cautiously, with careful monitoring of patients. Concomitant administration of Dolozal (Dolozal) and acetaminophen in dogs, but not in rats, at approximately 2 times the recommended maximum human therapeutic dose of each (40-52 mg/kg/day of Dolozal (Dolozal) /acetaminophen), resulted in greater gastrointestinal toxicity than when either drug was administered alone. The clinical significance of these findings has not been established.

Antacids

Concomitant administration of antacids may reduce plasma levels of Dolozal (Dolozal). This effect is small with occasional doses of antacids, but may be clinically significant when antacids are used on a continuous schedule.

Aspirin

When Dolozal (Dolozal) is administered with aspirin, its protein binding is reduced, although the clearance of free Dolozal (Dolozal) is not altered. The clinical significance of this interaction is not known; however, as with other NSAIDs, concomitant administration of Dolozal and aspirin is not generally recommended because of the potential of increased adverse effects.

In normal volunteers, a small decrease in Dolozal levels was observed when multiple doses of Dolozal (Dolozal) and aspirin were administered concomitantly.

Cyclosporine

Administration of non-steroidal anti-inflammatory drugs concomitantly with cyclosporine has been associated with an increase in cyclosporine-induced toxicity, possibly due to decreased synthesis of renal prostacyclin. NSAIDs should be used with caution in patients taking cyclosporine, and renal function should be carefully monitored.

Diuretics

Clinical studies, as well as post marketing observations, have shown that Dolozal (Dolozal) can reduce the natriuretic effect of furosemide and thiazides in some patients. This response has been attributed to inhibition of renal prostaglandin synthesis.

In normal volunteers, concomitant administration of Dolozal (Dolozal) and hydrochlorothiazide resulted in significantly increased plasma levels of hydrochlorothiazide. Dolozal (Dolozal) decreased the hyperuricemic effect of hydrochlorothiazide. During concomitant therapy with NSAIDs, the patient should be observed closely for signs of renal failure, as well as to assure diuretic efficacy.

Lithium

NSAIDs have produced an elevation of plasma lithium levels and a reduction in renal lithium clearance. The mean minimum lithium concentration increased 15% and the renal clearance was decreased by approximately 20%. These effects have been attributed to inhibition of renal prostaglandin synthesis by the NSAID. Thus, when NSAIDs and lithium are administered concurrently, subjects should be observed carefully for signs of lithium toxicity.

Methotrexate

NSAIDs have been reported to competitively inhibit methotrexate accumulation in rabbit kidney slices. This may indicate that they could enhance the toxicity of methotrexate. Caution should be used when NSAIDs are administered concomitantly with methotrexate.

NSAIDs

The administration of Dolozal to normal volunteers receiving indomethacin decreased the renal clearance and significantly increased the plasma levels of indomethacin. In some patients the combined use of indomethacin and Dolozal (Dolozal) has been associated with fatal gastrointestinal hemorrhage. Therefore, indomethacin and Dolozal (Dolozal) should not be used concomitantly.

The concomitant use of Dolozal (Dolozal) and other NSAIDs is not recommended due to the increased possibility of gastrointestinal toxicity, with little or no increase in efficacy. The following information was obtained from studies in normal volunteers.

Sulindac: The concomitant administration of Dolozal (Dolozal) and sulindac in normal volunteers resulted in lowering of the plasma levels of the active sulindac sulfide metabolite by approximately one-third.

Naproxen: The concomitant administration of Dolozal (Dolozal) and naproxen in normal volunteers had no effect on the plasma levels of naproxen, but significantly decreased the urinary excretion of naproxen and its glucuronide metabolite. Naproxen had no effect on plasma levels of Dolozal (Dolozal).

Oral Anticoagulants

In some normal volunteers, the concomitant administration of Dolozal (Dolozal) and warfarin, acenocoumarol, or phenprocoumon resulted in prolongation of prothrombin time. This may occur because Dolozal competitively displaces coumarins from protein binding sites. Accordingly, when Dolozal (Dolozal) is administered with oral anticoagulants, the prothrombin time should be closely monitored during and for several days after concomitant drug administration. Adjustment of dosage of oral anticoagulants may be required. The effects of warfarin and NSAIDs on GI bleeding are synergistic, such that users of both drugs together have a risk of serious GI bleeding higher than users of either drug alone.

Tolbutamide

In diabetic patients receiving Dolozal (Dolozal) and tolbutamide, no significant effects were seen on tolbutamide plasma levels or fasting blood glucose.

Drug/Laboratory Test Interactions

Serum Salicylate Assays: Caution should be used in interpreting the results of serum salicylate assays when Dolozal is present. Salicylate levels have been found to be falsely elevated with some assay methods.
