Diacerein is a prescription medication specifically formulated for the management of osteoarthritis symptoms. As a disease-modifying osteoarthritis drug (DMOAD), it works by inhibiting interleukin-1 beta, a key cytokine involved in cartilage degradation and inflammation. This mechanism offers a unique approach to addressing the underlying pathological processes of osteoarthritis rather than merely masking symptoms. Clinical evidence supports its use in improving joint function and reducing pain associated with degenerative joint disease.

- Offers alternative therapeutic option for patients with gastrointestinal intolerance to NSAIDs
- Maintains therapeutic effects after treatment discontinuation in some patients
Common use
Diacerein is primarily indicated for the symptomatic treatment of osteoarthritis, particularly affecting weight-bearing joints such as knees and hips. It is commonly prescribed for patients experiencing mild to moderate osteoarthritis where non-pharmacological measures have provided insufficient relief. The medication is often considered for long-term management in patients requiring continuous therapy, especially those who cannot tolerate conventional NSAIDs due to gastrointestinal concerns or renal issues. Medical practitioners may recommend diacerein as part of a comprehensive osteoarthritis management plan that includes physical therapy, weight management, and adjunctive analgesic therapy when necessary.
Dosage and direction
The standard adult dosage for diacerein is 50mg twice daily, taken with meals to enhance absorption and minimize potential gastrointestinal discomfort. Treatment initiation typically begins with this dosage, which may be adjusted based on individual patient response and tolerance. The full therapeutic effect usually becomes apparent after 2-4 weeks of continuous administration. For elderly patients or those with hepatic impairment, dosage reduction to 50mg once daily may be necessary. Treatment duration is generally long-term, often continuing for several months, with regular medical evaluation to assess efficacy and safety. Patients should swallow the capsules whole with adequate water and avoid crushing or chewing the medication.
Precautions
Patients with pre-existing hepatic conditions require careful monitoring of liver function tests before and during treatment. Regular assessment of renal function is advised, particularly in elderly patients or those with pre-existing renal impairment. Diacerein may cause photosensitivity reactions, necessitating sun protection measures during treatment. Patients should be monitored for gastrointestinal symptoms, as diarrhea is a commonly reported adverse effect. Those with history of inflammatory bowel disease or chronic diarrhea should use diacerein with extreme caution. Pregnancy testing should be considered in women of childbearing potential before initiating long-term therapy.
Contraindications
Diacerein is contraindicated in patients with known hypersensitivity to diacerein, rhein, or any excipients in the formulation. It must not be used during pregnancy or breastfeeding due to potential adverse effects on fetal development and infant health. Patients with severe hepatic impairment (Child-Pugh class C) should avoid diacerein therapy. Those with severe renal impairment (creatinine clearance <30 mL/min) are not candidates for this medication. The drug is contraindicated in patients with active peptic ulcer disease or inflammatory bowel conditions. Children and adolescents under 18 years of age should not use diacerein due to insufficient safety data in this population.
Possible side effect
The most frequently reported adverse reaction is diarrhea, occurring in approximately 30-40% of patients, which may range from mild to severe and sometimes necessitates treatment discontinuation. Other gastrointestinal effects include abdominal pain, dyspepsia, and nausea in 10-15% of users. Mild hepatic enzyme elevations may occur in 5-8% of patients, typically transient and asymptomatic. Skin reactions such as pruritus, rash, and photosensitivity affect approximately 3-5% of patients. Urine discoloration to yellowish-brown is a common but harmless side effect related to rhein excretion. Rare cases of severe hepatotoxicity have been reported, requiring immediate medical attention if symptoms like jaundice or dark urine appear.
Drug interaction
Diacerein may interact with anticoagulants like warfarin, potentially enhancing their effects and requiring closer monitoring of coagulation parameters. Concurrent use with other hepatotoxic medications increases the risk of liver damage and should be avoided. The absorption of diacerein may be reduced when taken with antacids or mineral supplements containing calcium, magnesium, or aluminum. Diuretic therapy may enhance the risk of renal impairment when combined with diacerein. Patients using oral hypoglycemic agents should be monitored for potential interactions affecting glucose control. The medication may theoretically interact with other interleukin-1 inhibitors, though clinical data are limited.
Missed dose
If a dose is missed, patients should take it as soon as remembered unless it is nearly time for the next scheduled dose. In that case, the missed dose should be skipped, and the regular dosing schedule resumed. Doubling the dose to make up for a missed administration is not recommended, as this may increase the risk of adverse effects, particularly gastrointestinal symptoms. Patients should maintain consistent timing of doses to ensure stable drug levels and optimal therapeutic effect. If multiple doses are missed, medical consultation is advised before resuming treatment.
Overdose
Symptoms of diacerein overdose may include severe diarrhea, abdominal cramps, nausea, and vomiting. In cases of significant overdose, hepatic toxicity manifestations such as jaundice or elevated liver enzymes might occur. There is no specific antidote for diacerein overdose. Management involves immediate gastric lavage if presentation is early after ingestion, followed by supportive care including electrolyte replacement and hydration therapy for gastrointestinal symptoms. Activated charcoal may be administered if within one hour of ingestion. Liver function should be monitored closely, and symptomatic treatment provided as needed. Patients should seek immediate medical attention in case of suspected overdose.
Storage
Diacerein capsules should be stored in their original packaging at room temperature (15-30°C), protected from light and moisture. The medication must be kept in a secure location away from children and pets. Capsules should not be transferred to other containers, as exposure to air and light may affect stability. Patients should check expiration dates before use and properly dispose of any expired medication. Storage in bathrooms or areas with high humidity should be avoided to prevent degradation of the formulation.

Diacerein is a prescription medication that should be used only under the supervision of a qualified healthcare professional. Individual response to treatment may vary, and patients should follow their physician’s instructions regarding dosage and administration.

Reviews
Clinical studies demonstrate that diacerein provides significant improvement in pain scores and functional capacity in osteoarthritis patients. Systematic reviews indicate moderate efficacy compared to placebo, with better tolerability than NSAIDs in long-term use. Patients report sustained pain relief and improved mobility after several weeks of treatment. Medical professionals appreciate its disease-modifying potential and alternative mechanism of action. Some reviews note the slow onset of action and gastrointestinal side effects as limitations. Overall, diacerein is considered a valuable option in the osteoarthritis treatment arsenal, particularly for patients requiring long-term management with gastrointestinal safety concerns.
