Diacerein is a disease-modifying osteoarthritis drug (DMOAD) specifically formulated for the symptomatic and structural management of osteoarthritis. Unlike conventional analgesics, which primarily mask pain, diacerein works by inhibiting interleukin-1 beta, a key pro-inflammatory cytokine implicated in cartilage degradation. This mechanism offers a unique approach to managing osteoarthritis progression, providing both relief from discomfort and potential long-term joint preservation. It is particularly indicated for osteoarthritis of the hip and knee, offering a therapeutic option for patients seeking to address the underlying disease process.
Features
- Active Pharmaceutical Ingredient: Diacerein 50 mg.
- Pharmacological Class: Interleukin-1 inhibitor.
- Formulation: Typically available in capsule or tablet form for oral administration.
- Mechanism of Action: Specifically inhibits the activity of interleukin-1 beta, a primary cytokine driver of inflammation and cartilage breakdown in osteoarthritis.
- Onset of Action: Exhibits a delayed onset; therapeutic benefits are typically observed after 2-4 weeks of continuous treatment.
- Prescription Status: Available by prescription in most jurisdictions.
Benefits
- Provides symptomatic relief from osteoarthritis pain and improves joint function and mobility.
- Offers a disease-modifying effect by potentially slowing the progression of cartilage degradation.
- Reduces joint stiffness, enhancing quality of life and daily activity performance.
- Possesses a favorable safety profile for long-term use compared to chronic NSAID therapy.
- May delay or reduce the need for more invasive interventions, such as joint replacement surgery.
- Functions as a non-opioid, non-NSAID analgesic alternative, mitigating risks associated with those drug classes.
Common use
Diacerein is primarily indicated for the symptomatic treatment of osteoarthritis, most commonly affecting large weight-bearing joints like the hips and knees. It is used in adults to reduce pain, decrease stiffness, and improve physical function. Its disease-modifying properties make it a suitable choice for patients in the early to moderate stages of osteoarthritis who are looking for a treatment that addresses the underlying pathophysiology of the condition, not just the symptoms.
Dosage and direction
The standard recommended adult dosage is 50 mg (one capsule/tablet) taken twice daily, typically with meals to improve gastrointestinal tolerance. Treatment should be initiated under the supervision of a physician. A lower initial dose may sometimes be recommended. The full therapeutic effect is not immediate and is usually evident after several weeks of continuous administration. The duration of treatment is long-term and should be periodically re-evaluated by a healthcare professional based on therapeutic response and tolerability. Do not crush or chew the capsules/tablets; swallow them whole with a full glass of water.
Precautions
- Use with caution in patients with known gastrointestinal disorders, as diacerein can cause soft stools or diarrhea.
- Liver function should be monitored periodically during long-term therapy, although hepatotoxicity is rare.
- Safety and efficacy in children and adolescents under 18 years of age have not been established.
- Elderly patients do not typically require a dosage adjustment, but may be more susceptible to side effects, necessitating closer monitoring.
- Patients should inform their doctor of all other medications they are taking to avoid potential interactions.
- It is not recommended for use during pregnancy or breastfeeding unless clearly necessary and directed by a physician.
Contraindications
- Known hypersensitivity to diacerein, anthraquinones, or any of the excipients in the formulation.
- Patients with a history of severe or chronic diarrhea, inflammatory bowel disease (e.g., Crohn’s disease, ulcerative colitis), or other significant intestinal disorders.
- Severe hepatic impairment or active liver disease.
- Severe renal impairment (creatinine clearance < 30 mL/min).
Possible side effect
The most frequently reported side effect is a change in bowel habits, particularly soft stools or diarrhea, which often diminishes with continued treatment. Other less common side effects may include:
- Abdominal pain or discomfort
- Nausea
- Epigastric pain
- Mild and transient skin reactions (e.g., rash, pruritus)
- Urine discoloration (a harmless yellow-orange coloration)
- In rare cases, elevated liver enzymes
Drug interaction
Formal interaction studies are limited. However, potential interactions should be considered with:
- Laxatives or other drugs that accelerate gastrointestinal transit: May exacerbate diarrhea.
- Other hepatotoxic drugs: May potentially increase the risk of liver injury, though the risk with diacerein is low. Concurrent use requires careful monitoring.
- Antacids: The effect on diacerein absorption is not fully established, but separating administration by a few hours is often advised.
Missed dose
If a dose is missed, it should be taken as soon as remembered. However, if it is almost time for the next scheduled dose, the missed dose should be skipped. Do not take a double dose to make up for a missed one. Maintaining a regular dosing schedule is important for optimal efficacy.
Overdose
There is limited data on acute overdose with diacerein. Based on its pharmacological profile, symptoms of overdose would likely be an exacerbation of its known adverse effects, primarily severe diarrhea and possibly abdominal cramps. There is no known specific antidote. Treatment should be supportive and symptomatic, including maintaining hydration and electrolyte balance. Gastric lavage may be considered if ingestion was very recent. In case of suspected overdose, immediate medical attention should be sought.
Storage
Store at room temperature (15°C - 25°C or 59°F - 77°F) in a dry place, protected from light and moisture. Keep the container tightly closed. Keep out of reach of children and pets. Do not use the medicine after the expiration date printed on the packaging.

Reviews
“After six months on diacerein for my knee OA, the constant background ache has significantly reduced. The initial GI side effects subsided after a few weeks. I feel it’s doing more than just pain relief.” – Patient, 62 “As a rheumatologist, I find diacerein to be a valuable tool, particularly for patients who are not optimal candidates for long-term NSAIDs. Its delayed onset requires patient education, but the long-term benefits for joint health can be substantial.” – Dr. A. Sharma, MD “It took nearly a month to feel a difference, but the improvement in my morning stiffness has been remarkable. It’s reassuring to be on a treatment that targets the disease process itself.” – Patient, 58
