Recommended Duration of Diosmin Treatment for Hemorrhoids
For hemorrhoids, diosmin treatment should be administered for 2 months, with a higher initial dose for the first 7 days followed by a maintenance dose for the remaining period. 1
Dosing Regimen
The optimal dosing schedule based on evidence is:
- First 7 days: 450 mg twice daily (900 mg/day) 1
- Subsequent period: 450 mg once daily for up to 2 months 1
Alternative dosing regimens that have been studied include:
- Acute hemorrhoid episodes: 3 tablets of MPFF 500 mg twice daily for 4 days, then 2 tablets twice daily for 3 days 2
- Chronic hemorrhoids: 2 tablets of MPFF 500 mg daily for 60-83 days 2
Efficacy Timeline
Diosmin shows a progressive improvement in hemorrhoidal symptoms:
- First week: 79% reduction in pain and 67% reduction in bleeding 1
- Second week: 98% reduction in pain and 86% reduction in bleeding 1
Clinical Application
Diosmin is appropriate for:
- First-degree and second-degree internal hemorrhoids 3
- Management of acute hemorrhoidal episodes 2, 4
- Treatment of chronic/recurrent hemorrhoids 2
- Adjunctive therapy after hemorrhoidectomy to reduce secondary bleeding 2
Mechanism of Action
Diosmin works through multiple mechanisms:
- Improves venous tone and lymphatic drainage
- Reduces capillary hyperpermeability
- Protects microcirculation from inflammatory processes 2
- Reduces venous stasis and local inflammation 4
Treatment Context
Diosmin should be used as part of a comprehensive hemorrhoid management approach:
- Conservative measures should be implemented concurrently (increased fiber intake of 25-30g daily, adequate hydration, sitz baths 2-3 times daily) 5
- For more advanced disease stages, diosmin may be used in conjunction with sclerotherapy, surgery, or compression therapy 2
Important Considerations
- Micronized purified flavonoid fraction (MPFF) containing 90% diosmin and 10% hesperidin shows improved absorption due to particle size <2 μm 2
- No conclusive evidence supports using 3000 mg/day of micronized fraction versus 1800 mg/day of purified diosmin for acute hemorrhoids 4
- Diosmin has an excellent safety profile with minimal side effects, making it suitable for first-line treatment 1
- The most common adverse events are gastrointestinal and autonomic in nature, but overall tolerability is similar to placebo 2
Treatment Decision Algorithm
For acute hemorrhoid episodes:
- Higher initial dose for 4-7 days
- Then reduced dose for maintenance
For chronic/recurrent hemorrhoids:
- Lower maintenance dose for 2 months
For post-hemorrhoidectomy:
- Begin treatment immediately after surgery
- Continue for duration recommended by surgeon
Diosmin treatment should be discontinued after the 2-month period unless symptoms persist or recur, in which case further evaluation may be necessary.
