Usage
Rutin, a bioflavonoid, is primarily used for its antioxidant and anti-inflammatory properties. It is often used to support vascular health and treat conditions like chronic venous insufficiency (CVI) and hemorrhoids. While it has shown promise in managing conditions like osteoarthritis, high cholesterol, and high blood pressure, further research is needed to confirm its effectiveness in these areas. Rutin is classified as a bioflavonoid, also categorized as a plant pigment, vitamin P, or glycoside. Its mechanism of action involves scavenging free radicals, reducing inflammation, strengthening capillaries, and promoting collagen production.
Alternate Names
Rutin is also known as rutoside, quercetin-3-rutinoside, and sophorin. Brand names vary depending on the manufacturer and formulation.
How It Works
Pharmacodynamics: Rutin exhibits antioxidant and anti-inflammatory activities. It strengthens blood vessels, reduces capillary permeability, and inhibits platelet aggregation.
Pharmacokinetics: Limited data is available regarding the detailed pharmacokinetics of rutin. Absorption likely occurs in the gastrointestinal tract, followed by metabolism and elimination through renal and/or hepatic pathways.
Mode of Action: Rutin exerts its antioxidant effects by scavenging free radicals. Its anti-inflammatory action involves inhibiting inflammatory mediators. It binds to metal ions, inhibiting their contribution to oxidative stress. The specific receptor binding, enzyme inhibition, and neurotransmitter modulation actions of rutin are not fully elucidated yet. Elimination pathways are believed to involve both renal and hepatic mechanisms.
Dosage
Standard Dosage
Adults:
The typical dosage ranges from 500 mg to 1000 mg per day, often divided into two doses. Some studies have explored higher doses, but these should only be used under medical supervision. Oral administration is the most common route.
Children:
There is no established standard dosage for children. Rutin supplements should not be given to children without consulting a healthcare provider.
Special Cases:
- Elderly Patients: No specific dosage adjustments are consistently recommended. Monitor for any adverse effects and adjust as necessary.
- Patients with Renal Impairment: Use with caution and monitor kidney function. Dosage adjustments may be needed.
- Patients with Hepatic Dysfunction: Monitor liver function. Dose adjustments may be required.
- Patients with Comorbid Conditions: Use with caution in patients with diabetes, bleeding disorders, or those taking blood-thinning medications. Consult with a healthcare provider to assess potential risks and benefits.
Clinical Use Cases
The dosage of rutin in specific clinical scenarios like intubation, surgical procedures, mechanical ventilation, ICU use, and emergency situations is not explicitly defined in clinical guidelines. If used in these contexts, it should be under the guidance of a physician.
Dosage Adjustments
Dosage adjustments should be individualized based on patient factors such as age, weight, overall health, and the specific condition being treated. For patients with renal or hepatic impairment, careful monitoring and dosage adjustments may be necessary. Genetic polymorphisms affecting drug metabolism are not well-studied for rutin.
Side Effects
Common Side Effects:
Headache, dizziness, skin rash, dry mouth, tiredness, nausea, upset stomach, diarrhea, and constipation are common side effects. These are usually mild and transient.
Rare but Serious Side Effects:
Severe allergic reactions (rash, itching, swelling, dizziness, difficulty breathing) can occur, requiring immediate medical attention. Changes in heart rhythm are also possible.
Long-Term Effects:
Limited data exists on the long-term effects of rutin supplementation.
Adverse Drug Reactions (ADR):
Clinically significant ADRs include severe allergic reactions, changes in heart rhythm and bleeding in combination with certain medications. These require immediate medical attention.
Contraindications
Rutin is contraindicated in individuals with a known allergy to rutin or other flavonoids. Pregnant and breastfeeding women should avoid rutin supplementation due to insufficient safety data. Individuals with bleeding disorders or those taking anticoagulant or antiplatelet medications should exercise caution.
Drug Interactions
Rutin can interact with anticoagulant and antiplatelet drugs (e.g., warfarin, aspirin, clopidogrel), potentially increasing bleeding risk. It may also interact with certain anti-inflammatory drugs (NSAIDs and steroids), enhancing their effects and increasing gastrointestinal side effects. Rutin may also affect the metabolism of certain drugs processed by the liver’s cytochrome P450 enzyme system, potentially altering their effectiveness. This includes medications such as statins, some antidepressants, and antiepileptic drugs. Interactions with medications for diabetes may also occur, causing blood sugar to drop too low. Concomitant use of these medications needs careful monitoring and potential dose adjustments. Interactions with OTC drugs and supplements or food are not well documented, but general caution should be exercised.
Pregnancy and Breastfeeding
Rutin is generally considered unsafe during pregnancy and breastfeeding due to the limited available data. Pregnant women should especially avoid rutin supplementation. It is recommended to avoid use or consult a healthcare professional before use.
Drug Profile Summary

- Monitoring Parameters: Monitor for side effects, especially in patients with renal or hepatic impairment, diabetes, or those taking interacting medications.
Popular Combinations
Rutin is sometimes combined with other bioflavonoids like quercetin or with enzymes like bromelain and trypsin for osteoarthritis. However, the efficacy and safety of these combinations require further research.
Precautions
- General Precautions: Evaluate patients for allergies, bleeding disorders, current medications, and hepatic/renal function before prescribing.
- Specific Populations: Avoid use during pregnancy and breastfeeding. Use with caution in children and the elderly, monitoring for side effects.
- Lifestyle Considerations: No specific lifestyle restrictions are generally associated with rutin use. However, alcohol, smoking, and diet may affect its efficacy and side effect profile.
