Written by Medicover Team and Medically Reviewed by Dr Manoj Kumar D, General Surgery
Diosmin is a plant-derived compound commonly found in citrus fruits such as oranges and lemons. It is widely used as a dietary supplement to support blood vessel and circulatory health. Diosmin is often combined with another natural flavonoid, hesperidin, for enhanced therapeutic effect.
Diosmin is a natural flavonoid glycoside belonging to the flavone class of compounds, with the molecular formula C28H32O15. It is known for its vasoprotective properties and is used to manage conditions like chronic venous insufficiency, varicose veins, and hemorrhoids. Available mainly in tablet or capsule form, it works by improving vein tone, reducing inflammation, and enhancing lymphatic drainage.
Diosmin is primarily used to improve blood circulation and strengthen blood vessel walls, which helps alleviate symptoms associated with various venous disorders.
Diosmin is used to treat a range of conditions, including:
Beyond its primary uses, Diosmin is also utilized to treat swelling of the arms (lymphedema) and to offer protection against liver toxicity, particularly after breast cancer surgery.
Diosmin primarily functions by enhancing the tone and strength of blood vessels, especially veins, and by improving overall blood circulation. Additionally, it acts as an antioxidant, contributing to its therapeutic effects.
Diosmin dosage varies depending on the condition being treated, and it is crucial to follow a doctor's advice for proper administration.
For acute hemorrhoid attacks, the typical dosage is:
Each tablet usually contains Diosmin 450 mg + Hesperidin 50 mg.
Always follow your doctor's instructions for exact dosage.
If you miss a dose of Diosmin, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.
While there are no known cases of diosmin overdose or reports of toxicity to date, an overdose might lead to increased gastrointestinal discomfort, headache, or general malaise. If you suspect an overdose or experience severe symptoms, it is crucial to stop taking the medication and consult your doctor immediately.
Symptoms of a potential overdose may include severe gastrointestinal upset, headache, and unusual bleeding.
Avoid taking more than the recommended dose unless instructed to do so by your healthcare provider. If you experience severe pain, severe diarrhea (10 or more loose stools in 24 hours), or an irregular heartbeat, seek medical attention immediately.
