Diosmin is a naturally occurring flavonoid compound primarily derived from citrus fruits like lemons or oranges. It belongs to a class of plant-based compounds known as bioflavonoids, known for their antioxidant and anti-inflammatory properties. Chemically, diosmin is a glycosylated form of the flavonoid diosmetin, meaning it has a sugar molecule attached to its structure.
Diosmin is primarily used to treat various vascular conditions, with its most prominent applications being in managing haemorrhoids and chronic venous insufficiency (CVI).
Diosmin is commercially available as a dietary and often combined with hesperidin, another citrus-derived bioflavonoid. This combination is called Micronised Purified Flavonoid Fraction (MPFF).
It is advisable to take diosmin supplements with food, as directed by the manufacturer or a doctor. The duration of supplementation may vary based on the condition and the person's response to treatment.
Diosmin is generally well-tolerated when taken at recommended doses. However, some diosmin side effects have been reported, though they are typically mild and infrequent. The most common side effects associated with diosmin include:
Diosmin is a vasoactive drug that supports circulatory health through various actions on blood vessels. It enhances lymphatic drainage and improves microcirculation while increasing venous tone and elasticity. These properties make diosmin a frequently used supplement for individuals with chronic venous disease to support vascular health, as it has been demonstrated to improve quality of life.
Diosmin may interact with various medications, thus altering their effectiveness and increasing their risk of adverse effects. Before starting diosmin, it is essential to inform your doctor about all the ongoing medicines and supplements.
Diosmin is generally recognised as a safe over-the-counter supplement when taken at recommended doses. However, some side effects have been reported, though they are typically mild and infrequent. The most common adverse effects of diosmin tablets are stomach pain, diarrhoea, headaches, dizziness, skin rash, hives, muscle pain, and – in severe cases – an irregular heartbeat.
Diosmin is commercially available as a nonprescription dietary supplement. It is most often combined in a micronised form with hesperidin (diosmin 90% plus hesperidin 10%), referred to as micronised purified flavonoid fraction (MPFF).
Diosmin may interact with certain medications metabolised by the liver, potentially altering their effectiveness or increasing the risk of adverse effects. It may inhibit various liver enzymes responsible for metabolising medications, such as anticonvulsants, antihistamines, muscle relaxants, non-steroidal anti-inflammatory drugs (NSAIDs), and acetaminophen.
Numerous studies have demonstrated the efficacy of diosmin in treating various conditions, particularly haemorrhoids and chronic venous insufficiency (CVI). It has been shown to alleviate symptoms associated with haemorrhoids, such as itchiness, bleeding, discharge, and discomfort, and can reduce recovery time following a hemorrhoidectomy.
Additionally, diosmin has been found to improve symptoms of CVI, including leg ulcers, oedema, varicose veins, tingling sensations, and subjective pain ratings, while enhancing the overall quality of life.
If you forget to take your dose at your usual time, take it as soon as you remember. If it's almost time for your next dose, skip that dose, then take the next dose as usual the next day. Do not take two doses on the same day.
While diosmin is generally considered safe when taken at recommended doses, some studies have suggested that it may have protective effects on kidney function. However, if you have any underlying kidney conditions, it is essential to consult with a doctor before taking diosmin to ensure its safety and appropriateness for your condition.
Diosmin is not recommended for use in certain groups due to a lack of safety research:
Diosmin may slow blood clotting, and taking it with anticoagulants might increase the chances of bruising and bleeding. It may also interact with certain herbal supplements involved in blood thinning, such as fenugreek, feverfew, garlic, ginger, ginkgo, ginseng, and turmeric. If you have a bleeding disorder or are taking any blood-thinning medications or supplements, consult with your doctor before trying diosmin.
It is generally recommended that diosmin supplements be taken with food, as directed by the manufacturer or a doctor. Taking diosmin with meals may improve absorption and reduce the chance of potential side effects, such as stomach discomfort or irritation.
