Who is this for?
Diosmin is a natural plant-based medicine made from citrus fruits that strengthens your blood vessels and improves blood flow, especially in the veins of your legs and around your anus.
Enhances venous tone and reduces capillary fragility by inhibiting phosphodiesterase and increasing cAMP levels in vascular smooth muscle, while decreasing inflammatory mediator release and reducing vascular permeability through antioxidant mechanisms.

If you miss a dose, take it as soon as you remember. But if it is almost time for your next dose, just skip the missed one and continue as normal. Do not take double to catch up.
Buy only from licensed pharmacies, and avoid buying from roadside sellers or open markets where the drug may be expired or fake. If your pile symptoms do not improve after 2 weeks of use, see a doctor as it may need further treatment. Do not use diosmin as a substitute for seeing a doctor if you notice blood in your stool.
Diosmin may interact with blood-thinning drugs like warfarin and increase bleeding risk, so tell your doctor if you take any blood thinner. It may also affect how your body handles certain drugs processed by the liver. There is no major alcohol interaction, but it is best to reduce alcohol if you have pile or vein problems since alcohol makes them worse.
Check your specific combination
Is it safe to take Diosmin with your other drugs?
Consult your doctor before taking diosmin if you are pregnant or breastfeeding. While studies have not shown major harm, it is best to get your doctor's approval first.
