Background
Diosmin might work by reducing swelling and restoring normal vein function. Diosmin also seems to have antioxidant effects. Diosmin is often taken with other plant flavonoids like hesperidin.
Diosmin is most often used for hemorrhoids and poor blood flow. It's also used for back pain and many other conditions, but there's no strong scientific evidence to support most of these uses.
Safety Safety definitions
Special Precautions & Warnings:
Pregnancy and breast-feeding: Diosmin is commonly consumed from citrus fruits. Diosmin supplements are possibly safe to take with other flavonoids like hesperidin when pregnant or breast-feeding.Surgery: Diosmin might prolong bleeding and might increase the risk of bleeding during and after surgical procedures. Stop taking diosmin at least 2 weeks before a scheduled surgery.
Effectiveness
- Poor circulation that can cause the legs to swell (chronic venous insufficiency or CVI). Taking diosmin by mouth with other flavonoids like hesperidin might help reduce pain by a small amount in people with CVI. It's not clear if taking diosmin alone helps.
- Hemorrhoids. Taking diosmin by mouth with other flavonoids like hesperidin seems to reduce symptoms of hemorrhoids and might also help to keep hemorrhoids from coming back.
- Leg sore caused by weak blood circulation (venous leg ulcer). Taking diosmin by mouth with other flavonoids like hesperidin while using compression dressings seems to help heal leg ulcers caused by poor circulation.
Dosing & administration
Interactions with pharmaceuticals
Carbamazepine (Tegretol)
Interaction Rating=Moderate Be cautious with this combination.
Diosmin might decrease how quickly the body breaks down carbamazepine. Taking diosmin along with carbamazepine might increase the effects and side effects of carbamazepine.
Chlorzoxazone (Parafon Forte, Paraflex)
Interaction Rating=Moderate Be cautious with this combination.
Diosmin might decrease how quickly the body breaks down chlorzoxazone. Taking diosmin along with chlorzoxazone might increase the effects and side effects of chlorzoxazone.
Diclofenac (Voltaren, others)
Interaction Rating=Moderate Be cautious with this combination.

Fexofenadine (Allegra)
Interaction Rating=Moderate Be cautious with this combination.
Some medications, such as fexofenadine, are moved by pumps in cells. Diosmin might affect these pumps and increase how much of some medications get absorbed by the body. This might cause more side effects from some medications, like fexofenadine.
Medications changed by the liver (Cytochrome P450 2C9 (CYP2C9) substrates)
Interaction Rating=Moderate Be cautious with this combination.
Some medications are changed and broken down by the liver. Diosmin might change how quickly the liver breaks down these medications. This could change the effects and side effects of these medications.
Medications changed by the liver (Cytochrome P450 2E1 (CYP2E1) substrates)
Interaction Rating=Moderate Be cautious with this combination.
Some medications are changed and broken down by the liver. Diosmin might change how quickly the liver breaks down these medications. This could change the effects and side effects of these medications.
Medications changed by the liver (Cytochrome P450 3A4 (CYP3A4) substrates)
Interaction Rating=Moderate Be cautious with this combination.
Some medications are changed and broken down by the liver. Diosmin might change how quickly the liver breaks down these medications. This could change the effects and side effects of these medications.
Medications moved by pumps in cells (P-Glycoprotein Substrates)
Interaction Rating=Moderate Be cautious with this combination.
Some medications are moved in and out of cells by pumps. Diosmin might change how these pumps work and change how much medication stays in the body. In some cases, this might change the effects and side effects of a medication..
