Mesoglycan Drug Interactions, Uses, Effectiveness, Safety & More
What is this page for?
First and foremost: how Mesoglycan interacts with medications. The heart of this page is the interaction list — every drug Mesoglycan is known to interact with, and how serious each one is.
But these pages have grown well beyond that into a full monograph — what Mesoglycan is, what people use it for and how strong the evidence is, its safety and side effects, and answers to the questions we’re asked most — written and reviewed by the clinical staff at HelloPharmacist. It’s educational information from our licensed clinical databases, not medical advice, and we don’t sell or endorse products. Our editorial policy

Add one medicationMesoglycan Drug Interactions: The Bottom Line
From the HelloPharmacist Editorial Team · Updated July 2026Based on the available evidence, the overall risk of a clinically significant Mesoglycan drug interaction appears low for most people, though anyone on blood-thinning treatment deserves a closer look. None of the listed interactions are rated major, and all of them rest on the same theoretical bleeding concern rather than documented harm in people.
The interactions that matter most involve anticoagulant and antiplatelet drugs, including warfarin, aspirin, clopidogrel, heparin, and related medicines, and thrombolytic drugs used to dissolve clots. In theory, adding mesoglycan could raise bleeding risk with any of these. That said, human research suggests mesoglycan helps the body break down clots without actually changing how blood coagulates, so the concern has not been confirmed in people. Because bleeding is a narrow-margin issue, this combination is still worth monitoring rather than ignoring.
Although the list of interacting medications runs long, nearly all of those entries are individual drugs that fall into these two blood-related categories, so the list reflects one shared theoretical concern rather than many separate problems. No interaction here is rated major, and the predicted effect on clotting has not been shown to produce meaningful changes in human studies.

What Severity, Likelihood & Evidence Mean
Severity — How Serious It Can Be
- Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
- Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
- Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
- No known interaction. Checked against our sources with nothing documented — not the same as proven safety.
Likelihood — How Well It’s Documented
- Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
- Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
- Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
- Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

The kinds of drugs Mesoglycan affects
Every type of medication (drug category) Mesoglycan is known to interact with. Open any category for the detail — or search your exact drug in the checker above.
Anticoagulant/Antiplatelet Drugs
Theoretically, combined use might increase bleeding risk. However, human evidence suggests that mesoglycan has profibrinolytic activity without affecting coagulation. These agents include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.
Thrombolytic Drugs
Theoretically, combined use might increase bleeding risk. These drugs include alteplase (Activase), anistreplase (Eminase), reteplase (Retevase), streptokinase (Streptase), and urokinase (Abbokinase).
Mesoglycan: Uses, Safety & Side Effects
Mesoglycan is a blend of natural sugar-protein compounds (glycosaminoglycans, including heparan sulfate and dermatan sulfate) taken from animal tissue and used mainly for blood vessel and circulation problems. Some small studies suggest possible benefit for vein-related conditions, but the overall evidence is limited and not strong. Because it can affect blood clotting, talk to your doctor or pharmacist before using it.
- Part used
- Glycosaminoglycans extracted from porcine (pig) intestinal mucosa
- Common forms
- Tablets, capsules
- Vein health and chronic venous insufficiency
- Leg ulcers
- Peripheral artery disease and leg pain
- Reducing blood clot risk
- Hemorrhoids
Popular and traditional uses — not proof it works. See “Uses & effectiveness” below for the evidence.
Generally tolerated in studies, but it can affect blood clotting and lacks long-term safety data.

Overview
Mesoglycan is not a herb or plant. It is a natural mixture of compounds called glycosaminoglycans (GAGs), which are sugar-protein molecules that normally line the inside of blood vessels. The mesoglycan used in supplements is usually taken from the intestinal lining of pigs.
The mixture contains substances such as heparan sulfate, dermatan sulfate, and small amounts of other GAGs. These are similar to compounds found naturally in the human body that help blood flow smoothly and keep vessel walls healthy.
Mesoglycan is sold mostly in Europe as a prescription or supplement product. People most often use it for problems with veins and circulation, such as varicose veins, leg swelling, and slow-healing leg ulcers.
How it works
The glycosaminoglycans in mesoglycan are similar to natural compounds in the lining of your blood vessels. Researchers believe they may help in a few ways:
- Mild blood-thinning effect — some of the compounds are related to heparin and may make blood less likely to clot.
- Supporting vessel walls — they may help keep the inner lining of blood vessels healthy and reduce inflammation.
- Improving blood flow and breaking down clots — lab studies suggest they may support the body's natural clot-dissolving system.
Much of this understanding comes from laboratory and animal research or from how similar molecules behave in the body. The exact effects in people are not fully proven.
Does Mesoglycan work?
How to read these evidence grades
Natural Medicines’ 7-point scale. We show each rating’s label word-for-word.
Possibly Effective Cerebrovascular disease
Preliminary clinical research in small groups of patients with cerebrovascular disease shows that taking mesoglycan 96-100 mg daily orally for 6 months seems to reduce ischemic events, improve quality of life, and provide subjective improvement when compared with baseline. The validity of this finding is limited by the lack of a comparator group. There is also some preliminary evidence that mesoglycan might be comparable to standard antiplatelet drug therapy.
Possibly Effective Peripheral arterial disease (PAD)
The majority of preliminary clinical research shows that mesoglycan improves walking distance in patients with PAD, although it may not be as effective as other therapies. Alternating intravenous and oral mesoglycan seems to improve walking distance when compared with baseline in patients with intermittent claudication due to PAD. Also, injecting mesoglycan 30 mg intramuscularly for 3 weeks then taking oral mesoglycan 100 mg daily for 20 weeks appears to improve clinical response and walking distance in patients with PAD when compared with placebo. Taking mesoglycan 100 mg daily orally for a total of 120 days increases walking distance by approximately 39% when compared with baseline. However, taking oral mesoglycan 48 mg daily for 6 months is less effective at improving pain-free walking distance and total walking distance than oral defibrotide 800 mg daily in patients with intermittent claudication due to PAD.
Possibly Effective Venous leg ulcers
Clinical research shows that administering a combination of intramuscular and oral mesoglycan as an adjunct to traditional chronic venous stasis ulcer therapy improves the rate of healing when compared with traditional therapy alone. At least 75% of patients taking mesoglycan were fully healed approximately 46 days earlier than patients taking traditional therapy alone.
Possibly Ineffective Stroke
Clinical research in patients with acute ischemic stroke shows that adding intramuscular mesoglycan for 5 days, followed by 25 days of oral mesoglycan, to intravenous dexamethasone therapy is no more effective than dexamethasone alone.
Possibly Ineffective Venous thromboembolism (VTE)
Clinical research shows that taking oral mesoglycan plus compression stockings following standard deep venous thrombosis (DVT) therapy is no better than placebo for preventing recurrent DVT and/or pulmonary embolism during a follow-up period ranging from 5 to 48 months.
Also studied for 10 conditions — evidence insufficient to rate
Insufficient Reliable Evidence To Rate Atherosclerosis
Insufficient Reliable Evidence To Rate Chronic venous insufficiency (CVI)
Preliminary clinical research in adults with unilateral lower limb edema due to CVI shows that taking mesoglycan 100 mg daily for one month reduces pain and swelling by approximately 43% and 63%, respectively, when compared with placebo.
Insufficient Reliable Evidence To Rate Cutaneous necrotizing venulitis
Preliminary clinical research shows that intramuscular mesoglycan 10 mg/kg daily for 20 days might be useful for treating cutaneous necrotizing venulitis in patients with reduced fibrinolytic activity.
Insufficient Reliable Evidence To Rate Diabetic retinopathy
Preliminary clinical research in adults with diabetic retinopathy shows that taking mesoglycan 100 mg daily for 6 months reduces the occurrence of microhemorrhages, microaneurysms, and exudates, compared with no change in those taking placebo.
Insufficient Reliable Evidence To Rate Hypertension
Preliminary clinical research shows that taking mesoglycan 100 mg daily orally for a total of 120 days reduces systolic blood pressure by 5 mmHg when compared to baseline in patients with hypertension. The validity of this finding is limited by the lack of a comparator group.
Insufficient Reliable Evidence To Rate Hypertriglyceridemia
Preliminary clinical research in a small group of patients shows that taking mesoglycan 96 mg daily reduces total triglyceride and very low density lipoprotein (VLDL) levels when compared to baseline in patients with hypertriglyceridemia.The validity of this finding is limited by the lack of a comparator group.
Insufficient Reliable Evidence To Rate Metabolic syndrome
Preliminary clinical research in a small group of patients with metabolic syndrome shows that taking mesoglycan 50 mg twice daily for 90 days improves vascular function, as measured by brachial flow-mediated dilation and arterial stiffness, when compared with placebo.
Insufficient Reliable Evidence To Rate Postoperative pain
Preliminary, prospective clinical research in a small group of patients undergoing open excisional diathermy hemorrhoidectomy shows that intramuscular mesoglycan (Prisma, Mediolanum Farmaceutici) 60 mg daily for 5 days postoperatively, then 50 mg orally twice daily for 30 days, reduces pain after rectal examination, but not spontaneous pain or pain after defecation, and shortens the time to full resumption of normal daily activities, when compared with ketorolac 10 mg orally every 4-6 hours for 5 days. A retrospective, observational study in a larger group of patients undergoing the same surgery shows that giving the same mesoglycan regimen in conjunction with the ketorolac regimen reduces pain on postoperative day 1 and after 1, 3, and 6 weeks of follow-up when compared with the ketorolac regimen alone. The addition of mesoglycan also reduces the incidence of postoperative rectal thromboses and the time to recovery of normal activities, but does not reduce postoperative bleeding or time to wound healing, when compared with ketorolac alone.
Insufficient Reliable Evidence To Rate Tinnitus
Observational research in patients with tinnitus has found that taking mesoglycan 50 mg daily for 90 days is associated with an improvement in tinnitus when compared to baseline. The validity of this finding is limited by the lack of a comparator group .
Insufficient Reliable Evidence To Rate Vertigo
Observational research in patients with vertigo has found that taking mesoglycan 50 mg daily for 90 days is associated with an improvement in vertigo symptoms when compared to baseline. The validity of this finding is limited by the lack of a comparator group.

Where Natural Medicines hasn’t rated a use, HelloPharmacist’s pharmacists may add their own reviewed rating and evidence (each such entry is labeled). This is educational information, not medical advice — talk with your pharmacist or doctor before starting, stopping, or changing a supplement.
Safety & precautions
In the studies done so far, mesoglycan has generally been tolerated fairly well. However, long-term safety data are limited, and it is not a well-known product in many countries.
Because mesoglycan can affect blood clotting, use extra caution if you have a bleeding disorder, are scheduled for surgery, or take medicines or supplements that thin the blood. Stop use and tell your surgeon before any planned procedure.
People with allergies to animal-derived products should be aware that mesoglycan typically comes from pig tissue.
Pregnancy and breastfeeding: There is not enough information to know if mesoglycan is safe during pregnancy or while breastfeeding. To be safe, avoid it during these times unless your doctor specifically advises otherwise.
Always check with your pharmacist or doctor before starting mesoglycan, especially if you have a health condition or take other medicines.
Side effects
Reported side effects are usually mild and may include:
- Stomach upset, nausea, or heartburn
- Mild diarrhea or other digestive complaints
Because mesoglycan is related to blood-thinning compounds, there is a possible risk of easy bruising or bleeding, though this is not common at typical doses. Allergic reactions are possible, especially in people sensitive to animal products. Seek medical help right away for signs of a serious allergic reaction such as swelling, trouble breathing, or unusual bleeding.
Mesoglycan: Reported Adverse Effects
Documented safety reports on Mesoglycan from the evidence-graded Natural Medicines (TRC Healthcare) database, shown word-for-word from the licensed record.
Orally, mesoglycan seems to be well tolerated. Some adverse effects reported in clinical studies include nausea, vomiting, epigastric pain, dyspepsia, heartburn, headache, diarrhea, and local cutaneous reactions.
However, there is some concern about potential contamination. Mesoglycan is derived from raw animal tissues gathered from slaughterhouses, possibly from sick or diseased animals. Products made from contaminated or diseased organs might present a human health hazard. There is also concern that mesoglycan produced from cows in countries where bovine spongiform encephalitis (BSE) has been reported might be unsafe. However, there are no reports of disease transfer to humans from contaminated mesoglycan.

Dosing
There is no official, standardized dose of mesoglycan, and products can differ from one another. In studies it has been given by mouth in divided daily doses, and sometimes by injection in medical settings.
If you use a mesoglycan product, follow the directions on the label and do not exceed the recommended amount. Because the right dose for any given person is not well established, it is best to check with your pharmacist or doctor first to make sure it is appropriate for you.
