No Known Interaction
The bottom line No known interaction

We found no known interaction between Mediterranean Diet and Alvimopan in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist.

Mediterranean Diet and Alvimopan

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Alvimopan and Mediterranean Diet in our sources. This does not guarantee that the combination is completely free of risk — research on Mediterranean Diet alongside specific medications may be limited.

Worth understanding: our licensed dataset holds no drug-interaction record for Mediterranean Diet at all — not against Alvimopan, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

Mediterranean Diet is an eating pattern rather than something you take. Ask your pharmacist or doctor before changing how you eat while on a prescribed medicine: some medicines are dosed around meals, and a change in diet can change how they work. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What to actually watch for

What Alvimopan’s Own FDA Label Lists

This is not an interaction — none of it involves Mediterranean Diet. These are the most notable effects listed in the ADVERSE REACTIONS section of Alvimopan’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you follow Mediterranean Diet and take the medicine. One of them is worth acting on rather than waiting out — marked below.

  • A heart attack Worth acting on mentioned in 9.3% of FDA reports for Alvimopan
  • Stomach upset

From the ADVERSE REACTIONS section of the FDA label for Alvimopan. Read the label on DailyMed › Where a percentage is shown, it is the share of 43 voluntary FDA FAERS reports for Alvimopan that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Mediterranean Diet’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Mediterranean Diet side to compare — that is a limit of the record, not a statement that Mediterranean Diet has no side effects.

About Mediterranean Diet

What is Mediterranean Diet?

  • Heart health
  • Weight management
  • Type 2 diabetes prevention
  • Brain and memory health
  • Reducing inflammation
  • General longevity

The Mediterranean diet is an eating pattern rich in vegetables, fruits, whole grains, legumes, nuts, fish, and olive oil, with limited red meat and processed foods. It has some of the strongest evidence of any diet for supporting heart health and is widely considered safe for most people. Talk to your doctor or a dietitian before making big changes, especially if you have a medical condition.

Whole-food eating pattern (not a pill or supplement)

An interaction check asks whether these two react with each other — it does not ask whether Mediterranean Diet is a good idea for someone in your situation. Here is what our Mediterranean Diet record says about it on its own.

Mediterranean Diet: dosing

There is no pill or fixed "dose" for the Mediterranean diet—it is an overall pattern. The general approach is to make vegetables, fruits, whole grains, beans, and olive oil the base of most meals, eat fish a couple of times per week, choose nuts and seeds for snacks, and limit red meat, processed foods, and sweets.A registered dietitian can help you tailor the pattern to your calorie needs, health conditions, and food preferences.

About Alvimopan

What Is Alvimopan Used For?

Brand name: Entereg

Alvimopan capsules are used in hospitals to help the digestive tract recover more quickly after surgery that involves removing part of the bowel (partial bowel resection with primary anastomosis — meaning the remaining ends are reconnected). After this type of surgery, the bowel often temporarily stops working, a condition called postoperative ileus.

This medication is only given during a short hospital stay and is not for long-term or home use.

Most-Reported Side Effects for Alvimopan

From FAERS, the FDA’s public side-effect reporting system (43 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Hospitalisation 19 reports
Acute kidney injury 5 reports
Acute myocardial infarction 4 reports
Ileus 3 reports
Pruritus 3 reports
