Pharmacist Analysis

Fenugreek is generally considered relatively safe in regard to potential drug interactions.

Nevertheless, interactions are possible between fenugreek and:

  • 'Blood-thinning' drugs
  • Drugs that lower blood pressure
  • Drugs that low blood sugar

Fenugreek contains some components that can prevent blood from clotting. However, there is not enough research to confirm whether the amount of these components present in common fenugreek products can have a clinically significant effect.

Fenugreek may also have an additive effect with blood sugar-lowering medication and blood pressure-lowering medication.

All of these potential interactions are documented individually on our specific drug-herbal interaction pages.

Fenugreek Overview

Fenugreek Fenugreek (Trigonella foenum-graecum) is a plant native to the Mediterranean region and western Asia. The seeds have a nutty, slightly bitter taste and are commonly used in different types of cuisine. The leaves, which are known as "methi," are used in cooking as well. In addition to its use as a spice and herb, fenugreek has a long history of use in traditional medicine. Some studies have suggested that fenugreek may have potential health benefits, including the ability to lower blood sugar levels in people with diabetes, improve cholesterol levels, and reduce inflammation. It may also have potential benefits for women who are breastfeeding, as it is thought to increase milk production and improve the quality of breast milk.

Nitroglycerin Overview

  • Nitroglycerin ointment (Nitro-Bid) is used to prevent episodes of angina (chest pain) in people who have coronary artery disease (narrowing of the blood vessels that supply blood to the heart). Nitroglycerin ointment can only be used to prevent attacks of angina; it cannot be used to treat an attack of angina once it has begun. Nitroglycerin ointment (Rectiv) is used in adults to treat pain from anal fissures (a split or tear in the tissue near the rectal area). Nitroglycerin is in a class of medications called vasodilators. Nitroglycerin ointment prevents angina by relaxing the blood vessels so that the heart does not need to work as hard and therefore does not need as much oxygen. Nitroglycerin ointment treats anal fissure pain by relaxing the blood vessels, which reduces the pressure in the anal tissues.
