There is no known significant interaction between ramipril and a standard Vitamin B complex supplement. It is generally considered safe to take these together.
Why this happens
Ramipril is an ACE inhibitor used for blood pressure, while Vitamin B complex contains water-soluble vitamins (such as B1, B2, B6, B12, and folic acid). These substances are processed by the body through different pathways and do not interfere with each other's absorption, metabolism, or effectiveness.
What you should do
You can continue taking both as prescribed or recommended. As with any supplement, it is best to take them at the same time each day to maintain a routine. If you experience any new or unusual symptoms, such as feeling dizzy or lightheaded, consult your pharmacist or GP.
Important precautions
Pregnancy
Do not take ramipril if you are pregnant or planning to become pregnant, as it can cause serious harm or death to an unborn baby.
Angioedema (Severe swelling)
Ramipril can cause a rare but serious allergic reaction involving sudden swelling of the face, lips, tongue, or throat (angioedema). If this occurs, stop taking the medicine and seek emergency medical help immediately. This risk is higher in people of African or Caribbean descent.
Food and drink warnings
Alcohol
It is best to avoid or strictly limit alcohol while taking ramipril. Alcohol can increase the blood pressure-lowering effect of ramipril, which may make you feel dizzy, lightheaded, or faint, especially when you first start the medicine or move to a higher dose.
It is best to avoid or strictly limit alcohol when taking Vitamin B complex. Alcohol interferes with the absorption of B vitamins (especially B1 and B12) and increases their excretion from the body, making the supplement less effective. Additionally, chronic alcohol use can lead to severe B vitamin deficiencies.
Salt substitutes and high-potassium foods
Ramipril can increase the levels of potassium in your blood. You should avoid using salt substitutes that contain potassium (such as Lo-Salt) and speak to your doctor before significantly increasing your intake of high-potassium foods like bananas, spinach, or pulses. High potassium levels can affect your heart rhythm.

Patient picks for Drug interactions

Can I take Warfarin and Aspirin together?
Taking warfarin and aspirin together significantly increases your risk of serious bleeding. This includes internal bleeding, such as in the stomach or brain, as well as bleeding that is hard to stop from minor cuts or injuries.

Can I take Magnesium and Wegovy flextouch together?
There is no known direct interaction between magnesium supplements and Wegovy (semaglutide). However, both can affect your digestive system. Wegovy slows down how quickly your stomach empties, which could theoretically change how quickly your body absorbs magnesium, though this is rarely a clinical concern. Additionally, both can cause side effects like nausea or changes in bowel habits (magnesium often softens stools, while Wegovy can cause constipation or diarrhoea).
