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.

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.

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.

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.
