There is no known direct interaction between ramipril and vitamin D supplements. It is generally considered safe to take these two together.
Why this happens
Ramipril is an ACE inhibitor used for blood pressure, and Vitamin D is a fat-soluble vitamin. They are processed by different pathways in the body and do not interfere with each other's effectiveness or safety.
What you should do
You can continue taking both as prescribed. However, always ensure your doctor monitors your kidney function and potassium levels regularly, as ramipril can sometimes affect these, regardless of vitamin D intake.
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.
Hypercalcaemia (high blood calcium)
Do not take vitamin D if you have high levels of calcium in your blood or urine, as it can lead to serious kidney damage and heart rhythm problems.
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.
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.
High-fat meals
Vitamin D is a fat-soluble vitamin. It is best absorbed by your body when taken with a meal that contains some fat (such as eggs, avocado, nuts, or dairy).

Can I take Guanfacine and Tizanidine together?
Taking these two medicines together can cause your blood pressure to drop too low and make you feel very sleepy or dizzy. You may feel faint, lightheaded, or even pass out, especially when standing up quickly. It can also significantly slow your heart rate.

Can I take Iron supplements and Sedoxil together?
Taking iron supplements at the same time as Sedoxil (mexazolam) may reduce how much of the medication your body absorbs. This could make the Sedoxil less effective at treating anxiety or helping you sleep.
