Can I take Candesartan and Collagen together?

Why this happens

Candesartan is a blood pressure medication (an angiotensin II receptor blocker) that works on the hormonal system controlling blood vessels. Collagen is a protein supplement used for skin, joint, and bone health. These two substances are processed by the body through different pathways and do not interfere with how the other works.

What you should do

You can continue taking both as prescribed or directed. As with any supplement, it is always a good idea to inform your GP or pharmacist about everything you are taking to ensure your medical records are up to date.

Important precautions

Pregnancy

You must not take candesartan if you are pregnant. It can cause serious harm or death to an unborn baby, especially if taken during the second and third trimesters.

Severe allergies (Anaphylaxis)

Check the source of the collagen (e.g., bovine, marine, or porcine). Do not take this if you have a known allergy to the source animal, as it can trigger a severe allergic reaction.

Food and drink warnings

Alcohol

Drinking alcohol while taking candesartan can increase the blood-pressure-lowering effect of the medicine. This may make you feel dizzy, lightheaded, or faint, especially when standing up. It is best to keep your alcohol intake within recommended limits and see how the medicine affects you before drinking.

Potassium-rich foods (e.g., bananas, spinach, salt substitutes)

Candesartan can increase the levels of potassium in your blood. Consuming large amounts of foods very high in potassium or using potassium-based salt substitutes (such as Lo-Salt) can lead to dangerously high potassium levels (hyperkalaemia). You should avoid using potassium-based salt substitutes unless advised otherwise by your doctor.
