Why this happens
Candesartan is a blood pressure medication (angiotensin II receptor blocker) that is processed by the liver and kidneys. Chondroitin is a supplement used for joint health. These two substances do not share the same metabolic pathways and do not have opposing or overlapping effects on the body.
What you should do
Back to contentsYou can continue taking both as prescribed. However, always inform your doctor or pharmacist about any new supplements you start, and monitor your blood pressure regularly as part of your routine care.

Important precautions
Back to contentsPregnancy
You must not take candesartan if you are pregnant. It can cause serious harm or death to an unborn baby, especially if used during the second and third trimesters. Use effective contraception and stop taking it immediately if you think you are pregnant.
High potassium levels (Hyperkalaemia)
Candesartan can significantly increase potassium levels in your blood. Avoid using potassium supplements or salt substitutes containing potassium unless specifically advised by your doctor.
Warfarin treatment (Blood thinning)
Chondroitin may increase the blood-thinning effect of warfarin, which can lead to a higher risk of serious bleeding. Do not start this supplement without your doctor monitoring your INR levels.
Food and drink warnings
Back to contentsAlcohol
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.
Salt substitutes (Potassium-rich)
Candesartan can increase the levels of potassium in your blood. Many salt substitutes (such as Lo-Salt) contain potassium chloride instead of sodium. Using these while taking candesartan can lead to dangerously high potassium levels (hyperkalaemia). You should avoid using potassium-based salt substitutes unless advised otherwise by your doctor.

Patient picks for Drug interactions

Treatment and medication
Can I take Alcohol and Candesartan together?
Drinking alcohol while taking candesartan can cause your blood pressure to drop too low. This can make you feel dizzy, lightheaded, or faint, especially when you stand up quickly from a sitting or lying position. You might also experience a headache or a fast heartbeat.

Treatment and medication
Can I take Levothyroxine and Fibre supplements together?
Taking fibre supplements at the same time as levothyroxine can stop your body from absorbing the medicine properly. This means you might not get the full dose of thyroid hormone you need, which could lead to symptoms of an underactive thyroid, such as feeling tired, cold, or gaining weight.
