Candesartan – Quick Guide for UK Patients

If you’ve been prescribed Candesartan, you probably want to know what it does, how to take it, and whether it’s safe. In simple terms, Candesartan belongs to a group called ARBs (angiotensin‑II receptor blockers) and helps relax your blood vessels so the heart doesn’t have to work so hard. Below you’ll find the most useful facts you need to keep your blood pressure under control without any guesswork.

How Candesartan Lowers Blood Pressure

When the hormone angiotensin‑II tightens blood vessels, your blood pressure shoots up. Candesartan blocks the receptors that angiotensin‑II binds to, which stops that tightening effect. The result is wider vessels, lower resistance, and a drop in systolic and diastolic numbers. Most UK doctors start patients on a low dose and check the reading after a week or two, adjusting as needed.

The drug works best when you pair it with lifestyle changes – cutting back on salty foods, regular walks, and keeping a healthy weight. The NHS recommends checking your blood pressure at home at least twice a week while you’re getting used to the medication.

Dosage, Side Effects & Safe Use

Typical adult doses in the UK start at 4 mg once daily, with a usual maintenance range of 8–32 mg. You can take Candesartan with or without food, but try to take it at the same time each day to keep levels steady. If you miss a dose, take it as soon as you remember unless it’s almost time for the next one – then just skip the missed pill.

Common side effects are mild: headache, dizziness, or a tired feeling. These usually fade after the first week. If you notice a sudden drop in blood pressure, especially when standing up, let your GP know – they may lower the dose. Rare but serious reactions include swelling of the face or lips and severe rash; seek urgent care if those appear.

Drug interactions matter. Candesartan can raise potassium levels, so avoid taking it with potassium‑rich salt substitutes or supplements unless your doctor says it’s okay. NSAIDs like ibuprofen may blunt the blood‑pressure‑lowering effect, so use them sparingly. If you’re on a diuretic, your doctor will likely monitor kidney function and electrolytes more closely.

Pregnancy is a no‑go. ARBs can harm the unborn baby, so stop Candesartan as soon as you find out you’re pregnant and talk to your GP about alternatives. Breast‑feeding women should also discuss safety with a healthcare professional.

Regular check‑ups are key. The NHS usually asks for blood tests after the first month and then every six months to ensure kidneys and potassium are normal. Keep a list of all medicines, including over‑the‑counter products, and bring it to every appointment.

Overall, Candesartan is a reliable option for many people with high blood pressure, especially if ACE inhibitors gave you a cough. By following the dosing schedule, watching for side effects, and staying in touch with your GP, you can keep your numbers in a healthy range and reduce the risk of heart attacks or strokes.
