What Cardenol is and what it is used for
Cardenol is an antihypertensive medicine. It is used to treat hypertension by relaxing the blood vessels so that blood flows through them more easily, which lowers blood pressure. It may also be used as prophylaxis against certain types of chest pain.
Before you take Cardenol
Tell your doctor about all your medical conditions. A known contraindication to this medicine is severe low blood pressure or a previous allergic reaction to any calcium channel blocker. Caution is advised if you have reduced renal function, as your kidneys clear part of the medicine.
How to take it
Your doctor will usually start you on a low dose and titrate it upward over several weeks, adjusting the amount until your blood pressure is controlled. Take one tablet at the same time each day. Do not stop suddenly without medical advice.
Other medicines and Cardenol
- Taking an NSAID such as ibuprofen for pain may reduce how well Cardenol lowers your blood pressure.
- Some medicines affecting the liver or renal system can change how much Cardenol stays in your body.
Possible side effects
Like all medicines, Cardenol can cause side effects. A common adverse reaction is mild ankle swelling, headache, or flushing. Gastrointestinal effects such as nausea or stomach discomfort may also occur. Seek urgent help if you experience a severe allergic reaction.
