Product introduction

Caredin 20mg Tablet may be prescribed alone or along with other medicines. Your doctor will decide the dose and duration of the treatment. Your doctor may adjust the dose depending on how you respond to this medicine and your blood pressure levels. You can take it at any time of the day, with or without food, but it is best to take it at the same time each day.

Keep taking it for as long as advised by your doctor. Even if you feel well, do not stop this medicine on your own because high blood pressure often has no symptoms. If you stop taking it, your condition may get worse. Maintaining an active lifestyle through regular exercise, managing your weight, and consuming a healthy diet will also help regulate your blood pressure. Follow your doctor’s advice while taking this medicine.

The most common side effects include fatigue, edema (swelling), dizziness, unusual heartbeat (palpitations), flushing, constipation, and headache. Consult your doctor if any of these bother you or do not go away.

Before taking it, let your doctor know if you have any heart, liver, or kidney problems. Pregnant or breastfeeding women should also consult their doctor for advice before taking this medicine. You also need to tell your doctor what other medicines you are taking, especially those used to treat high blood pressure or heart conditions. Avoid excessive alcohol intake while taking this medicine, as it can significantly decrease your blood pressure and make you feel dizzy or light-headed.
