Nicardipine (Cardene) can cause your blood pressure to drop when you stand up from a sitting or lying down position. When you first start nicardipine (Cardene) or switch to a higher dose, make sure to stand up slowly to avoid falling from the dizziness.
Since nicardipine (Cardene) lowers your blood pressure, it might cause dizziness and sleepiness. See how you feel on this medication before you drive or operate machinery.
Nicardipine (Cardene) can cause your feet to swell. Let your provider know if this is an issue for you. They may need to change your dose or medication.

Nicardipine (Cardene) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Congestive heart failure | Having heart failure and taking a beta blocker
Though rare, some people taking nicardipine (Cardene) reported worsening or more frequent angina (chest pain). This was more common at the start of treatment or when they switched to a higher dose.
In addition, some people with heart failure experienced worsening symptoms while taking nicardipine (Cardene).

Nicardipine (Cardene) can occasionally cause symptoms of low blood pressure (symptomatic hypotension), such as dizziness, lightheadedness, blurred vision, or fainting. Let your provider know if you have a history of a stroke, because this risk can be especially dangerous. Your provider might adjust your dose and have you monitor your blood pressure during your treatment.
Risk factors: Liver failure | Kidney failure
Nicardipine (Cardene) gets processed through the liver, so you might have more of the medication build up in your body if you have liver problems. The amount of nicardipine (Cardene) might also be higher in your body if you have kidney problems. With this in mind, your provider might lower your dose of nicardipine (Cardene) if you have liver or kidney problems.
The typical starting dose is 20 mg by mouth 3 times daily. Your provider will adjust your dose depending on your response to the medication. Your dose might differ if you have kidney, liver, or heart problems.
