Nifedipine (Procardia, Procardia XL) is a calcium channel blocker (CCB). It's used to treat certain heart conditions, such as chest pain (angina) and high blood pressure in adults. It mainly works by relaxing your blood vessels, making it easier for blood to flow. Nifedipine is available as an extended-release pill (ER) that's taken by mouth once daily, and a immediate-release pill (IR) that's taken three times a day. Keep in mind the nifedipine IR is rarely prescribed. Some side effects of nifedipine include swelling in the legs, dizziness, tiredness, and headache.

The extended-release tablets are taken once daily
Available as a lower-cost, generic form
Often causes swelling in the legs and feet
Not a good choice if you have heart failure because of risk for swelling
If you have severe heart disease, it can raise your risk of having a heart attack or worsening chest pain
The immediate-release capsule needs to be taken 3 to 4 times a day
Swallow nifedipine ER (Procardia XL) tablets and capsules whole. Don't chew, divide, or crush the extended-release tablets.
It takes 1 to 2 weeks to see the full effects of nifedipine ER (Procardia XL). Let your provider know if you don't see an improvement in your chest pain symptoms or blood pressure after a week.
Nifedipine ER (Procardia XL) can cause dizziness in the first few days, because it lowers your blood pressure, but your body will usually adjust. When first starting this medication or switching to a higher dose, make sure to sit or stand up slowly to avoid dizziness and risk of falling.
Nifedipine ER (Procardia XL) can cause swelling (edema) in your feet, ankles, legs, or occasionally your hands and arms.

To help with swelling in the legs or feet, try sitting and propping your feet up for a while.
Avoid eating grapefruit or drinking grapefruit juice, since it can raise the amount of nifedipine ER (Procardia XL) in your body and cause more side effects.

Nifedipine ER (Procardia XL) 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: First starting nifedipine ER (Procardia XL) or changing to a higher dose | Taking beta-blocker medications
Nifedipine ER (Procardia XL) can lower your blood pressure, even if you're taking it for chest pain. For most people, the lowered blood pressure isn't much of a problem. If it drops too much, it can cause dizziness and other side effects. Typically, the effects will go away over time as your body gets used to the lowered blood pressure, but talk to your provider if the dizziness is unbearable. If you're sensitive to low blood pressure, change positions slowly, and don't sit or stand up too fast.
Risk factors: Severe heart vessel (coronary artery) disease | Suddenly stopping beta-blocker medications right before starting nifedipine ER (Procardia XL)
In some rare cases, in people with severely diseased blood vessels in the heart, nifedipine ER (Procardia XL) can cause chest pain that's even worse or even a heart attack. This tends to happen when starting nifedipine ER (Procardia XL) treatment or changing to a higher dose. Get medical help right away if you experience worsening or crushing chest pain, radiating jaw pain, or a racing heartbeat, as these can be signs of a heart attack.
Risk factors: Taking beta-blocker medications | Aortic stenosis (narrowing of the aortic valve)
In some rare cases, nifedipine ER (Procardia XL) can cause heart failure. This is more likely to happen if you are also taking a beta-blocker medication or if one of your heart valves (the aorta valve) is abnormally narrow, a condition called aortic stenosis. Contact your provider if you experience symptoms of heart failure, such as abnormal weight gain, difficulty breathing especially when you lie down, or swelling in your legs and feet (though this could also be a normal side effect of the medication).
Risk factors: Taking higher doses of nifedipine ER (Procardia XL)
Swelling in the legs and feet is a common side effect of nifedipine ER (Procardia XL) and tends to happen with higher doses. This side effect is usually harmless, but let your provider know if it becomes too bothersome. Swelling in the legs and feet can also be a sign of heart failure, so make sure to follow up regularly with your provider to monitor your heart health.
Risk factors: Narrowing in the stomach or intestines (strictures) | Any history of stomach or intestinal problems, including cancer, surgery, inflammation, or abnormally slow bowel movement | Taking medications that slow movement of food through the body
In some rare cases, nifedipine ER (Procardia XL) can cause blockage or an ulcer in the stomach or intestines (gut), which can be severe or even require surgery. This tends to happen to people who have a narrow part of the stomach and intestines (strictures), usually due to past injury and scarring, but it can happen to people with no history of problems. If you have any history of digestive tract problems, talk to your provider before starting this medication. Contact your provider if you experience stomach pain or bloating that doesn't go away, or if you have difficulty passing stool or gas.
Extended-release tablets (Procardia XL): The typical starting dose is 30 mg or 60 mg by mouth once daily. Based on your blood pressure or chest pain symptoms, your provider will adjust your dose after a couple of weeks. The maximum recommended dose is 120 mg daily, though people with angina rarely need higher than 90 mg daily.
Immediate-release capsules (Procardia): The typical starting dose is 10 mg by mouth three times daily. Based on your blood pressure or chest pain symptoms, your provider will adjust your dose after a couple of weeks. The typical maintenance dose ranges from 10 mg to 20 mg three times daily. The usual maximum recommended dose is 120 mg daily total.
Using this medicine with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
Using this medicine with any of the following medicines may cause an increased risk of certain side effects, but using both drugs may be the best treatment for you. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
