What is nifedipine er 30 mg used for?

Nifedipine ER 30 mg is a calcium channel blocker used for long-term management of certain cardiovascular conditions. Specifically:

- Primary uses
- Hypertension (high blood pressure)
- Chronic stable angina (chest pain due to reduced blood flow to the heart)
- It can also be used for other blood vessel-related conditions like certain types of vasospasm or Raynaud phenomenon (less common), and is sometimes used off-label to help delay preterm labor in pregnancy under supervision.

- How it works
- It relaxes and widens blood vessels, which lowers blood pressure and reduces the heart’s workload, helping prevent chest pain.

- Typical dosing (what a 30 mg ER tablet suggests)
- Often prescribed as 30 mg once daily, and your doctor may adjust the dose based on response.
- Commonly increased to 60 mg once daily, and sometimes up to 90 mg daily, depending on the condition being treated and tolerance.
- Take exactly as prescribed. Do not crush or chew the tablet; swallow whole. ER tablets are meant to release slowly over time.

- Administration tips
- Take at the same time each day.
- Can be taken with or without food.
- Do not stop abruptly without talking to your doctor, as this can cause a rebound in blood pressure or chest pain.
- Avoid grapefruit juice in large amounts, as it can raise nifedipine levels.

- When to contact a clinician or seek urgent care
- Signs of very low blood pressure (dizziness, fainting), chest pain that is not relieved by the medicine, severe swelling of ankles/feet, or allergic reactions.
- If you’re pregnant or breastfeeding, or have severe heart failure, liver disease, or kidney disease—discuss safety with your doctor.
