If you’re asking about “nifedipine 30 mg,” 30 mg is a common dose for extended-release nifedipine, used mainly for high blood pressure and angina. A few key points:
- Formulations:
- Extended-release (SR/XL): 30 mg, 60 mg, sometimes higher, usually taken once daily.
- Immediate-release (IR): available in different strengths, but short-acting nifedipine is used less often today because of a higher risk of rapid blood pressure drops.
- Typical dosing (general guidelines; exact dose depends on your condition and formulation):
- Hypertension: starting around 30 mg once daily (SR), may be increased to 60–90 mg daily or split dosing depending on response.
- Chronic stable angina: 30–60 mg once daily (SR) or as prescribed.
- Do not change the dose or switch formulations without your clinician’s guidance.
- How to take:
- Extended-release tablets/capsules should be swallowed whole; do not crush or chew.
- Take with or without food, at the same time each day.
- Avoid grapefruit juice or limit it, as it can raise nifedipine levels in the blood with some formulations.
- Common side effects:
- Dizziness, flushing, swelling of ankles/feet, headache, palpitations, gingival overgrowth.
- If you notice severe dizziness, fainting, swelling of legs/feet, shortness of breath, or chest pain, seek medical care.
- Important interactions and cautions:
- Can interact with other blood pressure medicines, beta-blockers, and certain antifungals or antibiotics that affect the same enzyme system (CYP3A4).
- Use with caution in kidney or liver disease; discuss other medications you take.
