Nifedipine 30 mg uses?

Nifedipine 30 mg usually refers to the extended‑release (long‑acting) formulation, which is used for several conditions. The 30 mg dose is commonly prescribed for:

- Hypertension (high blood pressure)
- Chronic stable angina (chest pain due to artery narrowing)
- Vasospastic (Prinzmetal) angina
- Raynaud phenomenon (recurrent cold/blue/red fingers or toes) – often treated off-label with a dihydropyridine like nifedipine

Off‑label/less common use:
- In some settings, tocolysis (to help delay preterm labor) under close medical supervision

How it’s usually taken:
- Typically one 30 mg extended‑release capsule/tablet once daily, though some patients may start at 30 mg and may be increased to higher total daily doses (e.g., 60–90 mg) depending on response and tolerance. Always follow your doctor’s exact instructions.

Important notes:
- Do not crush or chew extended‑release nifedipine; swallow whole.
- Take with a consistent schedule; can be taken with or without food.
- Grapefruit juice can raise nifedipine levels and side effects; limit or avoid it.
- Common side effects: ankle/swelling (edema), headache, flushing, dizziness, palpitations, gingival overgrowth.
- Cautions: monitor blood pressure; avoid if you have severe hypotension or certain types of heart failure. Inform your clinician about other medicines you take (antihypertensives, nitrates, certain antibiotics/fungals) due to interactions.

If you share the exact product (brand name) or your condition, I can tailor this to that formulation and provide more specific guidance. And always, follow your prescriber’s instructions.
