Lisinopril 5 mg tablet is a dose of the drug lisinopril, which is an ACE inhibitor. It’s commonly used to treat high blood pressure, heart failure, and to help after a heart attack in some people. Here’s a quick overview, but this isn’t a substitute for medical advice from your clinician.
What it’s used for
- High blood pressure (hypertension)
- Heart failure
- After a heart attack (myocardial infarction) in some cases
- Sometimes used to protect kidney function in certain conditions (e.g., diabetes), under a doctor’s guidance
What the 5 mg dose means
- 5 mg is the strength of the tablet. The actual dose you take is prescribed by your doctor and can vary by condition.
- Tablets can look different by manufacturer, but they all contain lisinopril as the active ingredient. If you’re unsure about a pill’s identity, check the label or ask a pharmacist.
Typical dosing ranges (general, not a substitute for your doctor)
- Hypertension: Often starts at 5–10 mg once daily, then may be increased up to around 20–40 mg per day (in one or two doses).
- Heart failure: Often starts at a lower dose (e.g., 2.5–5 mg daily) and may be titrated up to 20–40 mg daily, depending on tolerance and response.
- After a heart attack: Starting doses can vary; your doctor will guide you.
How to take it
- Take exactly as prescribed.
- Usually taken once daily, but some regimens use twice daily.
- Can be taken with or without food. Swallow whole; do not crush or chew unless your doctor says it’s okay.
Important safety notes
- Pregnancy: Do not use if you are pregnant; can harm the fetus. If you become pregnant, contact your healthcare provider right away.
- Kidney function and potassium: Lisinopril can affect kidney function and raise potassium levels. Your doctor will monitor this with tests.
- Angioedema: Rare but serious swelling of the face, lips, tongue, or throat can occur. Seek emergency care if this happens.
- Cough: A common side effect is a persistent dry cough.
- Dizziness or lightheadedness: Especially after the first dose or when increasing the dose.
Common side effects (not everyone gets these)
- Dizziness or lightheadedness
- Cough
- Fatigue
- Headache
- Nausea
More serious (seek medical attention if you have these)
- Signs of high potassium: unusually slow/irregular heartbeat, muscle weakness, or numbness/tingling
- Severe swelling (angioedema)
- Signs of kidney problems: unusually dark urine, swelling, or confusion
Drug interactions to be aware of
- Avoid combining with other ACE inhibitors or ARBs unless your doctor directs you.
- NSAIDs (like ibuprofen) can affect blood pressure control or kidney function.
- Potassium supplements or potassium-sparing diuretics can raise potassium too high; tell your doctor about any supplements you take.
If you want, tell me:
- Why you’re asking (prescribed medication, pill identification, or something else)
- Any conditions you have or other meds you take
- Whether you’re looking for a general overview or specific dosing for a condition
