Product Overview

Captopril is an ACE inhibitor used to lower blood pressure and help some types of heart failure. This 25 mg tablet is commonly prescribed and is available for delivery across Pakistan.

Key Benefits

Captopril helps by:

• Lowering high blood pressure to reduce stroke and heart attack risk.
• Reducing strain on the heart in some cases of heart failure.
• Improving response when combined with diuretics in resistant cases.

Directions for Use

Use this medicine exactly as your doctor prescribes; a short introductory note about timing is given below.

Adults

• Take the tablet as directed by your doctor.
• It is usually recommended to take on an empty stomach (about one hour before meals) for best absorption.
• Follow-up tests (blood pressure, kidney function, and electrolytes) are usually required after starting or changing dose.

Children (Paediatric)

• Use in children should only be under specialist paediatric or cardiology supervision.
• Paediatric dosing and safety are not routinely established without expert guidance.

Pregnancy & Breastfeeding

Brief statement about pregnancy and breastfeeding safety follows.

Pregnancy

• Captopril is not recommended in pregnancy and can harm the unborn baby, especially in the second and third trimesters.
• Use only if a specialist advises and with close monitoring; ideally, switch to a safer alternative before conception.

Breastfeeding

• Use during breastfeeding should be discussed with a doctor.
• Only use if the potential benefit justifies any possible risk to the baby and under medical supervision.

Precautions & Interactions

General safety notes and monitoring recommendations are given below.

Precautions

• Inform your doctor if you have kidney disease, liver disease, low blood pressure, or a history of angioedema (swelling).
• Regular blood tests for kidney function and potassium are usually needed.
• Stand up slowly if you feel dizzy; initial doses can cause low blood pressure.
• Avoid starting if planning pregnancy; discuss contraception and alternatives.

Major Drug & Product Interactions

Only the clearly relevant interaction risks are listed.

• Drugs that raise potassium (potassium supplements, potassium-sparing diuretics) — risk of high potassium.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs) — may reduce blood-pressure effect and increase kidney risk.
• Other medicines that affect the renin-angiotensin system — combined use increases risk of kidney problems and high potassium.
• Lithium — levels may rise; careful monitoring required.

Adverse Effects

Short note separating routine vs urgent effects is given below.

Common Side Effects

• Dizziness or lightheadedness (especially when standing).
• Taste changes or loss of taste.

Serious Side Effects

• Sudden facial or throat swelling (angioedema) — stop and seek emergency help.

• Signs of infection (fever, sore throat) that may indicate low white cells — seek medical advice.
• Significant worsening of kidney function or large increases in potassium — urgent review required.
