## Direct answer

One drug and one endoscopic procedure together — a non-selective beta-blocker plus band ligation — is what stands between a cirrhotic patient and the next variceal haemorrhage, and the combination outperforms either alone. The beta-blocker is titrated to a heart-rate target (resting rate reduced by about 25%, or to 55–60 per minute), carvedilol is the more potent option where blood pressure tolerates it, and banding continues every 2–4 weeks until varices are eradicated. Rebleeding despite this regimen escalates to a covered TIPS.

## What you must remember

- **The risk being managed:** without secondary prophylaxis, most patients rebleed within one to two years — the justification for starting the regimen immediately after the index bleed is controlled.
- **Standard combination:** non-selective beta-blocker (propranolol, nadolol, or carvedilol) plus endoscopic variceal ligation — additive reduction in rebleeding versus either alone.
- **Propranolol titration:** start low (about 20 mg twice daily) and increase until the resting heart rate falls by roughly 25% or reaches 55–60 bpm — the classic exam target; nadolol is the once-daily alternative.
- **Carvedilol:** 6.25–12.5 mg/day; its added alpha-blocking effect lowers portal pressure more than propranolol at equivalent haemodynamic cost — preferred where tolerated, but watch for hypotension in ascitic patients.
- **Contraindications to NSBB:** asthma, severe bradyarrhythmia, hypotension; decompensated ascites needs dose caution rather than automatic avoidance.
- **EVL schedule:** sessions every 2–4 weeks until eradication, then surveillance endoscopy at 3–6 months and 6–12 monthly thereafter — varices regrow, and so does the programme.
- **Failure pathway:** rebleeding despite combined therapy → covered TIPS (or surgical shunt in well-preserved liver function); transplant evaluation follows.
- **Adjuncts from the acute episode:** ceftriaxone for 4–7 days reduces infection and rebleeding; over-transfusion (haemoglobin pushed above 7–8 g/dL) refills the portal tree — both are examinable management details.

## Building the regimen after the first banding session

A 51-year-old man with alcohol-related cirrhosis survived his first oesophageal variceal bleed — two banding sessions, ceftriaxone for five days, haemoglobin held at 7.5 g/dL. Discharge planning is where secondary prophylaxis is actually written. The endoscopy arm: bands again in 2–4 weeks, repeating until the variceal columns are eradicated, then a check at 3–6 months and 6–12 monthly — the calendar is part of the prescription. The pharmacological arm: carvedilol 3.125 mg twice daily if his blood pressure allows, escalating to 12.5 mg/day while his pulse is watched for the 25% fall or the 55–60 floor — whichever his autonomic system reaches first. Alongside both, the aetiology gets treated, because prophylaxis of the veins without treatment of the liver is half a plan: abstinence counselling and, where relevant, antiviral therapy through the viral hepatitis programme. Then the contingency is rehearsed on the discharge summary itself: any further haematemesis means TIPS, not another round of banding — a covered stent through the hepatic vein into the portal system decompresses the collaterals that banding keeps losing to. The exam rewards the sentence structure: drug plus bands, titrated to the pulse, scheduled to eradication, TIPS on failure — four clauses, no improvisation.

## Why the heart rate target matters

The examiner's pharmacology question hides in the pulse: beta-blockers in portal hypertension work by cutting cardiac output and splanchnic vasoconstriction, and the heart rate is the only bedside meter of that dose — hence the 25% reduction or 55–60 bpm target, and hence why " propranolol 20 mg twice daily, fixed forever" is the half-answer that fails the titration mark. The second trap is carvedilol's double edge: more potent portal pressure reduction, but an alpha-mediated drop in systemic pressure that can unseat an ascitic, hypotensive patient — knowing when not to push it is part of knowing the drug. Third, the myths: NSBBs are no longer automatically stopped for SBP or refractory ascites (the pendulum has swung back to individualised judgement), and they are not "contraindicated in all decompensation" — severe hypotension and asthma are the hard stops. Finally, the schedule trap: eradication is not immunity — varices recur after successful banding, which is why the 6–12 monthly surveillance endoscopy exists; candidates who declare the patient "cured after three sessions" miss the lifelong loop the guidelines describe.

## Frequently asked questions

### What is standard secondary prophylaxis after a variceal bleed?

Combined non-selective beta-blocker and endoscopic variceal ligation — superior to either alone in preventing rebleeding.

### How is propranolol titrated?

To a resting heart rate reduced by about 25% or to 55–60 bpm — the clinical proxy for adequate portal pressure reduction.

### Why might carvedilol be preferred?

At 6.25–12.5 mg/day it lowers portal pressure more than propranolol (added alpha-blockade), though hypotension limits it in decompensated patients.

### What is the EVL follow-up schedule?

Sessions every 2–4 weeks until eradication, then surveillance endoscopy at 3–6 months and 6–12 monthly lifelong, since varices recur.

### What is done when rebleeding occurs despite combination therapy?

Covered TIPS (or surgical shunting with good liver reserve), with transplant evaluation — escalation is planned, not improvised.
