How Much Cagrilintide Should You Take? A Practical Dosing Guide

Cagrilintide at a glance:

• Drug class: Long-acting amylin analog
• Manufacturer: Novo Nordisk
• Route: subcutaneous injection
• Typical frequency: once weekly
• Half-life: approximately 7 days
• Receptor target: amylin receptors (calcitonin receptor + RAMP)

Dosing Cagrilintide correctly isn't complicated, but the details matter. The standard schedule is once weekly via subcutaneous injection, and the key decisions happen during titration.

Standard Dosing Schedule for Cagrilintide

Phase 2 trials tested doses up to 4.5 mg weekly as monotherapy. Now primarily developed in combination with semaglutide as CagriSema.

The typical schedule for Cagrilintide is once weekly via subcutaneous injection. Half-life of approximately 7 days explains why this schedule works — the drug stays active long enough to support that interval.

Titration: Why Starting Low Matters

For incretin therapies, gradual titration is the standard approach. The starting doses listed above are not therapeutic — they exist to let the body adapt and to reduce gastrointestinal symptoms (nausea, vomiting, diarrhea).

A typical titration plan for Cagrilintide holds each dose step for at least four weeks before moving up. Faster titration is associated with more dropouts due to side effects.

Missed Doses

If a dose of Cagrilintide is missed: for weekly schedules, the rule of thumb is to take it as soon as remembered if within a defined window, otherwise skip it and resume the regular schedule. The exact window depends on the half-life (approximately 7 days) and the specific product label. Never double up to make up for a missed dose.

Dose Adjustments

Dose adjustments may be needed for the following:

• Significant weight loss or weight gain
• Side-effect intolerance at the current step
• Changes in renal or hepatic function
• Drug interactions (particularly relevant for any concurrent medications)

We cover the side-effect side of dose decisions in Cagrilintide side effects and the cost angle of dose escalation in Cagrilintide cost.

What the Trials Used

Published trial data for Cagrilintide comes primarily from: Lau et al. 2021, Lancet — phase 2 monotherapy and combination data.

That data drives the labeled dosing range, which is what physicians prescribe by.

Special Populations

The dosing guidance above applies to general adult use. Special populations — pregnancy, pediatric, severe renal impairment, hepatic dysfunction, elderly with frailty — require individualized assessment that this page can't substitute for.

For Cagrilintide: the standard contraindications for this drug class apply.

Bottom Line

The single biggest dosing mistake we see with Cagrilintide is impatience — skipping titration steps to get to the goal dose faster. It almost always backfires.
