Prescription Titration
Quick Definition
Prescription titration is the structured stepwise increase of a medication dose over time, used to manage tolerability while reaching a target therapeutic dose. Titration schedules are typically specified in the FDA-approved label and are particularly important for medications like GLP-1 agonists and TRT.
In Depth
Prescription titration is the deliberate, gradual increase of a medication dose to allow the body to adapt and to manage tolerability. The schedule is typically specified in the FDA-approved label and is part of the regulatory record for the medication.
Titration is particularly relevant for medications where:
- Side effects are concentrated at the start of therapy and improve with continued exposure (GLP-1 receptor agonists). - The therapeutic window is narrow and requires careful dose adjustment to optimal level (TRT, thyroid replacement). - The therapeutic effect builds over time (some psychiatric medications).
Examples of titration in this site's clinical scope:
- Wegovy (semaglutide for weight management): 0.25 mg → 0.5 mg → 1.0 mg → 1.7 mg → 2.4 mg, with each step held for 4 weeks. - Zepbound (tirzepatide for weight management): 2.5 mg → 5 mg → 7.5 mg → 10 mg → 12.5 mg → 15 mg, with each step held for at least 4 weeks. - TRT injectable: typically initiated at a starting dose with serum testosterone reassessed at 3 months for dose adjustment.
The "tolerated" criterion for advancing through a titration schedule is that side effects at the current dose are mild and the patient is stable. If a patient cannot tolerate a step, the standard response is generally to delay the next step rather than reduce the dose, although individual clinical situations vary.
Skipping titration steps or compressing the schedule is not standard practice. Doing so increases side effect burden without producing faster therapeutic results.
Compounded medications can be dosed at non-labeled increments. The clinical responsibility for safe titration rests with the prescriber and dispensing pharmacy. Patients on compounded preparations should confirm the specific dose at each escalation.

Compounded Medication
A compounded medication is one prepared by a licensed pharmacist for a specific patient, typically because the commercially manufactured product is unavailable, the patient cannot tolerate an inactive ingredient, or a non-standard dose is clinically required. Compounded preparations are not FDA-approved as finished drug products.
GLP-1 Receptor Agonist
A GLP-1 receptor agonist is a medication that activates the glucagon-like peptide-1 receptor, mimicking the body's GLP-1 hormone. The class is FDA-approved for type 2 diabetes and chronic weight management, and includes semaglutide, liraglutide, dulaglutide, and exenatide.
