Renal guidance: 2, renal impairment and 4
In mild to moderate renal impairment start with 1 mg; do not exceed 2.5 mg in 24 hours. At CrCl <15 mL/min use is contraindicated. Verify the time and dose of prior triptan or ergot use before treating.

Evidence sources and renal implications
Choose a source to jump directly to its locally stored result. Qualitative precautions and evidence gaps remain visible even when no numerical clearance schedule is supplied.
Locate a word or phrase within this drug's source summaries. Choose all sources or one source to focus the search. The selection never hides warnings or source text, changes a dose, or proves that a renal finding is absent.

All source summaries, original wording and provenance
Before applying a renal protocol
Check the setting. Compare whole sources.
No patient-specific dose is calculated. Context choices only display reminders; they do not validate, hide or change any regimen.
Share a reproducible source review
Choose sources below, then open a print-ready comparison with product scope, renal method, dates and cautions. Links can pin the exact local cards; they never contain patient values or choose a dose.
Select two distinct source versions. The complete stored summaries will appear below.
Source-by-source comparison
These protocols may disagree and may apply to different settings. This view does not reconcile or endorse a patient-specific regimen.
Build a source-review outline for documentation
This creates a blank decision outline with the source identities you select, not a dose recommendation or completed clinical assessment. No patient fields are collected, saved or sent. Complete the clinical decisions in your approved documentation system.
Choose one or two sources above or use the source checkboxes below.
Renal-context checklist: population, kidney trend and dialysis
These prompts are a reading aid, not a prescription checklist or proof that all requirements have been met. No selections are stored or sent to a server.
Read the exact source scope, renal metric and date before selecting a row. No applicability assessment has been performed.
These are specific issues found during source review, not an automated judgment that one source is universally correct. A label mirror and its original label are not independent evidence.
boundary units
Naratriptan: renal daily maximum and exact-15 wording
The renal daily maximum differs from the general maximum. The dosing and PK sections use different endpoint wording around CrCl 15.
How to use this: Do not use the general daily maximum or silently assign the ambiguous endpoint.
Choose a source, then jump to its renal or dialysis section. These links locate stored text; they do not merge regimens or certify that sources agree.
Independent clinical review is pending. These selected summaries are not an approved institutional dosing protocol. Confirm the exact product, the complete current source and local policy before use.

No dialysis or renal heading shown? Read the complete source summary. Absence of a heading is not evidence that dose adjustment is unnecessary.

All content below is stored locally. Read a whole source version; do not combine its dose with another source's interval, renal metric or dialysis assumptions.
Exact product and population matter. This added page contains locally stored, source-specific clinical summaries. Historical handbook information, when present, is identified separately and may conflict with U.S. labeling. Confirm indication, population, kidney-function method, monitoring and the full prescribing information before applying a regimen.
In mild to moderate renal impairment start with 1 mg; do not exceed 2.5 mg in 24 hours. At CrCl <15 mL/min use is contraindicated. Verify the time and dose of prior triptan or ergot use before treating.

Renal dosing, restrictions and evidence limits
Severe renal impairment with CrCl <15 mL/min is contraindicated in the dosing section. In mild or moderate impairment, use a 1-mg starting dose and a maximum of 2.5 mg in 24 hours. The general 5-mg daily maximum must not be applied to this renal pathway. The pharmacokinetic discussion separately describes unstudied severe impairment as CrCl <=15; the endpoint wording differs. Do not silently reconcile the exact-15 boundary or infer a dialysis regimen.
