What dose of pirfenidone is typically used?
Pirfenidone dosing is usually started low and increased gradually to reduce side effects, then maintained as a daily regimen. The exact schedule and capsule strength depend on the specific product and indication.
What does the usual titration schedule look like?
A common approach is:
- Start with a low total daily dose.
- Increase in steps over the first few weeks to reach the target daily dose.
- Continue at the target dose afterward unless dose reduction is needed for side effects.
What dose do patients take long-term?
After titration, patients generally take a fixed daily total dose in divided administrations (often multiple times per day), continuing long term while monitored for tolerability.
How should the dose change if side effects happen?
Dose modifications are commonly used if patients develop treatment-limiting adverse effects (for example, intolerance related to liver tests, GI effects, or skin reactions). Clinicians may reduce the dose or pause treatment, then restart or adjust based on recovery.
Are there dosing differences by condition or country?
Yes. Pirfenidone labeling can differ by:
- The approved indication (and the disease being treated)
- The strength of available tablets/capsules
- Local prescribing information and regulatory guidance
Where can I confirm the exact dose for my specific product?
Check the dosing table in the prescribing information for the exact pirfenidone brand and strength you have. If you tell me the country and the tablet/capsule strength (for example, mg per tablet), I can help map that to the labeled daily regimen.
Can you share the formulation so the dose can be specified precisely?
Reply with:
1) your pirfenidone strength (mg per capsule/tablet), and
2) what it’s prescribed for (if you know), and
3) your country (or whether you’re using brand-name labeling).
Then I can give the precise titration and maintenance dosing amounts that match the label.
