What happens if Winrevair (generic name) is taken 3 days late due to being out of town?

Managing a Missed Dose of Winrevair

If a dose of Winrevair is missed for 3 days due to being out of town, you should take it as soon as possible and adjust your schedule to maintain the standard 3-week dosing intervals going forward. 1

Specific Guidance for Missed Winrevair Doses

According to the FDA label for Winrevair (sotatercept-csrk), the following protocol should be followed for missed doses:

• If a dose is missed:
  • If it has been 3 days or fewer since the scheduled date: Administer as soon as possible, then follow your usual schedule for the next dose.
  • If it has been more than 3 days since the scheduled date: Administer as soon as possible, but adjust your schedule to maintain 3-week dosing intervals. 1

Clinical Implications of Missed Doses

Missing a dose of Winrevair by 3 days is not likely to significantly impact treatment efficacy for pulmonary arterial hypertension, as the medication is designed to be administered once every 3 weeks. The FDA label specifically accounts for this scenario and provides clear guidance.

Important Considerations:

1. Do not double the dose to make up for the missed dose.
2. Do not attempt to "catch up" by shortening the interval to your next scheduled dose.
3. Maintain the 3-week interval between doses going forward, counting from the day you take the delayed dose.

Monitoring After a Missed Dose

After taking the delayed dose:

• Continue with regular monitoring of hemoglobin and platelet count as prescribed by your healthcare provider.
• Be vigilant for any unusual symptoms and report them to your healthcare provider.

Common Pitfalls to Avoid

• Do not skip the dose entirely - This could lead to suboptimal treatment of your condition.
• Do not take multiple doses to compensate for the missed dose.
• Do not change your dosing schedule without consulting your healthcare provider.
• Do not delay reporting any adverse effects that may occur after taking the delayed dose.

When to Contact Your Healthcare Provider

Contact your healthcare provider immediately if:

• You miss your dose by more than 3 days and are unsure how to proceed
• You experience any unusual symptoms after taking the delayed dose
• You have questions about adjusting your dosing schedule

While the evidence on missed doses of medications is generally limited 2, the FDA label for Winrevair provides clear guidance specific to this medication, which should be followed precisely to maintain treatment efficacy and safety.
