Wash hands before use. Sterilize the cup by boiling in water for 5–10 minutes before first use and after each cycle. Fold and insert into the vagina; ensure it opens fully. Empty every 4–8 hours (up to 12 hours depending on comfort and flow), rinse with clean water/mild unscented soap, and reinsert. Remove by breaking the seal (pinch base) and gently pull out.
Always follow your doctor's prescription. Do not self-medicate.
