It seems you're asking about the use of a product, but I need a bit more information to help you accurately.

• Could you please specify which product you are referring to? The term "product" can mean many things, such as a medication, medical device, or health-related item.
• Once I know the exact product, I can explain its general purpose and how it is typically used.
• Feel free to provide the product name or type, and I’ll be happy to give you detailed information.

If this is urgent or related to a medical emergency, please contact a specialist doctor or visit the nearest emergency service.
