Does generic mean weaker?

What should you confirm before switching?

Ask the prescriber or pharmacist to confirm the exact product, strength, number of inhalations and refill quantity. Have the new device demonstrated, even if you have used a dry powder inhaler before. Tell them if cost or difficulty operating your current device is the reason for the change.

Keep the package instructions with the inhaler. Do not assume a generic switch means you should take both products together. Ask which product belongs in your current treatment plan and what to do with remaining supplies.

Which safety details matter here?
