How does this medication work? What will it do for me?

These medications work in different ways to open the airways and make breathing easier.

What form(s) does this medication come in?

The Respimat® inhalation device is a grey reusable plastic device with an orange cap that is specially designed for administering Combivent solution via oral inhalation.
How should I use this medication?
The recommended adult dose of ipratropium – salbutamol using the Respimat® inhalation device is 1 actuation, inhaled four times daily. Your doctor may recommend additional inhalations as needed. The maximum number of inhalations in a 24-hour period is 6.
To use the Respimat® inhaler, insert the Respimat® cartridge into the inhaler device. After the cartridge has been inserted into the inhaler, the device must be primed by loading a dose and pressing the dose release button with the inhaler pointed towards the ground, until a cloud of medication is released. Repeat 3 more times to ensure that the inhaler is ready for use. When the device is used regularly, the inhaler does not need to be re-primed. If more than 3 days have passed since last using the inhaler, it must be re-primed by actuating the inhaler once. If more than 21 days have passed since last using the inhaler, it should be primed as though it were new.
Your doctor or another health care professional, such as your pharmacist, should teach you how to use the Respimat® inhalation device. If you are unsure of how to use the device, contact your doctor or pharmacist.
After 3 months of use, safely discard the device and canister, even if there is still medication remaining in the canister.
