Spiriva HandiHaler: Dry powder inhaler: Do not swallow capsule. Administer at the same time each day. Do not remove capsule from blister until immediately before use. Place capsule in the center chamber of the HandiHaler Inhaler. Must only use the HandiHaler Inhaler. Close mouthpiece firmly until a click is heard, leaving dustcap open. The capsule is pierced by pressing and releasing the green piercing button on the side of the HandiHaler device. Exhale fully. Close lips tightly around mouthpiece; do not exhale into inhaler. Tilt head slightly back and inhale (rapidly, steadily, and deeply); the capsule vibration (rattle) may be heard within the device. Hold breath for a few seconds then repeat inhalation procedure using the same tiotropium capsule. Do not pierce the capsule a second time. Throw away empty capsule by tipping into a trash can without touching it; do not leave in inhaler. Keep capsules and inhaler dry. Discard any capsules that are exposed to air and not used immediately.

If not used for more than 21 days, actuate the inhaler until an aerosol cloud is visible and then repeat the process three more times to prepare the inhaler for use.
Inhalation: For oral inhalation only.

Uncontrolled asthma is associated with adverse events in pregnancy (increased risk of perinatal mortality, preeclampsia, preterm birth, low birth weight infants, cesarean delivery, and the development of gestational diabetes). Poorly controlled asthma or asthma exacerbations may have a greater fetal/maternal risk than what is associated with appropriately used asthma medications. Maternal treatment improves pregnancy outcomes by reducing the risk of some adverse events (eg, preterm birth, gestational diabetes) (ERS/TSANZ [Middleton 2020]; GINA 2023).
Although data related to tiotropium use in pregnancy are limited, use is likely acceptable. Maternal asthma symptoms should be monitored monthly during pregnancy (ERS/TSANZ [Middleton 2020]).
Data collection to monitor pregnancy and infant outcomes associated with asthma and the medications used to treat asthma in pregnancy is ongoing. Health care providers are encouraged to enroll exposed pregnant patients in the MotherToBaby Pregnancy Studies conducted by the Organization of Teratology Information Specialists (877-311-8972 or https://mothertobaby.org). Patients may also enroll themselves.
It is not known if tiotropium is present in breast milk.
According to the manufacturer, the decision to breastfeed during therapy should consider the risk of infant exposure, the benefits of breastfeeding to the infant, and the benefits of treatment to the mother.
