Olodaterol is used as a long-term (maintenance) treatment to prevent and decrease wheezing and shortness of breath caused by breathing problems (such as chronic obstructive pulmonary disease, including chronic bronchitis and emphysema). Olodaterol belongs to the class of drugs known as long-acting beta agonists (LABAs). Olodaterol is also known as a bronchodilator. It works by relaxing the muscles around the airways so that they open up and you can breathe more easily. Controlling symptoms of breathing problems can decrease time lost from work or school.

This medication does not work right away and should not be used for sudden attacks of breathing trouble. Your doctor must prescribe a quick-relief medicine/inhaler (such as albuterol, also known as salbutamol) for sudden shortness of breath while you are using olodaterol. You should always have a quick-relief inhaler with you.

Olodaterol is not approved to treat asthma. People with asthma using long-acting inhaled beta agonists (such as olodaterol) without also using an inhaled corticosteroid may have an increased risk of serious (sometimes fatal) breathing problems.

Read the Patient Information Leaflet provided by your pharmacist before you start using this medication and each time you get a refill. Follow the illustrated directions for the proper use of this medication. If you have any questions, ask your doctor or pharmacist.

Follow the instructions for priming the inhaler if you are using it for the first time, or if you have not used it for a long time (such as more than 3 days or 21 days). When priming the inhaler, make sure to spray toward the ground (away from the face) so that you do not get the medication into your eyes.

Inhale this medication by mouth as directed by your doctor, usually once daily. Wait at least 1 minute between each inhalation.

If you are using other inhalers at the same time, wait at least 1 minute between the use of each medication.

Do not use more of this medication or use it more often than prescribed since this may cause serious side effects. Do not use more than 2 inhalations of olodaterol a day.

Use this medication regularly to get the most benefit from it. To help you remember, use it at the same time each day. Do not stop taking this medication without consulting your doctor.

If you have been using a quick-relief inhaler (albuterol, salbutamol) on a regular daily schedule (such as 4 times daily), your doctor will direct you to stop this schedule and only use the quick-relief inhaler as needed for sudden shortness of breath. Consult your doctor for details.

Learn which of your inhalers you should use every day and which you should use if your breathing suddenly worsens (quick-relief drugs). Ask your doctor ahead of time what you should do if you have new or worsening cough or shortness of breath, wheezing, increased sputum, waking up at night with trouble breathing, if you use your quick-relief inhaler more often, or if your quick-relief inhaler does not seem to be working well. Learn when you can treat sudden breathing problems by yourself and when you must get medical help right away.

Tell your doctor if your symptoms do not get better or if they get worse.

Nervousness, shaking (tremor), and trouble sleeping may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

This medication may raise your blood pressure. Check your blood pressure regularly and tell your doctor if the results are high.

Tell your doctor right away if you have any serious side effects, including:

• pounding heartbeat
• muscle cramps/weakness
• increased thirst/urination
• joint pain

Get medical help right away if you have any very serious side effects, including:

• chest pain
• rapid breathing
• fast/irregular heartbeat
• severe dizziness
• fainting

Rarely, this medication has caused severe (possibly fatal), sudden worsening of breathing problems (paradoxical bronchospasm). If you have trouble breathing or sudden wheezing, use your quick-relief inhaler and get medical help right away.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including:

• rash
• itching/swelling (especially of the face/tongue/throat)
• severe dizziness
• trouble breathing

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Before taking olodaterol, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Before using this medication, tell your doctor or pharmacist your medical history, especially of:

• heart problems (such as irregular heartbeat, angina, previous heart attack)
• high blood pressure
• diabetes
• seizures
• overactive thyroid (hyperthyroidism)

Olodaterol may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.

The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using olodaterol, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions:

• certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG)
• family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death)

Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using olodaterol safely.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

Older adults may be more sensitive to the side effects of this drug, especially QT prolongation (see above).
