To treat chronic obstructive pulmonary disease-related wheezing, shortness of breath, and chest tightness, formoterol oral inhalation is utilised (COPD; a group of lung diseases that includes chronic bronchitis and emphysema). Formoterol belongs to a group of drugs known as long-acting beta agonists (LABAs). Breathing becomes simpler as a result of the lungs’ opening and relaxation.

The solution (liquid) for formoterol oral inhalation is administered orally using a nebulizer (machine that turns medication into a mist that can be inhaled). Typically, it is breathed in twice daily, in the morning and in the evening, around 12 hours after your last dose. Formoterol should be inhaled at around the same times each day. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Follow the formoterol instructions exactly. Use it only as directed by your doctor, neither more nor less often.

To treat COPD attacks that come on suddenly, do not use formoterol. For use during attacks, your doctor will prescribe a short-acting beta agonist drug like albuterol (Accuneb, Proair, Proventil, Ventolin). Your doctor will likely advise you to stop regularly taking this kind of medicine but to keep using it to treat attacks if you were already doing so before starting formoterol treatment.

COPD that is rapidly deteriorating should not be treated with formoterol inhalation. If your breathing issues worsen, if you need to use your short-acting inhaler more frequently to treat COPD attacks, or if your short-acting inhaler does not improve your symptoms, call your doctor or seek emergency medical attention.

Inhaling formoterol may help you manage your symptoms, but it won’t make your disease go away. Never stop taking formoterol without consulting your doctor first. Your symptoms can get worse if you stop taking formoterol abruptly.

Follow these instructions to use a nebulizer to inhale the solution:

1. From the foil packet, take out one vial of formoterol inhalation solution.
2. See the liquid contained in the vial. It need to be transparent and colourless. If the liquid is unclear or discoloured, do not use the vial.
3. Squeeze all of the liquid from the vial into the nebulizer reservoir by twisting off the vial’s top. Do not combine formoterol in the reservoir with other drugs.
4. Attach the face mask or mouthpiece to the nebulizer reservoir.
5. Connect the compressor and nebulizer.
6. Wear the face mask or put the mouthpiece in your mouth. Turn on the compressor while seated comfortably and upright.
7. For roughly 9 minutes, until mist stops developing in the nebulizer chamber, inhale steadily, deeply, and evenly.
8. Make sure the empty vial and its lid are disposed of carefully and out of children’s reach.

Regularly clean your nebulizer. If you have any concerns about cleaning your nebulizer, carefully follow the manufacturer’s instructions and see your physician or pharmacist.

With your nebulizer, do not combine the formoterol solution with other inhaling solutions.

Before using formoterol oral inhalation,

• If you have any allergies, including to formoterol, other drugs, or any of the substances in formoterol nebulizer solution, let your doctor and pharmacist know right once. For a list of the ingredients, consult the Medication Guide or speak with your pharmacist.
• Indacaterol (Arcapta), Olodaterol (Striverdi Respimat, in Stiolto Respimat), Salmeterol (Serevent, in Advair), or Vilanterol are examples of other LABAs to mention to your doctor (in Anoro Ellipta, Breo Ellipta, Trelegy Ellipta). Your doctor will advise you on which medications to take and which to quit using.
• Inform your doctor and pharmacist about all prescription and over-the-counter drugs, vitamins, dietary supplements, and herbal products that you are now taking or intend to use. Incorporate any of the following: Amiodarone (Nexterone, Pacerone), aminophylline, antidepressants such amitriptyline, desipramine (Norpramin), clomipramine (Anafranil), imipramine (Tofranil), nortriptyline, or trimipramine (Surmontil), among others; beta blockers like nadolol (Corgard), propranolol (Inderal, Innopran), and sotalol (Betapace, Sorine), as well as labetalol (Trandate), metoprolol (Lopressor, Toprol XL, and others); dietary supplements, diuretics (often known as “water pills”), clonidine (Catapres), disopyramide (Norpace), dofetilide (Tikosyn), and epinephrine (Primatene Mist); erythromycin (E.E.S, E-Mycin, Erythrocin); cold remedies such pseudophedrine (Sudafed) and phenylephrine (Sudafed PE); monoamine oxidase (MAO) inhibitors like tranylcypromine (Parnate), isocarboxazid (Marplan), linezolid (Zyvox), phenelzine (Nardil), rasagiline (Azilect), and selegiline; quinidine (in Nuedexta), pimozide (Orap), procainamide, and steroids such dexamethasone, methylprednisolone (Medrol), and prednisone (Rayos); thioridazine with theophylline (Theochron, Theo-24). Tell your doctor about all of the medications you are taking, even any not on this list, as many other drugs may also interact with formoterol. Your physician might need to adjust the dosage of your drugs or keep a close eye on you for side effects.
• If you have asthma, let your doctor know. If you are not also on an inhaled steroid medicine, your doctor may advise against using formoterol inhalation.
• Inform your doctor if you have or have ever had diabetes, high blood pressure, seizures, a heart, liver, or thyroid disorder, an irregular heartbeat, QT prolongation (an irregular heart rhythm that can cause fainting, loss of consciousness, seizures, or sudden death), high blood pressure, or QT prolongation.
• Inform your physician if you are nursing a baby, intend to get pregnant, or are already pregnant. Call your doctor if you become pregnant while taking formoterol.
• You should be aware that formoterol inhalation occasionally results in wheezing and breathing difficulties right away. Make a quick call to your doctor if this occurs. A doctor must prescribe formoterol inhalation before you take it again.

Ask your doctor or pharmacist for more details if you believe this drug should be used for something else.

Ignore the missed dose and carry on with my normal dosing routine. To make up for a missing dose, do not take a second one.

For as long as you haven’t planned to use them, keep the formoterol nebulizer solution vials sealed in their foil bags, away from light, and from extreme heat. The nebulizer solution should be refrigerated. It can also be kept for three months at room temperature. Children should not have access to this drug.

Although many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning. http://www.upandaway.org

Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilising a medicine take-back programme is the easiest approach to get rid of your medication. To find out about take-back programmes in your area, speak with your pharmacist or the garbage/recycling department in your city. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medications website at http://goo.gl/c4Rm4p for additional information.

Call the poison control hotline at 1-800-222-1222 in the event of an overdose. Moreover, information can be found online at https://www.poisonhelp.org/help. Call 911 right once if the person has collapsed, experienced a seizure, is having difficulty breathing, or cannot be roused.

Symptoms of overdose may include the following:

• Chest pain
• Fainting
• Fast, pounding, or irregular heartbeat
• Nervousness
• Headache
• Uncontrollable shaking of a part of the body
• Seizures
• Muscle cramps
• Dry mouth
• Nausea
• Dizziness
• Excessive tiredness
• Difficulty falling asleep or staying asleep
• Thirst
• Trouble breathing

Keep all of your doctor’s appointments.

Inform your doctor and the lab staff that you are using formoterol prior to any laboratory test (particularly those involving methylene blue).

Do not share your medication with anybody else. Any queries you may have regarding medication refills should be directed to your pharmacist.

You should keep a written record of every medication you take, including any over-the-counter (OTC) items, prescription drugs, and dietary supplements like vitamins and minerals. This list should be brought with you whenever you see a doctor or are admitted to the hospital. You should always have this information with you in case of emergencies.
