Formoterol Inhaler (Atimos, Foradil, Oxis)
Comprehensive guide to formoterol inhalers for asthma and COPD management, including uses, dosage, side effects, and safety advice.
Formoterol is a long-acting bronchodilator medication delivered via inhaler to treat asthma and chronic obstructive pulmonary disease (COPD). It relaxes bronchial muscles, widening airways to improve breathing.
About formoterol
Formoterol belongs to the class of long-acting beta-2 adrenergic agonists (LABAs). It selectively stimulates beta-2 receptors in the lungs’ bronchial smooth muscle, causing relaxation and bronchodilation. This increases airflow, reducing symptoms like wheezing, shortness of breath, and chest tightness.
Also known as eformoterol, it provides up to 12 hours of relief, making it suitable for maintenance therapy rather than acute attacks. Formoterol is never used alone for asthma; it must be combined with an inhaled corticosteroid (ICS) to prevent exacerbations and reduce risks like asthma-related death.
Common brands include Atimos Modulite (pMDI), Foradil (capsules for Aerolizer), and Oxis Turbohaler (dry powder inhaler). Some formulations combine formoterol with steroids (e.g., budesonide/formoterol) or other bronchodilators like aclidinium.
| Brand | Form | Strengths | Key Features |
|---|---|---|---|
| Atimos Modulite | Pressurized metered-dose inhaler (pMDI) | 6 mcg, 12 mcg per actuation | Aerosol spray; shake before use |
| Foradil | Capsules for Aerolizer device | 12 mcg capsules | Pierce and inhale powder |
| Oxis Turbohaler | Dry powder inhaler (Turbohaler) | 6 mcg, 12 mcg per dose | Twist to load dose; breath-activated |
When not to use formoterol
- Acute asthma or COPD attacks: Formoterol does not relieve sudden bronchospasm. Use a short-acting beta agonist (SABA) like salbutamol instead.
- Monotherapy in asthma: LABAs alone increase asthma-related death risk. Always pair with ICS.
- Hypersensitivity: Avoid if allergic to formoterol, lactose (in dry powder forms), or milk proteins.
- Uncontrolled conditions: Not for severe acute respiratory issues without other therapies.
Types of formoterol inhaler
Formoterol comes in multiple delivery systems for patient convenience:
- Aerolizer (Foradil): Hard gelatin capsules containing 12 mcg powder, pierced by the Aerolizer device for inhalation.
- Turbohaler (Oxis): Breath-activated dry powder device with 6 mcg or 12 mcg doses. Twist grip to load, inhale forcefully.
- pMDI (Atimos Modulite): Aerosol canister delivering 6 mcg or 12 mcg per puff. Requires coordination or spacer.
- Nebulizer solution: 20 mcg vials for nebulization, twice daily for COPD.
Combination inhalers simplify regimens: budesonide/formoterol (Symbicort) for asthma/COPD; beclometasone/formoterol for asthma.
How and when to use formoterol inhalers
Use exactly as prescribed, typically twice daily (morning and evening, 12 hours apart). Rinse mouth after to prevent thrush if combined with steroid.
Atimos Modulite (pMDI)
- Shake inhaler well.
- Exhale fully.
- Place mouthpiece between lips, inhale deeply while actuating.
- Hold breath 10 seconds, exhale slowly.
- If second puff needed, wait 30 seconds.
Prime before first use or after 3 days unused.
Foradil Aerolizer
- Insert capsule into device chamber.
- Pierce both ends by pressing buttons.
- Exhale away from device.
- Inhale deeply and forcefully; repeat if powder remains.
- Discard used capsule.
Use Aerolizer only with Foradil capsules.
Oxis Turbohaler
- Unscrew/unsnap cover.
- Hold upright, twist grip fully both ways until click.
- Exhale away.
- Inhale deeply/forcefully.
- Twist closed; dose counter advances.
Do not shake or breathe into device.
General tips: Keep inhaler clean/dry. Track doses via counter. Use spacer for pMDI if coordination issues. Not for acute relief—keep SABA handy.
Dosage
Dosage varies by age, condition, and form. Always follow doctor’s instructions.
| Condition | Adults/Children ≥5-6 yrs | Children <5 yrs |
|---|---|---|
| Asthma prevention (powder) | 12 mcg (1 capsule/dose) every 12 hrs | Doctor-determined |
| Exercise-induced bronchospasm | 12 mcg 15 mins before exercise | Doctor-determined |
| COPD maintenance (powder) | 12 mcg every 12 hrs | Doctor-determined |
| COPD (nebulizer solution) | 20 mcg (1 vial) twice daily; max 40 mcg/day | Not recommended |
Do not exceed prescribed doses—increases side effect risks.
How to use inhalers if you have shaky hands
Shaky hands from beta agonists? Use:
- Spacers/Valved Holding Chambers (VHC): Attach to pMDI; inhale slowly after spray.
- Breath-activated devices: Turbohaler/Aerolizer don’t require hand-lung coordination.
- Nebulizers: Hands-free mist inhalation over 5-10 mins.
- Caregiver assistance: Steady hands for pMDI actuation.
Getting the most from your treatment
- Use daily, even symptom-free, for prevention.
- Combine with ICS for asthma; don’t stop without doctor advice.
- Track symptoms/peak flow; report poor control.
- Avoid triggers: smoke, allergens, colds.
- Stop smoking; get flu/COVID vaccines.
- Pulmonologist review annually.
Side effects
Common (affects >1/100):
- Tremor, headache, fast heartbeat, dry mouth, throat irritation.
Serious (seek urgent help):
- Chest pain, severe palpitations, allergic reactions (rash, swelling), worsening breathing, high blood sugar.
Long-term: Paradoxical bronchospasm, hypokalemia, QT prolongation.
Cautions
- Heart issues: Angina, arrhythmias, hypertension—monitor closely.
- Diabetes/thyroid: May worsen control.

Does it interact with alcohol?
No known major interactions, but consult doctor.
