What Symbicort® Is and How It Works

Symbicort® is a combination asthma and COPD controller. The symbicort inhaler contains budesonide (an inhaled corticosteroid) and formoterol (a long‑acting beta2‑agonist). It delivers measured puffs through an HFA metered‑dose device. It is used for maintenance treatment and to help reduce exacerbations in appropriate patients.

CanadianInsulin is a prescription referral service. Prescriptions are verified with your clinic, and orders are filled by licensed Canadian pharmacies. We work with licensed, vetted partner pharmacies to source authentic brand medications, maintain a broad selection, and keep pricing value‑focused.

Budesonide reduces airway inflammation over time. Formoterol relaxes bronchial smooth muscle within minutes to improve airflow. Together, they improve lung function, reduce symptoms such as wheeze and chest tightness, and lower the risk of flare‑ups. Symbicort is not a substitute for a fast‑acting rescue inhaler during sudden, severe symptoms. Some care plans use it as both maintenance and reliever under clinician guidance.

Indications include maintenance therapy for asthma (select pediatric and adult patients) and chronic obstructive pulmonary disease (COPD) in adults. The inhaler is available in two strengths: 80/4.5 and 160/4.5 micrograms of budesonide/formoterol per actuation. Typical dosing is twice daily, and some patients may follow an anti‑inflammatory reliever approach as directed by their clinician.

Dosage and Usage

  • Check the labeled strength. Common strengths are 80/4.5 and 160/4.5 micrograms per inhalation.
  • Asthma: many adolescents and adults use 2 inhalations twice daily. Children may use 2 inhalations twice daily of the 80/4.5 strength, per clinician direction.
  • COPD (adults): often 2 inhalations twice daily of the 160/4.5 strength.
  • Do not exceed the maximum daily inhalations listed on the product label. Follow the prescribed plan.
  • Priming: remove the cap, shake well, then release test sprays into the air before first use, if dropped, or if unused for several days (see label for exact priming steps).
  • How to inhale: shake well, breathe out fully, seal lips around the mouthpiece, press the canister and inhale slowly and deeply, then hold breath for up to 10 seconds.
  • Rinse and spit after dosing to reduce the risk of oral thrush and hoarseness.
  • Keep the canister and actuator clean and dry. Wipe the mouthpiece weekly with a dry cloth. Do not wash the canister in water.
  • Missed dose: take the next scheduled dose. Do not double doses.
  • Use a separate fast‑acting rescue inhaler for sudden breathing symptoms unless a clinician prescribes a maintenance‑and‑reliever plan.
  • Storage: store at 20–25°C (68–77°F); excursions 15–30°C (59–86°F) are permitted. Keep away from heat and open flame.
  • Do not puncture the canister or expose it to temperatures above 49°C (120°F), including inside parked cars.
  • Keep the cap on when not in use. Avoid freezing and direct sunlight.
  • Travel: carry inhalers in a personal bag, not checked luggage. Keep the prescription label and original carton. Consider packing a spare device.
  • Reprime after long periods without use as indicated on the label.

Benefits and Savings

Symbicort brings two proven medicines together in one device. Budesonide helps calm airway inflammation, and formoterol provides rapid, sustained bronchodilation. Many patients experience fewer nighttime symptoms, better exercise tolerance, and improved lung function metrics, such as FEV1. The dose counter and consistent spray pattern support reliable day‑to‑day use.

Convenience matters. One inhaler can cover both daily maintenance and, in some care plans, symptom relief under direction of a clinician. That can simplify routines and reduce the number of devices carried. The HFA metered‑dose format works with a spacer if one is prescribed.

Many customers save 60–80% vs typical U.S. prices.

Side Effects and Safety

  • Common: throat irritation, hoarseness, cough, oral thrush (candidiasis), headache, nausea, sinusitis, nasopharyngitis.
  • Possible LABA‑related effects: tremor, palpitations, increased heart rate, nervousness.
  • Other reported: back pain, upset stomach, vomiting, muscle cramps.
  • Reduce oral thrush risk by rinsing and spitting after each dosing session.
  • Contact a clinician if paradoxical bronchospasm (worsening wheeze) occurs after inhalation.

Serious risks are uncommon but can include adrenal suppression with high or prolonged steroid exposure, effects on bone mineral density, glaucoma or cataracts with long‑term use, QT prolongation, hypokalemia, hyperglycemia, and pneumonia risk in COPD. Hypersensitivity reactions may occur in those allergic to budesonide, formoterol, or excipients. Do not stop controller therapy abruptly without medical advice.

Onset Time

Formoterol begins to work within minutes, and many users notice easier breathing shortly after dosing. Anti‑inflammatory effects from budesonide build over days. Symptom control often improves within 1–2 weeks, with maximal benefit usually reached after several weeks of regular use. Exacerbation reduction is assessed over months of consistent therapy.

Compare With Alternatives

Other ICS/LABA combination inhalers include fluticasone/salmeterol and mometasone/formoterol. Fluticasone/salmeterol uses salmeterol, which has a slower onset than formoterol. Mometasone/formoterol is another option with a comparable bronchodilator component. Device preference, dosing frequency, and specific indications often guide the choice.

For COPD or persistent asthma symptoms, adding a long‑acting muscarinic antagonist (LAMA) may help. Tiotropium is a LAMA available as the Spiriva Respimat Inhaler and as the capsule‑based Spiriva Handihaler. These are not ICS/LABA products but can complement controller therapy under clinician guidance.

Combination Therapy

  • Maintenance controller plus rescue SABA: common in asthma plans that do not use anti‑inflammatory reliever strategies.
  • Triple therapy: ICS/LABA plus a LAMA for selected COPD or severe asthma cases.
  • Leukotriene receptor antagonists (e.g., montelukast) may be added for allergic or exercise‑induced components.
  • Biologic therapies for severe eosinophilic or allergic asthma can be layered with inhaled controllers.
  • Avoid duplicate LABAs in combination with other inhalers. Review all inhaled medications to prevent overlap.
  • Strong CYP3A4 inhibitors can increase systemic steroid exposure. Monitor as directed.

Patient Suitability and Cost‑Saving Tips

Symbicort is intended for patients who need both anti‑inflammatory and bronchodilator maintenance. It is indicated for asthma in appropriate pediatric and adult groups and for COPD maintenance in adults. It is not for primary treatment of acute episodes or for status asthmaticus.

Do not use if there is a known hypersensitivity to budesonide, formoterol, or any component of the inhaler. Extra caution is needed with certain conditions, including active infections (such as tuberculosis), glaucoma or cataracts, osteoporosis, cardiovascular disease, seizure disorders, thyroid disease, diabetes, and in pregnancy or while breastfeeding. A clinician can assess risks and benefits for individual cases.

Tips to reduce costs and improve continuity of care:

  • Consider multi‑month quantities to reduce per‑order overhead.
  • Use the strength that aligns with the prescribed plan to avoid wasted doses.
  • Coordinate refills with other medications to consolidate shipments.
  • Ask about generic budesonide/formoterol availability where appropriate.
  • Set gentle reminders so supplies are reordered before the counter reaches zero.
