A prescription-only, dry powder inhaler designed for the daily, long-term maintenance treatment of asthma and Chronic Obstructive Pulmonary Disease (COPD). It combines an anti-inflammatory medicine and a long-acting reliever to keep the airways open over a continuous 12-hour window.
🚨 Important Classification Rule: Seretide Diskus is strictly a preventer (maintenance) inhaler and must be used every single day. Do not use it to treat a sudden, acute asthma attack or severe breathlessness. You must always carry a fast-acting rescue inhaler (such as salbutamol) to treat sudden breathing flare-ups.
The Diskus device contains a built-in foil strip with pre-dispensed blisters of medication. Each time you slide the lever, a tiny blister is pierced inside to ready a fine powder for inhalation.
It treats respiratory conditions using a dual-action therapeutic mechanism:
Targeted Corticosteroid Control (Fluticasone Propionate): Fluticasone is a powerful localized anti-inflammatory steroid. It works systemically on a local level within the lungs to reduce tissue swelling, hypersensitivity, and irritation in the walls of the small air passages, making long-term breathing progressively easier.
Long-Acting Bronchodilation (Salmeterol Xinafoate): Salmeterol is a long-acting $\beta_2$-receptor agonist (LABA). It continuously relaxes the smooth muscles surrounding your breathing tubes, preventing your airways from spasming or clamping shut for up to 12 hours per dose.
Your doctor will select the appropriate strength based on the severity of your respiratory symptoms:
Seretide 50/100 Diskus: 50mcg Salmeterol / 100mcg Fluticasone.
Seretide 50/250 Diskus: 50mcg Salmeterol / 250mcg Fluticasone.
Seretide 50/500 Diskus: 50mcg Salmeterol / 500mcg Fluticasone.
Severe Milk Protein Allergies: The inactive carrier powder in the device is lactose monohydrate. While usually safe for simple lactose intolerance, it contains trace amounts of milk proteins and must be avoided by individuals with severe milk allergies.
Cardiovascular Conditions: Use with caution if you have a history of severe heart disease, high blood pressure, or irregular heart rhythms (arrhythmias), as bronchodilators can occasionally cause a brief acceleration in pulse rate.
Drug Interactions ($\beta$-Blockers): Never take alongside non-selective beta-blockers (like propranolol) used for blood pressure or heart conditions, as they can directly counteract the bronchodilator component and cause severe airway tightening.
Because the Diskus is a breath-activated dry powder inhaler, you do not need to coordinate pressing a spray canister while breathing in. However, you must breathe in quickly and deeply to draw the dry powder out of the chamber and settle it deep into your lungs.
1.Slide the thumbgrip open until it clicks:Device Opening.
Hold the outer plastic case in one hand. Place the thumb of your other hand on the built-in thumbgrip and push it away from you as far as it goes until a click reveals the mouthpiece.
2.Slide the loading lever forward completely:Dose Loading.
Hold the device horizontally like a flat wheel. Slide the plastic lever away from you until you hear/feel a distinct click. This moves a fresh powder dose into the mouthpiece chamber. Do not play with or reset this lever unnecessarily, or you will waste medication.
3.Breathe out entirely away from the device:Lung Emptying.
Hold the device level and away from your mouth. Exhale fully to empty your lungs of air. Never breathe out into the Diskus mouthpiece, as moisture from your breath will clump the fine dry powder.
4.Seal your lips and breathe in quickly and deeply:Rapid Inhalation.
Bring the Diskus level to your mouth. Place the mouthpiece firmly between your teeth and seal your lips tightly around it. Inhale forcefully, rapidly, and deeply through your mouth—not your nose.
5.Hold your breath for a full 10 seconds:Sedimentation.
Remove the device from your lips. Close your mouth and hold your breath for up to 10 seconds (or for as long as is comfortable) to let the micro-droplets settle inside your lung airways. Breathe out slowly.
6.Rinse your mouth out thoroughly with water:Oral Hygiene.
Slide the thumbgrip back toward you to close the device. Always rinse your mouth out with plain water and spit it out after your dose to clean away residual steroid dust, completely preventing vocal hoarseness and oral thrush (fungal mouth infections).
Because it acts directly on the respiratory lining, systemic updates are rare when used at the prescribed dose, though some individuals may notice:
A mild, transient shaking or tremor in the hands, or a brief headache (associated with the salmeterol component).
A brief, mild acceleration in pulse rate or localized muscle cramps.
Localized throat irritation, vocal hoarseness, or minor coughing if oral rinsing is skipped.
How do I know when the Seretide Diskus is empty?
There is a built-in mechanical dose counter window on the side of the plastic case that counts down from 60 to 0. When you reach the final 5 doses, the numbers will display in bright red to warn you that your supply is running low. Once it reads 0, discard the device, as no medication remains in the blisters.
Can I use a spacer device with my Seretide Diskus?
No, absolutely not. Spacer chambers are designed exclusively for pressurized aerosol mist inhalers (MDIs). Because a Diskus requires the high-speed suction of your own rapid breath to pull the dry powder out of its blister, a spacer cannot be utilized.
Should I stop taking Seretide as soon as my daily wheezing stops?
No. This is a common tracking error. Asthma and COPD are chronic conditions. Seretide acts as a continuous shield; it only prevents airway swelling and tightening if it is taken consistently twice a day, every day, even when you feel completely healthy and symptom-free.
You can purchase genuine, factory-sealed Seretide Diskus devices (in 100mcg, 250mcg, and 500mcg strengths) online through Sanlive Pharmacy & Stores for secure payment and fast, reliable same-day delivery directly to your home, office, or clinic within Lagos, Abuja, and Port Harcourt.
Important Notice: This information is for educational support purposes only. Seretide Diskus is a prescription-grade respiratory medication that should be used strictly under the direction of a qualified pulmonologist or physician. If your breathing worsens or your rescue inhaler fails to relieve a sudden attack, seek immediate emergency medical care.
