Tablet/Syrup: Should be taken on an empty stomach. Take 1 hr before or 2 hr after meals. Aerosol Metered-Dose Inhaler Prime the inhaler before using for the first time and in cases where the inhaler has not been used for >2 weeks by releasing 4 “test sprays” into the air, away from the face Patient instructions for administration Shake well before each use Breathe out fully through the mouth, expelling as much air from your lungs as possible; place the mouthpiece fully into the mouth, holding the inhaler in its upright position and close the lips around it While breathing in deeply and slowly through the mouth, fully depress the top of the metal canister with your index finger Hold your breath as long as possible, up to 10 seconds; before breathing out, remove the inhaler from your mouth and release your finger from the canister If your physician has prescribed additional puffs, wait 1 minute, shake the inhaler again, and repeat steps listed above; replace the cap after use Cleaning To maintain proper use of this product, it is important that the mouthpiece be washed and dried thoroughly at least once a week Keeping the plastic mouthpiece clean is very important to prevent medication buildup and blockage The inhaler may cease to deliver medication if not properly cleaned and air dried thoroughly If the mouthpiece becomes blocked, washing the mouthpiece will remove the blockage Powder Metered-Dose Inhaler Does NOT require priming Do not use with a spacer or volume holding chamber Cleaning Keep clean and dry at all times Never wash or put any part of inhaler in water Routine maintenance not required If the mouthpiece needs cleaning, gently wipe with a dry cloth or tissue as needed

Salbuatmol inhaler is contraindicated in patients with a history of hypersensitivity to any of its components. Although intravenous Salbutamol, and occasionally Salbutamol tablets, is used in the management of premature labour uncomplicated by conditions such as placenta praevia, ante-partum haemorrhage or toxaemia of pregnancy, Salbutamol inhaler preparations are not appropriate for managing premature labour. Salbutamol preparation should not be used for threatened abortion during the first or second trimesters of pregnancy.

Salbutamol is a direct-acting sympathomimetic with beta-adrenergic activity and selective action on ?2 receptors, producing bronchodilating effects. It also decreases uterine contractility.

Hyperthyroidism, myocardial insufficiency, arrhythmias, susceptibility to QT-interval prolongation, HTN, DM, glaucoma, hypokalaemia, seizure disorder. Renal impairment. Elderly. Pregnancy and lactation. Monitoring Parameters Monitor BP, heart rate, electrolyte and fluid balance; glucose, lactate and K levels. Lactation: Unknown whether drug is excreted in milk; not recommended

Diuretics, corticosteroids and xanthines may augment hypokalaemia. CV effects potentiated by MAOIs, TCAs, sympathomimetics. Increases absorption of sulfamethoxazole when used together. May markedly increase heart rate and BP when used with atomoxetine. Reduces serum levels of digoxin. Hypokalaemia induced by salbutamol increases the risk of digitalis toxicity. BP should be closely monitored if linezolid is used concurrently with salbutamol.
