The medication is used with caution in the following cases:
- heart diseases (such as tachyarrhythmias, acute and chronic myocarditis, defect, ischemia, severe failure);
- arterial hypertension;
- diabetes mellitus;
- predisposition to epileptic manifestations;
- a history of renal or hepatic failure.
The period of pregnancy and breastfeeding require especially careful therapy with Proventil. Use is contraindicated if you are using non-selective β-blockers.
How to use Proventil?
The drug is used exclusively for inhalation, during which the medicine is inhaled through the mouth. For small children, medication is administered using a special device (called a spacer), which has a face mask. When the inhaler is used for the first time or the last use of the drug was more than 5 days ago, it is recommended to remove the cap, shake the can and make 2 sprays of the drug in the air.
- Remove the cap;
- Check all parts of the can and mouthpiece to make sure there are no foreign objects;
- Shake the inhaler (this will mix its contents evenly);
- Hold the balloon upside down, exhale as much as possible;
- Place the mouthpiece in your mouth and cover it with your lips, but not touch it with your teeth;
- During a deep breath, press on the top of the cartridge so that one dose of the medicine enters the respiratory tract;
- Hold your breath;
- Remove the mouthpiece from your mouth;
- If another dose is required, repeat all steps after 30 seconds;
- Close the tip with the cap.
What is the right dosage of Proventil?
A single dose for bronchospasm is 100 μg, that is, one dose of the medicine. If required, a single dosage can be doubled, and the maximum frequency of drug use per day is 4 times. If the inhaler is used to prevent bronchospasm, then the drug must be inhaled 10-15 minutes before physical exertion or the influence of another provoking factor. Usually, one dose is enough, that is, 100 μg, but, if necessary, it can be increased to 200 μg. If the medication is prescribed as part of maintenance treatment, then you will need to do inhalation 4 times a day, and the dosage per application will be 100-200 μg.
Can I overdose on this medicine?
Inhaling a high dose of Ventolin can cause the following symptoms:
- decreased blood pressure;
- rapid pulse;
- trembling muscles;
A very high dose of the drug provokes hypokalemia, as well as metabolic acidosis.
Can I take other drugs with Proventil?
This medicine is not used together with non-selective β-adrenergic receptor blockers (for example, Propranolol), Theophylline and other xanthines, as this threatens the patient with tachyarrhythmia. Do not combine it with drugs used as inhalation anesthesia, for example, Levodopa as their combination can cause severe ventricular arrhythmia. The combined use of albuterol with an anticholinergic drug is unacceptable since such a combination leads to increased intraocular pressure.
The combination of albuterol with diuretics and glucocorticosteroids for inhalation (hormonal drugs such as Atrovent, Pulmicort) leads to an increase in the hypokalemic effect of albuterol.
This medication can be used simultaneously with monoamine oxidase inhibitors.
In the treatment of bronchitis, the medicine is combined with antibiotics, antiviral drugs, expectorant drugs and vitamin complexes.
