Serevent (salmeterol) is a long-acting bronchodilator mainly used to prevent the symptoms of a bronchospasm for people with COPD (chronic obstructive pulmonary disease) or asthma patients. Serevent inhaler may be used to prevent the same symptoms from surfacing during physical exercise - the effect of this medication lasts for up to 12 hours, making it less necessary to use short acting bronchodilators to relieve acute symptoms. However, Serevent by itself is not suited to relieve acute symptoms if such a reaction is taking place. The onset of positive effects of the active ingredient salmeterol (long-acting beta 2 agonist) usually takes up to one hour of time, which is completely unsuited in treatment of an imminent bronchospasm. If you buy Serevent online, remember that it should be used only as a preventer. In case you experience a sudden worsening of symptoms during the treatment, make sure you have a fast-acting "rescue" bronchodilator close by.
The Reason of Using Serevent
Serevent inhaler is usually prescribed as means of additional treatment of symptoms of COPD or asthma, when short-acting bronchodilators (albuterol, salbutamol, terbutaline) and/or steroids alone are not enough to control the condition. Because the effects of Serevent last for an extended period of time, it is better suited to patients who have trouble sleeping because of breathing problems, as well as people who find themselves very frequently in need of using a bronchodilator.
Ideally, during and after the treatment with Serevent, the patient will receive at least several of the following positive effects:
- Comfortable, normal breathing, especially at night;
- Reduced necessity of short-acting bronchodilator use;
- Absence of difficulty performing basic physical activities or exercise;
- Reduced number of episodes of breathlessness and shortness of breath;
- Significant reduction in the number of bronchospasms and asthma attacks.
Serevent Restrictions and Warnings
As mentioned earlier, Serevent should only be applied when other methods of treatment prove ineffective or lacking in effectiveness, and there is a good reason for that. This medication may consist within the same drug group as other bronchodilators, but it carries a much more significant risk to the patient's health when used.
There are several precautions you should be aware of before using Serevent:
- Serevent may cause an increase in blood pressure (hypertension) in some patients, resulting in elevated risk of heart and blood-pressure related problems. It is essential to consult your doctor before starting Serevent if you already have problems with your heart, blood pressure, blood circulation, or have a condition that may worsen due to changes in blood pressure (e.g. epilepsy).
- Patients who suffer from an overly active thyroid gland function (a condition known as hyperthyroidism) and thus have a greatly stimulated metabolism rate should use Serevent with caution, as it may further affect their metabolism and cause unintended side effects.
- People suffering from a form of diabetes should use Serevent with care - several studies show that extended use of this drug may worsen the symptoms of the disease. Consult your doctor for the possible advantages and disadvantages to using this drug in your condition.
- Children under the age of 4 should not use this medication.
Naturally, people who are allergic to salmeterol should not use Serevent. Allergies to other components within the inhaler (preservatives, propellant and others) may also prove dangerous. If you have any specific or rare allergies to medications, you may inquire the pharmacist present at the store where you buy Serevent online of the full formulation of this drug.
