  Generic Medication guide:

What is Serevent and when is it appointed?

The medication known as Serevent is made by GlaxoSmithKline. The ingredient thanks to which the clinical effect of the medication is achieved is Salmeterol. It was first released onto the market in 1990 and now can be made by various drug manufacturers since no company holds an exclusive patent for its production. The substance sold under the less known name can be found it you look for generic Serevent. It isn’t the name you can find on the package of the product but rather a general term that helps people to find cheaper versions then the medications they have been prescribed.

Salmeterol is a bronchodilator with anti-asthmatic activity. The effect of this substance is due to the selective stimulation of beta 1 adrenergic receptors, relaxation of the bronchi, prevention of an allergic response, suppression of the inflammation mediators’ release, and the overall suppression of the inflammation in the lungs.

You can buy Serevent if you suffer from:
- Asthma;
- Chronic obstructive pulmonary disease;
- Chronic bronchitis.

The inhaler has to be used regularly as an additional therapy of reversible obstruction of the airways in asthma, including night asthma attacks, symptoms of asthma that are not sufficiently controlled by the use of inhaled corticosteroids, and prevention of asthma attacks due to physical activity.

For the same purposes, a variety of medical products can be used so you have to follow your therapist’s recommendations in order to maximally benefit from the therapy.

Serevent contraindications for use

The use of the inhaler is strictly prohibited in intolerance of its components and for children aged less than four years.

The use is possible but only cautious and if a doctor approves in the presence of:
- Hyperfunction of the thyroid gland;
- Arrhythmia;
- Ischemic heart disease;
- Uncontrolled arterial hypertension;
- Low oxygen content in the body or individual organs and tissues;
- Pheochromocytoma (hormonal tumor);
- Pregnancy and lactation;
- Old age.

If you have any cut or chronic conditions not listed here, you should still inform your doctor about them so he or she would be able to correctly assess your condition and if necessary adjust the therapy.

Serevent dosing

You can buy generic Serevent from our online pharmacy without having Rx but it would be wiser to get the Rx and precise instructions on how to use the inhaler from your doctor before you get the medication and start the therapy. Here you can find the general instructions but still, an individually chosen dosages and control over the symptoms are preferable.

The inhaler must be used regularly even in the absence of asthma attacks. The complete therapeutic effect is achieved in several times of medication use. Since there is a risk of adverse effects occurrence in the elevation of the medication dosage, they can be increased only at the doctor’s discretion and under supervision.

Recommended dosages for asthma for adult and children over 12 years:
- Two inhalations two times a day. In the severe obstruction of the airways, the dosage can be raised to four inhalations made two times a day.

Recommended dosages for asthma for children between 4 and 12 years:
-  Two inhalations two times a day. It is the maximum daily dosage that must not be exceeded.

Recommended dosages for the chronic obstructive pulmonary disease for adult and children over 12 years:
- Two inhalations two times a day.

For this condition, the formulation is not appointed for younger children.

When you buy Salmeterol, in the package insert you will find the instructions on how to use and maintain the device properly. However, it is advised to get instructed by a respiratory specialist and actualize the inhaler before them so a specialist would be able to assess whether you use it correctly or not.

Special patients groups

There is no need to adjust the dosages for patients over 65 years or individuals with kidney failure. There is no data on the safety and dosage adjustments for individuals with liver failure.

Overdose with Serevent

An overdose with the inhaler is manifested in the same symptoms as an overdose with any other beta-2 receptors stimulants such as tremor, headache, dizziness, rapid heartbeat, elevation of the blood pressure and lowering of potassium level.

In case the symptoms are severe, a patient needs symptomatic treatment such as lowering of the blood pressure, the intake of medications that normalize the heart rate, and so on.

Adverse reactions

- Tachycardia, elevation of the blood pressure, violation of the heart rhythm;
- Diarrhea, pain in the abdomen, nausea, gastroenteritis, irritated oral and throat mucosa;
- Headache, dizziness, tremor, nervousness, agitation, insomnia, and taste perversion;
- Paradoxical bronchospasm, coughing, allergic reactions of different severity.

In case of an allergy associated with the inhaler use, it must not be used further and a doctor must be consulted.

Interactions with other substances

When you buy Salmeterol, make sure not to use it along with the incompatible medicines. For instance, when using the inhaler it is recommended to avoid using selective and non-selective beta-blockers. Other significant interactions are:
- The use of the inhaler can cause severe hypokalemia (low potassium). The risk of this adverse effect is increased by the use of xanthines, steroids, and diuretics.
- Ketoconazole used along the inhaler causes the substantial increase of the latter in the blood which can lead to the QT interval extension (heart dysfunction). The similar risk is expected in the combination of the inhaler with other potent inhibitors of the CYP3A4 enzyme.
- The simultaneous use of erythromycin with the inhaler can cause an elevation of Salmeterol level in the blood. However, it is not a contraindicated combination since no severe adverse reactions were recorded in relation to such therapy.

Adverse reactions associated with Serevent use occurred in ≥ 3 of adult and adolescent patients with asthma

Adverse reaction

Albuterol Inhalation Aerosol 180 mcg 4 Times Daily

The treatment of asthma must be performed taking into account the severity of the disease and all other related factors.

Salmeterol is not the first-line therapy. It cannot replace the use of oral or inhaled glucocorticoids so it has to be used as an additional therapy to them. Patients must not cease or lower the dosage of steroids without a doctor’s approval even if the use of Salmeterol improves the symptoms.

The inhaler is not used for the acute asthma episodes. A patient must always have at hand quickly-acting bronchodilators that are aimed for acute asthma attacks.
If during the therapy with Serevent a patient notices a more frequent need of the use of quick-acting bronchodilators, it can indicate the worsening of the condition that requires the change of the therapy.
The inhaler can be introduced to the therapy at a time of remission and not the aggravation of the condition even though it can improve it.
Unless a patient develops severe adverse effects as a response to the use of Serevent, the therapy must be continued the gradual reduction of the dosage instead of abrupt cessation in case the use of Serevent must be eventually discontinued.
