Coupons for Singulair

Singulair is the brand name for the generic drug montelukast. It is a prescription drug used in the treatment of asthma in children and adults. The medication is available as a tablet, chewable tablet, and oral granules. Singulair doesn't work rapidly enough for the treatment of an acute asthma attack. Instead, it is used as a preventative.

How Singulair Works

Singulair is in a class of drugs known as leukotriene inhibitors. Leukotrienes are substances released by the body in response to irritation by allergens. They cause constriction of the muscles in the airways and swelling of tissue in the lungs. These conditions present themselves as the classic wheezing and shortness of breath seen in asthma attacks. Singulair inhibits the release of leukotrienes so there is less respiratory irritation.

How To Take Singulair

Singulair should only be taken when prescribed by a physician. The oral granules can be mixed with liquid or food for ease of administration. The granules can be mixed with formula or breast milk when giving the drug to babies. Once the granules have been mixed with food or liquid, they must be consumed within 15 minutes. The chewable tablets should be thoroughly chewed before swallowing and the regular tablets should be swallowed whole. The medication is usually taken once daily in the evenings.

Singulair works over time and must be taken on a regular schedule to be effective. It can take up to six weeks to see results from this medication. Teens and adults who suffer from exercise induced bronchospasm may be able to prevent attacks by taking a dose of Singulair two hours before working out. This dose is taken in place of the regular evening dose and not in addition to it.

Side Effects And Precautions

Serious side effects are not common with Singulair but there is always a risk involved with taking any medication. Symptoms of an allergic reaction require immediate medical attention. These include rash, itching, swelling of the tongue or throat, trouble breathing, and severe dizziness. Other possible side effects that require evaluation by a physician include aggression, agitation, insomnia, depression, sleep walking, hallucinations, abnormal dreams, numbness, tingling, tremors, worsening asthma, easy bruising, unusual bleeding, shooting pains, muscle weakness, and thoughts of suicide or thoughts of harming others. Less serious side effects can include headache, stomachache, nausea, diarrhea, fatigue, tooth pain, sore throat, cough, fever, and mild rash.

Some chronic medical conditions such as liver disease may require careful evaluation by a medical professional before prescribing Singulair. In addition, some medications such as phenobarbital and rifampin should be avoided or carefully monitored when taking Singulair. The prescribing doctor should also be informed of any other prescription drugs, supplements, and vitamins that are being taken before starting the medication.

Overdose Information

Overdoses of Singulair and suspected overdoses should be treated at once by contacting an emergency room or a poison control center. To prevent an overdose, the medication should be taken exactly as prescribed, and not more often. Do not increase the frequency or dose without consulting a physician. If a dose is missed, skip it and resume normal dosing schedule when the next dose is due. Take only one dose within a 24 hour period, even when taking Singulair for exercise induced bronchospams. Symptoms of Singulair overdose include severe thirst, vomiting, stomach pain, drowsiness, or inability to sit still.
