What is a generic medication?
Generic medications are significantly discounted copies of brand name medication that have the same active ingredients, intended use, dosage, side effects, effects, and route of administration as the original brand name medication. In other words, generic medications have the same pharmacological effects as their brand-name counterparts. Over half of all prescribed medications are for generic medications.

Montelukast is used to control and prevent symptoms caused by asthma (such as wheezing and shortness of breath). It is also used before exercise to prevent breathing problems during exercise (bronchospasm). Singulair can help decrease the number of times you need to use your quick relief inhaler. Montelukast is also used to relieve symptoms of hay fever and allergic rhinitis (such as sneezing, stuffy/runny/itchy nose). Since there are other allergy medications that may be safer (, Singulair should be used for this condition only when you cannot take other allergy medications or they do not work well. Singulair must be used regularly to be effective. It does not work right away and should not be used to relieve sudden asthma attacks or breathing problems. If an asthma attack or sudden shortness of breath occurs, use your quick-relief inhaler as prescribed. Singulair works by blocking certain natural substances (leukotrienes) that may cause or worsen asthma and allergies. It helps make breathing easier by reducing swelling (inflammation) in the airways.
Singulair may rarely cause serious mental/mood changes. These effects may occur even after the medication has been stopped. Tell your doctor right away if you or a caregiver/family member notice symptoms such as agitation, anxiety, abnormal dreams, depression, memory/attention problems, hallucinations, trouble sleeping, or changes in behavior (such as aggression, hostility, restlessness, sleepwalking, suicidal thoughts/attempts). Talk to your doctor about the risks and benefits of Singulair.
How to Use Singulair
Read the Medication Guide provided by your pharmacist before you start taking montelukast and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take Singulair by mouth with or without food as directed by your doctor. The Dosage of Singulair is based on your age and medical condition. If you are using the chewable tablets, chew them thoroughly before swallowing. If your child cannot safely chew and swallow them, consult the doctor or pharmacist for advice. Take Singulair at the same time each day. If you are taking Singulair for asthma or for both asthma and allergies, take your dose in the evening. If you are taking montelukast to prevent only allergies, take your dose either in the morning or the evening. If you are taking Singulair to prevent breathing problems during exercise, take your dose at least 2 hours before exercise. Do not take more than one dose in 24 hours. Do not take a dose before exercise if you are already taking Singulair daily for asthma or allergies. Doing so may increase the risk of side effects. Do not increase or decrease your dose or stop using Singulair without consulting your doctor. Continue to use Singulair regularly to keep your asthma under control, even during sudden asthma attacks or periods when you have no asthma symptoms. Continue to also take other medications for asthma as directed by your doctor. Singulair works over time and is not meant to relieve sudden attacks of asthma. Therefore, if an asthma attack or other breathing problem occurs, use your quick-relief inhaler as prescribed. You should always have a quick-relief inhaler with you. Consult your doctor or pharmacist for more details. Get medical help right away if your asthma symptoms worsen and your quick-relief inhaler is not helping. Tell your doctor promptly if asthma symptoms, breathing problems, allergy symptoms, number of times you use your rescue inhaler persist or worsen.
Before taking montelukast, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. Singulair may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details. Before using Singulair, tell your doctor or pharmacist your medical history,liver disease, mental/mood problems (such as anxiety, depression, thoughts of suicide). Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). The chewable tablets may contain aspartame. If you have phenylketonuria (PKU) or any other condition that requires you to limit/avoid aspartame (or phenylalanine) in your diet, ask your doctor or pharmacist about using Singulair safely. During pregnancy, Singulair should be used only when clearly needed. Discuss the risks and benefits with your doctor. Singulair passes into breast milk. Consult your doctor before breast-feeding.
If you miss a dose of Singulair, skip the missed dose. Take your next dose at the regular time. Do not double the dose to catch up. Do not take more than 1 dose in 24 hours.
Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.
Singulair Side Effects
What are Singulair side effects?
Side effects are physical, mental or emotional symptoms which occur in addition to or outside of the desired effect of a therapeutic treatment such as an over-the-counter or prescribed drug or medication. Side effects from Singulair may occur at the beginning or at the end of treatment and may also depend on the length of time an individual remains on the treatment. Side effects, also known as adverse effects, are generally more likely to occur when starting treatment. Individuals may also experience side effects from Singulair as a result of an interaction with other medications.
Side Effects of Singulair
The side effects of Singulair may vary in number and intensity for many different reasons. Factors such as age, weight, gender and ethnicity may influence the side effects of Singulair. Also, an individual’s state of general physical health and seriousness of the disease or illness as well as an increase or decrease in dosage may lead to side effects. Further, side effects from Singulair may also occur as a result of an interaction with certain herbal supplements, foods or drinks.
Prescription drug side effects can be serious and may cause patients to stop the treatment. However, when side effects from the use of a prescription drug, such as Singulair, do occur a patient should consult their physician. A physician may prescribe an additional treatment in order to control the symptoms or an adjustment in the dosage may be made. In addition, changes to diet, exercise or other lifestyle activities may help to lessen the side effects of Singulair.
