How Should This Medicine Be Used

When montelukast is used to treat asthma, it should be taken in the evening.

Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take montelukast exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

What Is Singulair How Does It Work
Singulair, or montelukast, is a leukotriene receptor antagonist .
Leukotrienes are released by the immune system in response to allergens, such as pollen, and promote inflammation, bronchoconstriction , breathing difficulties, and other allergy symptoms.
The active ingredient, montelukast, in leukotriene receptor antagonists like Singulair binds to these receptors and opposes their function.
Singulair is usually used to prevent asthma attacks and treat seasonal allergies. Singulair isnt effective for acute asthma attacks or sudden, extreme allergic reactions. Instead, its commonly used long-term for maintenance purposes and is usually safe for extended, regular use.

Asthmatic women treated with MS + ICS showed a better control of symptoms compared with men treated with the same dose and therapeutic approach . The higher effectiveness of MS + ICS in women vs. men is highlighted by the Delta Percentage , which confirms the achievement of a better control of symptoms in women respect to men .

Can Montelukast Cause Problems
Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains the most common ones associated with montelukast. You will find a full list in the manufacturer’s information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.
|Common montelukast side-effects||What can I do if I experience this?|
|Tummy pain, feeling sick , diarrhoea||Speak with your doctor if this continues|
|Headache||Drink plenty of water and ask your pharmacist to recommend a suitable painkiller. If the headaches continue, let your doctor know|
|Throat and chest infections, high temperature , skin rash||If troublesome, speak with your doctor|
Important: if you get any of the following symptoms, please let your doctor know straightaway. These can be a sign of a very rare but serious disorder called Churg-Strauss syndrome: flu-like symptoms, tingling feelings or numbness in your arms or legs, difficulties with breathing, and skin rash.
Taking montelukast can sometimes affect your mood or behaviour, such as causing nightmares or other sleeping problems, anxiety, depression, agitation, irritability or restlessness. If you think you are being affected in this way, speak to your doctor for advice.
Safety Profile Of Montelukast
The safety profile of montelukast has been well evaluated in the many long-term studies on large groups of adult and paediatric patients, and no significant or considerable side effects have been reported . A recent review on more than 2700 children and adolescents concluded that the clinical and laboratory safety profile for montelukast was similar to that observed for placebo or active control/usual care therapies, and that the safety profile of montelukast did not change with long-term use .
Since the beginning of the use of montelukast, several case reports on the occurrence of a Churg-Strauss syndrome have been reported. These cases have been considered as being due to the loss of some masking effect of high-dose ICS or oral corticosteroids, which were reduced after the addition of montelukast, with subsequent manifestation of full clinical features of the systemic vasculitis. A report on a large number of patients with CSS has been described in a recent paper, showing that montelukast use was associated with a 4.5-fold risk of CSS onset within 3 months, although this effect might be confounded by the escalation in asthma therapy before CSS onset .
More recently, some concern was raised regarding the possibility of greater suicide rate in patients taking montelukast, but the revision of 116 clinical studies showed that the frequency of behaviour-related adverse experience and suicides in patients treated with montelukast was no different from control groups .
