Can long-term use of Singulair and Levocetirizine (for chronic allergies) cause side effects: liver damage, low sex drive/libido? Can't use sprays.

Not really: but you need to keep the follow up with your doctor, both drugs aren't known for the side effects you noted, Singular may cause liver problems, but not related to long term use rather due to a reaction by some patients even after few doses, rare. If you have chronic allergies,you need an allergist evaluation with regular follow up as you may need different approach,check aaaai.org for an allergist ...Read more

What is the toxicity of advair and singulair (montelukast) usage in long term asthma treatment?

What is the toxicity of advair and singulair (montelukast) usage in long term asthma treatment?

Non-toxic but...: While every medication has benefits and side effects, the benefits of advair (combination inhaler) and singulair (montelukast) (leukotriene tablet) outweigh the risks when treating serious conditions such as asthma. Long term studies have shown a small affect on rate of growth in pediatric patients for medications containing steroids (advair) but not singulair (montelukast). An allergist can review these issues in detail. ...Read more

Is Singulair safe to take long-term? Can it cause Churg-Strauss syndrome? On and off it for 3 years, only drug that clears up mucus in nose and throat

Is Singulair safe to take long-term? Can it cause Churg-Strauss syndrome? On and off it for 3 years, only drug that clears up mucus in nose and throat

Considered safe: All medications have potential side effects, some of them severe, and Singulair is no exception. Churg-Strauss is among those possible effects. However, Singulair is considered on the safer end of the spectrum. Naturally, the longer you are on a medication, the more likely it is that a side effect would occur, but there are no specific recommendations against long-term use of Singulair. ...Read more

I took singulair (montelukast) for the third day now. It seems to be helping but I had stomach pain last night. Will this side effect subside? About how long do side effects last? Or should I quit taking it?

I took singulair (montelukast) for the third day now. It seems to be helping but I had stomach pain last night. Will this side effect subside? About how long do side effects last? Or should I quit taking it?

Singulair (montelukast): In my experience singulair (montelukast) has been very well tolerated and I'm unaware of it being tough on the stomach. You could retry taking it when your stomach is back to normal to see whether the same discomfort recurs. If you're taking other medications like antibiotics, mucus looseners, cough syrups or bronchodilators, perhaps one of them was responsible for your stomach distress. ...Read more

Difficult to answer: Unlike rescue inhalers which work very quickly, oral drugs like singulair (montelukast) do take awhile.

Post-nasal drip?: When treating a chronic cough, you must treat every possible contributor to the cough or it won't resolve. Post-nasal drip or any sinus condition can result in bronchospasm and, thus, the cough. Perhaps you need to add a nasal steroid spray to your regimen in addition to a steroid inhaler and your other meds. You may need a very slow steroid taper to get to the lowest possible effective dose. ...Read more

Assistance program: There is another leukotriene pathway medication called zileuton cr, but it is brand-name only and requires monitoring liver function periodically. However, you should ask your doctor about the patient assistance programs through the drug manufacturers that make singulair (montelukast) and/or zileuton. They may help pay for part or all of the cost of the medication depending on your level of need. ...Read more
