Cardiac complications symptoms and conditions

I have restless legs, nightmares and weight gain. Trouble concentrating, numbness and tingling of the hands and feet, falling. I have been evaluated by a neurologist and no one has made the connection of weight gain to singulair.
Also, have high blood pressure that came on suddenly.

I have followed the South Beach diet and continued to gain. I am going off this drug and really appreciate this website.

I was on it for 2 weeks for an upper respiratory infection and I have mild asthma. I got to the point after the 2nd week I could not feel my legs, they felt detached. I cried. I thought I was water in car when I drove to a doctor appointment. I felt like I had the flu 24 hours a day. No headaches but it never touched my asthma. Two weeks of that junk then I went to a doctor who put me on my medication I took as a kid. One pill and it was over.
Sudafed in my opinion is a dangerous drug. Those side effects they list on tv are a joke. They are the tip of the ice berg.

I have been on Singular for 2 months. I have noticed dizziness and almost passing out. I thought it was my other herbal supplements, but now I am still having the feelings and I will discontinue the Singular! Today I have a headache and just don't feel right in my head, almost like double vision feeling. I'm glad I found this website. I went on Singular for dog allergies, but it is not worth feeling this way!

I am a 57 year old man, who has been suffering from asthma several years. This spring my doctor put me on Singulair as an additional medicine to my cortisone-inhalator. after one month I feel symptoms of depression an mood-changing, severe ups and downs.
AND - as an additional symptom i have partially lost my feeling in some fingertips, and now parts of my left thumb and even a feeling of "cold2, mostly in my left hand.
anyone who share that symptom?

Have been taking Singulair but not consistently. I am a middle aged overweight male, and the MD suggested that conventional antihistamines could have cardiac complications.

Tried taking singulair at night per instructions but found it interfered with sleep. Recently moved to taking it in the daytime and found it prevented me from staying awake.

A couple of near-accidents while driving.

Mood swings, apathy and hostility, and even a trace of paranoia.

Greatly reduced intellectual capacity, a very bad thing for me as a computer programming professional.

Stopped taking it a week ago and I am almost back to myself. Hope and believe I escaped long term damage. I suppose I could be an outliers but I'm basically wired pretty well and I tend to doubt it. My impression is that this drug has such severe neurological effects that it should only be prescribed, if ever, in case of extreme need.

I'll take the sniffles, thanks. Singulair made me lazy, mean and stupid. Not a good trade at all.

The idea that this stuff is being foisted on inarticulate young children horrifies me. Even as an adult it is hard to make the connection. One doesn't anticipate severe psychotropic effects from something that replaces over the counter allergy meds.

I hope I'm an outliers but I think this needs some investigation. Suicide is awful, of course, but if its incidence goes up a little, perhaps a lot of minds are being disrupted short of suicide. If so this is a catastrophe and a travesty.
