Singulair and lupus

October 22, 1998 I had resp. failure (with intubation). My new pulmonary doctor put me on Singulair 10 mg once a day, a few weeks after. Within time, I started to have numbing and tingling in my face, arms, and legs. March of 1999 the symptoms worsened and started causing pressure in my face, arms, and legs, and anxiety started to kick in. I was told I had neuropathy and to take mobic. Symptoms getting worse, and went to a rheumatologist in June 1999, and he was suspect of singulair. The doctor thought that what I was experiencing was due to the singulair. He (the rheumatologist) discussed this with the pulmonary doctor and the pulmonary doctor did not believe this to be the case. Not forgetting, in March of 1999, I had a ct of the sinus area, and low and behold 1/3 of the cavity was and probably still is full of polyps.

As time went on, symptoms getting worse, and not one bloody doctor could figure out why I was feeling this way. In addition, at times, I was put on steroids for my asthma (not including my inhalers).

Two years ago, my body went into shock, leaving my left side very different than my right side. Affecting: my head, my face, my eye, my ear, my esophogus, my lungs, my arm, my leg.

I have been depressed and anxious not knowing what the heck was going on with me.

Recently ruled out thyroid, and lupus, and possibly ms.

Last weekend, I reviewed the letter from the rheumatologist (dated 1999) and the ct report from March 1999 (regarding the sinus/ polyps) and made copies to present to a pulmonary doctor that I have recently been seeing.

This past Monday the 10th, I had my appt with him. He knew of my situation from the last few visits (in addition, I had met him this past March for a pulmonary rehab program, and thought he seemed to be knowledgeable and compassionate). While waiting for him to enter the exam room, he had read those reports before entering.

The doctor looked at my hands (red as a beet and swollen) and said "You have Churg-Strauss Syndrome, and get off the singulair."

I had done my homework from a few weeks ago, where I looked up untreated polyps.
Untreated polyps, can turn into vasculitis. There are many types of vasculitis, to include Churg-Strauss Syndrome.

I then cross ref CSS and singulair, and low and behold, BINGO!

I have been suffering for ten years, physically and emotionally because of this drug!

There is also recent updates from the fda (fda.gov) regarding singulair, of which most recently includes anxiety and depression.

I suggest before taking singulair, be aware of the side effects. As soon as a side effect comes up, contact your doctor. Also, be aware of existing conditions (like me, sinus problems and asthma) for this could lead to churg-strauss syndrome.

This info is indicated on the actual disclosure (the paper insert that indicates studies, side effects, etc...) not the handout that is given with the drug.

By the way, I am now working with a new rheumatologist in Los Angeles (Cedar-Sinai affiliated) and a new neurologist.

I started full body internal itching after taking 10 days of Singulair. The physician that prescribed it said it couldn't cause itching. My new doctor tested for Lupus, I have an autoimmune disorder called Churg Strauss. After undergoing several steroid treatments and 3 days of IV Prednisone I got some relief. This has been going on for 6 months now. The itching becomes severe enough to make me want to commit suicide. Luckily it is pretty controlled by taking nightly doses of Atarax along with Periactin. Thank God I found a doctor who cared enough to search out the symptoms and help me get thru day by day.

Hi,

I just found this site, as I am looking for an explanation for the extreme joint pain that I am having, along with swollen ankles/feet. I have been dealing with some type of chronic contact dermatitis that no one has been able to solve, since last July. I have been on numerous steroids, then on Cyclosporine, for several months, which can play havoc with your kidneys. I also started taking Singulair for the itching, which is one of the few things that has really helped. Since November, I was taking Singulair on and off. But, as I recall, I began taking it daily since around late January. Around late February, I began having joint pain, which still continues, and lately, is becoming excruciating! When it first began, I blamed it on the Cyclosporine and kidney breakdown. But, since I have been off that, the pain has continued to worsen. Then I thought it may have something to do with the Doxepin, which I also take at night for the itching. I stopped taking that two nights ago, but the pain continues to worsen.

Now, from what I am reading, these blogs make me believe it could be the Singulair. Can anyone tell me how long it takes for the pain to go away once you stop taking the Singulair????? I will gladly stop taking it if this pain will go away. In fact I will be thrilled, because I was suppose to begin testing next weak for possible Lupus, because it doesn't seem that the Physicians who prescribe Singulair, are well aware of these issues.

I would appreciate anyone who can give information as to how long it takes for the side effects to subside. Thank you!!!

An element of the side effects of Singulair that are listed here are musculo-skeletal symptoms. Quinolones such as levaquin are known to cause those issues. Singulair is a quinoline, while not the exact same category, their roots are similar. It makes the possibility that the symptoms have a common cause worth pursuing.

Here is an example of some poor rats in Tokyo that were selected to prove that the symptoms in humans were real. Maybe we should tell the levaquin board that at least some of their problems have been known since 1997.

Toxic effects of quinolone antibacterial agents on the musculoskeletal system in juvenile rats.Kashida Y, Kato M.

Quinolone antibacterial agents have adverse effects on the musculoskeletal system in humans, consisting mainly of myalgia and arthralgia, and additionally of tendon disorders and rhabdomyolysis. The present study was conducted to examine the toxic effects of quinolones on the musculoskeletal system in juvenile rats using light microscopy, 5-bromo-2'-deoxyuridine (BrdU) immunohistochemistry and electron microscopy. Single oral administration of 900 mg/kg pefloxacin (PFLX) or levofloxacin (LVFX) was found to induce lesions in the muscle + fascia, tendon + sheath, and synovial membrane, in addition to articular cartilage in the fore- and hindlimbs. Articular cartilage lesions were not necessarily associated with changes in the muscle, tendon, and synovial membrane, or the reverse. Among all lesions, the ankle and elbow showed the highest incidence and severity. Changes were more severe in the PFLX than in the LVFX group. Lesions in the muscle + fascia, tendon + sheath, and synovial membrane were similar and characterized by edema and increased number of mononuclear cells, many of which were positively stained with BrdU, as well as vascular endothelial cells in the Achilles tendon sheath and synovial membrane in the ankle. Electron microscopic examination revealed an increased number of fibroblasts and macrophages and collagen deposition in the matrix of the synovial membrane and tendon sheath. Capillary endothelial cells were hypertrophied, increased in number, and stratified. These results suggest that quinolones have toxic potentials in the muscle, tendon, and synovial membrane in addition to articular cartilage, and that local vascular hyperpermeability may contribute to the development of these lesions.

I am 40-years-old and took Singulair for about two months. I first took it for about two weeks and got horrible symptoms and then stopped for a week and then tried it again for about a month. Never again will I put Singulair into my body. My symptoms were chronic and severe muscle cramps and twitching, restless legs, body aches, numbness, tingling, hair loss, weight gain, and skin changes (urticaria and angioedema). I also used to suffer from menorrhagia to where now I barely get a cycle. I cannot blame Singulair for the headaches/migraines because I have been a headache/migraine suffering for many years.

When I first stopped taking Singulair the symptoms calm down. But since then they have come back with a vengence. I have been to several specialty doctors (family doctor first, endocrinologist, neurologist, allergist and rheumatologist). Now please let me defend myself by saying I see my family doctor and gynecologist yearly for a physical and also when I am sick and I have always been basically a very healthy, and slender woman with thick hair. I was on no other medications other than ibuprofen and acetaminophen for the headaches/migraines. What they have found so far is that I have secondary autoimmune hypothyroidism (only my TPO antibody and thryoglobulin are extremely elevated, but my TSH, T3 and T4 are completely normal), and allergies to everything outside (no food or pet allergies) and idiopathic lupus (because my skin has developed urticaria and angioedema).

I am going for an EMG and MRI of the brain in one week because they are trying to rule out MS. They have been saying that my symptoms look like MS or lupus. They have ruled out lupus because my blood tests do not show lupus only my skin is acting like lupus. My allergist put me on doxepin for my skin and twitching symptoms. This medication has helped my skin and slowed down the twitching.

I am not trying to blame Singulair, but it is very strange that I was a basically healthy person with some outdoor allergies and mild asthma. I would get pneumonia once a year also (always around the holidays). Now, I feel like crap since taking Singulair. My legs are the worst of all the symptoms along with the constant twitch under my right eye. This can drive a person insane, especially when you are trying to relax and your body cannot.

Thanks for listening,
