- Does benadryl work for pet dander? (1 answer)
hi I have been taking Benadryl or pet dander? It seemed to work well even if I only take one tablet. Does anyone also find that taking one tablet does not make you drowsy? How often should I take one tablet of Benadryl which is 25 mg? has anyone found any other allergy medication that work or pet dander? Thank you very much.
- What causes a headache only when coughing or shaking the head?
Head hurts only when shaken or I cough. I suspect benadryl or amytriptaline
- How to deal with low blood pressure caused by metformin
I was on Accupril 5 mg for more than 10 years with little or no side effects. I was diagnosed with early Type 2 diabetes and the doctor prescribed Metformin 500 mg 2 tablets a day. After about 3 months, the blood pressure was too low 88 Sistolic 45 diastolic and suffered syncope.
I reduced Accupril until I am completely off Accupril. Still the BP was too low and I then reduced Metformin to one tab a day. The BP came back and gradually became too high , i.e., 150/92. I have to put Accupril back on at 5/2 mg then 5/4 mg then finally at 5/8 mg. This seems to be optimal but the Blood Sugar is at just above 100, sometimes 106. I wish to increase Metformin back to 2 a day but afraid Bp will become too low.
Any input would be appreciated.
- Does zoloft cause ringing in the ears, like tinnitus? i've been on it for a month and noticed the ringing in the ears about a week ago, and it's just constant ringing and it's driving me insane. (1 answer)
I've been on most of the medications for more than a year and it hasn't been that bad getting used to them. But I've been on Zoloft and ambien for about a month now, and I've been noticing a lot of side effects. The one I just recently noticed and that has been driving me completely insane, is the ringing in the ears. It's been about a week now and I just don't know what to do anymore. If it is the Zoloft then I can finally just stop taking it and make this stop. If anyone has an answer or knows what to do, PLEASE help. I'm at my wits end.

- Nardil side effects and my experience taking it
I have been on many SSRI AND SNRI medications that quickly became ineffective. Was told by a doctor friend that she had been on an MAOI inhibitor for many years with good results. After going thru a horrible withdrawal detox from the SNRI I had been on and then a period of no med at all I was started on Nardil, as I needed assistance from Pfizer, the many turner in affording the medicine. My friend was on Parnate, a different brand of an MAOI.
Within days, not weeks I felt the depression lifting. It was the most dramatic and fastest response I had ever had to any antidepressant .
Then the fainting started, falls with resulting broken ribs, bedridden and alone I lost over25 lbs in two weeks. I was of normal weight for my height. After I was able to function again, I noticed that my legs were very weak. We cut my dosage from 3 pills daily to 2. That seemed to have stopped the faint spells. However I still had/have low blood pressure that I monitor at home. My Systolic BP was usually in the 70's and 80's. One of the lowest was shocking to me. It was 52/27.
My son is a hospital RN and said they would never discharge a patient with Bp that low.
He was very worried about me as I live alone. I fainted twice after climbing the 13 stairs to my bedroom. The first fall was very bad as I was unconscious and my ribs were severely injured/fractured completely around the front and back and was in terrific pain. I took to my bed and did not seek medical attn. my last ambulance ride to the hospital a mile from my house cost $1000 and since I have no income or relatives/friends to call for help, I just lay in bed I awful pain that was woes when I tried to get out of bed. Thus I lost 25 lbs of muscle, since I had very little body fat.
It has been two months since that fall and still have one area of pain in the front left ribs and a swollen spleen. The doctor gave me no additional meds and just said to give my body more time to heal. So once again was changed to 2 pills daily instead of 3. The hypotension and fainting got better. But I am now left with very weak legs and fall easily and frequently. Guess I lost a lot of muscle mass with the weight loss. However after a lifetime of depression, Nardil works wonderfully for that which had been long-standing and severe for so many years. People noticed the change in me shortly after starting the Nardil. But I am stubborn about going off it despite all the side effects because it works so much better than any of the many others I had been put on over the years.
I am soon going to start doing leg exercises with ankle weights, starting with light weights are first and gradually increasing the weight as I hopefully rebuild my muscles and strength.
Also my vision has gotten blurry and I feel slightly retarded after the weeks in bed when I was breathing very shallowly due to the broken ribs and my brain was deprived of adequate oxygen.
Prior to all this I had an IQ of 140. If they tested me now, I know I would be way down from that. Also doing lung/breathing exercises to expand my lungs so I can take in more air with each breath.
So that is my story of Nardil, hypotension, and depression. I had to really suffer to remain on this med that worked so magically for me after so many failures. It meant that much to me to not be crippled by depression.

- Had nms in 2005, will trileptal increase chance of recurrence?
In 2005 I had NMS, which was not detected by my drs for 4 months. I'd been on Lexapro & Seroquel for 2 yrs, but was weaned from Lexapro & placed on Lamictal 3/05. Began getting low-grade fevers, which I was told were not caused by the Lamictal. I quit taking it anyway, fevers (along with uncontrollable shivering) continued & got higher. By 5/05 my temps were reaching 105 deg F. Husband said I became combative, refused to go to hospital. Early June/05 he came home to find me wrapped in blankets, with a temp over 105 F. He tried to place me in a tub of cold water, said I was rigid & screamed when he tried to move me. I was in the tub, speaking "in tongues" (his description, I have no memory of this). He called 911, took me to hospital. I woke, no idea where I was or why. After a lumbar puncture & 2 days in ICU I went home. The fevers continued...2 weeks later he came home to find me wrapped in sheets, towels, blankets, with the heat on full (it was in the 90's outside) he called ambulance again. I awoke to find myself under an ice blanket with nurses pushing large vials of dantrolene into both arms, several liters. Another LP, a stint in ICU...this time they told me it was NMS. The dr who dxd me said he was surprised I was alive, & not a vegetable, as my temp had peaked at 109 deg F. I suffered brain damage; short-term memory loss, brain can't control my body temp, my blood pressure went up. An arteriogram showed completely healthy heart & arteries, no plaque at all. I lost all body fat as well as some muscle mass. The fevers continued even after stopping the Seroquel. I visited my PCP for a checkup in 9/05, temp was normal. I started shuddering, my temp went up a full degree every 5 minutes. PCP admitted me to ER, my heart rate was over 272 B/M; they stopped my heart 3 times to "reset" it, which didn't work. I spent 3 days in hospital. Several months later my P doc tried me on Lamictal alone; I got Stevens-Johnson syndrome. I stopped the drug as soon as the signs appeared. I've been untreated, except for Neurontin & Primidone, until my manic episodes became unlivable. 3 weeks ago I went 8 days with no sleep, became psychotic. My P doc gave me Trileptal, which has evened my moods, but I've been getting low-grade fevers (highest was 103.6). Would having had NMS in the past make me more prone to falling to it again with the Trileptal? It's the only new med I've taken in over a year.
