Zyrtec Feeling Abnormal Causes and Reviews


Chiari malformations (CMs) are structural defects in the cerebellum. The cerebellum is the part of the brain that controls balance. With CM, brain tissue extends into the spinal canal. It can happen when part of the skull is too small, which pushes the brain tissue down. There are several types of CM. One type often happens in children who have neural tube defects. Some types cause no symptoms and don't need treatment. If you have symptoms, they may include

  • Neck pain
  • Balance problems
  • Numbness or other abnormal feelings in the arms or legs
  • Dizziness
  • Vision problems
  • Difficulty swallowing
  • Poor hand coordination

Doctors diagnose CM using imaging tests. Medicines may ease some symptoms, such as pain. Surgery is the only treatment available to correct or stop the progression of nerve damage.

Zyrtec Feeling Abnormal Reviews

Fri, 21 May 2010

I took one dose and experienced a bout of pancreatitis. I suffer from chronic pancreatitis and know what most of my "triggers" are.....never thought a simple allergy medication would cause such a problem, I think I would rather suffer allergies than risk pancreatitis.

Sat, 05 Nov 2011

Started on Zyrtec on the suggestion of my dermatologist for treatment of hives. Rash that resulted from the Zyrtec a MILLION times worse than the original hives. Had the same reaction to Seldane.

Tue, 09 Feb 2010

I have Type 2 Diabetes, when taking my level in the morning I noticed my level was elevated, and the only thing I had ingested was a Zyrtec pill about 2 hours prior? Could the pill be the cause?

Wed, 03 Dec 2008
Does Zyrtec inrease blood sugar levels? I have been taking 10m a day for 10 days and have notices symptoms of high blood sugar, when tested it was in the high 100's. Has anyone heard of this side effect?
Sat, 13 Aug 2011
I have had and am having a bad reaction to Zyrtec. My eyes are inflamed and my throat is sore. Lips are swollen. My tongue is white. I will be forced to go to the Emergency at the hospital.
Sun, 28 Mar 2010
I took Zyrtec for a week and while it does solve my allergy issues, it makes me a raving lunatic. Severe aggression, mood swings, and nightmares are the norm for me n this medicine. I would not recommend it if you are taking any anti anxiety or anti depressants.
