Zyrtec Product Quality Issue Causes and Reviews


We all need clean water. People need it to grow crops and to operate factories, and for drinking and recreation. Fish and wildlife depend on it to survive.

Many different pollutants can harm our rivers, streams, lakes, and oceans. The three most common are soil, nutrients, and bacteria. Rain washes soil into streams and rivers. The soil can kill tiny animals and fish eggs. It can clog the gills of fish and block light, causing plants to die. Nutrients, often from fertilizers, cause problems in lakes, ponds, and reservoirs. Nitrogen and phosphorus make algae grow and can turn water green. Bacteria, often from sewage spills, can pollute fresh or salt water.

You can help protect your water supply:

  • Don't pour household products such as cleansers, beauty products, medicines, auto fluids, paint, and lawn care products down the drain. Take them to a hazardous waste collection site.
  • Throw away excess household grease (meat fats, lard, cooking oil, shortening, butter, margarine, etc.) diapers, condoms, and personal hygiene products in the garbage can.
  • Clean up after your pets. Pet waste contains nutrients and germs.

Zyrtec Product Quality Issue 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.
