Hi, What you are describing as side effects of Paracetamol is unlikely and if at all, very rare. Some side effects related to paracetamol are mentioned below: Check with your doctor immediately if any of the following side effects occur while taking paracetamol: Rare Bloody or black, tarry stools bloody or cloudy urine fever with or without chills (not present before treatment and not caused by the condition being treated) pain in the lower back and/or side (severe and/or sharp) pinpoint red spots on the skin skin rash, hives, or itching sore throat (not present before treatment and not caused by the condition being treated) sores, ulcers, or white spots on the lips or in the mouth sudden decrease in the amount of urine unusual bleeding or bruising unusual tiredness or weakness yellow eyes or skin Get emergency help immediately if any of the following symptoms of overdose occur while taking acetaminophen: Symptoms of overdose Diarrhea increased sweating loss of appetite nausea or vomiting stomach cramps or pain swelling, pain, or tenderness in the upper abdomen or stomach area. Large doses of paracetamol causes Liver damage. Hence, I d still say that the symptoms you experience are that due to your cold and not paracetamol. To counter these symptoms, you may take cetrizine. Hope this information helps. Feel free to ask if you have any doubt. Regards, Dr. Sridhar
