There can be three possibilities for your symptoms.As told earlier, it is usually not the alcohol that produces the allergic reaction to the wine or beer. The other ingredients in the alcohol, such as yeast, sulfur dioxide, and additives are often the culprits.They can cause hives,itching and swelling.
Secondly,alcohol consumption can cause changes in the liver. Advanced liver damage makes it difficult for your body to break down waste products (such as bilirubin) in your blood. Waste products in the bloodstream can also cause itching, nausea, fever, and body aches
Thirdly,alcohol intake in excess can cause alcoholic myopathy. The severe form of acute alcoholic myopathy is associated with the sudden onset of muscle pain, swelling, and weakness; a reddish tinge in the urine caused by myoglobin, a breakdown product of muscle excreted in the urine; and a rapid rise in muscle enzymes in the blood.
Avoidance of alcohol is the main treatment available.Other treatment options include antihistaminics,corticosteroids and immunotherapy.Pls don’t double the dose of zyrtec as it may lead to drug overdose. The recommended dose of zyrtec is 5 mg or 10 mg per day in adults and not more than that.
