Non sedating antihistamine syrup
You should also avoid alcohol if you are on a sedating antihistamine as they potentiate the effect of alcohol on the nervous system.Half a pint of beer will have the same effects as two or three pints and you might drive as if you were over the alcohol limit. Hence they are sometimes also referred to as sedating histamines. Their action on the brain means that they have a sedating effect.There may be a risk the medicines could affect each other, which could stop either from working properly or increase the risk of side effects.
When someone has an allergy to a normally harmless substance like pollen or pet dander, the immune system treats it as if it were 'foreign' like a virus or bacterium. There is some evidence that people who regularly take sedating antihistamines are more likely to have a serious accident.Antihistamines help stop this happening if you take them before you come into contact with the substance you're allergic to.Or they can reduce the severity of symptoms if taken afterwards.But in people with allergies, the body mistakes something harmless, such as pollen, for a threat.It then produces histamine, which causes symptoms such as rashes, a runny nose and/or sneezing.
