Antihistamines are drugs that block the effect of the body's own messenger substance histamine, which plays a central role in allergic reactions.
Add as Preferred SourceAntihistamines are drugs that block the effect of the body's own messenger substance histamine, which plays a central role in allergic reactions.
Antihistamines are primarily used to treat allergies such as hay fever, hives or allergic asthma. Antihistamines are also used for nausea, sleep disorders and as a component of certain painkillers. A distinction is made between H1 antihistamines (against allergic reactions) and H2 antihistamines (to reduce stomach acid production).
An important but often overlooked aspect is the interaction of antihistamines with certain vitamins and minerals. In particular, vitamin C plays a key role, as it can naturally reduce histamine levels in the body. Studies show that a lack of vitamin C correlates with increased histamine levels, which can intensify allergic reactions. An adequate supply of vitamin C could therefore support the effect of antihistamines or even have a preventative effect.
