Although some studies have found that blood 
alcohol levels can be slightly rais 
 possibly remain elevated for longer than usual in those taking H2-receptor antag 
 other studies report that no significant interaction occurs. Hypoglycaemia, whi 
 occur following 
alcohol intake, may be enhanced by 
H2-receptor antagonists. 
 Extensive reviews of the data have concluded that the interaction is not, in general, clinically significant. There are insufficient grounds to justify any general warning regarding 
alcohol and 
H2-receptor antagonists, but note that many of the conditions for which 
H2-receptor antagonists are used may be made worse by 
alcohol, so restriction of drinking may be needed.
