The risk of faecal blood loss, 
gastrointestinal haemorrhage and other bleeding is increased by concurrent use of clopidogrel and 
NSAIDs. 
Ticlopidine is expected to interact similarly. 
 The manufacturers advise caution if 
NSAIDs and 
ticlopidine are given together. Consider giving additional 
gastrointestinal prophylaxis such as a proton pump inhibitor in patients at risk of 
gastrointestinal ulceration and bleeding.
