Question: Hi, I am just recovering from pneumonia which was slow to react to antibiotics. I am home now and am taking Co-amoxiclav 500/125 3 times a day. I have had problems with slight diarrhoea which has settled but my poo is very dark, almost black, is this normal?

Brief Answer:
Side effect of amoxiclav

Detailed Answer:
Dear Ma'am, I have gone through your question and I understand your concerns but amoxiclav is reported to cause black tarry stools that could indicate the presence of occult blood in stools .. Amoxiclav can cause blood in stools due to hemorrhagic colitis which is inflammation of the mucus membrane of the colon.. I would recommend that you take a stool analysis and if it came positive for blood on stools then you should discontinue the antibiotic and refer to your doctor for a prescription of another antibiotic
