heart attack
"My father experienced TIA symptoms, taste disturbance, severe weight loss, nausea, pins and needles, speech difficulties and a few hallucinations or visual disturbances over the first eight days of taking clopidogrel with repeated admissions to hospital. He was treated as if he had a TIA although no evidence for it and removed from clopidogrel for ten days during which all symptoms ceased and he returned to normal. He then resumed clopidogrel and the symptoms returned but after a couple of weeks he went into an increasing decline with pain radiating from his lower back, depression, increasing frequency of visual disturbance constipation lethargy, confusion. He was taken off clopidogrel after five weeks and all pain, loss of appetite etc left"
