Hi I’ve had 6 sessions of bcg treatment, last one in December. Now a month later I’m waking up in the night by feelings of nausea and vomiting. Is this normal?
BCG stimulates the immune system, sometimes excessively to attack organs with fast turnover of cells such as bladder, intestines, liver and rarely the hair [hair falling out is a rare side effect]. I had to suffer the side effects with my third BCG but it was fortunately less than 24 hours.
