In patients' words

"Dr Manjappa has been very supportive and willingly takes time to review my medications and the interactions. Great confidence boost when she shares her findings with my GP and I know the team is all on the same page."

Birdeye patient review

"Please don’t go here if you want to get better. If you have a very minor case that is fine but if you actually have something severe do not. They don’t care about your situation and will make that very clear."
