 Hi, I'm Dr. Olyth Selvan, Consulant Heptologist and Chairman Division of Liver Transplantation, Manipal Hospitals, Bangalore. With regards to painkillers, you are allowed to take painkillers in the prescribed dose for your age and body weight. Most of the painkillers are safe if they are taken with doctor's prescription in the limited dose within your age group and body weight. But when you start taking painkillers excessively, for example, even paracetamol taken excessively over a period of time, can result in liver failure. And painkillers taken when you already have a liver damage can lead to further worsening of the liver and also worsening of kidneys. With regards to ayurvedic medications, there are ayurvedic preparations for which we don't know the constituents which are inside these medical tablets or capsules which are given to you. And some of them might contain liver toxic medicines. And we do see a lot of patients who come to us after taking herbal ayurvedic medications with liver failure, even leading on to a situation where only a liver transplant can save them. So if you have to take any medications, especially over-the-counter herbal ayurvedic medications, you have to consult your doctor and get a clearance before you take these medications.
