I was ill with rheumatic fever when I was nine years old. And the doctor advised 5 years of Pendura injections at 21/21 day intervals. I took about 1.5 years. And another doctor advised me to use Penisol Vk 250 mg once a day until I reach 50 kg and twice a day after 50 kg until I am 21 years old. Now I have 6 months left for my 21st birthday. And I am fit and fine now, what is the process to get me off this medicine? What are the effects after leaving?or there is no effect, I would like to sincerely request the concerned doctor to inform me in detail about this.
