Welcome to Healthcare Magic and thanks for your query.
I appreciate you for taking the initiative to quit smoking
and for seeking help regarding the same. Nicotine patches are part of the Nicotine Replacement Therapy
(NRT) programs, where low doses of nicotine is delivered to the body, in order to prevent withdrawal symptoms
and reduce craving.
In Trichy, you would be able to get them at Vasan Medicals. For your smoking pattern, you can start with a 14mg patch initially and then step it down to a 7mg patch.
Wish you all the best.
Dr. Jonas Sundarakumar
