Hello, You have been takin the pain killer Tapal, Tapentadol (50mg). Tapal-ER 50 Tablet may be prescribed alone or in combination with another medicine. You have been unable to give up the medication you have been taking for almost 3 yrs. You have developed dependence or addiction for the medicine. It may take a little longer time to come out of it. Be patient and focused to successfully come out of it. You are advised to get connected to a local GP or health care provider or a detox center before you start to stop taking painkiller. If not, you may go into painkiller withdrawal. You should wean off of your pain medication gradually and safely. Reduce the dose every 3-4 days. Even with a slow weaning process, you may experience some withdrawal symptoms. Depending on the dose of the drug you ve been taking and how long you ve been taking the drug, it may take weeks or even months to gradually and safely reduce your dose and get off your medication. Get connected to a detox center so that your withdrawal symptoms can be timely and comfortably managed.
