Tapentadol dependence through intravenous injection ('shooting') of crushed tablets associated with cutaneous pseudoallergic reactions.

Tapentadol is a synthetic opioid analgesic with a low risk of abuse and diversion. The rising trend of abuse of tapentadol is largely attributable to its intrinsic pharmacological profile and easy availability due to poor regulatory control. We report a case of intravenous injection of crushed tapentadol tablets that presented with cutaneous adverse drug reactions. Cutaneous adverse reactions are common in injection drug abuse, and clinical examination is a must to inspect the injection sites. Stringent regulatory measures are required to restrict the increasing abuse of tapentadol in India.

A Case of Delusional Disorder With Abuse of Isoniazid, Rifampicin, Pyrazinamide, and Ethambutol, the First-Line Anti-tuberculosis Therapy Drugs in India.

Tuberculosis (TB) and mental illnesses frequently coexist and are both extremely common worldwide. Through the National Program for Elimination of Tuberculosis (NTEP), anti-tuberculosis therapy (ATT) medications are used to treat tuberculosis in India. We want to report a case 45-year-old patient from the state of Andhra Pradesh, India with comorbid delusional disorder leading to daily ATT drug consumption for the past 20 years. This unusual presentation demonstrates that abuse of a Schedule "H" substance like ATT is also conceivable. To stop "Off-label" purchases, strict measures must be taken. Before beginning ATT, evaluating the patient's mental health may be a wise move.
