Abstract: 
Tramadol is a synthetic opioid that is used to treat moderate to severe pain in both acute and chronic conditions. Tramadol is predominantly used off-label for premature ejaculation and euphoria among male youth in Nigeria, especially when dissolved in Lacasera® soft drink, which gives it a pleasant taste. Research has not yet examined the effects of this combination on hematological parameters, despite the fact that this type of abuse is common among young people and poses a public health risk. A 28-day subacute study was conducted with Wistar rats weighing 160-180g. The rats were separated into 8 groups of 6 each. The control groups: 1 and 2 were treated with Lacasera® and deionized water respectively. Groups 3, 4 and 5 received 35mg/kg per day, 70.7mg/kg per day and 106mg/kg per day of Tramadol dissolved in deionized water respectively. Groups 6, 7 and 8 received similar doses of Tramadol dissolved in Lacasera®. Blood samples were analyzed using auto-analyzer and standard methods. The data was analyzed using a statistical tool software (SPSS version 27). All results were presented as mean ± SD. Values were considered significant at p<0.05. Hematological analysis of groups treated with Lacasera®-Tramadol combination shows dose-dependent significant decreases (p<0.05) in PCVs, RBCs, and Hbs. WBCs and platelets increased in groups that received Lacasera®-Tramadol combination. The study concludes that regular or infrequent users of Lacasera® without Tramadol are unlikely to experience serious hematological complications. However, chronic Tramadol-Lacasera® users will experience increased toxicity over time, leading to hemolytic anemia.
