Tramadol is an opioid receptor that contains metabolite O-desmethyl tramadol M1. It also works as a serotonin releasing agent. But, the increase in serotonin level over the limit may cause nausea and vomiting. Hence, you should use it carefully.
It is available in various forms like oral tablets, capsules, liquid drops, etc. Capsules and tablets are widely used, and the liquid formula is primarily used in hospitals for injecting. For safety purposes, don’t consume it without a prescription, and don’t consider it for children below 12 years and elders above 75 years without a doctor’s advice.
In 2018, Tramadol was on the list of the most recommended pain-killers for the United States. It is also available as a street medicine with the names Chill pills, Tramal lite, etc. But, you should avoid purchasing any drug from street vendors and always prefer licensed pharmacy stores.
