Mesulid is an anti-inflammatory drug which is part of the sulfonanilide group - this is the same effects of ibruprofen and can increase bleeding.It is also toxic to liver and kidnesy in high dosages.
Lonarid is the same drug as paracetamol (Acetaminophen)
In a nut shell paracetamol may take a slight edge off but you would be risking your liver if you took enough to numb the pain from a tattoo.
I have nearly comepleted an ebook which covers this below is an extract about paracetamol;
Paracetamol (AKA Panadol, Effralgan, Doliprane, Lonarid)
Similar to aspirin in the effectiveness of pain relief paracetamol is one of the most popular prescription free painkillers available worldwide. The original drug was called Acetanilide but got off to a rocky start as early studies in the mid 1880’s suggested that this substance was responsible for severe toxic effects that resulted in the body being unable to carry oxygen effectively around the body. This is known as cyanosis.
Following further research during the 1940’s it was decided that the earlier findings were unfounded and by the mid 1950’s paracetamol was marketed. It is now produced and consumed globally. This now is known as Acetaminophen.
Paracetamol is very effective at pain relief for moderate pain and is fast acting especially in liquid form, and can become active within 20-30 minutes and last for around 4 hours per dose. The effectiveness will vary from person to person. This is because each person is able to process the chemicals at differing rates. However it does not have the same gastric damage that can be sometimes caused by aspirin.
The main drawback of paracetamol is that because it is activated in the liver it can result in organ failure quickly if consumed in too high a dosage. Liver failure is the most common result of a paracetamol overdose. This is because large amounts would be required to numb the pain totally of a tattoo.
Again there is no cure for an overdose other than a liver transplant.
Just have a good meal before hand plenty of water and a caffinated drink and you will fly through the tattoo drug free.
The only difference between a person with tattoos, and a person without is this. The person with tattoos does not care if you do not have any.
