Rumoquin NF is no longer being manufactured and information about its side effects is no longer available. Rumoquin NF was made using dexamethasone, diclofenac and methocarbamol, drugs that are known to cause numerous side effects including mood changes, headaches and digestive problems.
Rumoquin NF was a drug manufactured in Mexico by Marcel Laboratories. A typical bottle of medication contained 90 purple tablets. The medication contained phynelbutazone, a powerful painkiller that causes skin rashes, ear ringing, water retention and other less severe side effects. Rare side effects of phynelbutazone include cramping, anemia, fever, high blood pressure and kidney failure. Alarming side effects caused by dexamethasone include mental depression, breathing difficulties, heart palpitations and aggression. Rumoquin NF pills are stamped with the letter "M," which identifies its manufacturer.
The U.S. and Mexican governments discovered similarities between Rumoquin NF and a Mexican-made supplement called Reumofan that has mysterious origins. Clinical testing found that Reumofan pills contain quantities of dexamethasone, diclofenac and methocarbamol, and some of its purple pills are stamped with the Marcel Laboratories logo. Investigations have not found an official link between the discontinued medication and supplements sold as natural pain relievers. The U.S. Food and Drug Administration issued a health alert and recalled Reumofan supplements.
