Not Medical Advice: A red-speckled oval pill with a V on one side and 3604 on the other is acetaminophen/hydrocodone 325 mg / 5 mg (Norco, Lortab, Vicodin). The prescription medication belongs to the drug class narcotic analgesic combinations and is used to treat coughs, rheumatoid arthritis, back pain, and pain.
Less serious side effects of acetaminophen and hydrocodone include: dry mouth, constipation, mild nausea, headache, dizziness, drowsiness, blurred vision, and upset stomach.
Acetaminophen and hydrocodone 325 mg / 5 mg has a moderate potential for abuse and shouldn't be taken with alcohol or over-the-counter cough, cold, allergy, or pain medication. Alcohol combined with acetaminophen may increase your risk of liver damage.
Of interest, in light of the on going epidemic of hydrocodone abuse, an advisory panel to the FDA is suggesting that the drug be moved from its current classification as a Schedule III drug (a drug with moderate abuse potential) to the more restrictive Schedule II classification. Schedule II drugs are not eligible for refills.
