When conventional painkillers are ineffective, a prescription drug called Norco 10-325 mg is used to treat moderate to severe pain. It contains 325 mg of acetaminophen and 10 mg of hydrocodone bitartrate. While acetaminophen is a non-opioid analgesic that helps lower pain and fever and intensifies the overall pain-relieving impact, hydrocodone is an opioid pain reliever that acts by altering pain signals in the brain and nervous system. When you buy Norco 10-325 mg online, it appears frequently; however, healthcare authorities emphasize that Norco must only be dispensed through licensed pharmacies with a valid prescription. The hydrocodone dose is higher than in lower-strength versions. Norco 10-325 mg is typically prescribed for more intense pain, such as after surgery or serious injury. Common side effects may include drowsiness, dizziness, nausea, constipation, and headache. Serious risks include slowed breathing, dependence, misuse, and addiction.
