Oxycodone is an opioid drug used in the treatment of moderate to severe pain. It comes under a variety of brand names, the most popular of which is OxyContin. This pain reliever is available by prescription only due to its addictive potential. Therefore, it’s essential to identify oxycodone pills, such as oxycodone 5mg, K18 pill or K 57 pill to ensure that one takes only the dose prescribed for them.

Brand Names

Oxycodone is a drug that is available under several different brand names, though also known as a generic drug for use in pain treatment.

However, other drugs contain oxycodone in addition to other medications, such as a combination of acetaminophen and oxycodone, sold under the brand names of Percocet or Endocet. Aspirin and this opioid are another popular combination, sold as Percodan, Endodan, and Roxiprin.

Note that these combination drugs should only be used if the doctor prescribes them. Moreover, some drug interactions may be severe, especially if one mixes oxycodone and alcohol. It can cause severe side effects, respiratory depression and even death.

Dosage Forms of Oxycodone

Oxycodone is available in several forms, which provide versatility for use for patients.

The Forms of This Medication Include the Following:

  • Extended-release tablets
  • Tablets (immediate-release)
  • Extended-release capsules
  • Capsules (immediate-release)
  • Solution
  • Concentrate

Note that the medication is also available in “abuse-deterrent” forms. It aims to reduce abuse rates with prescription opioid drugs, particularly injecting or snorting oxycodone. It does this by becoming a viscous substance when mixed with liquid, preventing it from passing through a needle, or making it physically difficult to crush tablets into powder.

It Is Available in the Following Strengths:

  • Immediate-release capsules: 5mg
  • Immediate-release tablets: 5mg, 7.5mg, 10mg, 15mg, 20mg, 30mg
  • Extended-release capsules: 9mg, 13.5mg, 18mg, 27mg, 36mg
  • Extended-release tablets: 10mg, 15mg, 20mg, 30mg, 40mg, 60mg, 80mg
  • Solution: 5mg/5mL
  • Concentrate: 20mg/mL

Identifying Pills

There are many reasons why being able to identify oxycodone pills is important. It will allow patients to know the dose they are about to take to prevent them from using more than they should. It can also provide information to those who deal with at-risk individuals in a clinical setting and work with patients to know which drug they might be using if they aren’t sure.

It’s vital to know that OxyContin is a prescription-only medication and is also a Schedule II drug, according to information from the Drug Enforcement Agency’s Controlled Substances Act. Such drugs can only be prescribed by a medical doctor, as they can determine the optimal dose and duration of treatment to minimize the risk of Oxycodone addiction developing.

What Does OxyContin Look Like?

Several companies produce oxycodone: either as a generic medication or under an array of brand names. As a result of this, the pills come in various shapes, sizes, and colors. Identifying these and knowing the dosages that they contain can help avoid OxyContin overdose or increased risk of negative health effects.
