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.

What Does Oxycodone 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.

K18 Pill

K 18 Oxycodone pill.

The K18 pill is one of the most popular oxycodone 5mg pills available. It is white, round, and has a vertical groove separating K and 18 on one side. The K18 pill is manufactured by KVK Tech Inc. Stopping this pill will cause OxyContin withdrawal symptoms, and it’s better to manage them with the help of a healthcare professional.

K9 Pill

K 9 Oxycodone pill.

The K9 pill is much stronger than the K18 pill, as it contains 30mg of oxycodone. However, similar to the K18 pill, KVK Tech Inc also produces it. The K9 pill can be identified by its round shape and blue color. It has K and number 9 on one face.

K8 Pill

K 8 Oxycodone pill.

This tablet is round and green and is one of the oxycodone 15mg tablets that are available. It has K8 written on one of its surfaces. The drug, similar to the preceding entries, is also produced by KVK Tech Inc. The half-life of Oxycodone pills is 3-5 hours.

K56 Pill

K 56 Oxycodone pill.

The K56 pill is one that KVK Tech Inc produces. It is a round, pink tablet with a vertical groove that makes it easy to split. The K56 pill has an imprint of K 56 on the side with the groove. It contains 10mg of the opioid.

Mallinckrodt Pharmaceuticals is the producer of the M 5 tablet. It has an M situated in a box imprinted on one surface and a 5 above a horizontal line on the other. It’s a white, round oxycodone 5mg tablet. It’s important to note that regardless of dose, addiction can develop if used long enough.

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.

Taking Oxycodone with Caution

It’s essential to keep in mind that it is a Schedule II drug, and a medical doctor’s prescription is necessary to obtain it. Misuse of this medication can result in side effects and potentially addiction, overdose, and even death. It should be used only as described in the prescribing information provided by the medical doctor.
