Kratom & Hydrocodone (Oxycontin): Is It Safe To Mix?

Hydrocodone has been added as an adulterant to kratom (Mitragyna speciosa). When this happens, people can overdose or even die. It is not yet known exactly why this happens. 

Hydrocodone and kratom can be harmful to your liver. Therefore, it’s best to ask your doctor if you can take these two substances together.

Does Kratom Interact With Hydrocodone?

Kratom and hydrocodone are known to interact with each other. 

Both substances interact with the opioid receptors, and when taken together, they will potentiate each other’s effects [1]. This pharmacological phenomenon is known as an agonistic interaction.

Sedatives can also interact with hydrocodone, which means mixing it with certain kratom strains could be worse than others. For example, mixing hydrocodone with red vein kratom strains —the most sedative —should be avoided at all costs. 

These two substances are also metabolic competitors —meaning that they require the same liver enzymes to be metabolized in the body and thus will compete with each other when taken together.

Hydrocodone is metabolized in the liver by the CYPD26 and CYP3A4 enzymes [4]. Kratom is also metabolized by the same enzymes [5].

The metabolic competition between the two will lead to a dangerous accumulation of these substances in the body, increasing the risk of side effects and overdose.

Kratom & Opioids

Hydrocodone is classified as an opioid —it binds and activates the opioid receptors in the central nervous system [2]. There are dozens of other opioid medications, all of which will share a similar level of risk when used alongside kratom. 

Kratom should never be used with opioid medications unless specified by your prescribing doctor. 

Other related opioids kratom will interact with include: 

Is it Safe to Take Kratom With Hydrocodone?

No, it is not safe to mix these two substances. Be extra careful; there have been overdosing cases linked to kratom and hydrocodone.  

Be sure to let your doctor know if you’re planning on taking both substances. They can give you the best professional advice considering your particular case. Additionally, they’ll be able to help you monitor yourself for potential interactions. 

What is Hydrocodone?

Hydrocodone is a semi-synthetic opioid medication used to treat pain. It is also an antitussive indicated for cough in adults. This controlled medication can only be obtained with a doctor’s prescription and is available in tablets, capsules, and oral solutions [3]. 

Hydrocodone should only be taken when no other pain relievers work. It can be habit-forming and should never be taken differently than prescribed.

What is Kratom?

Kratom is a plant that originated in Southeast Asia. It has been used in the west since the 19th century, but people in countries like Indonesia, Vietnam, and Thailand have used it for hundreds of years as traditional medicine. It offers pain relief in high doses and works as a sedative in lower doses. 

What’s Kratom Used For?

People in Southeast Asia regularly chew on raw kratom leaves. However, you can also take kratom as a powder, brew kratom leaves into a tea, or smoke them

Kratom can benefit various health concerns, ranging from insomnia and anxiety to elevating mood and enhancing physical endurance

What’s The Dose of Kratom?

Your ideal kratom dosage might vary depending on what you need it for and how much experience you have. 

However, the general kratom dosage guidelines are as follows: 

  • Low-Dose Kratom (2 to 6 grams) 
  • High-Dose Kratom (6 to 12 grams)

Be sure not to take more than 12 grams at a time since you could experience kratom’s side effects.

What are the Side Effects of Kratom?

As with most other supplements and medications, kratom has a list of possible undesired effects. The chances of experiencing these side effects, however, can be minimized if you take kratom following the dosage guidelines and take regular tolerance breaks.

The most common side effects of kratom include:

What are the Different Types of Kratom?

  1. White Vein Kratom The most stimulating strain, boosts motivation and mood. 
  2. Red Vein Kratom Sedating and relaxing helps with sleep and pain relief.

  4. Yellow Vein Kratom — Weaker than the white vein, enhances mood, and improves concentration. 

Key Takeaways: Is it Safe to Mix Kratom & Hydrocodone?

Because of the interactions between hydrocodone and kratom, this combination is not safe and should be avoided. This is especially dangerous when hydrocodone is mixed with kratom as an adulterant. 

They are both known to cause liver issues and may increase each other’s effects — leading to a higher chance of side effects. 

Always speak to your doctor before you begin taking hydrocodone and kratom together. They can help you determine if the rewards outweigh the risks.
