As the best kratom experts blog online, our goal is to help you get the most results from kratom. For centuries, this natural botanical has been used by millions of people to improve focus, uplift moods, increase energy levels, and reduce anxiety.
We often get questions about which medications to avoid when using kratom. It’s not just about being cautious; it’s about using kratom wisely and safely. Even though kratom is plant-based, it has powerful alkaloids that interact with the body’s nervous system.
When kratom is used alongside certain medications, the effects can change and sometimes cause side effects like nausea, dizziness, and high blood pressure.
5 Major Drug Classes To Avoid or Use With Caution When Using Kratom
Kratom supplements are not compatible with some prescription and over-the-counter medications.
Pain Relievers and Opioids
For starters, kratom targets opioid receptors in the brain, just like pain medications. Combining kratom with prescription opioids, like oxycodone, methadone, and morphine, can result in respiratory depression and sedation. The FDA strongly advises against using kratom with opioids and pain relievers.
Sedatives and Benzodiazepines
This includes medications such as alprazolam, diazepam, and other CNS depressants. They can cause serious side effects when used alongside kratom because they both can potentially cause sedation.
Their interactions result in breathing problems, which eventually result in loss of consciousness. In this report, WebMD warns against using kratom alongside sedative medications.
Serotonergic and Antidepressants
Examples of drugs in this class are tricyclics, SNRIs (serotonin-norepinephrine reuptake inhibitors), and SSRIs (selective serotonin reuptake inhibitors). These drugs affect the production of the serotonin hormone.
Kratom has the potential to inhibit liver enzymes that metabolize antidepressants. It also affect production of serotonin hormone. We stumbled on a case study that highlighted a patient who developed QTC prolongation and serotonin syndrome after taking large doses of kratom while on quetiapine and venlafaxine medications.
The dangers of using kratom and serotonergic drugs together are also documented in this WebMD report. The two can interact and cause severe heart problems and seizures.
Medications Processed by CYP Enzymes
Kratom is metabolized or broken down by CYP enzymes. The active alkaloids in kratom can inhibit these enzymes. So, any medications that rely on these pathways may behave differently.
According to WebMD, kratom can potentially reduce the rate at which the body breaks down certain medications, thus increasing their effects and side effects. Chemotherapy agents, heart drugs, and antipsychotics are a few of the medications that are metabolized by CYP enzymes.
Blood Pressure and Heart Medications
The FDA recently published an article that highlighted the dangers of combining kratom with blood pressure and heart medications like beta blockers and ACE inhibitors. Using the two can result in respiratory and cardiovascular complications.
Common Side Effects Of Using Kratom With These Medications
Kratom can magnify or change drug effects. Here are some of the common side effects of using kratom with medications.
- Sedation and breathing complictions
- Unexpected cardiac issues like arrhythmia and QTc prolongation
- Liver stress and toxicity
- Serotonin syndrome effects like tremors, agitation, rapid heart rate, and fever
- Slows down the metabolizing of drugs
You can cushion yourself from these side effects by not only avoiding the drug classes listed above, but also purchasing from a reputable kratom brand like Real Botanicals.
How to Use Kratom Safely If You’re on Medications
Virtually all medications have side effects, so if you are convinced to use kratom, let these side effects not discourage you. Here are expert tips on how to use kratom safely if you are also on medications.
- Always inform your doctor about your kratom use
- Avoid combining kratom with any medication in the classes above unless your doctor explicitly approves.
- Start with small doses of kratom and increase it gradually based on how your body responds.
- If you are on medication that is sensitive to timing, consider spacing kratom by at least 4 – 6 hours from your medicine, but only under the guidance of your doctor.
- Watch for breathing difficulty, high heart rate, tremor, confusion, or any unusual reaction. Stop using or reduce the dose if you experience any of these symptoms.
- Because different kratom products have varying alkaloid levels and may be contaminated, choosing a reputable kratom brand is key.
- Avoid using kratom daily when on medications. Periodic and careful use reduces tolerance and potential dependency.
- Don’t combine kratom with caffeine, alcohol, or benzodiazepines without your doctor’s advice.
