Interaction report

Ashwagandha and Celecoxib, Tramadol

These two interact in 3 distinct ways. Each one is explained separately below.

Why Are There 3 Interactions?

Ashwagandha interacts with whole categories of medication. Celecoxib, Tramadol falls into 3 of those categories, so it can interact with Ashwagandha in 3 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CNS DEPRESSANTS

1 of 3

Why this applies to Celecoxib, Tramadol

Celecoxib, Tramadol falls under CNS DEPRESSANTS — the group Ashwagandha interacts with.

Theoretically, taking ashwagandha might increase the sedative effects of CNS depressants.
Ashwagandha seems to have sedative effects. Theoretically, this may potentiate the effects of barbiturates, other sedatives, and anxiolytics.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Seglentis combines two medicines: celecoxib (an anti-inflammatory) and tramadol (an opioid pain reliever). The piece that matters here is the tramadol, since it can already make you feel drowsy, foggy, or relaxed. Ashwagandha is thought to have mild calming, sleep-promoting effects of its own, so the worry is that pairing the two could stack that sleepiness on top of each other.

To be fair, this is a theoretical concern based on how ashwagandha seems to work, not on strong human studies, so it may never cause you trouble. Still, if you notice extra grogginess, dizziness, or trouble concentrating, that is a sign to ease up. Please check with your pharmacist or doctor before combining them, and don't drive until you know how you feel.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 3

Celecoxib, Tramadol also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

Theoretically, ashwagandha might decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that ashwagandha extract induces CYP3A4 enzymes.
Severity Minor Likelihood Possible Evidence D

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Seglentis combines two medicines: celecoxib (an anti-inflammatory for pain) and tramadol (an opioid-type pain reliever). The lab-only finding here suggests ashwagandha may slightly speed up a liver enzyme called CYP3A4, which helps process both of these drugs. In theory, that could lower their levels a bit and make the pain relief feel weaker.

Here's the important part: this is based only on test-tube research, it's rated as a minor interaction, and it may never show up in real life. Tramadol is a bit of a special case because part of it is activated into its pain-relieving form, so the effect isn't simple. I wouldn't lose sleep over this, but if you notice your pain isn't as well controlled, check in with your pharmacist or doctor before changing anything.

Serotonergic Drugs

3 of 3

Celecoxib, Tramadol also falls under Serotonergic Drugs.

Some animal studies have reported that ashwagandha can enhance serotonergic transmission by altering certain serotonin (5-HT) receptors. However, there is no evidence to suggest that ashwagandha increases the risk of serotonin-related effects, and there have been no published case reports of serotonin syndrome when combined with other serotonergic drugs. Nevertheless, due to the lack of extensive studies on the matter and the fact that ashwagandha appears to affect serotonergic pathways, it would be prudent to exercise caution when combining it with drugs that affect serotonin.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

The combo pill you're asking about (Seglentis) pairs celecoxib, an anti-inflammatory, with tramadol, a pain reliever. The piece that matters here is the tramadol part, because tramadol nudges up serotonin in the brain. Ashwagandha may gently touch serotonin pathways too, so in theory stacking them could add to that effect.

I want to be honest with you though: this is a very weak, mostly theoretical concern. It comes from animal studies, and there are no real-world reports of problems when ashwagandha is taken with serotonin-affecting drugs. The chance of true serotonin syndrome (agitation, fast heartbeat, sweating, shivering, tremor) is low. Still, since tramadol already carries that risk on its own, it's worth a quick chat with your pharmacist or doctor before starting ashwagandha.
