Northern Prickly Ash and Nizatidine

Here is the interaction we found between these two, with the evidence behind it.

Minor

H2-BLOCKERS

Why this applies to Nizatidine

Nizatidine falls under H2-BLOCKERS — the group Northern Prickly Ash interacts with.

Theoretically, northern prickly ash might decrease the effectiveness of H2-blockers.
There are reports that northern prickly ash increases stomach acid.
Severity Minor 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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version. Nizatidine (Axid) works by turning down the amount of acid your stomach makes, which helps ulcers heal and calms heartburn. The concern with Northern Prickly Ash is that some old reports suggest it may actually nudge stomach acid up a bit. If that happens, it could work against what nizatidine is trying to do, so you might notice your heartburn or stomach discomfort isn't as well controlled.

Keep this in perspective though. This is rated a minor interaction, and the evidence behind it is anecdotal, meaning it's based on scattered reports rather than solid studies. It's not dangerous, just possibly less helpful for symptom relief. If you'd like to try the herb, mention it to your pharmacist or doctor first, and watch whether your symptoms creep back.

From our pharmacist’s overview on the Nizatidine page

“Nizatidine (Axid) reduces stomach acid to treat heartburn and ulcers, and its supplement list earns real attention rather than a passing glance. The one major-rated entry is activated charcoal, which can soak up the drug in the gut and cut how much reaches your bloodstream.”

About Northern Prickly Ash

What is Northern Prickly Ash?

Northern Prickly Ash
  • Toothache and mouth pain

Northern Prickly Ash is a North American shrub whose bark and berries have a long history in folk medicine, especially for toothache, joint pain, and sluggish digestion.

Talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

About Nizatidine

What Is Nizatidine Used For?

Brand names: Axid, Axid Injection

Nizatidine treats conditions caused by too much stomach acid. Both the capsule and oral solution are approved to treat active duodenal ulcers (ulcers in the small intestine) and active benign gastric ulcers (stomach ulcers), and to manage gastroesophageal reflux disease (GERD), including erosive and ulcerative esophagitis (inflammation and damage to the esophagus) and related heartburn.

After a duodenal ulcer heals, nizatidine can be continued at a lower dose to help prevent the ulcer from coming back. Nizatidine oral solution is also approved for adolescents 12 years of age and older for GERD and erosive esophagitis. Before treating a stomach ulcer, your doctor will rule out stomach cancer, since the symptoms can overlap.
