Relaxation Therapy and Ranitidine

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Ranitidine and Relaxation Therapy in our sources. This does not guarantee that the combination is completely free of risk — research on Relaxation Therapy alongside specific medications may be limited.

Worth understanding: our licensed dataset holds no drug-interaction record for Relaxation Therapy at all — not against Ranitidine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

Relaxation Therapy is a practice rather than something you take. Ask your care team whether the type and intensity you plan to practice are appropriate for your health and treatment. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What Ranitidine’s Own FDA Label Lists

This is not an interaction — none of it involves Relaxation Therapy. These are the most notable effects listed in the ADVERSE REACTIONS section of Ranitidine’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you practice Relaxation Therapy and take the medicine. 10 of them are worth acting on rather than waiting out — marked below.

  • A slow heartbeat Worth acting on
  • Hallucinations Worth acting on
  • Pancreatitis Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • An irregular heartbeat Worth acting on
  • Wheezing Worth acting on
  • Confusion Worth acting on
  • A severe skin reaction Worth acting on
  • Low mood Worth acting on
  • A low platelet count Worth acting on

Showing the 10 most notable of 37 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Ranitidine. Read the label on DailyMed › Where a percentage is shown, it is the share of 230,801 voluntary FDA FAERS reports for Ranitidine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Relaxation Therapy’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Relaxation Therapy side to compare — that is a limit of the record, not a statement that Relaxation Therapy has no side effects.

From our pharmacist’s overview on the Ranitidine page

“Ranitidine (Zantac) is a heartburn and ulcer medicine gentle enough to have sold over the counter, but two of the 74 supplements and herbs on file with it earn real caution and are worth understanding first. Activated charcoal can soak up ranitidine in the gut and blunt the dose, and St.”

About Relaxation Therapy

What is Relaxation Therapy?

  • Anxiety and stress
  • Trouble sleeping
  • Chronic pain
  • High blood pressure
  • Headaches
  • Calming before medical procedures

Relaxation therapy is a group of mind-body techniques—like deep breathing, guided imagery, and progressive muscle relaxation—used to reduce stress and promote calm. It is low-risk for most people and has moderate evidence for easing anxiety, stress, and some pain or sleep problems. It is best used alongside, not instead of, standard medical care.

Not applicable (mind-body practice) · Guided imagery, progressive muscle relaxation, deep breathing, autogenic training, biofeedback, meditation

An interaction check asks whether these two react with each other — it does not ask whether Relaxation Therapy is a good idea for someone in your situation. Here is what our Relaxation Therapy record says about it on its own.

Relaxation Therapy: dosing

There is no standardized "dose" for relaxation therapy. Many programs suggest practicing for about 10 to 20 minutes once or twice a day, but what matters most is regular, consistent practice.You can use guided apps, audio recordings, classes, or work one-on-one with a therapist or biofeedback specialist.

About Ranitidine

What Is Ranitidine Used For?

Brand names: Zantac 150 EFFER, Zantac 150 GEL, Zantac 150, Zantac Geldose, Zantac, Ranit, Zantac Efferdose, Zantac 300, Zantac 300 GEL, Ranitidine injection

Ranitidine treats a range of stomach acid–related conditions. Prescription-strength ranitidine (capsules, tablets, and oral solution) is used for active duodenal ulcers (ulcers in the small intestine), active benign gastric ulcers (stomach ulcers), GERD (acid reflux disease), erosive esophagitis (acid damage to the esophagus), and pathological hypersecretory conditions — rare disorders where the stomach makes far too much acid, such as Zollinger-Ellison syndrome. It is also used as maintenance therapy to keep duodenal and gastric ulcers from coming back after they have healed.

Over-the-counter products — including Acid Reducer and Acid Reducer 150 tablets — are approved to relieve heartburn associated with acid indigestion and sour stomach, and to prevent that heartburn when taken before eating or drinking foods that trigger it.

Most-Reported Side Effects for Ranitidine

From FAERS, the FDA’s public side-effect reporting system (230,801 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Breast cancer 29,413 reports
Prostate cancer 26,446 reports
