Relaxation Therapy and Opicapone

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 Opicapone 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 Opicapone, 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 to actually watch for

What Opicapone’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 Opicapone’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. 4 of them are worth acting on rather than waiting out — marked below.

  • Hallucinations Worth acting on mentioned in 13.9% of FDA reports for Opicapone
  • Fainting Worth acting on
  • Confusion Worth acting on
  • Raised blood pressure Worth acting on
  • Weight gain
  • Weight loss
  • Dry mouth
  • Low blood pressure
  • Drowsiness
  • Trouble sleeping

Showing the 10 most notable of 12 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 Opicapone. Read the label on DailyMed › Where a percentage is shown, it is the share of 2,261 voluntary FDA FAERS reports for Opicapone 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.

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 Opicapone

What Is Opicapone Used For?

Brand name: Ongentys

Ongentys (opicapone) is used alongside levodopa/carbidopa to treat Parkinson's disease in adults who experience 'off' episodes — periods when medication wears off and Parkinson's symptoms return before the next dose is due.

It is not used alone. Ongentys works as an add-on to help levodopa stay active longer, reducing the time patients spend in these 'off' states.

Most-Reported Side Effects for Opicapone

From FAERS, the FDA’s public side-effect reporting system (2,261 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Hallucination 314 reports
Dyskinesia 306 reports
Fall 258 reports
On and off phenomenon 158 reports
Tremor 143 reports
