Oxygen Therapy and Chloramphenicol

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 Chloramphenicol and Oxygen Therapy in our sources. This does not guarantee that the combination is completely free of risk — research on Oxygen Therapy alongside specific medications may be limited.

Worth understanding: our licensed dataset holds no drug-interaction record for Oxygen Therapy at all — not against Chloramphenicol, 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.

Oxygen Therapy is a treatment rather than something you take. Tell whoever provides it which medicines you use, and ask your prescriber whether it is 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.

Oxygen Therapy safety at a glance

Oxygen Therapy overall Use caution Medical oxygen is safe and lifesaving when prescribed, but it is a drug that can cause harm if used without proper testing and monitoring.
Pregnancy Use caution Supplemental oxygen may be used in pregnancy when medically needed, but only under a doctor's supervision.
Breastfeeding Use caution Use only as directed by a healthcare provider; medical oxygen does not pass into milk, but the underlying condition needs proper care.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What to actually watch for

What Chloramphenicol’s Own FDA Label Lists

This is not an interaction — none of it involves Oxygen Therapy. These are the most notable effects listed in the ADVERSE REACTIONS section of Chloramphenicol’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 have Oxygen Therapy and take the medicine. 8 of them are worth acting on rather than waiting out — marked below.

  • Confusion Worth acting on
  • Low mood Worth acting on
  • A low platelet count Worth acting on
  • Anemia Worth acting on
  • A severe allergic reaction Worth acting on
  • Hives Worth acting on
  • A low white blood cell count Worth acting on
  • An allergic reaction Worth acting on
  • Mouth irritation or sores
  • Bloating or gas

Showing the 10 most notable of 15 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 Chloramphenicol. Read the label on DailyMed › Where a percentage is shown, it is the share of 28 voluntary FDA FAERS reports for Chloramphenicol that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Oxygen Therapy’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Oxygen Therapy side to compare — that is a limit of the record, not a statement that Oxygen Therapy has no side effects.

Everything else you take

See Every Supplement That Interacts With Chloramphenicol

This page covers Oxygen Therapy only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Chloramphenicol page lists 32 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Bacillus Coagulans (moderate), Bacillus Subtilis (moderate), Bifidobacterium Animalis Subsp. Lactis (moderate), Bifidobacterium Bifidum (moderate) and Bifidobacterium Breve (moderate).

By severity: 30 moderate · 2 minor.

From our pharmacist’s overview on the Chloramphenicol page

“Almost everything on this chloramphenicol list points at the supplement rather than the drug. Chloramphenicol is a powerful antibiotic, usually reserved for serious infections or used as eye drops, and the great majority of entries are probiotics and fermented products such as acidophilus and Bifidobacterium strains.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Oxygen Therapy is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Oxygen Therapy reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Oxygen Therapy and Chloramphenicol records this page draws on were last updated June 20, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Oxygen Therapy

What is Oxygen Therapy?

  • Low blood oxygen from lung disease (COPD)
  • Severe COVID-19 or pneumonia
  • Hyperbaric treatment of wounds and decompression sickness
  • Carbon monoxide poisoning
  • Cluster headaches
  • Marketed for 'energy,' altitude, or general wellness

Oxygen therapy is a real medical treatment that gives extra oxygen to people whose blood oxygen is low, and it can be lifesaving when prescribed and monitored by a healthcare provider. It is not a dietary supplement, and using too much oxygen or relying on unproven 'oxygen' wellness products can be harmful or simply ineffective. Always use oxygen only under medical guidance.

Medical oxygen gas (nasal cannula, face mask, oxygen concentrator), hyperbaric oxygen chambers, and marketed 'oxygen' products such as canned oxygen, oxygenated water, and hydrogen peroxide drops

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

Oxygen Therapy: dosing

There is no single 'dose' of oxygen that fits everyone. Medical oxygen is prescribed and adjusted by a healthcare provider based on your blood oxygen levels, your condition, and your symptoms. It is usually measured as a flow rate (liters per minute) or a percentage of oxygen, and often guided by a fingertip oxygen monitor (pulse oximeter) or blood tests.Because the right amount is so individual, you should never change your oxygen flow or stop it on your own.

About Chloramphenicol Injection

What Is Chloramphenicol Injection Used For?

Brand names: Chloromycetin, Chloromycetin Ophthalmic, Chloromycetin Injection

Chloramphenicol Sodium Succinate Injection is used intravenously to treat serious infections caused by susceptible bacteria. It is active against organisms including Haemophilus influenzae, Salmonella species (including Salmonella typhi, the cause of typhoid fever), Rickettsia, and the lymphogranuloma-psittacosis group.

Because of its serious risks, this medication is reserved for infections where less dangerous antibiotics will not work. It must not be used for minor infections such as colds, flu, or sore throats, or to prevent infections.

Most-Reported Side Effects for Chloramphenicol

From FAERS, the FDA’s public side-effect reporting system (28 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
