High-dose IV vitamin C as alternative cancer treatment

Domain XII · Complementary, energy & biofield · Ewan Cameron, Linus Pauling · 1974 · Scotland

What it is

Who used it, where. A survey of practitioners attending complementary and alternative medicine conferences in 2006 and 2008 (published 2010) found 172 of 199 respondents had given IV vitamin C to patients, most often for infections, cancer and fatigue. It has been offered in private integrative,…

Format

• A typical alternative course, as patients experience it. Qualitative only; no amounts, concentrations or schedules are given.
• Sessions. Repeated intravenous drips over a course of treatment. Patients may experience increased urine output, thirst, nausea, vomiting and chills during or after an infusion. Fluid overload was reported in one study, possibly from the volume of fluid used to deliver the infusion.

Who practises it, and how they are trained or regulated

• Regulatory: the FDA has not approved high-dose vitamin C as a treatment for cancer. The RACGP's advice is that vitamin C infusions should not be given in general practice except within a properly conducted, ethics-approved clinical trial.

Evidence status, as the guide reports it

• General "vitamin drips": infusions promoted for sepsis, herpes zoster, COVID-19 and other conditions, for which the RACGP finds no supporting evidence; the TGA issued a safety alert that there is no evidence for IV high-dose vitamin C for COVID-19.

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Does it involve any substance, plant preparation, remedy or supplement? Has your doctor or prescriber been told, especially about any medication you take?
• Does it involve intense or unusual breathing? Have you been told about the medical conditions for which that is not advised?
• Does it involve fasting, a special diet or 'detox'? Have you discussed this with your doctor?
• Is it a group, retreat or community? How do they respond if someone wants to leave or raises a concern?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• prepaid packages, escalating costs when the cancer progresses, and relatives selling assets. Working: the person has a plan and support for the financial side.
• persuading, lecturing, or quietly withdrawing warmth when a client chooses differently from your view. Working: the client keeps talking openly about their choices.
• minimisation ("it's just detox"); in many alternative framings, worsening symptoms are described as the treatment working. Working: the client seeks medical review promptly.
• guarded answers, sudden topic changes, phrases from section 4, or a client who has stopped mentioning the oncology team. Working: the client volunteers details at later sessions.
• expectations of cure (higher risk) versus hopes of feeling better while continuing treatment (lower risk); intense fear of chemotherapy that may be treatable in its own right (needle or…

Problems the guide addresses

• Asking about complementary and alternative use, without judgement
• Exploring meaning, hopes and expectations
• Autonomy-respecting decision support
• Coordination with the treating doctor, oncology and palliative teams
• Recognising and responding to physical risk signals
• Assessment of clients who went through an alternative course
• Grief and regret
• Family conflict
• Financial harm
• Safeguarding and reporting

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
