If you're getting Myers Cocktails, NAD+, high-dose Vitamin C, or iron infusions, your primary care doctor needs to know — not because IV therapy is risky, but because your labs, medications, and chronic conditions all factor into a safe plan. This guide gives you the exact script and paperwork to make that conversation five minutes instead of thirty.
TL;DR
- Bring the exact formula name and dose — 'Myers Cocktail' or 'high-dose Vitamin C 25g' means something specific to a physician, 'IV vitamins' does not.
- Disclose current medications first — anticoagulants, diuretics, and chemo drugs can interact with iron or high-dose Vitamin C infusions.
- Ask your PCP to check G6PD status before continuing high-dose Vitamin C above 15 grams — this is standard screening in 2026, not optional.
- A board-certified, physician-led provider like Infusion Center of NJ can send your PCP a treatment summary directly, which shortens this whole conversation.
- Verdict: bring your infusion record and recent labs, name the exact formula, and ask about interactions — skip the conversation and you skip a safety check your PCP is trained to run.
Why this matters
IV therapy sits outside most primary care training, so your PCP is working with less information than you think unless you supply it. Iron infusions can mask anemia patterns your doctor is tracking with routine bloodwork. High-dose Vitamin C interacts with kidney function and, in rare cases, with glucose-6-phosphate dehydrogenase (G6PD) deficiency — a screening question that matters more in 2026 than it did five years ago, as more infusion centers have added it to standard intake.
NAD+ and Myers Cocktail formulas are generally low-risk, but if you're on anticoagulants, diuretics, or chemotherapy, your PCP needs the full picture to avoid a conflict nobody flagged. A five-minute disclosure prevents a much longer conversation later if something goes wrong.
What you'll need
- The exact name and dose of your infusion ("Myers Cocktail," "NAD+ 500mg," "high-dose Vitamin C 25g," "iron infusion — ferric carboxymaltose")
- A copy of your infusion record or receipt showing the date and ingredients
- Your current medication list, including supplements and over-the-counter drugs
- Recent bloodwork if you have it — kidney panel, iron studies, CBC
- 10 to 15 minutes at your next appointment, or a phone message if it's urgent
- The contact information for your infusion provider, in case your PCP wants to confirm details directly
A physician-led practice like Infusion Center of NJ can typically provide a written summary of your treatment plan on request, which removes most of the guesswork from this step.
The steps
1. Write down exactly what you're getting
Vague descriptions slow this conversation down. "IV vitamins" tells your PCP nothing; "Myers Cocktail with 1000mg Vitamin C, B-complex, and magnesium, every three weeks" tells them everything they need to assess risk. Write the formula name, dose, and frequency on a single line before your appointment. Common mistake: describing the treatment by brand or trend name only — ask your infusion provider for the clinical ingredient list if you don't already have it.
2. Bring your infusion record
Most reputable infusion centers issue a receipt or after-visit summary listing what was administered and when. Hand this to your PCP instead of trying to recall details from memory. Common mistake: relying on a verbal recap weeks after the infusion — details about dose and additives get fuzzy fast.
3. Explain why you started
Your PCP will ask about the clinical reason: fatigue, migraine recovery, dehydration, immune support, or a broader wellness plan. State it in one sentence — "I started NAD+ infusions in 2026 for energy and recovery after a period of high stress" is enough. Common mistake: over-explaining the marketing pitch instead of the medical rationale; stick to symptoms and goals.
4. Disclose your labs
If you've had iron studies, a kidney panel, or a CBC in the last six months, bring the results or ask your PCP to pull them. Iron infusions and high-dose Vitamin C both interact with kidney and blood chemistry, so this is the step that actually changes clinical decisions. Common mistake: assuming your infusion provider already shared labs with your PCP — confirm this instead of assuming it.
5. Ask about medication interactions
Name every prescription and supplement you're on, especially anticoagulants (warfarin, apixaban), diuretics, and chemotherapy drugs. Iron infusions can interact with oral iron supplements you're already taking, and high-dose Vitamin C can affect certain lab-based diabetes monitoring. Common mistake: forgetting supplements — fish oil, multivitamins, and herbal blends count too.
6. Request a G6PD screening if relevant
If you're receiving or considering high-dose Vitamin C above 15 to 25 grams, ask your PCP whether a G6PD deficiency test makes sense first. This single blood test rules out a rare but serious complication and takes one office visit to arrange. Common mistake: skipping this because symptoms haven't appeared — G6PD deficiency is often silent until a high dose triggers it.
7. Ask your PCP to document the conversation
Having your infusion plan noted in your chart means any future provider — an ER doctor, a specialist, a new PCP — sees the full picture instantly. This takes your PCP under two minutes and protects you if you ever need urgent care. Common mistake: assuming this happens automatically; ask directly for it to be added to your record.
8. Schedule a follow-up if you're starting something new
If you're beginning NAD+ or iron infusions for the first time in 2026, ask for a follow-up lab check in 4 to 6 weeks to confirm your body is responding as expected. Common mistake: treating the first conversation as the only one — infusion plans should get periodic review, not a one-time disclosure.

Troubleshooting
Your PCP says IV therapy isn't "medically necessary." That's a fair clinical distinction — most Myers Cocktail and NAD+ infusions are elective wellness treatments, not covered procedures. Ask instead whether it's safe given your current health status; that's the question your PCP is actually equipped to answer.
Your PCP raises concern about kidney load from Vitamin C. This is a reasonable flag, especially above 15 grams per session. Ask for a kidney function panel before your next infusion and share the result with your infusion provider.
Your PCP hasn't heard of NAD+ infusions. NAD+ therapy is newer to mainstream primary care than Myers Cocktail or iron infusions. Bring your provider's clinical summary and offer to have your infusion physician call if questions come up — a physician-to-physician conversation resolves this faster than you relaying secondhand information.
You're on an iron supplement and getting iron infusions. Tell your PCP immediately — doubling iron intake without monitoring can push ferritin too high. Your PCP will likely pause the oral supplement while infusions continue.
Your PCP wants records from the infusion center directly. This is normal and often faster than you relaying details yourself. Ask your infusion provider for a fax or portal transfer option.
You're not sure which labs to bring. At minimum, bring a CBC and iron panel if you've had one in the past year; a kidney panel matters most for high-dose Vitamin C users.
Tools and resources
- Your infusion receipt or after-visit summary, with formula name and dose
- A written medication and supplement list, updated before the appointment
- Recent labs — CBC, iron panel, kidney panel — if available
- Infusion Center of NJ, for a physician-led treatment summary your PCP can review directly
- A follow-up appointment booked in advance if you're starting a new infusion type in 2026
What to do next
Once your PCP has the full picture, ask for a copy of the chart note so you have your own record of the conversation. If you're due for a new type of infusion — NAD+, iron, or a higher Vitamin C dose than before — loop your PCP in before the appointment, not after, so any lab work can happen first.
FAQ
Do I have to tell my primary care doctor about IV therapy?
You don't have to legally, but it's strongly recommended in 2026 given how many infusion types interact with medications and existing conditions. Disclosure lets your PCP catch interactions before they become problems.
Will my doctor be upset that I'm getting IV vitamins?
Most primary care doctors are neutral to supportive when the conversation is specific and evidence-based. Bring the exact formula and dose rather than a vague description, and frame it as a safety check, not a request for approval.
What labs does my doctor need before I start high-dose Vitamin C?
A kidney function panel and, in some cases, a G6PD deficiency screening are the two most relevant tests before doses above 15 to 25 grams. Ask your PCP directly which applies to your history.
Can iron infusions interact with my current medications?
Iron infusions can interact with oral iron supplements and some absorption-affecting medications. Tell your PCP about every supplement you take, not just prescriptions.
How often should my PCP know about my infusion schedule?
Update your PCP any time you start a new infusion type or change frequency significantly. A Myers Cocktail every three weeks with no changes rarely needs repeat disclosure once it's documented.
Is NAD+ therapy safe to combine with prescription medications?
NAD+ is generally low-interaction, but your PCP should still confirm this against your specific prescriptions, especially if you're on medications metabolized through the liver.
Should I ask my infusion provider to contact my doctor directly?
Yes, a physician-led infusion practice can typically send a treatment summary or speak with your PCP directly, which resolves most questions faster than relaying information secondhand.
What's the best way to explain IV therapy to your doctor in one sentence?
State the formula name, dose, and reason: for example, "I get a Myers Cocktail with 1000mg Vitamin C every three weeks for fatigue." That single sentence gives your PCP everything needed to flag a concern.
One last thing
Most patients skip the G6PD conversation entirely, and it's the one detail that actually changes a high-dose Vitamin C plan. If you've never had this screening and you're above 15 grams per session, it's worth one lab visit in 2026 before your next appointment — not because the risk is common, but because it's cheap to rule out and expensive to miss.
