Answer

I'll work through your four questions. First, building the two reminders and reading your profile and the FDA page in parallel.

Now reading the actual FDA Synthroid label to lock the official wording on calcium, iron, and dairy.

PDF didn't open — switching to DailyMed (the US SPL label host) and the manufacturer's HTML PI page.

That page is marketing material, not the SPL. Going to the actual DailyMed Synthroid SPL page.

Let me read deeper into the DailyMed SPL to get the exact Drug Interactions and Information for Patients sections.

eading the latest AbbVie SPL (setid 1e11ad30) which has the current FDA-approved wording.

eading the Drug Interactions section of the same DailyMed SPL with targeted search.

I have the FDA-approved Synthroid SPL wording. Now writing the visit notes with the user's verbatim questions.

Here's what happened, what the US label actually says, and what's now set up on your phone.

**Today's morning mishap — short version.** Your latte and your prenatal put calcium, iron, and dairy into the same window as your Levothyroxine. The FDA-approved Synthroid label tells you to keep those away from the dose. It does not give you a percentage absorbed, and it does not give you a recovery dose. **Don't take a second pill or a half pill on your own — the next dose is your endocrinologist or pharmacist's call.**

**What the FDA-approved US label says (DailyMed, AbbVie, label updated2024-02-20):**

From the *Highlights of Prescribing Information* on the same DailyMed page I opened:
- "Administer once daily, preferably on an empty stomach, **one-half to one hour before breakfast**."
- "Administer **at least 4 hours before or after drugs that are known to interfere with absorption**."
- "Evaluate the need for dose adjustments when regularly administering **within one hour of certain foods that may affect absorption**."
- Patient-counseling line on the same page: "Inform patients that agents such as **iron and calcium supplements and antacids can decrease the absorption of levothyroxine**."

Dairy/milk and the prenatal's calcium + iron fall in both buckets the label calls out (drug-drug with iron/calcium, drug-food with the latte on an empty stomach). The label points you away from that combination; it doesn't quantify today's loss or tell you what to do after the fact.

| Item | This turn |

| What you told me | Synthroid 75 mcg tablet once daily at 06:30 with plain water;60-min wait before breakfast; prenatal = calcium carbonate 300 mg + iron 27 mg; today: latte then prenatal15 min later |
| Match status vs your box | **name_only** — DailyMed lists 75 mcg as a Synthroid strength, but I don't see your bottle, so I can't lock to your specific NDC/box this turn |
| FDA wording on calcium/iron/dairy | quoted above |
| Missed-dose / "I already mixed them" wording | **not written** on this page — goes to your prescriber or pharmacist |
| Visit-notes file | 4 appended, 0 duplicates |

| 06:30 daily | `dae583a7-1f7c-4ce2-afce-7aaa7874eec9` | tomorrow ~06:42 PT | Levothyroxine 75 mcg — plain water only, wait 60 min before food or drink |
| 12:30 daily | `6eaac035-60a5-4899-895f-123e94495c8b` | today ~12:41 PT | Prenatal multivitamin — keep ≥4 h away from Levothyroxine |

Two things to know about those alarms: they are just calendar-clock reminders — they don't confirm you swallowed anything, and they don't enforce a strict every-N-hours interval. On a day lunch lands early, you'll need to push the prenatal later so the 4-hour separation still holds. Tell me the real workday/weekend lunch clock and I'll move it.

**What to bring to your visit (already in your visit-notes file):**
- "Did the calcium, iron, and dairy completely block my Levothyroxine absorption for today?"
- "Should I take another pill or a half dose this afternoon to make up for it, or just wait until tomorrow morning?"
- "What does the official FDA / US prescribing information say regarding calcium, iron, and dairy separation intervals?"
- "If I take Synthroid at 06:30 and the prenatal vitamin at lunch 12:30, is that a safe separation every day going forward?"

Until your prescriber or pharmacist answers: don't add a dose, don't combine two tomorrow, don't skip tomorrow. The next 06:30 alarm is just the alarm — what you do at06:30 tomorrow is a question for them.
