What is a Side-Effect Log?

What goes in a side-effect log

The log works because every entry holds the same few fields. At minimum:

• The date: one line per day, so gaps are visible too.
• The symptom: named the same way each time, from a short list you choose up front.
• A rating on a simple scale: for example 0 to 3, where 0 is none and 3 is severe.
• What else changed that day: a new dose, a missed or held dose, or a change in eating or drinking. This is the context a prescriber needs to read the rating.
• A short note: anything that doesn't fit a number, in a few words.

The log is general to any medication. One example is a side-effect log kept for a GLP-1 (glucagon-like peptide-1) prescription: the person records each dose as taken, missed or held, rates a handful of symptoms each day, and notes their intake, so that the weeks line up with the dose they were on.

Why a consistent scale matters

A rating is only useful if it means the same thing every day. If a 2 in the first week means "noticeable" and a 2 in the sixth week means "I stayed in bed," the pattern is noise. Write down what each number means once, in your own words, and keep it. Keep the symptom list short too: a few symptoms rated daily beats a long list rated when you remember.

How a weekly roll-up shows the pattern

Daily entries are the raw material; the weekly total is what you read. Adding up each symptom's ratings by week, and putting the dose in force beside each week, lets you see which weeks had higher ratings and what had changed going into them. That is a fact about your own record. What it means is a question for your prescriber, not a conclusion to draw yourself.

Bringing it to an appointment

Appointments are short. Bring the period since your last visit as one page: doses taken, late, missed or held; any dose changes with their dates; the days a symptom was rated high; and your own questions, written down while you remembered them. If a symptom gets worse between visits, contact your prescriber or pharmacist, and seek urgent care for severe symptoms. Your medication's FDA Medication Guide and prescribing label list its known side effects. To set up your own log, see what to record between GLP-1 appointments.

Own the log, don't rent it

A side-effect log is a record of your own health history, so it is worth keeping in a file you control, on your own computer or in your own Google account, rather than in a service you rent. The GLP-1 Tracker & Peptide Log is a one-time-purchase Excel and Google Sheets workbook that lines up each week's dose in force against that week's side-effect totals and puts any date range on a one-page Visit Summary. To try the habit first, the free dose and side-effect log is a single tab for one medication, pre-filled with an example.

A note on what this is

A side-effect log records what happened; it does not suggest doses, judge whether a symptom is expected, or replace your prescriber or pharmacist. This page is general information, not medical advice.
