Key takeaways
- Log a symptom in a few taps, and set it beside the doses you took.
- Use the suggested symptoms or write your own. Your record is in your words.
- Over weeks you can see whether something is settling, changing or staying the same.
- Reko does not tell you what a symptom means. For anything worrying, contact your care team.
Why record them at all
Many people on injectable medication have some side effects at some point. Which ones, how strong and for how long varies between people and between medications. For how common each one is, see the adverse reactions section of the product label, for example Mounjaro, Zepbound, Ozempic, Wegovy.
What matters for your record is simple. Memory blurs. "I felt sick last week" does not help much. "I felt sick the day after the dose went up" does.
How logging works in Reko
- Open the symptom log.
- Pick a symptom from the suggestions, or add one in your own words.
- Note how strong it was.
- Save. It sits on the same timeline as your doses.
If something unusual appears that no list would cover, you can write it in. It is your record.
Reading it back
Because symptoms and doses share a timeline, you can look for simple things:
- Does a symptom show up soon after a dose?
- Does it ease as the days go by?
- Did it change when the dose changed?
- Is it becoming less frequent?
Reko can also draw an estimated level in your system from your own doses and the compound's published half-lives. Use it as a rough picture of timing. It is an estimate, not a blood test, and it cannot say that a level caused a symptom.
Take it to your appointment
Export your record as a file, or your doses as a spreadsheet. A clear list of what happened, and when, gives your prescriber something solid to work from.
When not to wait
A record is not an alarm. If a symptom is severe, sudden or frightening, get medical help right away. Do not wait to log it.
