Gemcitabine + Cisplatin: what to expect, day by day

Biliary Tract21-day cycle5 effects documented

Pairs gemcitabine with cisplatin. Cisplatin needs generous IV fluids to protect the kidneys and is strongly nausea-causing; hearing and nerve changes can build up over cycles.

Gemcitabine + cisplatin on days 1 and 8, every 3 weeks (standard for advanced biliary tract cancer). Adds cisplatin's cumulative kidney, hearing, and nerve effects, and strong nausea, to gemcitabine's blood-count and flu-like effects.

Timed to the cycle

Day 1 is the day of your infusion. These are the effects a retrievable document ties to a day range for this regimen — not a prediction about you.

Flu-like syndrome

During or just after an infusion

Fever, chills, and aches within a day of the infusion that usually pass quickly; acetaminophen helps.

Neutropenia

Typically around days 7–39

A temporary drop in infection-fighting white cells.

Call your team urgently: A temperature of 100.4°F (38.0°C) or higher — an emergency.

Not tied to a cycle day

These build with the number of doses, or are measured from when treatment started, so a cycle day would be the wrong shape for them. Each keeps the timing its own source states.

Nausea and vomiting

Sickness in the first 24 hours is the "acute" phase and usually peaks 2-3 hours in; anything from 24 to 120 hours is the "delayed" phase.

Cisplatin is one of the most nausea-causing drugs, so you'll get strong multi-drug anti-nausea prevention. Nausea can be delayed, lasting a few days after treatment.

Call your team: Can't keep fluids down for more than 12 hours.

reported by about ~70% of people; severe in 5-15% · Timing from a clinical guideline · from Cisplatin

Kidney injury (nephrotoxicity)

cumulative, dose-dependent over cycles

Cisplatin can stress the kidneys, so you'll receive plenty of IV fluids before and after. It can also lower magnesium and other salts. Your team checks kidney bloodwork each cycle.

Call your team: Passing much less urine than usual, or marked swelling.

reported by about ~20-30% of people · from Cisplatin

Hearing changes (ototoxicity)

cumulative, dose-dependent

Cisplatin can cause ringing in the ears or high-pitch hearing loss that builds with cumulative dose and may be permanent. Report any new ringing or hearing change promptly.

Where this comes from

1. S1. Valle J, ABC-02 trial (gemcitabine + cisplatin, biliary) (2010) — PMID 20375404
2. S2. Cisplatin FDA prescribing information — FDA label
3. S3. Gemcitabine (Gemzar) FDA prescribing information — FDA label

Timing windows on this page rest on:

• MASCC/ESMO antiemetic consensus — emesis phases — “acute 0-24 h, delayed 25-120 h, overall 0-120 h” source
• BC Cancer Drug Manual — gemcitabine — “nadir 7-10 days, recovery within 7 days” source
• Definitional — an infusion reaction is one that occurs during or shortly after the infusion — “The timing is part of what the term denotes; there is no empirical claim here to source.”

A window appears here only where a retrievable document ties it to a drug in this regimen. Where nothing could be found, the window was removed rather than estimated — so a missing time is an honest gap, not an oversight.
