The 75 mg lock assumes a working kidney
Pregabalin clearance tracks creatinine clearance. The capsule you swallow is mostly the capsule you will pee. When CrCl falls, the same 75 mg sits around longer and the 31% dizziness cell gets more personal.
Label bands (total daily, then split): at CLcr ≥60 mL/min the usual adult totals run 150-600 mg/day. At 30-60, those totals become 75-300. At 15-30, 25-150. Below 15, 25-75 once daily. Hemodialysis needs a supplemental dose after a four-hour run.
Brynza still names 75 mg as the site lock - the common start when kidneys are fair. Below 60 mL/min, 75 mg twice daily is often already above the trimmed band.
| CLcr (mL/min) | Example total daily band | 75 mg comment |
|---|---|---|
| >= 60 | 150-600 | 75 mg BID is a common start |
| 30-60 | 75-300 | 75 mg BID may be the ceiling, not the start |
| 15-30 | 25-150 | 75 mg once daily may already be high |
| < 15 or HD | 25-75 plus supplement | Do not guess from this table alone |
Do not invent 18.75 mg at the sink
Capsule sprinkle, if the product allows it, is still a pharmacist calculation against the table. Opening four 75 mg capsules into a week of homemade doses is not a renal adjustment.
Pharmacists may flag a mismatch. They usually cannot legally rewrite 75 mg to 25 mg without the prescriber.
- Recalculate when creatinine jumps after a loop or ACE
- Do not climb 75 mg in someone under 60 mL/min without the table
- HD supplement is extra, not instead of the daily trim
- Falls + rising creatinine - hold the step
Age, weight, sex, creatinine date
That is Cockcroft-Gault. eGFR apps can flatter thin older women. 75 mg BID is a normal-kidney start. Below 60 mL/min it is often already too much.
Bands: >=60 gives 150-600 total; 30-60 gives 75-300; 15-30 gives 25-150; <15 gives 25-75 plus HD supplement.
A new 80 mg loop or 10 mg ACE can move creatinine in a week. Recalculate before the next 75 mg step.
Intolerance at 75 mg BID that week is often the kidney, not a gabapentinoid allergy.
HD: about half off in four hours. Write the supplement. Do not take 75 mg whenever.
Do not open capsules into homemade 18.75 mg at the sink.
Pharmacists flag. They usually cannot silently cut 75 mg to 25 mg.
Falls plus rising creatinine: hold the step. Parent: pregabalin column.
EGFR apps are not always the label's tool
The US table wants Cockcroft-Gault (age, weight, sex, serum creatinine). A lab eGFR can disagree in thin older women. Using the wrong estimator is how 75 mg 'looked fine' on a printout.
Weight in the equation is why a 45 kg eighty-year-old is not a 90 kg fifty-year-old at the same creatinine of 1.2.
Loop diuretics and ACE inhibitors on the same chart (Lasix 80, Hypernil 10) change creatinine week to week. Recheck before the next pregabalin step.
Thin older women get flattered by some eGFR apps
Cockcroft-Gault wants age, weight, sex, and a dated creatinine. eGFR apps can flatter thin older women. 75 mg BID is a normal-kidney start. Below 60 mL/min it is often already too much. Labelled total-daily bands: at or above 60 mL/min gives 150-600 mg; 30-60 gives 75-300; 15-30 gives 25-150; under 15 gives 25-75 plus a hemodialysis supplement. A new 80 mg loop or 10 mg ACE can move creatinine in a week. Recalculate before the next 75 mg step.
Intolerance at 75 mg BID that week is often the kidney, not a gabapentinoid allergy. Hemodialysis removes about half in four hours. Write the supplement. Do not take 75 mg whenever a session ends and call that the whole plan. Do not open capsules into homemade 18.75 mg at the sink. Pharmacists flag. They usually cannot silently cut 75 mg to 25 mg. The prescriber rewrites.
A rehab-ward 75 mg speech fails at CrCl 28. Post-marketing includes loss of consciousness and injury. Night 75 mg plus old zolpidem is a stack. Trim one sedative at a time. Vision blur on a trimmed dose still happens. Driving remains a caution. Creatine-inflated creatinine in a gym is a clinic puzzle. Do not self-cut and do not ignore a true GFR fall.
Polish CHPL versus this US-style table: follow the dispensed leaflet when they disagree. Unchanged renal excretion stays. Edema on a trim still happens. Do not add drawer Lasix. Withdrawal after cold-stop of a high chronic dose is a different sentence from a renal hold. Falls plus rising creatinine: hold the step. Parent: pregabalin column. Lock remains 75 mg only if clearance agrees.
A new 80 mg loop can move the 75 mg math
Creatinine that sat at 1.1 can sit at 1.4 a week after morning furosemide 80 mg or Hypernil 10 mg. The Lyrica band then changes while the capsule looks the same. Recalculate before the next 75 mg step. Fog that week is often the kidney, not a new allergy. Hold the climb. Do not add drawer Lasix for Lyrica ankles on a trim. See the Lasix loop-set if the clock and the scale are also loud.
Hemodialysis cards should name the reduced daily total and the post-session add-on as two lines. Session-only 75 mg is how off days stay foggy. Nephrology writes both. This desk will not invent 25 mg from a kitchen knife. Falls at CrCl 28 after a rehab-ward 75 mg speech are the reason the table exists.
Night zolpidem plus a renal-untrimmed 75 mg is a stack. Trim one sedative at a time. Gym creatine that inflates creatinine is a clinic puzzle, not a home cut. True GFR fall is not a puzzle to ignore. Polish CHPL versus this US-style table: follow the dispensed leaflet when they disagree. Unchanged renal excretion stays either way.
Parent: pregabalin column. Titration without kidney math lives next door. Lock remains 75 mg only if clearance agrees. Tiny is relative to clearance.
Dialysis is a special 75 mg problem
About half the drug comes off in a four-hour hemodialysis. The label adds a supplement after the session on top of a reduced daily dose.
Taking 75 mg 'when I remember' on dialysis days is how Monday fog and Wednesday pain alternate. Write the session clock on the blister card.
The HD add-on is extra, not the daily plan
People who take 75 mg only after every session may be missing the reduced daily dose. The supplement is extra after a four-hour run. Take the card to nephrology. This desk will not run the equation from a blurry photo.
EGFR 58 on 75 mg BID with new fog may already sit at the top of the 30-60 band. Ask for a Cockcroft-Gault trim. Do not add a third 75 mg for pain. Tiny is relative to clearance.
If metformin 500 mg and a rising creatinine share the month, both drugs need a kidney look. If furosemide 80 mg just started, recalculate before the next Lyrica climb. Parent: pregabalin column.
Titration without kidney math lives next door. This page stays on bands, HD, and falls.
Tiny is relative to clearance
A rehab-ward 75 mg speech fails at CrCl 28. Post-marketing includes loss of consciousness and injury.
Night 75 mg plus old zolpidem is a stack. Trim one sedative at a time.

This desk will not run the equation from a blurry photo.
The AE you were trimming for
Post-marketing lists include loss of consciousness and injury. Renal impairment is named as greater AE risk.
A rehab-ward 75 mg 'tiny' speech fails when CrCl is 28. Tiny is relative to clearance.
Night falls after 75 mg plus an old zolpidem are a stack. Trim one sedative at a time under a plan.
Vision blur on a trimmed dose still happens. Driving remains a caution until the person knows their eyes.
Withdrawal after a cold-stop of a high chronic dose is a different sidebar sentence. Falls then insomnia is a messy week.
Bring age, weight, sex, creatinine date. That is the consult printout this desk wants and still will not calculate by email.
The AE you prevent by trimming
Post-marketing lists include loss of consciousness, confusion, and injury. Renal impairment is named as greater AE risk.
A '75 mg is tiny' speech fails in a rehab ward. Tiny for a 30-year-old runner is heavy for a 82-year-old with CrCl 28.
Edema on a trimmed dose still happens. Do not add 80 mg furosemide from the drawer to hide Lyrica ankles.
Creatinine jumps after Lasix or Hypernil
A new 80 mg loop or a 10 mg ACE can move creatinine enough to change the Lyrica band in a week. Recalculate before the next 75 mg step.
Intolerance at 75 mg BID in that week is often the kidney, not a 'gabapentinoid allergy'. Hold the step.
Do not add 80 mg furosemide to hide Lyrica ankles. Edema is labelled. Heart failure can worsen.
Thin older women at creatinine 1.2 are not 90 kg fifty-year-olds. Cockcroft-Gault uses weight. eGFR apps can flatter.
Dialysis days need a written supplement. '75 mg when I remember' is Monday drunk, Wednesday pain.
Pharmacists flag mismatches. They usually cannot silently cut 75 mg to 25 mg. Call the prescriber.
75 mg is only small if the clearance is
Bring age, weight, sex, and the creatinine date to the visit. That is the whole sidebar.
Ramp without kidneys: titration sidebar. Parent: pregabalin column.
