01 The 400 mg capsule is not a day-1 TID
If the bottle is 400 mg and the diagnosis is PHN, a clinician can still start with one capsule a day or use 100/300 mg capsules to build the insert's 300 mg steps. What they should not do is hand you 400 mg three times tomorrow because the pain is loud. Sedation and ataxia show up early. Pain benefit is a later paragraph.
Epilepsy starts differently - often 300 mg three times in adults - and stops differently (at least a one-week taper). Do not copy a pain ramp onto a seizure medicine or the reverse.
The gabapentin leaf locks 400 mg as the capsule. This margin is the ramp.
02 When sedation means stop climbing, not climb at night
Falls, a slump in a chair, or a new opioid the same week: call, do not add the third 400 mg. The pair raises respiratory-depression risk.
Mood change, spreading rash, or shoes that do not fit: call, do not uptitrate. DRESS is uncommon and urgent. Edema is common enough to mention.
If sedation is the limiter, the answer may be a slower ramp or a renal row, not a bedtime pile. Check creatinine. The renal ink is that file.
Alcohol is extra. A leftover benzodiazepine is extra. The warning is a class, not a brand.
Strength out-of-stock is not a reason to jump. Write the first-three-days total on paper.
03 Pain spikes versus a scheduled 400 mg capsule
Gabapentin for PHN is scheduled. As-needed 400 mg is how people take 1200 mg by evening and fall. A spike tablet is usually another INN if they wrote one.
Epilepsy ramps and tapers are a different paper. Do not copy a pain stop onto a seizure medicine. Minimum one-week taper when this is antiseizure.
Do not add a drawer muscle relaxant on day two. Sedation stacks.
If 400 mg arrived because 300 mg was out, say so at the next visit. The climb may have been steeper than intended.
Elise kept the PHN 300 mg steps. Mail us if we treated 400 mg TID as a day-1 default.
04 How to write the first three days when the bottle is 400 mg
Ask for a daily total, not only "start the 400s." Day 1 may be one capsule. Day 2 may still not be three. PHN's insert climb is 300 mg-shaped. A 400 mg bottle can still go slow if they write it.
Space capsules if the day has more than one. Do not pile them at 22:00 to sleep through dizziness.
Separate aluminum or magnesium antacids by about two hours. Food is otherwise fine.
Opioids already on the chart need a plan before the ramp, not after a chair nap. See the leaf warning.
Horizant and Gralise are other products. Do not convert them into this climb.

06 Mood, rash, edema: the ramp is not a dare
New suicidal thinking, a spreading rash, or swelling that changes shoes - call, do not uptitrate. Peripheral edema is common enough to mention. DRESS is uncommon and urgent.
If the 400 mg capsule arrived because 300 mg boards were out, say so. Strength availability is not a titration plan.
07 Sedation means stop climbing, not climb in the dark
Falls, a slump in a chair, or a new opioid the same week: call, do not add the third 400 mg. The pair raises respiratory-depression risk.
Mood change, spreading rash, or shoes that do not fit: call, do not uptitrate. DRESS is uncommon and urgent. Edema is common enough to mention.
If sedation is the limiter, the answer may be a slower ramp or a renal row, not a bedtime pile. Check creatinine. The renal ink is that file.

08 Do not pile the day's capsules at 22:00
People move all three 400 mg capsules to bedtime to "sleep through" dizziness. That is a peak, not a strategy. It is also how a chair nap becomes a respiratory event if an opioid is already on board.
Alcohol is extra. So is a leftover benzodiazepine. The labeled warning is about CNS depressants as a class.
If sedation is the limiter, the answer may be a slower ramp or a renal row, not a bigger bedtime pile.
| Ramp idea | Why it fails |
|---|---|
| 400 mg TID on Monday | Skips the PHN 300 mg steps |
| Three capsules at 22:00 | One peak, more falls, more respiratory risk with opioids |
| Add oxycodone for the leftover pain on day 2 | Labeled combo warning |
| Antacid with every capsule | Absorption drops; separate ~2 hours |
09 How to ask for a daily total when the bottle that arrived is 400 mg
Ask for a daily total, not only "start the 400s." Day 1 may be one capsule. Day 2 may still not be three. PHN's insert climb is 300 mg-shaped. A 400 mg bottle can still go slow if they write it.
Space capsules if the day has more than one. Do not pile them at 22:00 to sleep through dizziness.
Separate aluminum or magnesium antacids by about two hours. Food is otherwise fine.
Opioids already on the chart need a plan before the ramp, not after a chair nap. See the leaf warning.

10 Climb in printed steps, not in pain decibels
Ask for a daily total before the first 400 mg capsule. Reviewed 21 August 2026, Bordeaux.
Ask for a daily total before the first 400 mg capsule. PHN climbs are 300 mg-shaped. A 400 mg bottle can still go slow. Space capsules. Do not pile three at 22:00. Separate aluminum or magnesium antacids by about two hours.
Sedation, a new opioid, a spreading rash, or shoes that do not fit: stop climbing and call. Check creatinine if a previously tolerated capsule suddenly knocks you into a chair. The renal ink reprints the rows.
As-needed 400 mg is not a PHN plan. Epilepsy tapers want at least a week. The leaf locks 400 mg as a capsule strength. Mail [email protected] if we treated 400 mg TID as a day-1 default.
Two capsules on day 1 because the pain was loud already skipped a 300 mg shape. Say the extra before this morning's swallow. If you are sedated, hold until they answer. Do not add oxycodone tonight. A kitchen third of a 400 mg capsule is a messy 300 mg. Ask for 300 mg capsules or the solution if that is the plan.
When PHN and epilepsy share one bottle, the seizure paper owns the taper and usually the climb. Do not copy a pain stop onto an antiseizure medicine. Ask them to write one daily total. A Friday pain-style stop is how status gets written up. Horizant and Gralise stay on their own food rules.
Write the first-three-days total on paper when 300 mg is out of stock. Strength availability is not a titration plan. Alcohol and a leftover benzodiazepine are extra. The warning is a class, not a brand.
Therapy-day-only 400 mg is a spike plan. Unless they wrote it, you will stack with scheduled capsules on those days. Ask for a scheduled total that already includes therapy days. Kidneys still own the daily amount. A therapy day is not a renal holiday. Falls during a climb are a reason to stop climbing, not a reason to move all three capsules to bedtime.
Opened powder plus juice on a child's tray is how a 400 mg unit becomes a sweet accident. Ask about the oral solution if swallowing is the problem. Do not mix opened powder with an antacid at the same minute. Mood change during a climb is a call, not an uptitration. DRESS is uncommon and urgent.
If you are not sedated on day 3, that is not a license to land on 1200 mg. Ask them to write the next daily total. Elise kept the PHN 300 mg steps so 400 mg TID would not look like a day-1 default.
Horizant and Gralise stay other products. Do not convert those food-rule tablets into this Neurontin 400 mg climb.
