How to take gabapentin tablets

How to take gabapentin capsules
Swallow the capsule whole with a glass of water. Do not open, crush, or chew it.
If it’s too difficult to swallow the capsule, the patient or a caregiver can carefully open it, sprinkle the contents into a small cup of water, juice, or apple sauce, and give the dose that way.
How to take gabapentin oral solution
Shake the closed bottle well before each use.
Measure the oral liquid with a syringe or medicine cup with millimeter markings. Gabapentin oral suspension usually comes with a 12 ml dosing syringe.
Remove the child-proof cap from the bottle.
Make sure the syringe adapter has been pushed into the bottle opening. If not, fully insert the syringe adapter into the bottle opening.
Push the syringe plunger all the way down to the tip.
Insert the syringe tip into the adapter.
Turn the bottle and syringe upside down.
Slowly draw out enough liquid to the correct milliliter mark.
Turn the bottle back to the upright position.
Remove the syringe and place the tip in the mouth.
Slowly empty the contents into the mouth and swallow.
Securely fasten the child-safety cap back on the bottle.
If you miss a dose of gabapentin, take the missed dose as soon as you remember. Take the next dose at its scheduled time. If it is almost time for the next dose, skip the missed dose and take the next dose at its scheduled time. Do not take extra medicine to make up for a missed dose.
If you are taking gabapentin for seizures, ask your doctor or pharmacist for directions on how to handle a missed dose.
