I am concerned about the dosage of Gabapentin. I am a petite female, 75 years old and slight in build. Is this drug safe to take at maximum dosage for all adults regardless of age, weight and size? Am currently building up the nightly dose and have also been prescribed Trazodol to also take at night, am currently weaning off sertraline. Trying to get advice from my doctors surgery is almost impossible! I live in UK.
