Hello,
Welcome to Healthcare Magic.
I have read your question fully and understand your concerns.
Instead of
gabapentin, you could try
Pregabalin. Start with 75 mg once a day and then increase it to 75 mg twice a day. Based on pain relief, you could increase the dose up to a maximum of 300 mg twice a day. As you have tolerated gabapentin well, you should not find much difficulty in tolerating Pregabalin too.
Another option is Amitriptyline; you could start at the smallest dose of 10 mg at bed time. Based on pain control, gradually increase to 50 mg at night. If you are still able to tolerate without side effects, you could go up to maximum of 75 mg at night. Side effects from Amitriptyline are
dry mouth, sedation, gastric upset, light headedness etc. Many people are able to tolerate lower doses well.
Both the tablets are prescription only medications, hence you would need to see a doctor for the prescription.
I hope this answer has helped you.
Thank you
Regards
Dr Sunita Sayammagaru
