From the Guidelines
Drugs similar to amitriptyline for the treatment of neuropathic pain include nortriptyline, desipramine, and duloxetine, with nortriptyline being a preferred alternative due to its efficacy and lower side effect profile compared to amitriptyline 1. When considering alternatives to amitriptyline, it's essential to evaluate the condition being treated, as amitriptyline is used for various indications including depression, neuropathic pain, migraine prevention, and insomnia.
- Other tricyclic antidepressants like imipramine and doxepin may also be considered, but they may have more side effects compared to nortriptyline and desipramine.
- Selective serotonin norepinephrine reuptake inhibitors (SSNRIs) such as duloxetine and venlafaxine are also effective alternatives for neuropathic pain management, with duloxetine being a preferred option due to its consistent efficacy in painful diabetic peripheral neuropathy 1.
- The choice of alternative medication should be based on the individual patient's factors, including comorbidities, potential drug interactions, and side effect profiles.
- It's crucial to taper gradually under medical supervision when switching from amitriptyline to an alternative to avoid withdrawal symptoms.
- Side effect profiles differ between these medications, with some causing less sedation, dry mouth, or weight gain than amitriptyline, which might be beneficial depending on individual patient factors 1.
From the FDA Drug Label
Although the listing which follows includes a few adverse reactions which have not been reported with this specific drug, the pharmacological similarities among the tricyclic antidepressant drugs require that each of the reactions be considered when Imipramine Hydrochloride Tablets USP is administered Within each category the following adverse reactions are listed in order of decreasing severity. Included in the listing are a few adverse reactions which have not been reported with this specific drug. However, pharmacological similarities among the tricyclic antidepressant drugs require that each of the reactions be considered when amitriptyline is administered
Similar drugs to Amitriptyline include:
- Imipramine, due to their pharmacological similarities among the tricyclic antidepressant drugs 2, 3 These drugs share similar adverse reaction profiles and should be considered when administering either Imipramine or Amitriptyline.

Similar Drugs to Amitriptyline
- Tricyclic antidepressants (TCAs) such as imipramine, nortriptyline, and desipramine 4, 5
- Serotonin noradrenaline reuptake inhibitors (SNRIs) such as venlafaxine 5, 6
- Selective serotonin reuptake inhibitors (SSRIs) such as fluoxetine, sertraline, and paroxetine 5, 7

Mechanisms of Action
- Inhibition of presynaptic reuptake of biogenic amines such as serotonin and noradrenaline 4, 6
- Blockade of N-methyl-D-aspartate receptors and ion channels 4
- Activation of α₂-adrenergic receptors 6
- Enhancement of the descending noradrenergic inhibitory system 6
Efficacy and Safety
- TCAs have an NNT of 3.6 for achieving moderate pain relief in neuropathic pain 5
- SNRIs such as venlafaxine have an NNT of 3.1 for achieving moderate pain relief in neuropathic pain 5
- SSRIs have limited evidence for efficacy in neuropathic pain, but may have beneficial effects on well-being 5, 8
- Amitriptyline has a higher burden of side effects compared to other antidepressants, but may be more effective in certain patient populations 7
