Norpramin vs. Amitriptyline: Which Should I Take?

SSRIs are the standard first line of treatment for depression, as they cause fewer side effects and have fewer health risks than other antidepressants. However, sometimes doctors choose older depression medications in cases where a patient has treatment-resistant depression.

Norpramin and amitriptyline are two medications a medical provider may suggest when a patient has treatment-resistant depression. In this article, Klarity Health takes a deeper look into these two antidepressants—we’ll explore how they work, their side effects, how much they cost, and other important details.

Amitriptyline and Norpramin Are the Same Class of Drugs

Amitriptyline and Norpramin are tricyclics. Coming into the market in 1959, tricyclics are the oldest prescription drugs used to treat major depressive disorder (MDD). They are comparably as effective as other antidepressants for treating depression. 

Though they come with many more side effects due to their mechanism of action, this characteristic makes tricyclics more effective at treating treatment-resistant depression. 

What Are Tricyclics? How Do They Work?

Essentially, tricyclics and other antidepressants help elevate the amount serotonin and norepinephrine in the brain. These neurotransmitters act as chemical messengers to allow neurons to communicate. Since people with depression are typically low in serotonin and neuropinephrine, tricyclics can effectively alleviate some symptoms of depression, anxiety, and other disorders in patients.

Newer antidepressant drugs are more selective, meaning they only affect specific receptors in the body. Selective serotonin reuptake inhibitors (SSRIs) are exactly that—selective in the receptors they block. 

Tricyclics are not selective. Because they block many different types of receptors across the body, tricyclics come with more side effects and have a lower toxicity threshold, meaning it is easier to overdose on them.

Though all tricyclics produce similar results in patients, slight differences in the chemical structures between different kinds means that each has a slightly different side effect profile.   

Amitriptyline and Norpramin for Depression

Tricyclic antidepressants are most often prescribed to treat major depressive disorders. However, medical providers may prescribe them to treat psychiatric conditions such as anxiety and neuropathic conditions like fibromyalgia or diabetic neuropathy pain. 

What Else Does Amitriptyline Treat?

In addition to treating depression, low doses of amitriptyline can help improve sleep and treat anxiety symptoms. Amitriptyline might be suitable for people with treatment-resistant depression and anxiety.

Amitriptyline is also prescribed for pain management. At low doses, it can help reduce pain associated with fibromyalgia, arthritis, and even migraines. Additionally, amitriptyline is used to treat peripheral neuropathy in diabetic patients or for individuals experiencing nerve pain. 

What Else Does Norpramin Treat?

Norpramin and amitriptyline treat similar illnesses because they work in similar ways. Like amitriptyline, Norpramin treats depression and anxiety, along with other mood disorders. It helps improve sleep quality and helps people feel more energized. 

Additionally, like amitriptyline, it helps patients manage chronic pain resulting from arthritis, fibromyalgia, or nerve pain.

It’s also advised to avoid medications used as mood regulators, such as SSRIs, and to avoid blood thinners, like aspirin or warfarin. 

Patients should stop taking MAO inhibitors 14 days before starting amitriptyline. MAO inhibitors to avoid are Isocarboxazid, Linezolid, Phenelzine, Rasagiline, Selegiline, and Tranylcypromine. 

How Much Does Norpramin Cost?

The cost of Norpramin (desipramine) depends on several factors, including dosage, your pharmacy, and whether or not you have health insurance. 90 tablets of 25 mg desipramine, the generic form, costs about $22.

Doses, Dosage Form and Side Effects of Amitriptyline

Common Amitriptyline Doses and Forms

Amitriptyline is available in tablets of 10mg, 25mg, and 50mg. It is also available in a liquid solution at three different doses: 10mg, 25mg, and 50mg. For adults, the initial dose is 50mg daily but can go as high as 150mg. 

This medication can cause sleepiness and should be taken at night before bed. 

Amitriptyline Side Effects

Some common side effects seen when taking amitriptyline include: 

• Constipation 
• Nauseous and vomiting 
• Feeling sleepy, fatigued, or tired

Common Amitriptyline Drug Interactions

You must provide your healthcare provider with a complete list of all medications and supplements you are currently taking. Amitriptyline should not be taken alongside thyroid supplements, medications that treat bleeding disorders, NSAIDs (like ibuprofen or naproxen), medications for high blood pressure, and antidepressants like SSRIs. 

Patients should stop taking MAO inhibitors 14 days before starting amitriptyline. MAO inhibitors to avoid are Isocarboxazid, Linezolid, Phenelzine, Rasagiline, Selegiline, and Tranylcypromine. 

How Much Does Amitriptyline Cost?

Any medication’s exact cost might differ depending on your insurance, dosage, and pharmacy. But to give you a rough estimate, a 25mg amitriptyline oral tablet would cost around $14 for 28 tablets. 

Other Tricyclic Side Effects

Due to the chemicals serotonin and norepinephrine increasing, their levels in the brain might get dangerous. While taking this medication can cause certain side effects that can be detrimental to your health. 

What is Serotonin Syndrome?

When the brain absorbs too much serotonin, it can cause a serious condition called serotonin syndrome. This occurs when the brain is deeply saturated and heavily built up with serotonin. Some symptoms you could experience include high fevers, agitation, palpitations, and muscle rigidity. 

Pregnancy and Breastfeeding on Tricyclics

There has not been enough research to determine if taking tricyclics is safe during pregnancy. It should be avoided if possible and advised only to take it during the first trimester to avoid any risk to your baby. However, it’s recommended not to take tricyclics while breastfeeding since it does transfer into breast milk and can potentially harm nursing infants. 

Increased Bleeding Risk With Tricyclics

There is a significant risk of bleeding while taking tricyclics with other medication for blood, like warfarin. However, it’s okay if you are only taking tricyclics alone. Patients are advised to avoid taking blood thinners or aspirin if they can. If their underlying condition is not compensable, it’s best to avoid getting treatment with tricyclics.
