<strong>Norpramin vs. Doxepin: Which Should I Take?</strong>

If you are exploring tricyclic antidepressants, chances are you have treatment-resistant depression, haven’t responded well to first-line depression treatments like SSRIs or SNRIs, or have comorbid mental illnesses that require treatment with tricyclics.

As you are probably aware, there are many tricyclic antidepressant medications. This is because tricyclics are one of the oldest pharmaceutical treatments for depression. Though these medications all have a similar mode of action—some differences could make one a more favorable treatment than another.

Doxepin and Norpramin Are the Same Class of Medication (Tricyclics)

Norpramin and Doxepin belong to the same class of medication: tricyclic antidepressants. Each is primarily prescribed to treat depression, but they are also prescribed to treat other mental health conditions like anxiety disorders and chronic pain disorders like fibromyalgia. 

What are Tricyclics?

Tricyclic antidepressants (tricyclics) block the serotonin and norepinephrine reuptake in the brain. Serotonin and norepinephrine are neurotransmitters, or messengers, that communicate between brain cells to regulate mood and energy levels. 

Tricyclics stop the reabsorption of serotonin and norepinephrine so that more of these neurotransmitters are in the brain to account for any chemical imbalances and relieve symptoms of depression.

Unlike more recent antidepressants, like SSRIs or SNRIs, Doxepin, Norpramin, and other tricyclic antidepressants are nonselective. This means tricyclic antidepressants affect many different serotonin receptors all over the body. This differs from selective antidepressants—like SSRIs and SNRIs.

Because tricyclic antidepressants are nonselective, they can produce more side effects than SSRIs or SNRIs. Medical providers usually prescribe tricyclics when the first-line treatments do not improve depression symptoms or other mental health issues.

Doxepin and Norpramin Are Both Used to Treat Major Depressive Disorder

While Doxepin and Norpramin are used to treat major depressive disorder (MDD), characterized by sadness and apathy, they are also prescribed to treat other issues. 

What Else Does Doxepin Treat?

While Doxepin isn’t the right medication for everyone, it is primarily used to treat depression and anxiety. That said, it’s also used to treat other issues in an off-label capacity, depending on the advice of your healthcare provider.

Off-Label Uses for Doxepin

Doxepin can be used off-label to treat sleep disorders like insomnia. Off-label use means that, while the medication may be an effective part of treatment, it is not currently approved by the FDA. Because Doxepin slows brain activity, it can help you fall asleep and stay asleep. 

What Else Does Norpramin Treat?

Like Doxepin, Norpramin is approved to treat MDD, but it does have off-label uses that can be effective for some people. Because this medication has many side effects, you should always consult a healthcare specialist before taking it. 

Off-Label Uses for Norpramin

Off-label uses for Norpramin include treating:

• Bulimia nervosa
• Irritable bowel syndrome (IBS)
• Neuropathic pain
• Overactive bladder
• ADHD
• Post-herpetic neuralgia 

Doses, Dosage Form, and Side Effects of Norpramin

Understanding possible side effects and the dosing schedule can help you and your healthcare provider make the best decision about your health. 

Common Norpramin Doses and Forms

Norpramin is a tablet; an adult dose is typically between 100-200 mg daily. The dosage may be lower for elderly or adolescent patients, and Norpramin isn’t recommended for children under 12. Depending on the severity of your symptoms, your care provider may recommend increasing your dosage slowly to 300 mg per day. 

Common Norpramin Side Effects

Common side effects of Norpramin include—

• Dry mouth
• Constipation
• Blurred vision
• Dizziness
• Drowsiness
• Difficulty sleeping
• Nausea
• Weight changes

However, there are other side effects Norpramine users need to be aware of:

• Cardiovascular side effects: Norpramin can cause cardiovascular side effects such as rapid heart rate, high blood pressure, and irregular heartbeat. These side effects can be especially problematic for people with a history of heart disease.
• Anticholinergic side effects: Norpramin has anticholinergic properties, which can lead to side effects such as dry mouth, constipation, blurred vision, and urinary retention.
• Neurological side effects: Norpramin can cause neurological side effects such as confusion, agitation, tremors, and seizures. These side effects are more common in people who take high doses of the medication.
• Sexual side effects: Norpramin can cause sexual side effects such as decreased libido, erectile dysfunction, and difficulty achieving orgasm.
• Allergic reactions: In rare cases, Norpramin can cause allergic reactions such as hives, rash, itching, and swelling of the face, tongue, or throat. If you experience these symptoms, you should seek medical attention immediately.

Contact your healthcare provider immediately if you experience more serious side effects like elevated heart rate, yellowing skin or eyes, abnormal bleeding or bruising, and skin irritation or swelling.

Common Norpramin Drug Interactions

There is a risk of drug interactions when taking Norpramin, which can affect the medication’s effectiveness or increase the risk of side effects.

Here are some of the possible drug interactions with Norpramin:

• Monoamine oxidase inhibitors (MAOIs): Combining Norpramin with MAOIs can result in a potentially life-threatening condition called serotonin syndrome. This is because both medications affect the levels of the neurotransmitter serotonin in the brain, which can lead to an excessive buildup of serotonin.
• Other antidepressants: Norpramin can interact with other antidepressants, including selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors. These interactions can increase the risk of side effects, such as dizziness, confusion, and sedation.
• Antipsychotics: Norpramin can interact with antipsychotic medications, increasing the risk of side effects such as sedation, confusion, and dizziness.
• Antihistamines: Norpramin can interact with antihistamines, increasing the risk of side effects such as dry mouth, constipation, and urinary retention.
• Alcohol: Drinking alcohol while taking Norpramin can increase the risk of side effects, such as dizziness, sedation, and impaired coordination.
• Blood thinners: Norpramin can interact with blood-thinning medications, such as warfarin, increasing the risk of bleeding.
• Stimulants: Norpramin can interact with stimulant medications, such as amphetamines, increasing the risk of side effects such as agitation, anxiety, and heart palpitations.

It is essential to tell your doctor about all medications you are taking, including prescription and over-the-counter medications, herbal supplements, and vitamins, to avoid potential drug interactions. 

How Much Does Norpramin Cost?

Without insurance, 100 tablets of 100 mg of Norpramin cost around $618, depending on your pharmacy. With insurance, it could cost anywhere from $68 to $160 per 100 tablets of 100 mg. 

Doses, Dosage Form, and Side Effects of Doxepin

Doxepin, while also used to treat symptoms of anxiety and depression, comes in different forms and is administered in different doses than Norpramin.

Common Doxepin Doses and Forms

Doxepin comes as a liquid, capsule, or tablet and is taken one to three times a day. If your symptoms are less severe, your healthcare provider may prescribe 25-50 mg once a day. For more severe symptoms, the typical adult dose is 75-150 mg daily. Your provider may recommend increasing the amount to 300 mg if necessary. 

While you may feel the anti-anxiety effects soon after taking Doxepin, the antidepressant can take two to three weeks before you notice a change in your symptoms. 

Common Doxepin Side Effects

Like Norpramin, Doxepin has several common side effects, including:

• Dry mouth
• Constipation
• Blurred vision
• Dizziness
• Drowsiness
• Difficulty sleeping
• Nausea
• Weight gain

But there are other side effects of Doxepin you need to be aware of:

• Cardiovascular side effects: There is a risk of cardiovascular side effects like rapid heart rate, high blood pressure, and irregular heartbeat when taking Doxepin.
• Neurological side effects: Neurological side effects like confusion, agitation, tremors, and seizures are possible while taking Doxepin. This is more common for people on high doses of the medication.
• Sexual side effects: Doxepin can cause sexual side effects such as decreased libido, erectile dysfunction, and difficulty achieving orgasm.
• Allergic reactions: Like Norpramin, taking Doxepin can cause allergic reactions, including hives, rash, itching, and swelling of the face, tongue, or throat. This is a serious medical reaction—seek emergency medical attention immediately.
• Other side effects: Taking Doxepin can lead to other side effects, such as sweating, headache, weakness, fatigue, and vomiting.

Common Doxepin Drug Interactions

Doxepin has many similar drug interactions to Norpramin, but there are key differences.

• Monoamine oxidase inhibitors (MAOIs): Like with Norpramin, taking doxepin with MAOIs can lead to a dangerous condition called serotonin syndrome. This can occur because both medications affect the levels of the neurotransmitter serotonin in the brain, which can result in an excessive buildup of serotonin.
• Other antidepressants: Doxepin interacts with the same antidepressant medications that Norpramin does, including selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs).
• Antihistamines: Doxepin acts like an antihistamine. When you take it with other antihistamines, you increase the risk of experiencing drowsiness, dry mouth, and constipation.
• CNS depressants: Doxepin can interact with other medications that depress the central nervous system (CNS), such as benzodiazepines and opioids. This can increase the risk of side effects such as sedation, confusion, and respiratory depression.
• Alcohol: Drinking alcohol while taking doxepin can increase the risk of side effects, such as drowsiness, dizziness, and impaired coordination.
• Blood thinners: Doxepin interacts with blood-thinning medications like warfarin. This increases the risk of bleeding.
• Thyroid hormones: Doxepin can interact with thyroid hormones, potentially altering thyroid hormone levels.

How Much Does Doxepin Cost?

The cost of Doxepin varies depending on your prescribed dosage. You can expect to pay anywhere from $14.50 to $18.17 through GoodRx.com. However, if you’re paying cash without insurance, the price range can be $87 to $292. The generic form, Doxepin, is often more affordable than the brand name version: Silenor.

Do I Need a Prescription for Doxepin or Norpramin?

Yes, both Doxepin and Norpramin require prescriptions. While neither medication is a controlled substance, they are not fist-choices in treating anxiety and depression due to the number of possible side effects. If your healthcare provider does prescribe Doxepin or Norpramin, you should take it exactly as instructed. 

Other Tricyclic Side Effects

Norpramin and Doxepin are not right for everyone. They’re members of the tricyclic class and can have many side effects like serotonin syndrome, issues with pregnancy or breastfeeding, and an increased risk of bleeding.

What is Serotonin Syndrome?

While the body naturally produces serotonin, which impacts how our brain and nerves function, too much serotonin can have severe adverse effects. Serotonin syndrome occurs when your body produces too much serotonin due to a change in medication or combining certain medications.

You can experience mild symptoms like diarrhea or shivering to more intense symptoms like stiffening muscles, seizures, and fever. If left untreated, serotonin syndrome can be fatal. 

Pregnancy and Breastfeeding on Tricyclics

If you are pregnant or breastfeeding, you should always consult your doctor before taking tricyclics. In some cases, the fetus may experience withdrawal symptoms if you’ve been taking a tricyclic antidepressant during your pregnancy. Your infant should also be monitored for sleep apnea and excessive drowsiness if breastfeeding. 

Increased Bleeding Risk with Tricyclics

While tricyclics alone don’t necessarily increase your risk of internal bleeding, when combined with blood thinners like Warfarin, there is an increased bleeding risk. Because tricyclic antidepressants impact blood serotonin levels, they can contribute to abnormal bleeding.

Black Box Warning With Antidepressants

Antidepressants like Doxepin and Norpramin can cause changes in mood and behavior, like thoughts of self-harm and suicidal ideation. Contact your healthcare provider immediately if you experience a shift in how you’re feeling, what you’re thinking, or if you experience panic attacks or insomnia.
