What Is Desipramine? Uses, Dosage, and What You Need to Know in 2026

Desipramine is one of the older antidepressants still in use today, and for certain patients it remains an important option — especially when newer medications haven't worked. This guide covers what desipramine is, what conditions it treats, how it's typically dosed, and what you need to know before taking it.

What Is Desipramine?

Desipramine is a tricyclic antidepressant (TCA) sold under the brand name Norpramin (though this brand is now largely discontinued). It belongs to a class of older antidepressants that work by affecting chemicals in the brain called neurotransmitters — specifically norepinephrine and serotonin.

The FDA first approved desipramine in 1964, making it one of the longest-used antidepressants in modern medicine. Today it's considered a second- or third-line option for depression — not because it doesn't work, but because newer drugs (like SSRIs) tend to have a better side effect profile and are safer if accidentally overdosed.

What Is Desipramine Used For?

FDA-approved use:

Major depressive disorder (MDD) in adults

Common off-label uses:

ADHD (attention-deficit/hyperactivity disorder) in adults and adolescents, especially when stimulants are not appropriate

Neuropathic pain, including diabetic neuropathy and postherpetic neuralgia

Bulimia nervosa (eating disorder with binge-purge cycles)

Irritable bowel syndrome (IBS) — at very low doses

Anxiety disorders, panic attacks, and cataplexy

Depression associated with traumatic brain injury (TBI)

What Form Does Desipramine Come In?

Desipramine is available as oral tablets in the following strengths:

10 mg

25 mg

50 mg

75 mg

100 mg

150 mg

It is taken by mouth, with or without food (though food can help with nausea). It is available as a generic — brand name Norpramin is largely discontinued in the U.S.

What Is the Typical Desipramine Dosage?

Dosage is individualized by your doctor based on your condition, age, weight, and response to treatment. General guidelines:

Adults (depression): Typical dose is 100–200 mg per day; maximum is 300 mg/day for severely ill patients. Usually started low (25–50 mg) and gradually increased.

Adolescents and elderly: Usually 25–100 mg/day; maximum 150 mg/day. These groups are more sensitive to side effects.

Timing: Can be taken once daily or in divided doses. Once-daily dosing at bedtime or morning is common depending on whether the patient experiences sedation or insomnia.

Onset of effect: Partial improvement may be seen in 2–5 days; full antidepressant effects usually take 2–3 weeks.

Is Desipramine a Controlled Substance?

No. Desipramine is not a DEA-scheduled controlled substance. It does not have addiction potential and does not require any special DEA prescribing authorization. This also means it can be prescribed via telehealth without in-person visit requirements.

Key Things to Know Before Taking Desipramine

Don't stop abruptly. Stopping desipramine suddenly can cause withdrawal symptoms. Your doctor will guide you to taper down gradually.

Avoid alcohol. Alcohol combined with desipramine increases CNS depression and can be dangerous.

Tell your doctor about all medications. Desipramine has many drug interactions, including dangerous ones with MAOIs.

Get a baseline ECG if you have cardiac history. Desipramine can affect heart rhythm, and monitoring is recommended for patients with any cardiac conditions.

It may cause insomnia, not sedation. Unlike other TCAs, desipramine can be activating. If sleep problems arise, discuss timing of your dose with your doctor.
