Modrin Tablets: Uses, Dosage, Side Effects, Precautions and More
Modrin tablets are a prescription medicine containing nortriptyline and fluphenazine. This combination belongs to medicines used in the management of certain mental and mood-related conditions. In Pakistan, Modrin is marketed by Pharmedic Laboratories. The Drug Regulatory Authority of Pakistan (DRAP) database lists Modrin Tablet as containing nortriptyline 10 mg and fluphenazine hydrochloride 1 mg per tablet.
Because some online pharmacy listings display different strengths, patients should always check the strength printed on their own medicine pack and follow the prescription provided by their doctor.
What Are Modrin Tablets?
Modrin is a combination tablet containing two active medicines:
- Nortriptyline – a tricyclic antidepressant that affects neurotransmitters involved in mood regulation.
- Fluphenazine – an antipsychotic medicine that affects dopamine activity in the brain.
The combination may be prescribed when a healthcare professional considers both antidepressant and antipsychotic effects appropriate for a patient's condition. Modrin should not be started, stopped, or changed without medical supervision.

Modrin Tablets Uses
Doctors may prescribe Modrin for selected psychiatric or mood-related conditions. Depending on the patient's symptoms and diagnosis, it may be used in the management of:
- Depression
- Certain anxiety or tension-related symptoms
- Mood disturbances
- Psychiatric conditions requiring an antipsychotic component
- Depression accompanied by significant agitation or other symptoms requiring specialist treatment
The exact reason for prescribing Modrin varies from person to person. It is not appropriate to use this medicine simply because someone is experiencing occasional stress, sadness, or difficulty sleeping.
How Does Modrin Work?
The two ingredients in Modrin work through different mechanisms.
Nortriptyline is a tricyclic antidepressant. It primarily influences the levels and activity of neurotransmitters such as norepinephrine and serotonin, which are involved in mood and emotional regulation.
Fluphenazine is a phenothiazine antipsychotic. It primarily affects dopamine receptors in the brain and can help control certain psychiatric symptoms.
Because these medicines have significant effects on the nervous system, Modrin requires appropriate medical assessment and monitoring.
Modrin Tablets Dosage
The correct Modrin dosage depends on several factors, including the patient's diagnosis, age, symptoms, response to treatment, other medicines, and overall health.
Do not determine the dose yourself. Take Modrin exactly as prescribed by your doctor.
General precautions include:
- Take the tablet at the prescribed time.
- Swallow it with water.
- Do not take more tablets than prescribed.
- Do not double the next dose if you forget one.
- Do not stop treatment suddenly unless your doctor tells you to do so.
The strength of Modrin should also be checked carefully because different online listings may describe different formulations. The official DRAP listing identifies a formulation containing nortriptyline 10 mg + fluphenazine HCl 1 mg.
