Dejac T

Last Updated on 11/05/2026 ✔ Medically Reviewed by Dr. Arjun Srivastav

Dejac T is a combination tablet listed with tadalafil and dapoxetine as its active ingredients. Each tablet is identified as containing tadalafil 10 mg and dapoxetine 30 mg. The product is marketed under the Intas Pharmaceuticals name. Its composition brings together two different classes of medicines, each with a separate pharmacological profile.

Before considering this combination, it is important to understand its ingredients, product information, potential interactions, and relevant safety restrictions. Product-specific prescribing instructions should be verified rather than assumed from the individual ingredients.

What Is Dejac T?

Dejac T is an oral combination medicine listed with two active ingredients, tadalafil and dapoxetine. It is available in 10 mg and 30 mg strengths, respectively, according to current product listings.

The product is associated with Intas Pharmaceuticals Ltd and is commonly listed in a strip containing four tablets. Its two ingredients belong to different medicine classes. Tadalafil is a phosphodiesterase type 5 inhibitor, while dapoxetine belongs to the selective serotonin reuptake inhibitor class.

These ingredients have different pharmacological properties and separate prescribing considerations. Their presence in one tablet makes it particularly important to review the combination rather than treating its ingredients as interchangeable medicines.

Dejac T Product Information

The information above reflects the product listings reviewed. The physical packaging and manufacturer documentation should be used to confirm the details of the actual product supplied.

Dejac T Ingredients and Their Functions

Dejac T composition combines two active compounds working in different systems within the body.

Tadalafil and Its Role

Tadalafil belongs to the PDE5 inhibitor drug class. It prevents the breakdown of cyclic GMP in smooth muscle tissue. This action promotes arterial relaxation and penile blood flow during sexual arousal. It requires natural stimulation to function and does not alter ejaculation timing.

Dapoxetine and Its Role

Dapoxetine is a fast-acting selective serotonin reuptake inhibitor. It increases serotonin concentrations at neural synapses in the brain. This neurochemical change delays the ejaculatory reflex. Because it acts quickly, it is designed for targeted use rather than daily antidepressant therapy.

Why Are Both Ingredients Combined?

Combining tadalafil 10 mg and dapoxetine 30 mg into one tablet treats two distinct physiological processes at once. Vascular flow controls erection firmness, while brain serotonin levels influence ejaculatory timing. A single combination tablet offers convenience, but requires screening for risks linked to both drug classes.

What Is Dejac T Used For?

Product listings associate Dejac T with male sexual health and premature ejaculation. Its composition includes two ingredients that have different pharmacological classifications.

Erectile Dysfunction

Erectile dysfunction is a term used for persistent difficulty achieving or maintaining an erection. Tadalafil belongs to the PDE5 inhibitor category of medicines.

The presence of tadalafil in the product identifies its ingredient classification. However, the inclusion of tadalafil in a combination tablet should not be interpreted as independent confirmation of the suitability or safety of that combination for someone with erectile dysfunction.

Premature Ejaculation

Premature ejaculation refers to ejaculation occurring sooner than desired, often accompanied by difficulty controlling its timing.

Dapoxetine is the ingredient associated with the premature ejaculation treatment category. Its prescribing information includes specific requirements concerning patient assessment, other medicines and contraindications.

When Both Concerns Occur Together

Erectile dysfunction and premature ejaculation are separate sexual health concerns. Their assessment involves different clinical considerations.

A product containing tadalafil and dapoxetine should not be assumed to be appropriate simply because both ingredients appear in its composition. The relevant prescribing restrictions must be considered before any treatment decision.

How Does Dejac T Work?

Dejac T combines vascular enzyme inhibition with central nervous system modulation.

Tadalafil blocks PDE5 enzymes to keep cyclic GMP active, maintaining smooth muscle relaxation and penile blood inflow. At the same time, dapoxetine blocks serotonin reuptake in the brain, delaying ejaculatory signals. This dual action targets physical firmness and neurological control without acting as an automatic enhancer.

How to Take Dejac T

Product-specific administration instructions should be confirmed using the manufacturer’s documentation and an appropriate prescribing reference.

The instructions for individual tadalafil and dapoxetine medicines should not automatically be combined to create a dosing schedule for Dejac T.

Before any administration decision, the following product information requires verification:

• The correct active ingredient strengths.
• The manufacturer’s instructions for the finished combination.
• The prescribed administration frequency.
• Relevant contraindications and medicine interactions.
• Whether the combination is appropriate under the applicable prescribing guidance.

Do not independently establish an administration schedule based on instructions for either ingredient alone. The product packaging and appropriate professional advice should take precedence over general information about individual medicines.

Dejac T Dosage and Important Precautions

The listed tablet strength is tadalafil 10 mg combined with dapoxetine 30 mg. This describes the composition of the product, not an individual dosing recommendation.

There is an important distinction between identifying a tablet strength and establishing a suitable dosage. Product strength alone does not provide sufficient information to determine whether a medicine combination is appropriate for a particular person.

The Australian prescribing information for dapoxetine includes specific restrictions concerning PDE5 inhibitors. Consequently, the presence of tadalafil in Dejac T requires particular attention when reviewing the relevant safety information.

Do not assume that the dosage instructions for dapoxetine alone establish an appropriate schedule for this fixed combination.

Dejac T Side Effects

Dejac T side effects range from mild discomfort to severe medical issues. Tadalafil is one of the listed ingredients in Dejac T, so it is important to understand the possible reactions associated with this component. This guide to tadalafil side effects provides further information about common reactions and symptoms that may require medical attention.

Drug Interactions and Safety Considerations

The interaction profiles of tadalafil and dapoxetine need to be considered separately. A medicine that interacts with one ingredient may require additional review when both are present in the same tablet.

Medicines That Can Interact With Tadalafil

Relevant medicine groups include:

• Nitrate medicines.
• Riociguat.
• Alpha blockers.
• Certain blood pressure medicines.
• Medicines that affect CYP3A4 activity.

These groups have different interaction considerations. Nitrate medicines and riociguat are particularly important in tadalafil prescribing information.

Medicines That Can Interact With Dapoxetine

Dapoxetine prescribing information identifies interactions involving:

• Monoamine oxidase inhibitors.
• Other SSRIs and SNRIs.
• Tricyclic antidepressants.
• Other serotonergic medicines.
• Certain CYP3A4 inhibitors.
• Some medicines affecting serotonin metabolism.

A complete medicine history is important when reviewing dapoxetine-related interactions.

Alcohol and Other Substances

Alcohol is specifically addressed in dapoxetine prescribing information because of concerns involving dizziness, drowsiness, impaired judgement and fainting.

Other substances and medicines can also affect the safety profile of dapoxetine. These should be disclosed during a medicine review.

Who Should Avoid Dejac T?

Suitability cannot be established from the product name or tablet strength alone.

The prescribing information for dapoxetine and tadalafil identifies several medical circumstances and medicine interactions that require particular attention. These include relevant cardiovascular conditions, certain liver conditions, a history of fainting and the use of contraindicated medicines.

People taking nitrates, riociguat, antidepressants or other medicines with relevant interaction potential should not rely on a general product description to determine suitability.

A healthcare professional should review the individual ingredients, relevant prescribing restrictions and the person’s existing medicines before any decision involving this combination.

Dejac T vs Tadalafil and Dapoxetine Separately

The main difference is the way the ingredients are presented.

A fixed combination and two separately supplied medicines are not automatically interchangeable. Their prescribing considerations, ingredient strengths and interaction restrictions need to be assessed independently.
