Dejac-T (Tadalafil/Dapoxetine)

Product Overview

Dejac-T is a prescription medication intended for adult men with erectile dysfunction (ED) and premature ejaculation (PE). Produced by Intas Pharmaceuticals Ltd, each strip contains four film‑coated tablets, each delivering 10 mg Tadalafil and 30 mg Dapoxetine. Available pack sizes of 32, 60, or 92 tablets allow flexible dosing for short‑term or ongoing therapy. The product ships within six to fifteen days depending on location. Dejac-T is taken orally before sexual activity, offering a combined approach to improve erectile rigidity and extend ejaculatory control. The formulation is manufactured under Good Manufacturing Practice (GMP) standards and complies with international pharmacopeial specifications. Proper storage at room temperature away from moisture and heat is recommended. Patients should keep the medication out of reach of children and avoid exposure to excessive heat, which can degrade the active ingredients.

What is Dejac-T

Dejac-T is classified as a combination therapy for ED and PE in adult men. It contains Tadalafil, a phosphodiesterase‑5 inhibitor that enhances blood flow to the penis, and Dapoxetine, a short‑acting selective serotonin reuptake inhibitor that delays ejaculation. The fixed 10 mg/30 mg dose ensures consistent exposure of both agents, supporting simultaneous improvement in erectile function and ejaculatory latency. The product is manufactured under strict GMP conditions and meets regulatory standards set by the Indian Central Drugs Standard Control Organization as well as international quality benchmarks. The medication is not indicated for use in women or children and should be kept out of reach of minors. It is also contraindicated in patients with severe cardiovascular disease or those taking nitrate medications, due to the risk of hypotensive events. Patients should consult a healthcare professional before initiating therapy.

Uses and Benefits

The primary advantage of Dejac-T is its ability to treat both ED and PE with a single tablet, simplifying regimens and improving adherence. Clinical data indicate that men using the combination experience higher scores on the International Index of Erectile Function and longer intravaginal ejaculatory latency time compared with placebo. The once‑daily dosing can be taken about thirty minutes before sexual activity, providing flexibility while maintaining a predictable pharmacokinetic profile. In addition, the dual mechanism may reduce performance anxiety, fostering greater confidence and satisfaction in intimate relationships. Patients often report enhanced overall sexual satisfaction and a lower likelihood of needing separate medications for each condition. The medication should not be used more than once per day, and patients are advised to avoid excessive alcohol consumption, which may increase the risk of side effects.

How It Works

The mechanism of action of Dejac-T involves two complementary pathways. Tadalafil blocks phosphodiesterase‑5, leading to increased cyclic guanosine monophosphate (cGMP) in penile tissue, which promotes smooth muscle relaxation and vasodilation, thereby facilitating a firm erection when sexual stimulation occurs. Dapoxetine acts as a short‑acting SSRI, modulating central serotonin receptors to delay the ejaculatory reflex and extend the time to orgasm. Together, these effects enable men to achieve and maintain an erection while controlling the timing of ejaculation, addressing both aspects of male sexual dysfunction simultaneously. Tadalafil’s pharmacologic effect can persist for up to 36 hours, while Dapoxetine reaches peak plasma concentrations within one to two hours, providing a rapid onset of action for premature ejaculation. This combined profile supports spontaneous sexual activity over an extended window, enhancing overall sexual confidence.

Dosage Guidelines

Adult men should take one Dejac-T tablet orally with water approximately 30 to 60 minutes before anticipated sexual activity. The standard dose is one tablet per day; however, dosage may be adjusted based on individual response, tolerability, and comorbid conditions. Patients with mild hepatic impairment are generally advised to remain at the standard dose, while those with moderate impairment should consult a physician before use. The medication must not be taken more than once within a 24‑hour period, and it should be avoided with heavy or fatty meals that could delay absorption. Alcohol intake should be limited, as it may increase the risk of dizziness or hypotension. Proper storage at room temperature away from moisture and heat preserves potency. Patients should inform their healthcare provider of all current medications, especially nitrates or alpha‑blockers, to prevent serious interactions. For detailed prescribing information, refer to the FDA.

Side Effects

Like all pharmaceuticals, Dejac-T may cause adverse effects, most of which are mild and transient. Common side effects include headache, facial flushing, dizziness, nausea, and mild visual disturbances such as blurred vision or color tinting. Some users report back pain, muscle aches, or a runny or stuffy nose. Less frequently, the drug can cause orthostatic hypotension, arrhythmias, or priapism — a prolonged erection that requires immediate medical attention. Rare but serious events, such as sudden hearing loss or severe cardiovascular complications, have been reported in post‑marketing surveillance. Patients experiencing chest pain, severe shortness of breath, or signs of an allergic reaction (e.g., swelling of the face, lips, or throat) should discontinue use and seek emergency care. Additionally, some patients may experience gastrointestinal discomfort or mild skin rash; these symptoms typically resolve without medical intervention.

Warnings and Precautions

Dejac-T is contraindicated in individuals with known hypersensitivity to Tadalafil, Dapoxetine, or any excipients of the formulation. The medication should not be used by patients taking nitrate derivatives (such as nitroglycerin or isosorbide dinitrate) or certain alpha‑blockers, as the combination can precipitate a dangerous drop in blood pressure. Men with severe cardiovascular disease, recent myocardial infarction, stroke, or uncontrolled hypertension are advised to consult a physician before initiating therapy. The drug is not intended for use in women or children and must be stored out of reach of minors. Patients should disclose all current medications, including over‑the‑counter products and herbal supplements, to avoid potential drug interactions. Proper medical supervision is essential to ensure safe and effective use. For more detailed safety information, see the NIH.

Frequently Asked Questions

Question 1: Can Dejac-T be taken with food?

Answer: Dejac-T can be taken with or without food; however, a heavy, high‑fat meal may delay the onset of action of Tadalafil, so it is advisable to take the tablet on an empty stomach or with a light meal for predictable absorption.

Question 2: How long does the effect of Dejac-T last?

Answer: The effect of Tadalafil can last up to 36 hours, while Dapoxetine’s action is shorter, typically a few hours. This means a single dose can support spontaneous sexual activity over a broader window, but the ejaculatory control benefit diminishes as drug levels decline.

Question 3: Is a prescription required to purchase Dejac-T?

Answer: Yes, Dejac-T is a prescription‑only medication; a qualified healthcare professional must evaluate a patient’s medical history and current health status before prescribing it to ensure safe use.

Question 4: Can I use Dejac-T if I have hypertension?

Answer: Men with hypertension can use Dejac-T only after consulting a physician, especially if they are on antihypertensive drugs, because the combination may affect blood pressure control.

Question 5: Where can I find more detailed prescribing information?

Answer: Comprehensive prescribing information, including contraindications, adverse reactions, and drug interaction tables, is available in the product’s package insert and online resources such as the NIH, FDA, MedlinePlus, and Drugs.com.
