Viagra Super Dulox-Force (Sildenafil citrate / Duloxetine) – Patient Information

Viagra Super Dulox-Force is a combination medicine containing:

• Sildenafil citrate – a treatment commonly used for erectile dysfunction
• Duloxetine – an antidepressant medicine that also helps with certain types of chronic pain and can affect sexual wellbeing

This page explains how the medicine works, how it’s used, and important safety information. It is written for people in the United Kingdom and is designed to be easy to read.

1. Basic product information

Note: Strengths and how the tablets are taken can vary by product version. Always check the label/pack for your specific strengths and dosing instructions.

2. What is it used for (indications)?

Viagra Super Dulox-Force is used when a person needs help with sexual function and may also have related symptoms such as:

• Erectile dysfunction (ED) – difficulty achieving and/or maintaining an erection sufficient for satisfactory sexual activity
• Low mood, anxiety, or stress that may contribute to ED or reduce sexual wellbeing
• Some chronic pain conditions (because duloxetine is used for certain pain syndromes), where sexual function may be affected

Important: This medicine does not protect against sexually transmitted infections (STIs). Use appropriate protection if there is any risk.

3. How it works (mechanism of action)

3.1 Sildenafil citrate

Sildenafil belongs to a group called PDE5 inhibitors. PDE5 (phosphodiesterase type 5) breaks down cGMP, a chemical messenger that helps relax smooth muscle in the penis.

• During sexual stimulation, the body releases nitric oxide (NO).
• NO increases cGMP, improving blood flow to erectile tissue.
• Sildenafil inhibits PDE5, helping maintain higher cGMP levels.
• This supports an erection when you are sexually aroused.

3.2 Duloxetine

Duloxetine is an SNRI (serotonin–norepinephrine reuptake inhibitor). It works by changing levels of serotonin and norepinephrine in the brain and nervous system.

• May improve mood and anxiety symptoms that can worsen sexual performance
• May help with nerve-related pain in certain conditions
• Can indirectly support sexual wellbeing in people where psychological or pain factors play a role

Key point: Sildenafil still requires sexual stimulation to work effectively.

4. When you should take it (timing)

How and when you take Viagra Super Dulox-Force depends on your individual regimen and the specific strength you have.

• Typical timing for sildenafil-containing medicines: Many people take a dose about 30 to 60 minutes before sexual activity.
• Peak effect: Sildenafil’s effect often becomes stronger within the first hour, though it can vary.
• Duration: The ability to achieve an erection may last for several hours in many people.

Follow your label: Some combination regimens aim for more consistent effects throughout the day; others may be taken with planned activity. If you’re unsure, ask your pharmacist for guidance.

5. Food interactions

Food can affect how quickly sildenafil works. In general:

• Heavy, high-fat meals may slow absorption and delay onset of action.
• If you want more predictable timing, consider taking the dose on a day when you haven’t just had a very large/fatty meal.

Duloxetine absorption can also be affected by food. Many people find it easier to follow the instructions on the label (often relating to whether it should be taken with or without food).

Practical tip: If you notice the medicine is taking longer to work, track whether it was taken after a heavy meal and adjust timing accordingly (within the instructions on the pack).

6. Alcohol and medicine interactions

6.1 Alcohol

Alcohol can worsen erectile dysfunction and increase side effects such as:

• dizziness or light-headedness
• lower blood pressure
• reduced sexual performance

Moderate to heavy alcohol may significantly reduce effectiveness and increase risk of adverse effects. If you choose to drink, keep it modest and avoid binge drinking.

6.2 Medicines that can interact strongly

Some medicines must be avoided with sildenafil because the combination can cause dangerous drops in blood pressure or other serious effects.

• Nitrates (for chest pain/angina), including glyceryl trinitrate (GTN) and isosorbide compounds – avoid
• “Poppers” (amyl nitrite/amyl nitrate and similar inhaled nitrites) – avoid
• Rioliguat (for pulmonary hypertension) – typically avoid with PDE5 inhibitors

Use extra caution or seek professional advice if you take medicines that affect blood pressure, heart rhythm, or liver metabolism.

Potential interaction categories

• Alpha-blockers (e.g., for prostate enlargement) – may increase risk of dizziness/low blood pressure
• Antifungals (some azoles) and certain antibiotics – may increase sildenafil levels
• HIV medicines and anti-seizure medicines (enzyme inducers) – may reduce sildenafil levels or change duloxetine levels
• Other antidepressants, including those that increase serotonin – increases risk of serotonin-related side effects
• Triptans (migraine treatment) and linezolid (an antibiotic) – may increase serotonin syndrome risk with duloxetine
• Warfarin/anticoagulants – duloxetine can increase bleeding risk in some people
• NSAIDs (e.g., ibuprofen) – duloxetine may increase bleeding risk, especially with frequent use

Tell your pharmacist about all medicines and supplements you take, including herbal products.

7. Pharmacokinetics (how the body absorbs, distributes, metabolises, and excretes it)

Pharmacokinetics (PK) describes what the body does to a medicine. Individual results can vary depending on age, liver/kidney function, other medicines, and metabolism.

7.1 Sildenafil citrate – overview

• Absorption: Sildenafil is absorbed after oral dosing. Onset can be delayed by heavy/fatty meals.
• Time to peak: Peak blood levels typically occur within about 30–120 minutes (varies).
• Distribution: It distributes through the body and binds to plasma proteins.
• Metabolism: Mainly metabolised by CYP3A4 in the liver.
• Elimination: Excreted mostly through faeces and to some extent urine.

7.2 Duloxetine – overview

• Absorption: Duloxetine is absorbed after oral dosing; food can influence absorption speed.
• Time to peak: Peak levels commonly occur within about 6 hours (formulation dependent).
• Metabolism: Mainly processed by liver enzymes (including CYP1A2 and CYP2D6).
• Elimination: Metabolites are excreted primarily through the kidneys.

Implications for safety: People with liver impairment may have higher drug levels, increasing risk of adverse effects. Those with kidney impairment may also require extra caution.

8. Dosing guidance (how much to take)

Do not change your dose without professional advice. The correct dose depends on your age, medical history (especially heart/liver/kidney issues), current medicines, and how you respond.

General guidance:

• For PDE5 inhibitors, a “start low” approach is often used, especially if you’re older or take blood pressure medicines.
• Duloxetine dosing commonly begins at a lower level and may be increased gradually to reduce side effects.

Follow the label: Your pack should state the strength and exact instructions for your regimen.

Missed dose

• If your regimen is designed for daily dosing, take it as soon as you remember unless it’s close to the next dose.
• If the next dose is near, skip the missed dose.
• Do not double up.

Overdose

Seek urgent medical attention if you take more than the recommended amount. Symptoms of overdose can include severe dizziness, fainting, abnormal heartbeat, or severe nausea/sleepiness.

9. Safety profile: side effects and when to get help

Like all medicines, Viagra Super Dulox-Force can cause side effects. Many are mild and improve with time, but some require urgent attention.

9.1 Common side effects

• Headache
• Flushing (warmth/redness)
• Dizziness
• Indigestion or nausea
• Dry mouth
• Sleep disturbances (especially with duloxetine)
• Reduced sexual desire or sexual side effects can occur with antidepressant medicines in some people

9.2 Less common but important side effects

• Low blood pressure symptoms such as light-headedness or fainting

• Driving and machinery: Dizziness or visual changes can occur; avoid driving if you feel unwell.
• Withdrawal symptoms: Duloxetine should not be stopped suddenly. If discontinuation is needed, tapering may be required.

10. Practical use tips for best results

• Ensure sexual stimulation: Sildenafil works only when you are sexually aroused.
• Choose the right moment: If planning ahead, take the dose around 30–60 minutes before activity (adjust based on your experience and label).
• Limit heavy meals beforehand: A light meal may lead to a more predictable onset.
• Keep alcohol modest: Alcohol can reduce effectiveness and increase side effects.
• Do not exceed the dose: Taking extra does not reliably improve outcomes and increases risk of harm.
• Track response: If the medicine doesn’t work, note timing, food, alcohol, and other medicines to discuss with a healthcare professional/pharmacist.
• Address lifestyle factors: Smoking cessation, healthy weight, regular exercise, and managing stress can improve ED outcomes.
• Be cautious with conditions causing ED: Diabetes, high blood pressure, and high cholesterol are common contributors.

14. Frequently Asked Questions (FAQ)

How quickly will Viagra Super Dulox-Force work?

Sildenafil often begins to work within about 30–60 minutes, though it can be delayed by heavy or high-fat meals. Duloxetine is not typically responsible for immediate “on-the-night” effects; it may contribute to longer-term symptom management depending on the regimen.

How long does the effect last?

Sildenafil’s effects often last for several hours in many people. Individual response varies. If you notice inconsistent results, review timing, meal size, alcohol intake, and drug interactions.

Can I take it with food?

It may be possible, but food can affect absorption—especially heavy meals. Use the instructions on your product label. If you’re unsure, ask your pharmacist for tailored advice.

Can I drink alcohol when using this medicine?

It’s best to keep alcohol modest. Alcohol can worsen erections and increase dizziness or low blood pressure. Avoid binge drinking.

What should I do if I get side effects?

Many mild effects improve. If symptoms are bothersome or you develop warning signs (such as fainting, severe dizziness, chest pain, priapism, or severe allergic reaction), stop and seek medical help urgently.

Who should not use sildenafil?

People taking nitrates (including for angina) or using nitrite “poppers” should not take sildenafil due to the risk of dangerous blood pressure drops. People with certain cardiovascular conditions may need careful assessment. If you’re unsure, speak to a pharmacist.

Can I take it if I take antidepressants or migraine medicines?

Duloxetine can interact with other medicines that affect serotonin. Provide your full medicine list to your pharmacist before use, including migraine treatments (e.g., triptans), other antidepressants, and supplements.

Will it treat low mood or anxiety?

Duloxetine may help mood and anxiety symptoms, but the degree of benefit varies. If you notice mood changes, agitation, or any worsening mental health, contact a healthcare professional promptly.

What if it doesn’t work for me?

ED may have multiple causes. If it doesn’t work, avoid increasing the dose on your own. Consider discussing:

• timing and meals
• alcohol intake
• other medications that may reduce effectiveness
• underlying health factors (e.g., diabetes, cardiovascular issues)

Is it safe with other ED medicines?

Combining PDE5 inhibitors is generally not recommended. If you’re considering alternatives, seek pharmacist guidance first.

Can women or children take it?

This medicine is intended for specific adult use. It is not for children. Women’s suitability depends on individual circumstances and should be discussed with a pharmacist/healthcare professional.
