Basic Product Information

How Assurans Works (Mechanism of Action)

Assurans is a PDE5 inhibitor. In the body, nitric oxide released during sexual stimulation increases levels of cGMP (cyclic guanosine monophosphate) in penile tissue. cGMP relaxes smooth muscle in blood vessels, allowing increased blood flow.

PDE5 is an enzyme that breaks down cGMP. Sildenafil blocks PDE5, which helps maintain higher cGMP levels for longer.

• For erectile dysfunction: Assurans helps improve the ability to achieve and maintain an erection in response to sexual stimulation.
• For pulmonary arterial hypertension: Assurans helps relax pulmonary blood vessels, which can improve exercise capacity and reduce symptoms in appropriate patients.

Important: Assurans does not automatically cause an erection without sexual stimulation. It supports the normal physiological response to arousal.

Pharmacokinetics (How the Body Handles Sildenafil)

Pharmacokinetics describes absorption, distribution, metabolism, and elimination. While individual responses vary, the following provides a general picture:

• Absorption: Sildenafil is absorbed after oral dosing. Peak levels typically occur within about 30 to 120 minutes (faster for many people with fasting conditions).
• Onset: Some effect may be felt within 30–60 minutes.
• Duration: Effects can last for around 4 hours for many people, though some may experience a shorter or longer window.
• Metabolism: The liver primarily metabolises sildenafil via CYP450 pathways (notably CYP3A4).
• Elimination: Mostly excreted as metabolites via faeces and urine.

Because metabolism relies on liver enzymes, drug interactions that affect CYP3A4 can change sildenafil levels in your body.

Typical Use and Indications

Assurans may be used for:

• Erectile dysfunction (ED): Helping men achieve and maintain an erection when sexual stimulation is present.
• Pulmonary arterial hypertension (PAH): A condition involving high blood pressure in the lungs where sildenafil may improve symptoms and exercise tolerance in selected patients.

Not for: Assurans is not intended for everyone. It should not be used for conditions not listed on the product information or outside clinician guidance for PAH.

Timing: When to Take Assurans

For erectile dysfunction:

• Take Assurans about 30–60 minutes before sexual activity.
• In some cases, it may be effective even earlier or later depending on factors such as food intake and individual metabolism.
• A typical dosing schedule is once per day only when needed—avoid taking more frequently than advised.

For pulmonary arterial hypertension (PAH):

Timing and dosing follow specific schedules based on the prescribed regimen and product instructions.

Dosing (General Guidance)

Dosing depends on the indication, age, kidney/liver function, and drug interactions. The information below is general and should be matched to the product strength and your healthcare plan.

• ED: Common starting doses are often lower (e.g., 25 mg or 50 mg) for many adults, then adjusted based on response and tolerability.
• Maximum frequency: Do not exceed the maximum dosing frequency stated in the product information. Many regimens are limited to one dose per day for ED.
• PAH: Doses are typically divided across the day and carefully titrated according to clinical response.

Missed dose: If used for ED, there is usually no “missed dose” because it’s taken before sex. If used for PAH, follow the dosing schedule in the product information or the instructions provided.

Kidney/liver impairment: Lower doses may be needed for some patients. Ask a pharmacist if you have liver disease or significant kidney impairment.

Food Interactions and Effects of Meals

Food can influence how quickly sildenafil reaches peak levels.

• High-fat meals: May delay absorption, meaning it could take longer to work.
• Fasting or light meals: Often lead to faster onset for many people.

Practical approach: If you’re trying sildenafil for the first time, consider testing on an occasion where you have eaten a moderate or lighter meal, or plan to give more time after a heavy meal.

Alcohol and Sildenafil Interactions

Alcohol can make ED symptoms worse by reducing arousal and affecting blood flow and coordination. It can also increase the likelihood of side effects such as dizziness or low blood pressure.

• Moderate alcohol may still be tolerated by some people, but tolerance varies.
• Heavy drinking may increase side effects and reduce effectiveness.

Safety note: Avoid driving or operating machinery if you feel dizzy, lightheaded, or unwell after taking Assurans—especially if you’ve had alcohol.

Medicine Interactions (Very Important)

Certain medicines can dangerously interact with sildenafil, most importantly medicines that contain nitrates.

1) Nitrates and “nitric oxide” medicines

Do not use sildenafil with nitrates. This includes prescription or recreational nitrates and nitrate-containing heart medicines.

• Examples include glyceryl trinitrate (GTN), isosorbide dinitrate, and isosorbide mononitrate.
• Also avoid combinations with poppers or other nitrate-like substances.

Combining sildenafil with nitrates can cause a significant drop in blood pressure.

2) Riociguat

Riociguat (for pulmonary hypertension) must not be taken with sildenafil because it can also increase the risk of marked hypotension.

3) Alpha-blockers (for prostate/urinary symptoms or blood pressure)

Some men take alpha-blockers such as tamsulosin or doxazosin. The combination may increase dizziness or low blood pressure, particularly when starting or adjusting doses.

• Use caution and consider spacing doses as advised by a clinician.
• Start with lower sildenafil doses if recommended.

4) Strong CYP3A4 inhibitors

Medicines that strongly inhibit CYP3A4 can raise sildenafil levels and increase the chance of side effects.

• Examples may include some antifungals (e.g., ketoconazole, itraconazole) and some HIV protease inhibitors.

5) CYP3A4 inducers

Some medicines reduce sildenafil levels, potentially making it less effective.

• Examples include rifampicin and some anticonvulsants (depending on specific drugs).

6) Other PDE5 inhibitors

Avoid taking sildenafil with other ED medicines of the same class (e.g., tadalafil or vardenafil) at the same time.

7) “Nitrate-like” recreational drugs

Certain recreational products marketed for sexual enhancement can contain substances that act like nitrates or PDE5-related drugs. These can be dangerous and can interact unpredictably.

8) Blood pressure medicines

Because sildenafil can lower blood pressure modestly, the combination with other antihypertensives can increase the risk of dizziness.

Tell your pharmacist about all medicines and supplements you use, including:

• Prescription medicines
• Over-the-counter products
• Herbal supplements (e.g., products marketed for “male enhancement”)
• Recreational drugs

Safety Profile: Side Effects and When to Seek Help

Like all medicines, Assurans can cause side effects. Most are mild to moderate and resolve on their own. However, some situations require urgent medical attention.

Common side effects

• Headache
• Flushing
• Dizziness
• Indigestion or upset stomach
• Nasal congestion
• Visual changes (e.g., a bluish tinge or increased light sensitivity)

Less common but important

• Palpitations
• Low blood pressure symptoms (faintness, feeling weak)
• Prolonged erections (see below)

Seek emergency help immediately

Get urgent medical assistance if you experience:

• Chest pain, severe shortness of breath, or fainting
• Severe dizziness or collapse
• Sudden vision loss or severe eye pain
• Sudden hearing loss or ringing with reduced hearing
• Priapism: an erection lasting 4 hours or more (urgent—risk of tissue damage)

Important: If you have a medical emergency and need treatment for chest pain, tell staff that you’ve taken sildenafil. Because nitrates can be dangerous, clinicians need accurate timing information.

Practical Use Tips for Better Results

• Give yourself the right timing: take it about 30–60 minutes before sex (especially on first use).
• Consider meal size: heavy or fatty meals can delay onset—plan timing accordingly.
• Be mindful with alcohol: keep alcohol moderate to reduce dizziness and improve effectiveness.
• Start low if you’re sensitive: older age or low blood pressure tendencies may warrant lower starting doses.
• Relaxation helps: performance anxiety is common. Sildenafil supports blood flow but does not replace sexual stimulation.
• Avoid “stacking” doses: taking extra doses won’t reliably improve results and increases side effects risk.
• Check drug lists: confirm you’re not combining with nitrates, riociguat, or other high-risk interactions.

If Assurans doesn’t seem to work, it may be due to timing, food, alcohol, or interacting medicines. A pharmacist can help review your situation safely.

Alternative Options

There are several ways to address erectile dysfunction or pulmonary arterial hypertension, depending on your diagnosis and health profile.

For erectile dysfunction

• Other PDE5 inhibitors: such as tadalafil or vardenafil (choice depends on your schedule and interactions).
• Non-oral options: vacuum erection devices, penile injections, or other specialist therapies may be suitable for some people.
• Lifestyle measures: regular exercise, weight management, smoking cessation, and reducing alcohol can improve outcomes over time.
• Managing underlying causes: conditions like diabetes, high blood pressure, or high cholesterol can contribute to ED—addressing these can help.

For pulmonary arterial hypertension

• PAH treatments can include other medicine classes (e.g., endothelin receptor antagonists, prostacyclin pathway therapies, and combination regimens) depending on severity and specialist guidance.

Your healthcare professional can help choose the most appropriate option based on your condition and medication interactions.
