Fildena 120: Sildenafil 120mg Uses, Safety, Side Effects & Information
Fildena 120 is a product name associated with a high-strength sildenafil formulation. Sildenafil belongs to a class of medicines known as phosphodiesterase type 5 (PDE5) inhibitors and is used in approved medicines for the treatment of erectile dysfunction (ED). Manufacturer information identifies Fildena products as sildenafil-based medicines used for erectile dysfunction.
The exact formulation, strength, manufacturer, and regulatory status of products sold under the Fildena name can vary by market. Always verify the active ingredient and strength on the original packaging and consult a qualified healthcare professional before using sildenafil.
What Is Fildena 120?
Fildena 120 is marketed as a tablet containing 120 mg of sildenafil. Sildenafil works by supporting increased blood flow to penile tissue when sexual stimulation occurs.
It is important to distinguish the marketed product strength from standard prescribing recommendations. FDA-approved Viagra labeling for erectile dysfunction lists 25 mg, 50 mg, and 100 mg tablets, with 100 mg as the maximum recommended dose and once-daily maximum frequency. A 120 mg sildenafil product is therefore above that labeled maximum for ED.
For this reason, Fildena 120 should not be treated as a routine erectile-dysfunction dose or used simply to obtain a stronger effect.
What Is Fildena 120 Used For?
Sildenafil is primarily associated with the treatment of erectile dysfunction in adult men.
Erectile dysfunction refers to difficulty achieving or maintaining an erection sufficient for satisfactory sexual activity. It can have many causes, including cardiovascular disease, diabetes, high blood pressure, hormonal conditions, neurological disorders, certain medicines, anxiety, stress, and other health factors.
Sildenafil supports the physical mechanism involved in an erection. It does not directly increase sexual desire and does not automatically produce an erection. Sexual stimulation is necessary for its intended erectile effect.
Persistent ED may sometimes be associated with an underlying health condition, so recurring symptoms should be evaluated by a healthcare professional.
How Does Sildenafil Work?
During sexual stimulation, nitric oxide is released in penile tissue. This contributes to the formation of cyclic guanosine monophosphate (cGMP), which helps relax smooth muscle and increase blood flow into erectile tissue.
The PDE5 enzyme breaks down cGMP. Sildenafil inhibits PDE5, allowing cGMP activity to remain available for longer. This supports increased blood flow and can help facilitate an erection when sexual stimulation is present.
Sildenafil is therefore not an aphrodisiac. It does not create sexual arousal independently.
Fildena 120 Dosage Information
The appropriate sildenafil dose depends on an individual’s health, other medicines, age, kidney and liver function, cardiovascular status, and response to treatment.
For FDA-approved sildenafil treatment of ED, the usual recommended dose is 50 mg taken as needed, with adjustment based on effectiveness and tolerability to 25 mg or 100 mg. The maximum recommended dosing frequency is once per day.
Because 120 mg exceeds this labeled maximum, it should not be considered a standard ED dose.
Do not increase the sildenafil dose independently or combine multiple sildenafil-containing products. Taking a higher amount can increase drug exposure and the likelihood of adverse effects.
How to Use Sildenafil Safely
If a healthcare professional has prescribed sildenafil, follow the exact instructions provided with the prescription and product information.
Important considerations include:
- Use only the prescribed amount.
- Do not take additional sildenafil if the expected effect does not occur.
- Do not combine sildenafil with other PDE5 inhibitors unless specifically directed.
- Tell your healthcare professional about all prescription and non-prescription medicines you use.
- Discuss alcohol consumption with your healthcare professional.
- Keep the medicine away from children and people for whom it was not prescribed.
Standard sildenafil labeling allows administration approximately 30 minutes to 4 hours before sexual activity, with approximately one hour being the typical timing described for most patients.
Possible Side Effects of Fildena 120
Sildenafil can cause side effects. Commonly reported reactions include:
- Headache
- Facial flushing
- Indigestion
- Nasal congestion
- Dizziness
- Visual disturbances
- Changes in color perception
The risk of adverse effects may increase with higher exposure to sildenafil.
Seek immediate medical attention for serious symptoms such as chest pain, fainting, severe allergic reactions, sudden vision loss, sudden hearing loss, or an erection lasting longer than four hours.
A prolonged erection, known as priapism, is a medical emergency and requires prompt treatment. FDA labeling specifically advises emergency treatment when an erection lasts more than four hours.
Fildena 120 Drug Interactions
Sildenafil can interact with several medicines.
The most important interaction is with nitrate medicines, including organic nitrates and nitrites. Sildenafil can potentiate the blood-pressure-lowering effects of nitrates, and this combination is contraindicated.
Sildenafil can also interact with:
- Alpha-blockers
- Certain blood-pressure medicines
- Strong CYP3A4 inhibitors
- Certain HIV medicines
- Some antifungal medicines
- Certain antibiotics
- Other PDE5 inhibitors
Patients taking ritonavir or certain other interacting medicines may require substantially lower sildenafil exposure according to prescribing guidance.
Always provide a complete list of prescription medicines, over-the-counter products, vitamins, and supplements to your healthcare professional.
Fildena 120 and Alcohol
Alcohol can contribute to dizziness and low blood pressure and may independently interfere with erectile function. Combining substantial alcohol consumption with sildenafil may therefore increase the likelihood of unwanted effects.
Discuss alcohol use with your healthcare professional and avoid excessive consumption while using sildenafil.
Who Should Exercise Caution?
Medical assessment is particularly important for people with:
- Cardiovascular disease
- Low blood pressure
- Uncontrolled hypertension
- Kidney problems
- Liver problems
- A history of stroke or heart attack
- Certain eye conditions
- A history of prolonged erections
Sildenafil should not be used when sexual activity itself is medically inadvisable because of cardiovascular status.
People taking nitrate medicines or guanylate cyclase stimulators such as riociguat should not use sildenafil because of potentially significant blood-pressure effects.
Frequently Asked Questions
What is Fildena 120?
Fildena 120 is a product name associated with a high-strength sildenafil formulation. Fildena products are marketed as sildenafil-based medicines for erectile dysfunction.
Is 120 mg sildenafil a standard ED dose?
No. FDA-approved sildenafil labeling for erectile dysfunction lists 25 mg, 50 mg, and 100 mg strengths, with 100 mg as the maximum recommended dose. A 120 mg product therefore exceeds that labeled maximum.
Does Fildena 120 increase sexual desire?
No. Sildenafil does not directly increase libido. It supports the physical erectile response when sexual stimulation occurs.
Does sildenafil cause an automatic erection?
No. Sexual stimulation is required for sildenafil to facilitate an erection.
Can sildenafil be taken with nitrates?
No. Sildenafil must not be combined with nitrate medicines because this can cause a potentially dangerous decrease in blood pressure.
What should I do if an erection lasts more than four hours?
Seek immediate emergency medical attention. A prolonged erection can cause permanent tissue damage if treatment is delayed.
Final Information
Fildena 120 is associated with a high-strength sildenafil formulation marketed for erectile dysfunction. Sildenafil is a PDE5 inhibitor that supports blood flow to penile tissue during sexual stimulation.
However, standard FDA-approved sildenafil prescribing information recommends a maximum of 100 mg for as-needed treatment of erectile dysfunction, making 120 mg higher than the labeled maximum.
For responsible use, verify the product’s active ingredient and strength, review potential drug interactions with a qualified healthcare professional, and follow the applicable prescribing information. Do not increase the sildenafil dose independently or combine it with other ED medicines.
