Grapefruit juice can inhibit CYP3A4 enzymes and modestly increase sildenafil levels, potentially enhancing side effects. Occasional consumption is unlikely to cause problems, but regular large amounts should be discussed with a clinician.
Both drugs are PDE5 inhibitors, but sildenafil has a shorter duration of action (≈4 hours) compared with tadalafil’s up to 36 hours. Choice of therapy depends on individual response, lifestyle preferences, and physician guidance.
Moderate alcohol intake does not usually interfere with effectiveness, but excessive drinking may reduce the ability to achieve an erection and increase the risk of hypotension. Caution is advised.

Yes, the active ingredient sildenafil is available as a generic medication in the UK. Generic formulations contain the same amount of active drug and are regulated to meet the same quality standards.
Fildena is a brand-name medication that contains the active ingredient sildenafil. It is formulated as a pill and is marketed in a 100 mg strength. Sildenafil belongs to the therapeutic class of Erectile Dysfunction (ED) treatments and works as a phosphodiesterase type 5 (PDE5) inhibitor. In the United Kingdom, Fildena is a prescription-only product and is regulated by the Medicines and Healthcare products Regulatory Agency (MHRA). The specific manufacturer of Fildena is not disclosed in publicly available sources, but the active ingredient is identical to the generic drug sildenafil, which is widely available under various brand names.
Sildenafil inhibits the enzyme phosphodiesterase type 5 (PDE5). In men, sexual stimulation leads to the release of nitric oxide in the corpus cavernosum of the penis. Nitric oxide activates guanylate cyclase, increasing levels of cyclic guanosine monophosphate (cGMP). Elevated cGMP causes smooth-muscle relaxation and vasodilation, allowing blood to fill the erectile tissue. By blocking PDE5, sildenafil prolongs the action of cGMP, enhancing and sustaining the erection in response to sexual stimulation. The drug does not cause an erection without sexual arousal.
Fildena is approved in the UK for the treatment of erectile dysfunction in adult males. It is indicated when a man is unable to achieve or maintain an erection sufficient for satisfactory sexual performance. Sildenafil is also approved in other jurisdictions for pulmonary arterial hypertension (under the brand name Revatio); however, Fildena is labeled specifically for erectile dysfunction.
