Overview: Sildenafil 25mg tablets
Erectile dysfunction affects many men worldwide, impacting quality of life and relationships. Sildenafil 25mg tablets provide a proven, accessible option to manage ED symptoms effectively. By relaxing blood vessels in the penis, Sildenafil improves blood flow, which is essential for achieving a firm erection [1][2].
Starting with a 25mg dose allows healthcare providers to assess tolerance and effectiveness, with options to adjust dosage if necessary. This flexibility helps balance efficacy with minimising potential side effects [3].
Active ingredient: Sildenafil 25mg tablets
The active ingredient in Sildenafil 25mg tablets is sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor. Sildenafil works by blocking the PDE5 enzyme, which normally breaks down cyclic guanosine monophosphate (cGMP)—a molecule that promotes relaxation of smooth muscle and blood vessel dilation in the penis [2][4].
By inhibiting PDE5, Sildenafil allows cGMP to accumulate, leading to improved blood flow and enabling an erection in response to sexual stimulation. This mechanism is the basis for Sildenafil’s effectiveness in treating erectile dysfunction.
The 25mg tablets contain a lower dose of sildenafil citrate, making them suitable for men who need a gentler start or experience side effects at higher doses [3].
What are sildenafil 25mg tablets used for?
Sildenafil 25mg tablets are primarily prescribed to treat erectile dysfunction (ED), a condition where men have difficulty achieving or maintaining an erection sufficient for sexual activity. ED can result from various causes including cardiovascular disease, diabetes, stress, or age-related changes [1].
In addition to ED, Sildenafil is sometimes used off-label for conditions such as pulmonary arterial hypertension, but the 25mg tablet strength is specifically targeted for ED treatment [2].
By improving blood flow to the penis during sexual arousal, Sildenafil helps restore sexual function and confidence, enhancing quality of life.
How do sildenafil 25mg tablets work?
Sildenafil belongs to the class of medications known as PDE5 inhibitors. Under normal circumstances, sexual stimulation leads to the release of nitric oxide in the penis, which activates an enzyme that produces cGMP. This molecule causes smooth muscle relaxation and vasodilation, allowing blood to fill the penile chambers and create an erection [2][4].
However, PDE5 breaks down cGMP, limiting the duration of an erection. Sildenafil blocks PDE5, preventing this breakdown and allowing cGMP to accumulate, sustaining the erection during sexual activity.
It’s important to note that Sildenafil does not cause an erection on its own; sexual arousal is still necessary for the medication to work. The sildenafil 25mg dose provides a mild but effective boost to this natural process, making it suitable for many men starting treatment [3].
How to take sildenafil 25mg tablets?
Sildenafil 25mg tablets should be taken as directed by your healthcare provider, usually around one hour before planned sexual activity.
Swallow the tablet whole with a glass of water.
For best results, take Sildenafil on an empty stomach, as food—especially high-fat meals—can slow down absorption and delay the onset of action.
Do not take more than one tablet in a 24-hour period. If you find the 25mg dose effective but experience side effects, consult your doctor about adjusting your dose.
Avoid grapefruit juice, as it can interfere with how the medication works [1][2].
Warnings and precautions: Sildenafil 25mg tablets
Before starting Sildenafil 25mg tablets, discuss your full medical history with your healthcare provider.
Do not take Sildenafil if you use nitrate medications for chest pain, as this combination can cause a dangerous drop in blood pressure.
The tablets are not suitable for those with severe heart or liver problems, recent history of stroke or heart attack, or certain rare inherited eye diseases.
Always inform your doctor if you have low blood pressure, bleeding disorders, or anatomical deformities of the penis
Sildenafil 25 mg tablets are only licensed for men and should not be used by women [1][2][3].
Side effects of sildenafil 25mg tablets
Most side effects of Sildenafil 25mg tablets are mild and temporary.
Common side effects include headache, flushing, indigestion, acid reflux, nasal congestion, dizziness, nausea, and visual disturbances (such as a blue tint to vision or blurred vision).
Less commonly, some may experience muscle aches, rash, or palpitations.
Rare but serious side effects include chest pain, prolonged or painful erections (priapism), sudden hearing or vision loss, and allergic reactions. If you experience any severe or persistent symptoms, seek medical attention immediately [4][2].
Drug interactions with sildenafil 25mg tablets
Sildenafil 25mg tablets, used to treat erectile dysfunction, may interact with various other medications. Such interactions can alter the effectiveness of sildenafil or increase the risk of side effects.
Do not use alongside nitrate medications (e.g., for angina) or medications called guanylate cyclase stimulators (such as riociguat), as this can cause a dangerous drop in blood pressure.
Use caution with alpha-blockers, antihypertensives, and certain antifungals or antibiotics.
Tell your doctor about all medicines and supplements you are taking, including over-the-counter remedies. Alcohol can worsen side effects, and grapefruit juice may increase the risk of adverse reactions [2], [3], [7], [8].

Note: A higher dose of sildenafil might be needed.
Other ED Medications:
Examples: Tadalafil, vardenafil
Effect: Combining these can increase the risk of severe side effects, such as a prolonged erection (priapism)
Note: Do not mix sildenafil with other erectile dysfunction treatments.
Grapefruit Juice:
Effect: Can raise blood levels of sildenafil, intensifying both its effects and side effects
