SILDENAFIL 25 MG TABLETS – Uses, Safety Information & FAQs
Product Overview
Sildenafil 25 mg Tablets contain sildenafil, a phosphodiesterase type-5 (PDE5) inhibitor used for the treatment of erectile dysfunction (ED). Sildenafil works by increasing blood flow to the penis when sexual stimulation occurs. The 25 mg strength is an established tablet strength and may be prescribed in certain patients depending on clinical circumstances.
Sildenafil should be used only according to the advice of a qualified healthcare professional. The appropriate dose can vary according to age, medical conditions, other medicines, and individual response.
Key Information About Sildenafil 25 mg
Active ingredient: Sildenafil
Strength: 25 mg
Drug class: PDE5 inhibitor
Primary medical use: Erectile dysfunction
Dosage form: Oral tablet
Use: As directed by a healthcare professional
How Sildenafil Works
Sildenafil inhibits the PDE5 enzyme, helping support the nitric oxide/cGMP pathway involved in penile blood-flow regulation. It does not produce an erection by itself; sexual stimulation is still required for the medicine to work.
Sildenafil 25 mg Dosage Information
The appropriate sildenafil dose should be determined by a healthcare professional. Official prescribing information lists 25 mg, 50 mg, and 100 mg tablet strengths. For some patients, including certain older adults or people with severe renal or hepatic impairment, 25 mg may be considered as a starting dose.
Sildenafil should not be taken more frequently than recommended. The prescribing information specifies a maximum recommended dosing frequency of once daily.
Important Drug Interactions
Sildenafil must not be taken with nitrate medicines or nitric-oxide donors because the combination can cause a potentially dangerous drop in blood pressure. It is also contraindicated with guanylate cyclase stimulators such as riociguat.
Patients taking alpha-blockers or certain medicines that affect CYP3A4 metabolism may require special dosing or medical supervision.
Possible Side Effects
Common or reported adverse effects may include:
Headache
Flushing
Indigestion
Nasal congestion
Dizziness
Visual disturbances
Seek urgent medical attention for an erection lasting more than four hours. Sudden loss of vision or hearing also requires prompt medical evaluation.
Cardiovascular Safety
Sexual activity can carry cardiovascular risks for some individuals. Sildenafil may not be appropriate for people for whom sexual activity is medically inadvisable because of their cardiovascular condition. A healthcare professional should assess cardiovascular suitability before treatment.
