Panorama of the topmost levelic and main points

Products labelled as "extra dose" or similar commonly contain sildenafil at strengths above the conventionally licensed single dose of 100 mg. Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction in adult men by supporting the physiological erection response when sexual stimulation occurs. It does not itself cause arousal or an erection without sexual stimulation.

Fast data:

  • Sildenafil is the main active ingredient
  • Indication: treatment of erectile dysfunction in adult men
  • Licensed single-tablet maximum in routine UK practice: 100 mg

Products offering 120 mg, 150 mg or 200 mg per tablet exceed routine licensing in the UK and carry higher risk. For practical instructions see steps on how to take medicine and time properly, and for safety measures and standard precautions to take into accountplease check. the safety resources remember the safety risk warnings.

Strengths available and unlicensed variants

Licensed sildenafil tablets in UK practice are usually 25 mg, 50 mg and 100 mg. Some suppliers may market tablets labelled as higher strengths (for example 120 mg, 130 mg, 150 mg or 200 mg). These are not standard licensed options in routine primary care.

Clinical adjustments commonly involve choosing a different licensed strength or advising tablet splitting rather than using single-tablet strengths above 100 mg. If a seller offers an unusual strength online, verify its origin and consult a prescriber check prior to use.

See counsel on legal and purchasing matters for rules on buying medicines in the UK.

Explaining how sildenafil works

Sildenafil inhibits PDE5, an enzyme that breaks down cyclic GMP in smooth muscle cells. By reducing PDE5 activity, sildenafil helps relax blood vessel walls in the penis, increasing blood flow during sexual stimulation and enabling erection formation and maintenance. It will not produce an erection in the absence of sexual arousal.

Timing and dose influence onset and duration; refer to timing of dosing below.

Taking sildenafil: administration timing and dosage

Always follow the instructions from your prescriber or pharmacist. Do not take more than one sildenafil dose in any 24 hour period.

  • Take the tablets with a glass of water. A fatty meal may delay absorption and slow the onset of effect.
  • Typical onset of action is 30 to 60 minutes; some individuals may need up to 4 hours to notice an effect.
  • If you miss a planned dose, take it when you remember provided you will not exceed the one-dose-per-day limit.

Usual UK starting dose is 50 mg about one hour before sex; this can be decreased to 25 mg or increased to 100 mg based on efficacy and tolerability. Doses above 100 mg are not part of routine UK prescribing and should only be considered under specialist supervision. If you are being advised a higher dose, discuss the rationale and metric monitoring plan with a clinician. Regard the safety checks documentation. medical grounds for not using this treatment and health and safety cautions.

Efficient archived data is kept in long term storage. and handling

Store sildenafil at around 25 degrees C when possible. Short excursions between 15 and 30 degrees C are generally acceptable. Keep tablets dry and away from direct heat or strong light. Avoid storing medicines in bathrooms where humidity can be high.

  • Store this product where children and pets cannot reach.
  • Do not use tablets that are damaged, discolored or out of date.

Conditions where use is not advised and user safety hazard alerts

Avoid sildenafil if any of these apply:

  • Known hypersensitivity to sildenafil or any tablet ingredient
  • Current use of nitrate medications (for example glyceryl trinitrate, isosorbide mononitrate) or sodium nitroprusside
  • Use of recreational alkyl nitrites ("poppers")
  • Concurrent use of another PDE5 inhibitor (for example tadalafil, vardenafil, avanafil) or another product containing sildenafil
  • Your clinician has advised against sexual activity because of a cardiovascular condition

Discuss with a prescriber before using sildenafil if you have:

  • A recent heart attack, stroke, uncontrolled angina or other unstable cardiac disease
  • Serious liver disease or significant kidney impairment
  • Blood disorders that predispose to priapism (for example sickle cell disease, multiple myeloma, leukemia)
  • Penile anatomical problems such as Peyronie disease
  • A history of sudden vision or hearing loss or hereditary retinal disorders such as retinitis pigmentosa

Additional cautions:

  • Loss of balance sensation, lightheadedness or visual changes can occur. Do not drive or use heavy equipment until you understand how the drug affects you.
  • An erection lasting longer than four hours is a medical emergency; seek immediate care to avoid permanent injury.
  • Sildenafil does not protect against sexually transmitted infections; use barrier contraception where appropriate.
  • Not licensed for patients under 18 years. Older adults may require dose adjustment.

Important dialogues among medications

Some frequent people relating to one anothers boost coordination. can be serious. Key examples:

  • Nitrates or nitric oxide donors: combining these with sildenafil can cause severedevelopment potentially life threatening hypotension.
  • Alpha blockers and many antihypertensives: risk of symptomatic low blood pressure when used together.
  • Strong CYP3A4 inhibitors (for example ritonavir, ketoconazole, itraconazole, clarithromycin): may increase sildenafil concentrations and adverse impact on health; a dose reduction or the other possibility may be required.
  • CYP3A4 inducers (for example rifampicin, efavirenz): may reduce sildenafil efficacy.
  • Central nervous system depressants (opioids, benzodiazepines): concurrent use may increase drowsiness or dizziness.

This list does not include everything. Always consult a pharmacist or prescriber before combining medicines or starting new supplements. Verify the file dosing reminders page additional details can be found here. administration timing with respect to dosing.

Long term effects to monitor and when to seek help

Typical deleterious effects, usually mild and transient:

  • Dull head pain
  • Facial redness and warmth
  • Digestive discomfort and dyspepsia
  • Nose that runs and gets blocked
  • Dizzy spells
  • Temporary visual disturbances such as altered color perception or increased light sensitivity

Visit the emergency room urgently for a possible concussion:

  • Signs of anaphylaxis: swelling of face, lips, throat or difficulty breathing
  • Chest pain, fainting or irregular heartbeat
  • Sudden monocular or binocular vision loss. or sudden hearing loss
  • An erection that is painful and lasts more than four hours (priapism)

If you experience any concerning adverse effect, tell your prescriber or pharmacist so they can advise whether you should stop or switch treatment.

Other therapeutic options and akin drugs

Several other licensed treatments for erectile dysfunction are available. Choice depends on personal response, side effect profile, duration of action and cost.

  • Sildenafil in licensed doses (25 mg, 50 mg, 100 mg). The 50 mg product branded as Viagra Connect can be supplied by a pharmacist after assessment; other strengths normally require a prescription.
  • Tadalafil: longer duration of action (up to 36 hours) and also available as a low-dose daily tablet (2.5 mg or 5 mg).
  • Vardenafil: similar efficacy to sildenafil, with some differences in onset timing paired with the back and forth of communication profile.
  • Avanafil: often has a faster onset for some users.
  • Non-oral options: alprostadil injections, intraurethral suppositories or topical agents for patients who cannot tolerate PDE5 inhibitors or do not respond to them.

Short comparison: tadalafil offers extended coverage, avanafil may act faster, while sildenafil and vardenafil share broadly similar effectiveness. Discuss with your clinician which option suits you best. See rate card differences in typical British price quotes.
