Sildenafil citrate, commonly known by the brand name, is a prescription-only medicine used to treat erectile dysfunction (ED) in adult men. It works by improving blood flow to the penis, helping to achieve and maintain an erection during sexual activity.
Sildenafil is available in 25mg, 50mg, and 100mg strengths.
Sildenafil has been shown to be effective in up to 80% of men with ED, with effects typically noticeable within 30 to 60 minutes, and lasting for up to 4–5 hours.

On 14 March 2023, the UK Medicines regulator approved an application to reclassify the erectile dysfunction medication Cialis. When marketed asCialis Together(tadalafil 10mg), it will be a ‘P’ (pharmacy) medication, and so available ‘over the counter’ in pharmacies – see. This follows the 2018, ‘P’ classification of (sildenafil 50mg) which has been available OTC, without a prescription, since then.
This decision is good news for men’s health …. Erectile dysfunction can be a debilitating condition, so it’s important men feel they have fast access to quality and legitimate care
Dr Laura Squire, MHRA’s Chief Officer for Healthcare, Quality and Access
Unfortunately, there is a strong black market in the UK for ED medicines, which are often unlicensed or counterfeit. UK Border Force and the MHRA seize millions of pounds of these fake products from criminals annually. This new classification of tadalafil 10mg will enable men who suffer from ED to obtain it safely from a local pharmacy.
Sanofi, the drug manufacturer, is expected to launch Cialis Together later in 2023. Cialis Together will be available to purchase in pharmacies without a prescription by men over 18 with erectile dysfunction. Cialis Together tablets will contain 10mg tadalafil and the maximum pack size will be 8 tablets. Other doses and pack sizes of Cialis and tadalafil will still be available on prescription through doctors and specially trained pharmacists. Before purchase in a pharmacy there must be an assessment with a pharmacist, who will check that Cialis Together is appropriate and safe, or whether consultation with a GP is necessary.
Men suffering with ED will have another treatment option with the convenience of purchasing it in their local pharmacy, including pharmacies found inside supermarkets (eg. Tesco, Asda, Sainsbury’s). The pharmacist will ask some health questions, may check blood pressure, and will advise on treatment with Cialis Together or Viagra Connect, or the need to consult a GP. Pharmacies usually have a private room for such discussions.
Cialis Together is a 10mg tadalafil product for use at least 30 minutes prior to anticipated sexual activity. Its effects can last. It is not recommended for daily use. The maximum recommended dose of Cialis Together will be one tablet in 24 hours. Prescription Cialis and tadalafil will still be available at different doses.
Dr Fox welcomes the wider access to ED medication for men that Cialis Together classified as a ‘P’ OTC medication will provide. We at Dr Fox are aware of the difficulties men have in discussing ED with their GPs and in accessing ED medication. We know that Cialis is effective and safe for most men and this change provides another option for obtaining ED treatment. Pharmacists are health professionals who are able to give ED advice but they will also know when to refer men who would benefit from a doctor’s assessment. ‘P’ medicines can also be supplied on prescription, and we will offer Cialis Together, when available, alongside our other competitively priced ED products.

If you experience any of these side effects, seek medical attention immediately. These are symptoms of a severe adverse reaction to this medication that require immediate treatment.
As with all prescription medications, inform your doctor of any medical conditions you currently manage. Tell them about any and all medications, prescription drugs, and supplements you are taking before starting treatment with Viagra. Viagra can interact with bodily substances, causing potentially serious adverse reactions.
Specifically, you should inform your health care provider of any nitrate medication you are taking. Remember to mention any herbal products you use, especially St. John’s wort.
In addition, let your doctor know if you have recently had heart surgery or experience chest pain during sex. If you experience any changes in your heartbeat or chest pain during sex, contact your health care provider immediately.

It increases blood flow to the penis to improve sexual desire and function.
Viagra works by relaxing the muscles in the walls of blood vessels, allowing for increased blood flow. This can improve erectile function.
It does not cure ED, but it can help reduce symptoms like headache, fever, indigestion, and fatigue. Viagra is not recommended for women who are pregnant, planning to become pregnant, or breastfeeding.
Viagra may also interact with certain other medications, including blood pressure medications, antibiotics, and diuretics. Taking Viagra with these interactions may increase the risk of priapism (a serious health problem that can be a choking hazard).
To reduce the risk and severity of side effects, Viagra should be taken exactly as it was last month. Most men taking Viagra have taken it as directed by their healthcare provider.
If you are taking Viagra inconsistently, double down on a time. Take it for as long as you can, but only when you need it least-one dose per day.
Do not take Viagra more than once a day. If you take it too early, you may experience side effects such as headache, flushing, heartburn, and indigestion.
Viagra is used in the treatment of erectile dysfunction and pulmonary arterial hypertension. Sildenafil citrate has an inhibitory effect on phosphodiesterase type 5 (PDE5) and a nitric oxide (NO) pathway. The inhibition of PDE5 and NO by sildenafil citrate results in increased cyclic guanosine monophosphate (cGMP) concentration in the corpus cavernosum and increases cGMP accumulation in the smooth muscle of the penis. The increased cGMP concentration in the corpus cavernosum may help to sustain an erection and facilitate erection for a prolonged duration. Sildenafil citrate inhibits the activity of phosphodiesterase type 5 (PDE5) in the smooth muscle cells of the corpus cavernosum, which facilitates the breakdown of cGMP. Sildenafil citrate has a short half-life of about 5 hours and is not metabolized by the liver or cytochrome P450 enzymes. Sildenafil citrate may cause adverse effects in the following situations:
The safety of sildenafil citrate is unknown. The safety of sildenafil citrate is also not well established in children and adolescents. Therefore, sildenafil citrate is not recommended in patients with a history of hypertension or angina or other serious cardiovascular disease.
The use of sildenafil citrate in patients with hypertension and angina has been shown to be safe and effective in clinical trials and in randomized clinical trials in the treatment of patients with hypertension and angina.
The contraindications of sildenafil citrate include a hypersensitivity to sildenafil citrate, severe renal impairment, severe hepatic dysfunction, severe cardiac insufficiency, severe renal impairment, severe cardiac insufficiency, a history of an allergic reaction to sildenafil citrate, a history of bleeding disorders, or an increased serum calcium concentration in the blood.
The dose of sildenafil citrate is 50 mg taken 3 times a day for 3 days.
