Femalegra (Sildenafil Citrate) – Patient Information (UK)

Femalegra is a brand of sildenafil citrate, a medicine best known for treating erectile dysfunction in men. In the UK, sildenafil is also used by some people to help improve certain aspects of sexual function, where clinically appropriate. This page explains what the medicine does, how it works, how to take it safely, and what to expect.

Always read the patient information leaflet (PIL) included with your pack and follow the advice of your healthcare professional if you are unsure. If your symptoms worsen or do not improve, seek medical advice.

Quick overview

• Active ingredient: Sildenafil citrate
• Common strength options: Vary by product (often 25 mg, 50 mg, 100 mg tablets in sildenafil products)
• How it helps: Supports blood flow to help improve sexual response
• When to take: Usually about 30–60 minutes before sexual activity
• Duration of effect: Often lasts several hours
• Important safety note: Never take sildenafil with nitrates or riociguat

What is Femalegra?

Femalegra contains sildenafil citrate. Sildenafil belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. PDE5 inhibitors work by helping to relax blood vessels and increase blood flow where it is needed during sexual stimulation.

While sildenafil is widely used for erectile function, some people may use it for other sexual function goals where appropriate. Your pharmacy or clinician can advise which use is most suitable for you.

How sildenafil works (mechanism of action)

Sexual stimulation triggers the release of nitric oxide (NO) in the body. NO increases levels of a substance called cyclic guanosine monophosphate (cGMP), which helps smooth muscle relaxation and increases blood flow.

Sildenafil works by blocking the PDE5 enzyme, which normally breaks down cGMP. By inhibiting PDE5:

• cGMP levels stay higher for longer
• blood vessels relax more effectively
• blood flow increases in relevant tissues
• sexual response may be improved when you are adequately stimulated

Important: Sildenafil does not automatically produce arousal. You still need sexual stimulation for best results.

Pharmacokinetics (how the body handles the medicine)

Pharmacokinetics describes what happens to a medicine in the body—absorption, distribution, metabolism, and elimination. While individual responses can vary, typical sildenafil behaviour includes:

• Absorption: Sildenafil is absorbed from the gut and reaches peak blood levels in about 30–120 minutes (often around 1 hour).
• Onset of effect: Many people feel an effect within 30–60 minutes.
• Duration: The effect can last for several hours. Some benefit may extend up to 4 hours or longer depending on the person and dose.
• Metabolism: Mainly broken down by the liver enzyme system (notably CYP3A4).
• Elimination: Mostly cleared as metabolites, primarily through the faeces and to a lesser extent in urine.

Liver or kidney conditions, age, and interacting medicines can change how quickly sildenafil is processed.

What is Femalegra used for? (indications)

Sildenafil is used for:

• Erectile dysfunction (in men) and related sexual function concerns
• In some circumstances, sildenafil may be used to address certain sexual dysfunction symptoms where clinically considered appropriate.

If you are using Femalegra for a specific purpose, ensure that it matches your condition and that you understand the expected benefits and limitations. Sexual function can be influenced by many factors (hormonal balance, relationship factors, stress, medications, pain, and cardiovascular health).

Typical dose and how to take it

Dosing can vary depending on age, medical history, kidney/liver function, and interacting medicines. Use the dose described on your pack or as advised by your clinician/pharmacist.

Typical adult dosing (general information)

• Common starting dose: Often 50 mg (may be lower for some people)
• Adjustments: Depending on how well it works and side effects, doses may be adjusted
• Maximum frequency: Do not take more than once per day

Do not exceed the recommended dose. Taking more will not necessarily improve results and may increase side effects.

How to take

• Take the tablet with water.
• Try to take it consistently before planned sexual activity.
• If it’s your first time, many people start on a lower dose to check tolerance.

Timing: when to take Femalegra

Timing can make a difference. Many people find it works best when taken shortly before sexual activity.

• Typical timing: about 30–60 minutes before sex
• Faster or slower onset: Can vary with body chemistry and meal content
• Allow enough time: If taken too close to sex or after a heavy meal, effect may be delayed

For best results, allow a window of time to see how your body responds during your first few attempts.

Food interactions (what you eat matters)

Food can affect how quickly sildenafil is absorbed.

• Heavy, high-fat meals: May delay absorption and make the medicine take longer to work.
• Light meals: Usually have less effect on onset time.

Tip: If you want a more predictable onset, consider taking it after a lighter meal or when your stomach is not overly full.

Alcohol interactions

Alcohol can affect sexual performance and cardiovascular stability. Small amounts may be tolerated by some people, but alcohol can also increase side effects such as dizziness and headache.

• Avoid heavy drinking: It may reduce effectiveness and increase risks.
• Be cautious if you feel dizzy: Sildenafil can lower blood pressure in some people.
• Driving/operating machinery: If you feel unwell, do not drive.

If you have heart disease or take medicines that affect blood pressure, discuss safe alcohol limits with a clinician.

Medicine interactions (important safety information)

Sildenafil can interact with other medicines, particularly those that affect blood pressure or liver metabolism. Some combinations are dangerous and must be avoided.

Do NOT take sildenafil with the following

• Nitrates (for example, glyceryl trinitrate/GTN or isosorbide): risk of a dangerous drop in blood pressure.
• Riociguat: risk of severe hypotension.

Be careful with the following (may require dose adjustments or monitoring)

• Alpha-blockers used for prostate symptoms or blood pressure (e.g., tamsulosin, doxazosin): can add to blood pressure lowering.
• Strong CYP3A4 inhibitors (may increase sildenafil levels), such as:
  • some antifungals (e.g., ketoconazole, itraconazole)
  • some antivirals used in HIV treatment
  • clarithromycin
  This can raise side effect risk.
• Medicines that strongly affect blood pressure (e.g., antihypertensives): may increase dizziness or light-headedness.

Commonly asked interaction topics

• Antacids: Most do not cause major issues, but severe reflux medicines can vary—check your pharmacy advice.
• Other erectile dysfunction medicines: Do not combine with sildenafil or similar PDE5 inhibitors.

If you are taking any regular medicines, bring a list to your pharmacist or clinician for interaction checks. This includes herbal products and recreational substances.

Safety profile and side effects

Like all medicines, Femalegra (sildenafil citrate) can cause side effects. Not everyone gets them. Side effects are often dose-related.

Common side effects

• Headache
• Flushing (warmth/redness of the face)
• Dizziness
• Indigestion or nausea
• Stuffy nose
• Visual changes (sometimes a bluish tint or increased light sensitivity)

Less common but important side effects

• Low blood pressure or feeling faint
• Palpitations (awareness of heartbeat)
• Rash

Seek urgent medical help if

• You have chest pain, severe shortness of breath, or fainting (especially during or after sexual activity).
• You experience an erection lasting more than 4 hours (priapism). This is an emergency.
• You have sudden vision loss or sudden hearing problems (rare, but can be serious).
• You develop severe allergic symptoms such as swelling of the face/lips, difficulty breathing, or widespread rash.

Who should be extra cautious?

Extra caution is advised if you have:

• significant heart disease or uncontrolled blood pressure
• history of stroke or certain cardiac conditions
• severe liver disease
• severe kidney impairment
• retinitis pigmentosa (a rare inherited eye condition)
• low blood pressure or tendency to faint

Practical use tips for best results

• Start low if you’re new: Many people benefit from a cautious first attempt to assess side effects and effectiveness.
• Give it a fair try: Sildenafil may work better on subsequent attempts once timing and dose are optimised.
• Allow time for arousal: Sildenafil supports response to stimulation; it does not replace desire.
• Manage stress and anxiety: Psychological factors can strongly influence sexual function.
• Stay hydrated: Dehydration can worsen headaches and dizziness.
• Avoid grapefruit: Grapefruit products may raise sildenafil levels in some people.
• Consider lubrication: If dryness or discomfort is present, water-based lubricants may help.

Alternative options

Depending on the underlying cause of symptoms, alternative approaches may be considered alongside or instead of sildenafil.

Other PDE5 inhibitors

• Tadalafil (different onset and duration characteristics)
• Vardenafil
• Avanafil

Non-medicine options

• Address contributing factors (stress, relationship dynamics, anxiety, pain, sleep)
• Review medications that may affect sexual function (some antidepressants and blood pressure medicines, for example)
• Pelvic floor physiotherapy may help some people
• Talking therapies or sex therapy can be beneficial, especially when anxiety is present

Your pharmacist can advise on general alternatives and help you choose an appropriate option if sildenafil doesn’t suit you.
