ABOUT THE MEDICATION

WHAT IS SILDENAFIL?

You may know it as the brand name ‘Viagra’, but the active ingredient is sildenafil which works in the same way to quickly improve your ability to get and maintain an erection. Sildenafil is just as effective as the branded version and it is MHRA approved to treat ED.

It doesn’t matter if you experience erectile dysfunction in your twenties or when you are over 40, it’s hard work made easy.

Progress Over Time

What to expect
with Sildenafil

  • Getting started

    Sildenafil will help you get and maintain an erection, but you will need to be sexually aroused. To help, you and your partner should engage in some foreplay to give the tablet time to work and to help you become sexually stimulated. It’s important to relax.

  • First few doses

    Sildenafil may not always work the first time you try to use it. For most men the tablets are more effective after the second dose. If you are unsuccessful, wait 24 hours and try again. Remember, you can’t take more than 1 tablet a day.

  • One tablet a day

    Do not take more than one tablet a day, even if you feel the drug is not working for you. If you feel the strength you are taking is too weak, then you should talk to your prescriber, who will recommend a higher dose for you.

  • Heart health

    Sexual activity can put further strain on the heart, so it is important to check with your doctor first if you get very breathless or feel any chest pain when you partake in light to moderate physical activity, such as climbing the stairs or taking a brisk walk.

Drug Interactions

Sildenafil interactions

  • Nitrates & poppers

    DO NOT take Sildenafil if you are already taking medicines for chest pain (‘angina’) or heart failure, such as nitrates (e.g. glyceryl trinitrate, isosorbide mononitrate, isosorbide dinitrate) or nitric acid donors (e.g. amyl nitrate or “poppers”, nicorandil, sodium nitroprusside). Sildenafil can cause a substantial drop in blood pressure when taken in combination with these medicines.

  • Pulmonary hypertension & HIV medicines

    DO NOT take Sildenafil if you are already taking medicines for arterial pulmonary hypertension (high blood pressure in the lungs) or chronic thromboembolic pulmonary hypertension (high blood pressure in the lungs due to blood clots), such as riociguat (or other drugs that belong the same group called guanylate cyclase stimulators), or a medicine called ritonavir for HIV infection.

  • Taking other medications with Sildenafil

    Other medicines may affect the way Sildenafil works. Check with us or your GP first if you are already taking any of the following medicines: alpha-blockers (e.g. alfuzosin, doxazosin or tamsulosin) to treat urinary problems due to an enlarged prostate (benign prostatic hyperplasia) or high blood pressure; protease inhibitors used to treat HIV infection; cimetidine used to treat heartburn; itraconazole or ketoconazole used to treat fungal infections; erythromycin, an antibiotic, used to treat bacterial infections.

WARNINGS

Sildenafil contraindications

    You are already taking medication for erectile dysfunction, which include any topical creams or ointments; you have previously had an allergic reaction to it; you have been advised by your doctor to avoid sexual activity.

  • HEART PROBLEMS OR BLOOD PRESSURE

    You have recently been diagnosed with heart problems, have had a heart attack or a stroke; you have low blood pressure or high blood pressure that is not well controlled.

  • EYE DISEASE OR DEFORMITY OF THE PENIS

    You suffer from certain inherited eye diseases such as retinitis pigmentosa or optic neuropathy; you have any disease or deformity of the penis (e.g. Peyronie’s Disease).

  • NOT FOR WOMEN OR ANYONE UNDER 18

    DO NOT take Sildenafil if you are a woman or you are under 18 years of age.

  • WHO CAN TAKE SILDENAFIL?

    Sildenafil is not suitable for everyone. You should check with your doctor first, before using Sildenafil if: you have a problem with the valves in your heart (valvular heart disease); you have a condition that causes the heart muscle to become inflamed (cardiomyopathy); you have had any surgery to correct or improve blood flow to your heart; you have previously had high blood pressure that is now under control; you have ever had a prolonged erection (priapism) that lasted more than 4 hours or any health condition that could cause priapism, such as sickle cell anaemia (abnormal red blood cells), leukaemia (cancer of the blood) or multiple myeloma (cancer of the bone marrow); you have a stomach ulcer or a bleeding disorder (haemophilia); you have been diagnosed with serious liver or kidney problems.

Lifestyle

What else can I do to help my ED?

You can make lifestyle changes to improve your ability to get and maintain an erection.

  1. 01

    Alcohol and Sildenafil

    Drinking alcohol with Sildenafil may reduce the effectiveness of the drug and could make getting an erection more difficult. It is therefore best to avoid alcohol if you intend to use Sildenafil that day.

  2. 02

    Driving and Using Machines

    Sildenafil has been reported to cause dizziness and can affect your vision, so it is important not to drive or use machinery if you experience these side effects.

  3. 03

    Lifestyle Changes

    Exercising regularly. Reducing your stress levels. Stop smoking. Avoid drinking excessive alcohol. Improve your mental health (particularly if you are anxious or depressed).

  4. 04

    Further Questions

Ongoing Care

Your 6 month check up

It is important for you to have a check up with your GP within 6 months of using Sildenafil, even if you feel healthy and well.

This is because erectile dysfunction could be an early warning sign of other underlying health issues, such as heart and blood pressure problems, diabetes, high blood pressure or high cholesterol.
