1. Why am I using Sildenafil Lupin?

This product contains the active ingredient sildenafil citrate. Sildenafil belongs to a group of medicines called phosphodiesterase type 5 inhibitors.

Sildenafil is used to treat erectile dysfunction, more commonly known as impotence, in men. This is when a man cannot get, or keep, a hard-erect penis suitable for sexual activity.

It works by relaxing the blood vessels in your penis when you are sexually excited. This allows blood to flow into your penis, allowing you to get an erection in the natural way.

Sildenafil Lupin will work only if you are sexually excited.

Sildenafil Lupin will not increase your sex drive.

Sildenafil Lupin is not for use in women.

This medicine is available only with a doctor’s prescription.

2. What should I know before I use Sildenafil Lupin?


Do not use Sildenafil Lupin if:

  • you are allergic to sildenafil, or any of the ingredients listed at the end of this leaflet. Always check the ingredients to make sure you can use this medicine.
  • you are being treated for angina (chest pain) or other heart conditions with medicines called nitrates. Nitrate medicines include glyceryl trinitrate (also called nitroglycerin). It may lead to a severe drop in your blood pressure, which may be difficult to treat. Because sexual activity may place a strain on your heart, your doctor will need to check whether you are fit enough to take Sildenafil Lupin.
    – Common trade names for glyceryl trinitrate tablets include Anginine and Lycinate. Common trade names for glyceryl trinitrate patches include Nitro-Dur, Transiderm-Nitro, Nitroderm TTS, and Minitran.
    – Common trade names for glyceryl trinitrate sprays include Nitrolingual and Glytrin. Trade names for glyceryl trinitrate injections include Glyceryl Trinitrate Concentrate and Glyceryl Trinitrate.
    – Common trade names for other nitrate preparations include Imdur Durules, Monodur Durules, Sorbidin, Isordil, Imtrate, Duride, Isomonit, Korel and Sodium Nitroprusside. There may be other trade names not listed here.
  • you are taking guanylate cyclase stimulators (GCS), such as Adepmas (riociguat).
    – GCS is a type of medicine used to treat high blood pressure in the blood vessels in the lungs caused by blood clots in the lungs (chronic thromboembolic pulmonary hypertension, CTEPH) or narrowing of the vessels that carry blood from the heart to the lungs (pulmonary arterial hypertension or PAH).
  • you have heart or blood vessel problems that make sexual intercourse inadvisable.
  • you have suffered a heart attack or stroke in the last 6 months.
  • you have severe liver problems.
  • you have blood pressure that is unusually high or low or is not effectively treated.
  • you have loss of vision in one or both eyes from an eye disease called non-arteritic anterior ischaemic optic neuropathy (NAION).
  • you have an eye disease called retinitis pigmentosa.
  • the packaging is torn or shows signs of tampering, or does not look quite right even if the tablets may look alright.
  • the expiry date on the pack has passed. If it has expired or is damaged, return it to your pharmacist for disposal.

Check with your doctor if you:

  • have any other medical conditions, such as:
    – allergies to any other medicines or any other substances such as foods, preservatives or dyes;
    – any other heart or blood vessel problems;
    – if you have previously had any sudden loss of eyesight in one or both eyes in the past;
    diabetes, especially if you also have eye problems;
    – kidney or liver problems;

    – any disease or deformity of your penis;
    – any bleeding disorder such as haemophilia;
    – a disease of the blood called sickle cell anaemia;
    – stomach ulcer;
    – colour vision problems;
    – if you have previously experienced sudden decrease or loss of hearing;
    – if you take any medicines for impotence or any other condition.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with Sildenafil Lupin and affect how it works. This includes

  • any medicines to treat high blood pressure in the vessels of the lungs (pulmonary arterial hypertension) including Tracleer (bosentan) or Revatio which also contains sildenafil.
  • taking any other treatment for impotence.

Medicines that may increase the effect of Sildenafil Lupin include:

  • cimetidine, erythromycin, saquinavir, ketoconazole, itraconazole, and ritonavir.

Medicines that may reduce the effect of Sildenafil Lupin include:

  • rifampicin and bosentan.

The effect of medicines that may be greatly increased by Sildenafil Lupin include:

  • riociguat, nitrate medicines (for example glyceryl trinitrate), alpha-blockers (for example doxazosin).

You may need different amounts of your medicine or you may need to take different medicines. Your doctor or pharmacist can tell you what to do if you are taking any of these medicines. They also have a more complete list of medicines to be careful with or avoid while taking Sildenafil Lupin.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect Sildenafil Lupin.
