Patient leaflet - Hezkue 12.5 mg/actuation, Oromucosal spray, suspension

1. What Hezkue® is and what is it used for

Hezkue® contains the active substance sildenafil which belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. It works by helping to relax the blood vessels in your penis, allowing blood to flow into your penis when you get sexually excited. Hezkue® will only help you to get an erection if you are sexually stimulated.

Hezkue® is a treatment for adult men with erectile dysfunction, sometimes known as impotence. This is when a man cannot get, or keep a hard, erect penis suitable for sexual activity.

2. What you need to know before you take Hezkue®

Do not take Hezkue®:

  • If you are allergic to sildenafil or any of the other ingredients of this medicine (listed in section 6).
  • If you are taking medicines called nitrates, as the combination may lead to a dangerous fall in your blood pressure. Tell your doctor if you are taking any of these medicines which are often given for relief of angina pectoris (or “chest pain”). If you are not certain, ask your doctor or pharmacist.
  • If you are using any of the medicines known as nitric oxide donors such as amyl nitrite (“poppers”), as the combination may also lead to a dangerous fall in your blood pressure.
  • If you have a severe heart or liver problem.
  • If you have recently had a stroke or a heart attack, or if you have low blood pressure.
  • If you have certain rare inherited eye diseases (such as retinitis pigmentosa).
  • If you have ever had loss of vision due to non-arteritic anterior ischaemic optic neuropathy (NAION).
  • If you are taking Riociguat. This medicine is used to treat pulmonary arterial hypertension (i.e., high blood pressure in the lungs) and chronic thromboembolic pulmonary hypertension (i.e., high blood pressure in the lungs secondary to blood clots). PDE5 inhibitors, such as Hezkue® has been shown to increase the hypotensive effects of this medicine. If you are taking Riociguat or are unsure tell your doctor.

Warnings and precautions

Check with your doctor before taking Hezkue®:

  • If you have sickle cell anaemia (an abnormality of red blood cells), leukaemia (cancer of blood cells), multiple myeloma (cancer of bone marrow).
  • If you have a deformity of your penis or Peyronie’s Disease.
  • If you have problems with your heart. Your doctor should carefully check whether your heart can take the additional strain of having sex.
  • If you currently have a stomach ulcer, or a bleeding problem (such as haemophilia).
  • If you experience sudden decrease or loss of vision, stop taking Hezkue® and contact your doctor immediately.

You should not use Hezkue® with any other oral or local treatments for erectile dysfunction.

You should not use Hezkue® with treatments for pulmonary arterial hypertension (PAH) containing sildenafil or any other PDE5 inhibitors.

You should not take Hezkue® if you do not have erectile dysfunction.

You should not take Hezkue® if you are a woman.

Special considerations for patients with kidney or liver problems

You should tell your doctor if you have kidney or liver problems. Your doctor may decide on a lower dose for you.

Children and adolescents

Do not give this medicine to children and adolescents under 18 years of age.

Other medicines and Hezkue®

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Hezkue® may interfere with some medicines, especially those used to treat chest pain. In the event of a medical emergency, you should tell your doctor, pharmacist or nurse that you have taken Hezkue® and when you did. Do not take Hezkue® with other medicines unless your doctor tells you that you can.

You should not take Hezkue® if you are taking medicines called nitrates, as the combination of these medicines may lead to a dangerous fall in your blood pressure. Always tell your doctor, pharmacist or nurse if you are taking any of these medicines that are often used for the relief of angina pectoris (or “chest pain”).

You should not take Hezkue® if you are using any of the medicines known as nitric oxide

donors such as amyl nitrite (“poppers”) as the combination may also lead to a dangerous fall in your blood pressure.

Tell your doctor or pharmacist if you are already taking Riociguat.

If you are taking medicines known as protease inhibitors, such as for the treatment of HIV, your doctor may start you on the lowest dose (1 ml is equivalent to 25 mg of sildenafil) of Hezkue®.

Some patients who take alpha-blocker therapy for the treatment of high blood pressure or prostate enlargement may experience dizziness or light-headedness, which may be caused by low blood pressure upon sitting or standing up quickly. Certain patients have experienced these symptoms when taking Hezkue® with alpha-blockers. This is most likely to happen within 4 hours after taking Hezkue®. To reduce the chance that these symptoms might happen, you should be on a regular daily dose of your alpha-blocker before you start Hezkue®. Your doctor may start you on a lower dose (1 ml is equivalent to 25 mg of sildenafil) of Hezkue®.

Tell your doctor or pharmacist if you are taking medicines containing sacubitril/valsartan, used to treat heart failure.

Hezkue® with food and drink and alcohol

Hezkue® can be taken with or without food. However, you may find that Hezkue® takes longer to start working if you take it with a heavy meal.

Drinking alcohol can temporarily impair your ability to get an erection. To get the maximum benefit from your medicine, you are advised not to drink excessive amounts of alcohol before taking this medicine.

Pregnancy and breast-feeding

Hezkue® is not indicated for use in women.

Hezkue® can cause dizziness and can affect vision. You should be aware of how you react to medicine before you drive or use machinery.

Patients on low sodium diets can be informed that this medicinal product is essentially ‘sodium-free’.

3. How to take Hezkue®

The recommended dose is 2 ml equivalent to 50 mg sildenafil (4 pumps). Each press of the dosing pump releases 0.5 ml of suspension containing 12.5 mg of sildenafil.

If this medicine does not help you to get an erection, or if your erection does not last long enough for you to complete sexual intercourse you should tell your doctor. Your doctor may then recommend a decrease or increase of the dose to 1 ml of the suspension equivalent to 25 mg (2 pumps), or 4 ml of suspension equivalent to 100 mg (8 pumps).

You should take Hezkue® about an hour before you plan to have sex. Hezkue® should not be taken more than once a day.

Do not take Hezkue® together with other medications that contain sildenafil.
