Contents of the pack and other information
Maxon contains the active substance sildenafil, which belongs to a group of medicines called phosphodiesterase type 5 inhibitors (PDE5). It works by widening the blood vessels in the penis, allowing blood to flow in when you are sexually stimulated. Sildenafil will only help you to get an erection if you are sexually stimulated.
Sildenafil is used to treat erectile dysfunction in adult men, sometimes also called impotence. This is when a man cannot get, or keep, a hard erection that is sufficient for satisfactory sexual activity.
Do not take Maxon
Warnings and precautions
Consult your doctor, pharmacist, or nurse before taking sildenafil:
It is not recommended to use sildenafil in combination with any other oral or local treatment for erectile dysfunction.
You must not take sildenafil with treatments for pulmonary arterial hypertension (PAH) that contain sildenafil or any other PDE5 inhibitor.
You must not take sildenafil if you do not have erectile dysfunction.
The use of sildenafil is not indicated in women.
Special considerations in patients with kidney or liver problems
You should inform your doctor if you have kidney or liver problems. Your doctor may decide to reduce your dose.
Children and adolescents
The use of sildenafil is not indicated in persons under 18 years of age.
Other medicines and Maxon
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
Sildenafil tablets may interfere with some medicines, especially those used to treat angina. In the event of a medical emergency, you should inform your doctor, pharmacist, or nurse that you are taking sildenafil and when you took it. Do not take sildenafil with other medicines unless your doctor advises you to.
You must not take sildenafil if you are taking medicines called nitrates, as the combination of these medicines can lead to a dangerous decrease in your blood pressure. Always inform your doctor, pharmacist, or nurse if you are taking any of these medicines, which are often used to relieve angina pectoris (or "chest pain").
You must not take sildenafil if you are taking medicines called nitric oxide donors, such as amyl nitrite ("poppers"), as the combination of these medicines can also lead to a dangerous decrease in your blood pressure.
Tell your doctor or pharmacist if you are taking riociguat.
If you are taking medicines known as protease inhibitors, such as those used to treat HIV, your doctor may recommend that you start with the lowest dose (25 mg) of sildenafil.
Some patients who are receiving an alpha-blocker, a medicine used to treat high blood pressure or prostate enlargement, may experience dizziness or lightheadedness that can be caused by a decrease in blood pressure when sitting or standing up quickly. Some patients have experienced these symptoms when taking sildenafil with alpha-blockers. This is more likely to happen within 4 hours after taking sildenafil. To reduce the likelihood of these symptoms, you should be taking your daily dose of the alpha-blocker regularly before starting on sildenafil. Your doctor may advise you to start with the lower dose (25 mg) of sildenafil.
Tell your doctor or pharmacist if you are taking medicines containing sacubitril/valsartan, used to treat heart failure.

Sildenafil will only help you to get an erection if you are sexually stimulated. The time it takes for sildenafil to work varies from person to person, but it normally takes between 30 minutes and 1 hour. The effect of sildenafil may be delayed if you take it with a large meal.
