1. What Silandyl is and what it is used for

Silandyl contains the active substance sildenafil, which belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. Silandyl works by helping to relax the blood vessels in the penis, increasing blood flow to the penis during sexual stimulation. Silandyl helps achieve an erection only if the patient is sexually stimulated.
Silandyl is used to treat men with erectile dysfunction, sometimes known as impotence. This is defined as the inability to obtain or maintain a penile erection sufficient for sexual intercourse.

2. Important information before taking Silandyl

When not to take Silandyl:

• if the patient is allergic to sildenafil or any of the other ingredients of this medicine (listed in section 6).
• if the patient is taking nitrates, as their concomitant use may cause dangerous lowering of blood pressure. If the patient is taking any of these medicines, they must inform their doctor; these medicines are often used to relieve symptoms of angina (chest pain). In case of doubt, consult a doctor or pharmacist.
• if the patient is taking medicines that release nitric oxide (e.g. amyl nitrate, so-called "poppers"), as their simultaneous use may cause dangerous lowering of blood pressure.
• if the patient has serious heart or liver problems.
• if the patient has recently had a stroke or heart attack, or if they have low blood pressure.
• if the patient suffers from rare hereditary eye diseases (such as retinitis pigmentosa).
• if the patient has ever experienced vision loss due to non-arteritic anterior ischemic optic neuropathy (NAION).
• if the patient is taking riociguat. This medicine is used to treat pulmonary hypertension (i.e. high blood pressure in the lungs) and chronic thromboembolic pulmonary hypertension (i.e. high blood pressure in the lungs caused by blood clots). PDE5 inhibitors, such as Silandyl, have been shown to enhance the blood pressure-lowering effect of this medicine. If the patient is taking riociguat or is unsure, they must inform their doctor.

Warnings and precautions
Before starting treatment with Silandyl, consult a doctor, pharmacist, or nurse:

• if the patient has sickle cell anemia (a disorder affecting red blood cells), leukemia (a blood cancer), or multiple myeloma (a cancer of the bone marrow).
• if the patient has been diagnosed with anatomical penile deformity or Peyronie's disease.
• if the patient has heart problems. The doctor should carefully assess whether the patient's heart condition allows for the additional strain associated with sexual activity.
• if the patient has a stomach ulcer or bleeding disorders (such as hemophilia).
• if the patient experiences sudden worsening of vision or sudden vision loss, they must stop taking Silandyl immediately and contact their doctor without delay.

Silandyl must not be used concomitantly with other oral or topical treatments for erectile dysfunction.
Silandyl must not be used together with medicines used to treat pulmonary arterial hypertension (PAH) containing sildenafil or other PDE5 inhibitors.
Silandyl should not be used by patients in whom erectile dysfunction has not been diagnosed.
Silandyl is not intended for use in women.

Special considerations in patients with renal or hepatic impairment
Patients with impaired kidney or liver function should inform their doctor, who may decide to prescribe a lower dose of the medicine.

Children and adolescents
Silandyl must not be used in individuals under 18 years of age.

Silandyl and other medicines
Inform the doctor or pharmacist about all medicines currently taken or recently taken, as well as any medicines the patient plans to take.
Silandyl oral disintegrating tablets may interact with certain medicines, particularly those used to treat chest pain.
In case of a medical emergency, inform the doctor, pharmacist, or nurse that the patient has taken Silandyl and when it was taken. Do not take Silandyl together with other medicines without the doctor's approval.
Do not take Silandyl if the patient is taking nitrate-containing medicines, as their concomitant use may cause dangerous lowering of blood pressure. Always inform the doctor, pharmacist, or nurse if the patient is taking medicines commonly used to treat angina (chest pain).
Do not take Silandyl if the patient is taking medicines that release nitric oxide (e.g. amyl nitrate), as their concomitant use may cause dangerous lowering of blood pressure.
If the patient is taking protease inhibitors used in the treatment of HIV infection, initiation of therapy with the lowest dose of Silandyl (25 mg) is recommended.
In some patients taking alpha-blockers for high blood pressure or benign prostatic hyperplasia, dizziness or lightheadedness may occur, which may be symptoms of orthostatic hypotension—low blood pressure upon rapid standing or sitting up. Such symptoms have occurred in some patients taking Silandyl together with alpha-blockers. These symptoms are most likely to occur within 4 hours after taking Silandyl.
To reduce the risk of such symptoms, the patient should be on a stable dose regimen of their alpha-blocker before starting Silandyl. The doctor may decide to initiate treatment with a low dose (25 mg) of Silandyl.
Inform the doctor or pharmacist if the patient is already taking riociguat.

Silandyl with food, drink, and alcohol
Silandyl may be taken with or without food. However, taking Silandyl after a heavy meal may delay the onset of its action.
The ability to achieve an erection may be temporarily impaired after alcohol consumption. To maximize the effectiveness of Silandyl, significant alcohol intake should be avoided before taking the medicine.

Pregnancy, breastfeeding, and fertility
Silandyl is not indicated for use in women.

Driving and operating machinery
Silandyl may cause dizziness and visual disturbances. Patients should understand how they react to Silandyl before driving vehicles or operating machinery.

3. How to take Silandyl

This medicine should always be taken as directed by a physician or pharmacist. In case of
doubt, consult a physician or pharmacist. The recommended starting dose is 50 mg.
Silandyl must not be taken more than once a day.
Silandyl should be taken approximately one hour before planned sexual activity. Sildenafil in the form of orodispersible tablets is intended for oral administration without water. However, the patient may also take sildenafil with water.

Instructions for use
Warning: Do not handle the orodispersible tablets with wet hands!
a) Take the sachet in your hand, locate the arrow mark

at the top of the sachet and hold it with this side facing upwards. The sachet is not sealed at this point.
b) Gently tear apart both sides of the sachet.

Hold each side of the sachet with one hand, between the thumb and index finger.
c) Carefully pull both sides of the sachet in opposite directions until they separate.
At this point, the tablet will be visible, lying on one of the separated parts of the sachet.

d) With dry fingers, take the tablet, remove it from the sachet and immediately place it in the mouth, on the tongue.
The tablet will dissolve quickly, making it easy to swallow.

If the effect of Silandyl seems too strong or too weak, consult a physician or pharmacist. Silandyl helps achieve an erection only when accompanied by sexual stimulation. The time required for Silandyl to take effect varies between individuals, but usually ranges from half an hour to one hour. The effect of Silandyl may be delayed if taken after a heavy meal.

If an erection does not occur after taking Silandyl, or if the duration of erection is insufficient for sexual intercourse, inform your physician.

Taking more than the recommended dose of Silandyl
Adverse effects may occur more frequently and be more severe.
Taking a dose higher than 100 mg does not increase the effectiveness of the medicine.
Do not take more orodispersible tablets than prescribed by your physician.
Contact your physician if you have taken more tablets than recommended.

If you have any further doubts regarding the use of this medicine, consult your physician, pharmacist, or nurse.
