Consumer Information
Information about the product including what the product is used for, dosage, warnings, proper use and side effects. This summary will not tell you everything about the product. Contact your healthcare professional if you have any questions about the product.
What the medication is used for
ACCEL-SILDENAFIL (sildenafil citrate) is a treatment
for erectile dysfunction in male adults. This is when a man
cannot achieve or maintain a hard, erected penis for
satisfactory sexual activity.
It is important to note that ACCEL-SILDENAFIL works
only with sexual stimulation. ACCEL-SILDENAFIL
alone does not increase your sex drive.
What it does
ACCEL-SILDENAFIL belongs to a class of medicine called phosphodiesterase type 5 (PDE5) inhibitors. Following sexual stimulation, ACCEL-SILDENAFIL works by helping to relax the blood vessels in your penis by allowing blood to flow into your penis. This results in improved erectile function.
When it should not be used
- If you are taking any medicines containing nitrates in any form (oral, sublingual [under the tongue], skin patch, or by inhalation [spray]). Although ACCEL-SILDENAFIL is used occasionally, nitrates must never be used. Nitrates are found in many prescription medicines that are used in the treatment of angina pectoris (chest pain due to heart disease), such as nitroglycerin, isosorbide mononitrate, or isosorbide dinitrate. If you do not understand what nitrates are, or are unsure about whether a medication you are taking is a “nitrate”, ask your doctor or pharmacist.
If you take ACCEL-SILDENAFIL with nitratecontaining medicines or any other nitrates (e.g., amyl nitrite “poppers”), your blood pressure could suddenly drop to a life-threatening level. You could get dizzy, faint, or even have a heart attack or stroke.
- If you have loss of vision in one or both eyes from an eye disease called non-arteritic anterior ischaemic optic neuropathy (NAION)
- If you have ever had an allergic reaction to sildenafil citrate or the nonmedicinal ingredients in ACCEL-SILDENAFIL.
- ACCEL-SILDENAFIL is not to be used in men for whom sexual activity is inadvisable.
- Do not take ACCEL-SILDENAFIL with guanylate cyclase stimulators, such as riociguat.
What the medicinal ingredient is
Sildenafil citrate.
What the non-medicinal ingredients are
Calcium hydrogen phosphate anhydrous, indigo carmine aluminium lacquer, macrogol 3350, magnesium stearate, microcrystalline cellulose, polyvinilic alcohol, sodium croscarmellose, talc and titanium dioxide.

Warnings and precautions
This medicine has been prescribed for you personally
and you should not pass it on to others. It may harm
them, even if their symptoms are the same as yours.
BEFORE you use ACCEL-SILDENAFIL talk to your
doctor or pharmacist if you:
- have heart problems (irregular heartbeats, angina, chest pain, or had a heart attack). If you have heart problems, ask your doctor if your heart is healthy enough to handle the extra strain of having sex. If you have chest pain, dizziness or nausea during sex, stop exerting yourself. You should not use nitrates but you should seek immediate medical assistance.
- are 65 years of age or over
- have had a stroke
- have low blood pressure or uncontrolled high blood pressure
- have liver or kidney problems
- have sickle cell anemia (abnormality of the red blood cells), multiple myeloma (cancer of the bone marrow) or leukaemia (cancer of the white blood cells)
- are allergic to sildenafil or any of the other ingredients of ACCEL-SILDENAFIL tablets
- have a deformed penis or Peyronie’s disease
- have ever had an erection that lasted more than 4 hours
- have stomach ulcers or other bleeding problems.
- have a rare inherited eye disease called retinitis pigmentosa
- have had temporary, decrease, or permanent loss of vision in one or both eyes, including a condition called Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION). The specific type of vision decrease or loss, called non-arteritic anterior ischemic optic neuropathy (NAION), seems to occur rarely when blood flow to the optic nerve is reduced or blocked. Vision decrease or loss may be partial or complete, in one or very occasionally both eyes. While in some cases the condition may improve over time, it can also be irreversible.
- Rare but serious skin reactions of Stevens-Johnson’s Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) have been reported during the post-marketing period.
ACCEL-SILDENAFIL does not protect against sexually transmitted diseases (STD), including Human Immunodeficiency Virus (HIV).
Alcohol consumption may decrease the ability to get an erection.
If you are taking ACCEL-SILDENAFIL and experience temporary, decrease, or permanent loss of vision, stop taking ACCEL-SILDENAFIL and call your doctor.
In case of chest pain occurring during or after sexual activity you should not use nitrates but you should seek immediate medical assistance.
Sudden decrease or loss of hearing has been reported in a few number of postmarketing and clinical trial cases with the use of PDE5 inhibitors, including sildenafil citrate. It has not been established whether these are related directly to the use of these medications or to other factors. If you experience these symptoms, stop taking ACCEL-SILDENAFIL and call your doctor.
Driving and using machines: Before you perform tasks which may require special attention, wait until you know how you respond to ACCEL-SILDENAFIL. Dizziness or altered vision can occur while using ACCELSILDENAFIL.

Proper use of this medication
Usual Dose
Your doctor can determine the dose that works best for you.
Always take ACCEL-SILDENAFIL as prescribed by your
doctor. You should speak with your doctor or pharmacist if
you are unsure. A dose above 100 mg per day is not
recommended.
Swallow the tablet whole, with some water.

lowest dose (25 mg) of ACCEL-SILDENAFIL.
How to optimize your use of ACCEL-SILDENAFIL:
You should take ACCEL-SILDENAFIL approximately 30
to 60 minutes before sexual activity. You can engage in
sexual activity within 30 minutes of taking the tablet and
for up to 4 hours. The amount of time it takes to have an

sexual stimulation is required for ACCEL-SILDENAFIL to work.

every time. If ACCEL-SILDENAFIL did not work for
you on one occasion, try again on another day. You will
learn how well ACCEL-SILDENAFIL works for you
through your personal experience. The first few times may
be charged with emotion or anxiety. If after a few separate
attempts, you do not get the results you expect, talk to your
doctor.
Overdose
You should not take more than one dose of ACCEL-SILDENAFIL per day.
If you have taken more ACCEL-SILDENAFIL than you
