Consumer Information
This information was provided by the drug’s manufacturer when this drug product was approved for sale in Canada. It is designed for consumers and care givers. It is a summary of information about the drug and will not tell you everything about the drug. Contact your doctor or pharmacist if you have any questions about the drug.
What the medication is used for
MAR-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 MAR-SILDENAFIL works only
with sexual stimulation. MAR-SILDENAFIL alone does not
increase your sex drive.
What it does
MAR-SILDENAFIL belongs to a class of medicine called phosphodiesterase type 5 (PDE5) inhibitors. Following sexual stimulation, MAR-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 MAR-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 MAR-SILDENAFIL with nitrate-containing 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 MAR-SILDENAFIL.
- MAR-SILDENAFIL is not to be used in men for whom sexual activity is inadvisable.
- Do not take MAR-SILDENAFIL with guanylate cyclase stimulators, such as riociguat.
What the medicinal ingredient is
sildenafil citrate.
What the non-medicinal ingredients are
microcrystalline cellulose, anhydrous dibasic calcium phosphate, croscarmellose sodium, magnesium stearate, hypromellose, titanium dioxide, lactose, triacetin, and FD & C Blue #2 aluminum lake.
What dosage form it comes in
MAR-SILDENAFIL is available as blue, biconvex, diamondshaped tablets marked ‘SIL on one side, and ‘25, 50, or 100’ on the other. Each tablet contains sildenafil citrate equivalent to either 25mg, 50mg or 100mg sildenafil.
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 MAR-SILDENAFIL talk to your doctor
or pharmacist if you:
- have heart problems (irregular heart beats, 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.

- have had a stroke
- have low blood pressure or uncontrolled high blood pressure

- 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.
MAR-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 MAR-SILDENAFIL and experience temporary, decrease, or permanent loss of vision, stop taking MAR-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 MAR-SILDENAFIL. 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 MAR-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 MAR-SILDENAFIL. Dizziness or altered vision can occur while using MAR-SILDENAFIL.
