But does the colour and shape of your pill make a difference in the effectiveness of the treatment?

When Viagra was first approved as a treatment for ED in 1998, it was marketed as “the little blue pill”. The small, blue, diamond-shaped pill was patented by Viagra, meaning that both its appearance and active ingredient were exclusive to Viagra and couldn’t be copied by other manufacturers.

After Pfizer’s patent for Viagra expired in 2013, sildenafil (the active ingredient in Viagra) was made more widely available for manufacturing by other companies.

You can keep it at room temperature (up to 86ºF). Or, you can put it in the refrigerator (though be sure not to let it freeze). Once you get the oral suspension from the pharmacy, the medication is good for 60 days. The pharmacist usually writes the expiration date on the label on the bottle. Throw the medication away after this date, even if there's still medication left over.

Sildenafil side effects

Sildenafil (Revatio) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options. Risk factors: Certain heart problems Low fluids in the body (dehydration) Low blood pressure at rest Also taking erectile dysfunction medications Also taking blood pressure medications Also taking nitrates like nitroglycerin Sildenafil (Revatio) can cause your blood pressure to drop. It can make you feel dizzy, tired, or lightheaded.

Before taking sildenafil,

This side effect is usually mild and doesn't last long. Tell your prescriber and pharmacist about all the medications you take. You're at risk of having this side effect if you also take other medications that lower blood pressure. You can't take sildenafil (Revatio) if you also take nitrates like nitroglycerin. This is because of the risk of a severe drop in blood pressure. The main difference between sildenafil and Viagra is that Viagra is branded, and sildenafil is the generic, or unbranded, version of it. As both sildenafil and Viagra contain the same active ingredient, sildenafil citrate, they are both effective treatments for men with ED. All generic medication has to contain the same active ingredient to ensure it works in the same way as its brand-name equivalent. Branded medication is often more expensive than generic medication. Any new brand-name medication will pitch the price relative to the amount of initial research needed to develop and prepare the treatment for marketing approval. Generic medication can typically be 20-90% cheaper than its brand-name equivalent because of this. The other important factor in pricing is competition: as sildenafil is widely available for manufacture, the price is more competitive (and therefore cheaper). A 2019 study was conducted into the effectiveness of generic medication, which found that there was no difference between how generic and brand-name medication works.

Even though generic sildenafil is unbranded, it is still an effective treatment for ED and works in the same way as Viagra. Both Viagra and sildenafil are considered effective treatments for ED. The colour and shape of the pill have no impact on how effective the treatment is. The main difference between generic medication, such as sildenafil, and brand-name medication, such as Viagra, is the purchase price and the appearance of the pill.

What is Sildenafil (Viagra)?

After you take sildenafil (Revatio), sit down for the first few minutes to help prevent dizziness. Get emergency help if you feel like you might pass out, feel confused, have a fast heartbeat, or have chest pain. These can be serious signs of very low blood pressure. Sildenafil (Revatio) isn't recommended if you have pulmonary vascular occlusive disease (PVOD). This is a rare condition that affects the blood flow between your lungs and heart.

Erectile dysfunction

Sildenafil (Revatio) hasn't been studied in people with PVOD. But it's possible that it can make this condition worse. Tell your care team if you have any shortness of breath, a cough that doesn't go away, tiredness, or chest pain. These could be signs of fluid buildup in your lungs, and your care team should check you for PVOD. Risk factors: PAH due to connective tissue disease Also taking the blood thinner called warfarin This is more likely to happen if you take the blood thinner warfarin.

Pulmonary hypertension

Tell your care team if you start getting nosebleeds often. And get medical attention if you have a nosebleed that you can't stop. Risk factors: History of eye problems, including a "crowded" optic disc Although rare, reports of eye damage might be linked to taking PDE5 inhibitors like sildenafil (Revatio). This eye damage is called non-arteritic anterior ischemic optic neuropathy (NAION). It happens when there's poor blood flow to the nerves in the eye. Approval: 1998INDICATIONS AND USAGEAdultsSildenafil tablets are a phosphodiesterase-5 (PDE-5) inhibitor indicated for the treatment of pulmonary arterial hypertension (PAH) (World Health Organization [WHO] Group I) in adults to improve exercise ability and delay clinical worsening.

Symptoms include sudden loss of vision in one eye, eye pain, and headache. It might lead to permanent vision loss if not treated. Before you start sildenafil (Revatio), tell your prescriber about your full medical history. This medication isn't recommended for people with an eye problem called retinitis pigmentosa. The risk of this eye damage might also be higher if an eye specialist has told you that you have a "crowded" optic disc.

Raynaud's phenomenon

If you have sudden vision changes or lose vision in one or both eyes while taking sildenafil (Revatio), go to the emergency room or call an eye specialist right away. They can check out what's going on. Some people who took sildenafil (Revatio) reported hearing loss. This can sometimes happen with ringing in the ears (tinnitus) and dizziness. It isn't clear whether these effects are related to the medication or to other factors.

Does sildenafil interact with foods or drinks?

Let your prescriber know if you notice changes in your hearing in one or both ears while taking sildenafil (Revatio). Don't take sildenafil (Revatio) with other PDE5 inhibitors. This includes sildenafil (Viagra) for erectile dysfunction (ED). Taking more than one PDE5 inhibitor at the same time isn't recommended. It might raise your risk of side effects, like very low blood pressure, dizziness, headaches, and flushing.
