What other drugs will affect sildenafil?

Even though the active ingredients are the same, if you’re switching from Pfizer’s brand-name Viagra to a generic form of sildenafil, it’s important to check that you’re purchasing tablets with a similar dosage to the one your healthcare provider prescribed. Sildenafil may also be sold under different brand names in other countries. Some of these Viagra generic names include: When it comes to drugs like Figral, Mazzogran, and Fildena vs. Viagra, they are all used for the same purpose: increasing blood flow to the penis. Their labels also state that these products contain sildenafil, so Mazzogran sildenafil 100mg should be equivalent to brand-name Viagra 100mg.

Warnings for people with certain health conditions

However, because these drugs have not been made in the U.S. and cleared by the FDA, it may be harder to assess the quality of their ingredients. Each country has its own set of regulations, and there’s always the chance the product you’re getting is not authentic if you buy it online from an international retailer. If you’re in the U.S. and looking for a cheaper alternative to Viagra, it’s best to stick with FDA-approved sildenafil. Sildenafil is also available in the United States as a liquid solution.

The history of branded Viagra

The only real difference between the two medications for ED is how much they cost. Viagra® is a well-known and widely used medication for treating erectile dysfunction (ED), one of the most common sexual dysfunctions in the world. Formulated as that iconic little blue pill, Viagra has the longest history of any FDA-approved ED treatment on the market today. Both generic sildenafil and Viagra work by increasing blood flow to your penis, making it easier for you to get and maintain an erection. Sildenafil belongs to a class of enzyme-inhibiting drugs called phosphodiesterase type 5 inhibitors, or PDE5 inhibitors.

Like the others in its class, sildenafil works by relaxing the muscle tissue inside the walls of your blood vessels, allowing the vessels to dilate, and improving blood flow throughout some parts of your body — including your penis. It's important to note that these erectile dysfunction medications aren't wonder drugs. They only work if you're sexually stimulated. But if you’ve got sexual stimulation and these pills, research shows that you have an effective, reliable erectile dysfunction treatment. If you’re curious about the history of the brand and generic names, here’s the quick version: Two years and many clinical trials later, in March of 1998, the new medication — now called Viagra — received approval from the Food and Drug Administration and hit the market as a prescription medication for the treatment of erectile dysfunction. dose of Viagra (the typical doses used for erectile dysfunction) as you can the same dose of generic sildenafil.

Stronger erections, better sex

Two years and many clinical trials later, in March of 1998, the new medication — now called Viagra — received approval from the Food and Drug Administration and hit the market as a prescription medication for the treatment of erectile dysfunction. As the first oral medication for ED, Viagra became incredibly popular. Large-scale TV ad campaigns lovegra sildenafil made the little blue pill famous. In 2005, the FDA approved sildenafil under the brand name Revatio® for treating pulmonary arterial hypertension — more on this later. Pfizer’s patent on Viagra expired in 2012 for countries outside the U.S., allowing other brands to produce and market their own generic Viagra medications containing sildenafil.

Viagra and other medications

Although Pfizer challenged the expired patent in the United States, sildenafil has since become widely available as a generic medication manufactured and marketed by various companies. Viagra is brand-name sildenafil that’s FDA-approved for ED, and what is the active ingredient in Viagra? But we suspect the question you really want to ask is whether one is made better, or safer — is generic sildenafil as good as Viagra for treating ED? Although some manufacturers may use their own brand name, most generic sildenafil products are labeled simply as “sildenafil.” Regardless, they do the same thing, offer the same benefits, and have the same risk of side effects. While a single tablet of Viagra is priced as high as $70 in the United States, generic drugs like sildenafil tablets are available for as little as $3 each when purchased online. Both Viagra and sildenafil work best when taken at least 30 minutes to an hour before sexual activity (and no more than four hours beforehand).

Why is this medication prescribed?

Selectivity is the ability of the drug to attach to the specific enzyme PDE 5 found in penile tissues. Vardenafil (Levitra) is more selective than sildenafil and tadalafil (Cialis) to PDE5, which again means a lower dose is needed with potentially less side effects. Tadalafil is very specific for PDE5 and is also very specific for the enzyme PDE11. Unfortunately, we don’t know much about PDE11, which is found in the heart, in the pituitary gland in the brain and in the testicles. Pharmacokinetics, half-life, is how long the medication stay s in the blood.

Sildenafil Tablets or Oral Suspension for PAH

This means that vardenafil (Levitra) should act longer than sildenafil (Viagra) but the clinical significance is not known. Tadalafil (Cialis) has the longest half-life and allows you to take the medication and not relate the sexual activity to the immediate use of the medication. The drawback is if you need nitrates after using tadalafil (Cialis), this medication lasts a long time in your blood stream and may place you at a higher risk. Younger people might do well treated with tadalafil, (Cialis) while older people with other health issues might be better off using sildenafil (Viagra) or vardenafil (Levitra) but more data are needed. The side effects of vardenafil (Levitra) are potentially less than sildenafil (Viagra), but more data are needed. You can take Viagra or generic sildenafil with or without food, but should avoid taking either with a high-fat meal, as it can make both medications take longer to take effect in your body.

Spontaneous sex for less than $2/day If you’ve searched the web for information about ED medication, you’ve no doubt seen Viagra® mentioned alongside a drug called sildenafil. Given how often they’re interchanged, you might be wondering if there are any differences when it comes to sildenafil vs. Viagra. Put simply, Viagra is the FDA-approved brand-name version of sildenafil, a prescription medication for ED. Sildenafil is the main active ingredient in Viagra.

How to relieve Viagra side effects

Like the store-brand salad dressing made with the same ingredients as its brand-name equivalent, sildenafil is just as good as the “little blue pill,” but cheaper. Keep reading to learn more about the similarities and differences between these drugs, and how to choose the best one for you. Sildenafil citrate (often shortened to “sildenafil”) is the main ingredient in Viagra. After parent company Pfizer’s patent expired, other manufacturers were allowed to manufacture generic Viagra under the name of its active ingredient, sildenafil. The terms are pretty much interchangeable, the way you might say “Kleenex®” to refer to a tissue. Instead, let your healthcare provider know — they may recommend adjusting your dosage or trying a different ED medication.

Drug Class	Interaction Effect	Clinical Implication	Example Drugs
Nitrates	Severe hypotension	Contraindicated	Nitroglycerin, Isosorbide dinitrate
Alpha-blockers	Increased hypotension	Dose adjustment required	Tamsulosin, Doxazosin
CYP3A4 inhibitors	Increased sildenafil levels	Risk of side effects	Ketoconazole, Ritonavir
Other PDE5 inhibitors	Additive effects	Avoid combining	Tadalafil, Vardenafil

Although sildenafil works similarly to other PDE5 inhibitors like vardenafil (Levitra), the two have different dosages.

• Sildenafil citrate 100mg tablets are used to treat erectile dysfunction in men.
• The usual recommended dose is 100mg taken about an hour before activity.
• Sildenafil works by increasing blood flow to the penis during arousal.
• This medication should not be used with nitrate drugs due to risk of dangerous interactions.
• Common side effects include headache, flushing, upset stomach, and nasal congestion.
• Do not take sildenafil more than once in a 24-hour period.
• Sildenafil can cause hypotension, especially when combined with certain medications.
• It is available by prescription and should be used under medical supervision.
• Patients with heart problems should consult their doctor before use.
• Sildenafil should be stored at room temperature, away from moisture and heat.
• Alcohol can increase the risk of side effects when taking sildenafil.
• Sildenafil may cause vision changes such as blue tinge or increased sensitivity to light.

Vardenafil, for example, uses a lower dose, although not necessarily stronger than Viagra. Since brand-name Viagra and generic sildenafil contain sildenafil and come in the same range of dosages, both medications can cause the same range of side effects.

Parameter	Value	Time to Peak	Notes
Absorption Rate	Rapid, oral administration	30-120 min	Depends on food intake
Half-life	Approximately 4 hours	-	Duration of effect
Bioavailability	About 40%	-	Percentage of drug reaching systemic circulation
Metabolism	Liver (via CYP3A4 enzyme)	-	Mainly via hepatic pathways

We’ve divided the side effects into two groups: common and rare.

Pregnancy & Lactation

Viagra comes in three dosages: 25mg, 50mg, and 100mg. Sildenafil pills similarly come in 25mg, 50mg, and 100mg tablets. However, sildenafil can also come in 20mg when it is sold as the generic version of Revatio. Revatio is FDA-approved to treat a type of high blood pressure in the lungs (called pulmonary arterial hypertension, or PAH), but it can be prescribed off-label for ED.So, is sildenafil 20mg the same as Viagra 25mg? While each tablet of generic Revatio is 20mg, when used for ED, you could be prescribed multiple tablets at once, making 40mg, 60mg, 80mg, and 100mg doses possible. We’ve also included a note about serious drug interaction risks that you should seek to avoid and alert your healthcare provider to before taking sildenafil.

Before Using

In a recent study on men with erectile dysfunction and diabetes, vardenafil (Levitra) improved their erectile dysfunction. Tadalafil (Cialis) is as effective as sildenafil (Viagra), and vardenafil (Levitra) with similar side effects except for back pain that occurs occasionally with tadalafil, probably because of the long half-life. Many people stop taking drugs because they are experiencing side effects, they no longer have a partner, or they are worried about safety. Sexual activity is not a major contributor to the risk of a heart attack. Sexual activity, with or without sildenafil (Viagra) increases the chance of an MI during sexual activity by only 0.1%.

Is there a “female Viagra”?

If pills fail, there are vacuum devices, Muse, injections, bypass surgery and implants. The patient making a presentation has had penile bypass surgery. In addition he takes testosterone and sildenafil as needed. This is a classic example of why people with ED need complete care: a psychological exam, history and physical exam, and diagnostic studies with long term follow-up care. Patients with ED should not just be prescribed sildenafil (Viagra) and then be lost to follow-up.
