Sildenafil treats PAH by relaxing the blood vessels in the lungs to allow blood to flow easily.
This won’t necessarily affect you, but it may be a problem if you also take a blood pressure medication. A sudden drop in blood pressure can make you feel dizzy, fall, black out, or even cause more serious cardiac issues. All PDE5 inhibitors can lower your blood pressure. Nitrate medications, such as nitroglycerin (Nitrostat), can have dangerous interactions with PDE5 inhibitors. Nitrate medications are commonly given to people with heart conditions like angina or high blood pressure.
If you take a nitrate medication, you should never take ED medications at the same time.

Sildenafil comes as a tablet and suspension (liquid) to take by mouth. If you are taking sildenafil to treat erectile dysfunction, follow your doctor's directions and the guidelines in this paragraph. Take sildenafil as needed before sexual activity.
How to take it: Vardenafil can be taken with or without food. But high-fat foods can delay vardenafil's absorption and lower its effectiveness. Ideally, try to wait 1 to 2 hours after eating before you take it. If that’s not possible, stick to a light, low-fat meal. You can take it as needed for occasional ED symptoms.
How fast it works: Vardenafil can start working in as quickly as 15 minutes, but peak effects can take up to 1 hour. Then, it will keep working for 4 to 5 hours. Typical dose: The typical starting dosage of vardenafil is one 10 mg tablet. It can be cut back to 5 mg or increased to a maximum of 20 mg. Vardenafil is available as a traditional pill that you swallow and a rapidly dissolving pill (which gets to work faster).
Stendra is a newer ED medication that works similarly to Viagra, Cialis, and vardenafil. How to take it: Avanafil comes in a pill, which food doesn’t affect. How fast it works: Avanafil works a little faster on average than the other ED medications. The usual starting dose of 100 mg works within 15 minutes. With a lower dose, you’ll need to wait about 30 to 45 minutes. The best time to take sildenafil is about 1 hour before sexual activity, but you can take the medication any time from 4 hours to 30 minutes before sexual activity.
Sildenafil (Viagra) is used to treat erectile dysfunction (impotence; inability to get or keep an erection) in men. Sildenafil (Liqrev, Revatio) is used to improve the ability to exercise in adults (Liqrev, Revatio) and children 1 year of age and older (Revatio) with pulmonary arterial hypertension (PAH; high blood pressure in the vessels carrying blood to the lungs, causing shortness of breath, dizziness, and tiredness). Sildenafil is in a class of medications called phosphodiesterase (PDE) inhibitors. Sildenafil treats erectile dysfunction by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection. Sildenafil usually should not be taken more than once every 24 hours.
If you have certain health conditions or are taking certain medications, your doctor may tell you to take sildenafil less often.
| Ingredient | Source | Purpose | Common Uses |
|---|---|---|---|
| Sildenafil | Synthetic pharmaceutical | Enhances blood flow during arousal | Erectile dysfunction |
| Tadalafil | Synthetic pharmaceutical | Longer-lasting erection | Erectile dysfunction |
| Avanafil | Synthetic pharmaceutical | Rapid onset effect | Erectile dysfunction |
| L-arginine | Amino acid | Boosts nitric oxide production | Viagra alternatives |
| Yohimbine | Natural extract | Improves blood circulation | Libido enhancement |
You can take sildenafil with or without food.
However, if you take sildenafil with a high-fat meal, it will take longer for the medication to start to work. If you are taking sildenafil to treat PAH, you will probably take sildenafil three times a day with or without food. Take sildenafil at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Do not take more or less of it or take it more often than prescribed by your doctor. Shake the liquid well for 10 seconds before each use to mix the medication evenly. Use the oral syringe provided with your medication to measure and take your dose. Follow the manufacturer's directions to use and clean the oral syringe. Do not mix the liquid with other medications or add anything to flavor the medication. If you are taking sildenafil for erectile dysfunction, your doctor will probably start you on an average dose of sildenafil and increase or decrease your dose depending on your response to the medication.
This improves blood flow, which allows for an erection to last longer. Herbal products and dietary supplements that claim to be alternatives for ED aren’t regulated by the FDA. So it’s hard to determine which is best or if they’re even safe and effective. If you’re experiencing ED symptoms, it’s a good cenforce100 idea to speak with a healthcare professional about your treatment options. Like all medications, ED medications also carry a risk of side effects.
Speak with a healthcare professional about potential side effects and whether these medications would be safe for you to take. Phosphodiesterase 5 (PDE5) inhibitors are a class of medications used to treat erectile dysfunction (ED). The available PDE5 inhibitors include sildenafil (Viagra), tadalafil (Cialis), vardenafil (previously sold as Levitra and Staxyn), and avanafil (Stendra). Currently, one PDE5 inhibitor isn’t considered the best for ED. The best ED medication for you depends on many factors such as how often you plan to use it, potential side effects, and how much they cost. Tell your doctor if sildenafil is not working well or if you are experiencing side effects. If you are taking sildenafil for PAH, you should know that sildenafil controls PAH but does not cure it.
Continue to take sildenafil even if you feel well. Do not stop taking sildenafil without talking to your doctor. Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. tell your doctor and pharmacist if you are allergic to sildenafil, any other medications, or any of the ingredients in sildenafil tablet or suspension.
Ask your pharmacist for a list of the ingredients.
Typical dose: The recommended starting avanafil dosage is 100 mg, but doses can range from 50 mg to 200 mg, depending on your need and response. Viagra, Cialis, vardenafil, and Stendra are considered to work equally well. There isn’t much data that directly compares them against each other. Most existing studies have only looked at how well each medication compares with a placebo (a pill with no medication in it). This means no one can definitively claim that one medication works better than the other for treating ED.
But a systematic review and meta-analysis of a few hundred studies found that Viagra, Cialis, and vardenafil resulted in improved erections in 67% to 89% of people with ED. In comparison, about 30% had improvement with a placebo. All PDE5 inhibitors share common side effects. Most of these are mild and can include: With Viagra, there is a higher risk of vision changes than with Cialis. Among people who take Viagra, 3% get blue vision that lasts a few hours.
On the other hand, Cialis has a slightly higher risk of muscle pain than Viagra and vardenafil. Overall, the immediate side effects of PDE5 inhibitors don’t last very long and aren’t much of a bother. But while the side effects of these medications are similar, the jury is still out on what the risks are of taking these medications long term over several decades. PDE5 inhibitors are generally safe for the heart. But there are two potentially serious side effects to know about: All PDE5 inhibitors can lower your blood pressure. Some medications should not be taken with sildenafil. Make sure you have discussed any other medications you are currently taking or plan to take before starting sildenafil with your doctor and pharmacist. Before starting, stopping, or changing any medications while taking sildenafil, please get the advice of your doctor or pharmacist.

Your doctor will tell you not to take sildenafil if you are taking street drugs containing nitrates. tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, and nutritional supplements you are taking or plan to take.
