Viagra is a drug that helps men have an erection during sexual intercourse. It works by increasing blood flow to your penis and inhibiting the breakdown of a substance called cGMP.
It only works if there is stimulation during sexual intercourse, such as when you orgasm. This means it won’t help you keep an erection after ejaculation (the refractory period).
How long does it take to work?
It takes about 30 minutes for Viagra to start working, but it can take longer if you have certain health conditions or if you are taking other drugs or alcohol. For this reason, it is important to plan in advance when you want to have sexual intercourse and take a pill an hour before you intend to have sex.
The active ingredient in Viagra is sildenafil, and it works by increasing blood flow to your penis. This helps your body produce harder erections and lasts longer.
When your penis is stimulated, it releases a substance called nitric oxide. The nitric oxide is converted into a chemical called cGMP, which makes smooth muscle relaxation and allows more blood to flow into your penis. This is why the erections you get when using Viagra last longer and are harder to break down.
Once you have taken a pill, the amount of nitric oxide in your blood decreases as the drug is broken down by your liver. However, it’s still in your blood and can continue to work for up to four hours after you have taken it, depending on the dose you took which is available at apothekepunkt.
Viagra comes in 25, 50 and 100 mg doses, with a higher dose allowing for a longer lasting effect. You should talk to your doctor about what dose is right for you, as this may vary from one person to the next.
You should always follow your doctor’s instructions when taking any drug, including Viagra. Overdosing can cause priapism (a painful, constant erection that lasts more than 4 hours), so it is essential to follow the dosage you have been prescribed by your doctor.
If you are taking a high dose, it is best to take it on an empty stomach and in a relaxed state of mind. This is because your body will need time to digest the medication before it can be effective.
It’s also a good idea to avoid drinking alcohol and eating food before you take a pill, as this can affect how quickly it is absorbed into your system. This is especially true if you are on the highest dose of Viagra.
How long does it last?
One of the biggest questions men have after taking Viagra is how long it will last. This is understandable, as it can take some time for the drug to work.
But how long does it last depends on a few different things, including your age, diet, and overall health. You also have to think about other medications you might be taking or supplements you are taking.
Older people, for instance, might have a longer time to eliminate the medicine from their bodies than younger men, so it can be in their system longer. Likewise, if you have certain medical conditions like liver or kidney disease, you may have a longer time to eliminate the drug from your body.
For most men, the medication will start to work around an hour after you take it. This is because it takes time for it to absorb into your bloodstream.
Once it does, the drug will typically have an effect on your erections for 4 or 5 hours. It’s important that you don’t experience an erection that lasts more than four hours – this is called priapism and requires emergency treatment.
It will also help to ensure that you don’t have alcohol in your system while you are taking it. This can make the effects of the drug less effective, as it will decrease blood flow to the penis.
You should take the medication an hour before you plan to engage in sexual activity. This way, you can give it a chance to work before you get into bed.
The effects of the medication will wear off a little bit each hour, so it’s a good idea to keep an eye on how long you are going to be in bed. This is so that you can decide whether to take another dose of the medication or wait it out until you have finished sex.
Some men report that they can still feel the effects of Viagra for quite a while after they have finished sex. This is because the drug has an effect on your brain and psyche, so it might stay in your system for a bit longer than other ED medications.
Can you buy it online?
Getting a prescription from your doctor is the safest way to buy Viagra online. You can also purchase it from some telehealth companies and online pharmacies. However, you should be cautious about buying from these websites because they may be fraudulent. A 2012 study found that 77% of the samples they looked at from online Viagra websites were counterfeit.
Viagra is a common medication for erectile dysfunction (ED). It is often used to treat this condition because it works by increasing blood flow to the penis. The drug is derived from the chemical nitric oxide, which increases the pressure in the blood vessels and causes them to dilate.
When you take the pill, it can start working within 30 minutes and last up to four hours. But, it is important to understand that the exact peak time for this medication can vary from man to man.
You should start taking the pills an hour before sexual activity. This will give you time to get an erection and keep it strong. It is also important to drink plenty of water and eat healthy foods.
It is possible for you to buy Viagra online without a prescription from some telehealth companies and online pharmacies, but it is not recommended. One reason for this is that these companies often sell fake Viagra pills.
Another reason is that Viagra can be dangerous if taken improperly. The drug can cause serious side effects, including heart problems and stroke. It can also cause a decrease in testosterone, which is a male hormone that helps build muscle.
If you are experiencing ED, it is a good idea to seek treatment from your doctor as soon as possible. There are several different medications that can help with erectile dysfunction, and the one that works best for you depends on the cause of your problem.
The most effective erectile dysfunction medication is Viagra. This is because it increases the blood flow to the penis and can increase the size of the veins in your penis. It is also effective for helping you to maintain an erection once it has been achieved.
Can it help you keep an erection after ejaculation?
If you have erectile dysfunction (ED), your doctor may prescribe Viagra or another medication to help you get and keep an erection. These drugs are called PDE5 inhibitors and are approved by the Food and Drug Administration to treat ED in men 18 years and older.
Viagra is a prescription medicine that works by relaxing the muscles in blood vessel walls to increase blood flow to the penis and make it easier to achieve an erection. It’s available in tablet form, which you take an hour before sexual intercourse. The dose you’re prescribed will vary by doctor.
For best results, you should not drink alcohol or eat any fatty foods before taking this medication, as this can reduce its effectiveness. You should also not take more than the prescribed dose.
It’s important to remember that erectile dysfunction can have many causes, including physical and psychological issues. If you have any underlying medical conditions, talk to your doctor about alternative medications.
Medications like Viagra and Cialis are primarily used to treat erectile dysfunction, or impotence. They’re usually given for a short time to treat this condition, while you get any underlying health problems under control.
Some men use over-the-counter (OTC) products to help get an erection instead of a prescription medicine. These OTC products are made with a similar ingredient to the ones found in Viagra, and they can be more affordable.
However, these OTC products can have side effects, so you should discuss them with your doctor before using them. Other OTC treatments include vasodilators, vacuum pumps, and creams that contain alprostadil.
The most common side effect of these medicines is priapism, which happens when the penis stops being hard after you have orgasm or are in a refractory period. This can be uncomfortable, but you should not let it stop you from enjoying your sex experience.
If you want to have more sex, ask your doctor about getting an external medical device, which can be placed in the urethra to help get an erection. These devices are typically used with the help of an urologist, or a doctor who specializes in treating urological issues.
