Sildenafil and pills for erectile dysfunction: Viagra and other oral medications
Oral medications are often the first line of treatment for erectile dysfunction. For most men who have trouble keeping an erection firm enough to have sex (erectile dysfunction), these drugs work well and cause few side effects.
Sildenafil (Viagra), vardenafil (Levitra, Staxyn), tadalafil (Cialis), and avanafil (Stendra) are oral medications that reverse erectile dysfunction by enhancing the effects of nitric oxide, a natural chemical your body produces that relaxes your muscles. of the penis. This increases blood flow and allows an erection to be achieved in response to sexual stimulation.
How Oral Medications Are Different
Although they work in a similar way, each oral medication has a slightly different chemical makeup. These minor differences affect the way each medication works, such as how quickly it works and goes away, and possible side effects. Your doctor will consider these factors, as well as other conditions you have and possible interactions with other medications you take.
Sildenafil (Viagra). This medicine is most effective when taken on an empty stomach one hour before sexual intercourse. It is effective for four to five hours or longer if you have mild to moderate erectile dysfunction.
Vardenafil (Levitra, Staxyn). This medicine is also most effective when taken one hour before sexual intercourse and can be taken with or without food. A high-fat meal may prevent it from being absorbed quickly.
Vardenafil is effective for four to five hours or longer if you have mild to moderate erectile dysfunction. A newer form of the drug that dissolves on the tongue may work faster than the pill you swallow.
Tadalafil (Cialis). This medicine is taken with or without food about an hour or two before sexual intercourse. It is effective for up to 36 hours. It can be taken in a small daily dose or in a larger dose as needed.
Avanafil (Stendra). This medicine is taken with or without food 30 minutes before sexual intercourse, depending on the dose. Lasts up to six hours.
Because these drugs are similar in efficacy, the American College of Physicians recommends that the choice be based on your preferences, including cost, ease of use, how long the drug's effects last, and side effects. There are generic versions of sildenafil, vardenafil, and tadalafil available.
When oral medications may not be safe
Before taking any erectile dysfunction medication, first, ask for your doctor's approval. Erectile dysfunction medications may not work or be dangerous if:
You take nitrates, commonly prescribed for chest pain (angina), such as nitroglycerin (Nitro-Dur, Nitrostat, others), isosorbide mononitrate (Monoket), and isosorbide dinitrate (Dilatrate-SR, Isordil)
You have very low blood pressure (hypotension) or uncontrolled high blood pressure (hypertension)
You have severe liver disease
You have kidney disease that requires dialysis
Side effects
Most men who take oral erectile dysfunction medications are not affected by side effects. When side effects do occur, they may include the following:
Redness
Headache
Indigestion
Visual changes, such as blue tint to vision, sensitivity to light, or blurred vision
Runny or runny nose
Back pain
Rarely, more serious side effects can occur, including the following:
Hearing loss or vision loss. Some men have had sudden hearing loss or vision loss after taking one of these medications. However, it is not clear whether the vision or hearing loss was caused directly by the drug or by a pre-existing condition. If you are taking an oral medication for erectile dysfunction and you have a sudden loss of hearing or vision, seek immediate medical attention.
An erection that does not go away on its own. Called priapism, this rare condition can be painful and requires medical treatment to prevent damage to the penis. If you have an erection that lasts longer than four hours, seek immediate medical attention.
Buying Oral Erectile Dysfunction Medications Online
Erectile dysfunction treatments are big business, and online scams abound. If you buy medicines online:
Verify that an online pharmacy is legitimate. Never order medication from an online pharmacy if there is no way to contact the pharmacy by phone, if the prices seem too good to be true, or if they tell you that a prescription is not necessary. Some illegal businesses sell counterfeit versions of legitimate drugs, which may be ineffective or dangerous. In the United States, the National Association of Boards of Pharmacy can tell you if an online pharmacy is licensed and up-to-date with its obligations.
Make sure you get the correct dosage and recipe. When ordering medications, and when you receive them in the mail, make sure they are the exact dose and type prescribed by your doctor.
Don't be fooled into buying "herbal viagra" and never take any medication that claims to be "herbal" or over-the-counter equivalent to an oral erectile dysfunction medication. These are not an effective alternative, and some contain harmful substances. https://www.123kamagraaustralia.com/kamagra-100-oral-jelly/
