Viagra Dosage Instructions. Viagra 100 mg Dosing Information

Viagra, which is generically known as sildenafil citrate, is used to treat impotence (erectile dysfunction) and a typical Viagra dosage varies between 50mg and 200mg. It belongs to a group of medicines known as PDE5 inhibitors (relatives of the drug include Levitra and Cialis). Generic Viagra can be purchased online for less than a dollar per tablet. Viagra is also suitable for the treatment of premature ejaculation.

Important Information About Viagra

Viagra generally starts working between 15 minutes and two hours after oral administration. It is therefore recommended that Viagra is taken at least an hour before engaging in sexual activity. Viagra dosage will vary from patient to patient, although as a starting point men are recommended to opt for 50-100mg dependent on size, weight and other factors – for example, if the patient is currently taking medication which reacts with the drug, a smaller Viagra dosage may be required.

Like other medications, some users experience side effects when taking Viagra. Some of the more common side effects include nausea (feeling sick) and facial flushing. In extremely rare cases, users have reported the following side effects: photosensitivity (feeling uncomfortably sensitive to light), abnormal/blurry vision, pain in the abdomen, low blood pressure (hypotension), abnormal heart rhythm (tachycardia), joint pain (arthralgia), itching, muscle pain (myalgia), painful eyes and/or a rash. Another extremely rare but potentially serious effect of Viagra is heart attack, although these cases have been too sporadic to even collate data on.

Viagra Dosage Instructions

Pharmacists recommend that most patients start with a Viagra dosage of 50mg, administered orally, as and when required. Viagra should be consumed approximately one hour before sex. As a general rule of thumb, the 50mg Viagra dosage is a guideline for first-time users, and can be increased to 100mg if required or decreased to 25mg, depending on the efficacy of the drug on the individual. Viagra can be taken with food or on an empty stomach, however fatty foods may decrease its effects. Users with moderate hepatic impairment (liver or kidney problems) should take a Viagra dosage of no more than 25mg. Patients on dialysis should completely avoid Viagra and other erectile dysfunction medications.

Usual Geriatric Viagra Dose For Erectile Dysfunction

Viagra dosage adjustments are not required based on age, although a total standard dose of 100mg can be carefully considered, based on the user’s tolerance and reaction to the medicine. It is recommended that first-time users over the age of 65 should consider a lower starting dose (25-50mg) to minimise the potential of any unwanted side effects. Users should not exceed a Viagra dosage of 100mg in 24 hours, as this increases the propensity of uncomfortable side effects, including priapism. Effective Viagra dosage will vary from person to person – for a more accurate dosage suggestion, based on your circumstances, it is advisable to visit a doctor or a qualified pharmaceutical specialist.

Viagra Dosage Guidelines

Viagra Dosage Varies 25 50 100 Standard 150 200 mg

Generic Viagra is typically available as a 25mg, 50mg, 100mg, 150mg or 200mg pill. The recommended beginners dosage for adults is 50mg to 100mg, based on personal circumstances and overall health. No evidence currently exists to suggest the elderly are more susceptible to side effects, therefore it is safe for those over 65 to take the same dose prescribed to younger males. Certain pre-existing conditions (liver problems, for example) may cause unwanted side effects. In this instance, you should speak to a certified medical professional before self-administering Viagra.

Viagra 100 mg Dosing Information

Viagra is absorbed reasonably quickly by the body after oral administration. Effects can be witnessed as early as 15 minutes after taking a 100mg dose. Most patients reach the peak state of the medication half an hour to two hours after an oral dose of 100mg. Viagra is typically processed by the body after six hours. Studies suggest that up to one-third of patients between the ages of 18 and 89 will continue to use Viagra after initially trialling it. Viagra is not addictive and needs only to be taken as and when required.

What Happens If I Overdose?

If you believe you may have overdosed on Viagra, it is important that you seek medical assistance from a qualified professional. If serious symptoms (such as loss of consciousness) arise, you should seek emergency help from the nearest hospital or call emergency services immediately.

Although the effects of Viagra typically last between four and six hours, administering multiple doses within a 24 hour time period can increase the likelihood of accidental overdose. Pre-existing medical conditions (such as kidney impairment or liver disease) can increase the potential for overdose. Certain heart medications, such as nitrites, can affect the performance of the drug.

Symptoms can vary depending on the level of Viagra over-dosage, and can include headaches, a flushed face, ocular pain and changes in vision, muscular pain (particularly in the lower back), swelling of the lower extremities and painful erections (priapism).

Should you experience severe side effects when taking Viagra, you should discontinue use and seek the advice of a pharmacist or doctor before attempting to use the medicine again. In order to avoid an overdose, you should always stick to recommended dosage guidelines (up to 100mg in a 24 hour period).

What Happens If I Miss A Dose?

Perhaps the greatest advantage of Viagra is that you only need to take a pill as and when you require. You don’t need to take it like you would with a preventative medication – simply administer a pill an hour before engaging in sex (Viagra is fast acting and can get to work within 15 minutes). Since Viagra is taken only when you need it, it is not possible to miss a dose, although you may find that sexual performance is more difficult without it. Viagra is non-addictive and building up a tolerance to the drug is unlikely.

What Should I Avoid While Taking Viagra?

When taking Viagra, you should avoid eating grapefruit or drinking grapefruit juice, although alternative citrus fruits are safe to consume. Certain enzymes within grapefruit decrease the ability of the body to process PDE5 inhibitors such as Viagra, Cialis and Levitra. Although moderate amounts of alcohol are safe to take with Viagra, larger quantities should be avoided, as this can result in low blood pressure or fainting.

Some medications used in the treatment of blood pressure, seizures and depression should not be combined with Viagra – side effects can be increased as a result. For peace of mind, you should discuss any concerns with a qualified professional before taking Viagra.

Viagra Alternative Uses

Although primarily used to treat erection problems, Viagra has a host of alternative uses with some researchers remarking that it could in fact be as versatile as aspirin. Here are just a short selection of alternative uses for Viagra:

Stroke

Studies suggest that if stroke patients are administered Viagra within three days of the condition striking, it could help both men and women to regain movement, improve speech and cognitive function via the effects it has on the cGMP molecule, which is believed to create new cells in the brain.

Jet lag

Believe it or not, Viagra’s effect on certain brain enzymes may help speed up recovery times from jetlag.

Multiple sclerosis

Viagra may help alleviate symptoms of MS, and can protect against the degeneration of certain brain cells.
