The effect of Viagra can vary from person to person and can be subject to several factors such as age, general health and diet. Although its effects typically last around 4 hours, Viagra hits its peak after 1 to 2 hours. This is why it is recommended that you take Viagra approximately 60 minutes before sexual activity.
Viagra should start to show its effects 30 minutes after consumption although, this can vary from person to person. Additionally, when taking Viagra, sexual stimulation is usually required to achieve an erection. When you first start taking Viagra, you may need to try the medication, as directed, up to 4 times before you experience the desired results.
The standard recommendation is that Viagra should be consumed an hour before sexual activity at a starting dose of 50mg. However, the tablet can be taken as early as four hours before, and as late as 30 minutes before sexual interaction. The dose can vary or be adjusted between 25 to 100mg based on individual response and potential side effect. If a dose of 50mg is not effective, increasing the dose to 100mg is an option. If a 50mg dose is effective but causes side effects, a decrese to 25mg can be considered. Viagra should not be taken more than once in a 24 hour period. If you do not respond well to Viagra, regardless of dose, alternative medications are available. These include Cilais, Levitra and Stendra.
The dosage and effects of Viagra can vary from person to person. Factors which may influence the effectiveness and duration of action of Viagra include:
Drug Interactions: Viagra can interact with different medications, leading to decreased effectivity and potentailly serious side effects.
Health: Viagra is not recommended for men suffering from liver or kidney problems. Impaired liver or kidney function can affect metabolism and elimination of Viagra. This can in turn lead a higher rate of serious side effects.
Alcohol: Consumption of more than 2-3 units of alcohol can alter the effects of Viagra. Alcohol impairs the nervous system and can worsen erectle dysfunction and reduce the time in which Viagra remains effective. It is also worth noting that both Viagra and alcohol can lower blood pressure. This increases the likelihood of related side effects such as lightheadedness, dizziness and even, fainting.
Diet: Taking Viagra with a heavy meal, high in proteins and fats, can delay the effects of Viagra, as your body will prioritise digesting the food. Therefore, taking Viagra on an empty stomach can both speed up and enhance results.
Age: Viagra is likely to last longer in men over age 65 due to a naturally slower metabolism. Prolonged effects and an increased risk of side effects may result. If you are over 65, consider starting with a lower dose of Viagra.
