Following your initial experience with the 50-mg dose, it's advisable to communicate with your healthcare provider about how your body reacted to the medication. This feedback should include whether you noticed an improvement in erectile function or if you experienced any adverse reactions.

This section will provide answers to some frequently asked questions about Viagra usage and its dosing.

What is the recommended starting dosage for Viagra?

The common initial dosage prescribed for Viagra is 50 mg. However, based on individual health considerations, your doctor may opt for a lower starting dose of 25 mg. It is important to adhere to your doctor's specific instructions regarding dosing.

A 25-mg starting dosage may also be considered if you are 65 years of age or older. For more details regarding dosage adjustments, refer to the section above.

Is the dosage of Viagra determined by body weight?

No, Viagra's dosage is not dependent on a person's weight. The prescribing physician determines the appropriate dosage based on age, liver and kidney function, as well as the effectiveness of the drug for treating your erectile dysfunction.

Does a patient's age influence their Viagra dosage, such as comparing a 70-year-old to a 30-year-old?

Yes, age is a significant factor in determining the right dosage of Viagra for an individual.

As people age, their bodily systems, including the heart, liver, and kidneys, may not function as efficiently as they once did. This sometimes results in a delayed elimination of drugs from the body, raising the risk of side effects for older adults.

If you are 65 years or older, your doctor may suggest commencing treatment with a lower dosage of Viagra. Typically, a 70-year-old may be started on a dosage of 25 mg, while a 30-year-old in good health may be prescribed the standard starting dosage of 50 mg.

Regardless of age, you should always take the prescribed amount approximately one hour before engaging in sexual activity.

If your current Viagra dosage provides satisfactory results without troublesome side effects, it is likely that you will continue on that regimen. If a prescribed dosage is effective but leads to bothersome side effects, your healthcare provider may adjust the dosage downward. Conversely, if the current dosage does not effectively aid in obtaining or maintaining an erection, an increase may be necessary.

What are the potential consequences of taking a higher dosage of Viagra than prescribed — for instance, 150 mg or 200 mg?

It is crucial to adhere strictly to the dosage your healthcare provider prescribes. The maximum advised daily dosage of Viagra is 100 mg. Taking higher quantities can elevate the risk of severe side effects, which may include:

The prescribed dosage of Viagra will depend on several individual factors, including:

Viagra is intended for oral use and should be taken approximately one hour prior to sexual activity. The tablet should be swallowed whole for optimal absorption.

It's important to remember that Viagra is utilized solely when needed, about one hour before engaging in sexual activity. Continuous daily intake is not required for the medication to maintain efficacy.

If you happen to forget to take Viagra at the one-hour mark before sexual activity, you can take it as soon as you recall. The effects can begin as soon as 30 minutes after ingestion and typically last around four hours.

If you are concerned about forgetting to take your dose of Viagra, consider setting a reminder alarm on your phone or using a mobile application for notifications. Alternatively, you might ask your partner to gently remind you to take your medication about an hour before sexual intercourse.

It is imperative not to exceed the dosage prescribed by your healthcare provider, as overuse can lead to significant health issues.
