Normal Dose of Viagra

The suggested dosage for people 18 to 64 years old is 50 mg. People over 65 frequently begin with a lesser dose of 25 mg.

Depending on its efficacy and how well it is tolerated, the dose may be raised to 100 mg.

Does age impact the dosage of Viagra?

If age impacts Viagra dosage, what is the Viagra dosage for a 30-year-old compared to a 70-year-old?

An appropriate Viagra dosage for a 70-year-old is different from 30 year old.

People’s hearts, livers, and kidneys lose some of their former functions as they age.


Due to this, an older adult’s body may process medications more slowly than an adult their age. 

Drugs, therefore, linger in the body for a longer period, increasing the possibility of negative effects.

Your doctor might prescribe you less Viagra if you’re 65 or older. 

For a 70-year-old, 25 mg of Viagra would typically be the recommended starting dose. 

The typical beginning dose for a 30-year-old without any additional health issues is 50 mg.

You can roughly take it an hour before sex.

You’ll probably keep taking Viagra if the recommended dosage is effective and has no unfavorable side effects. 

Your doctor might boost your dosage if it doesn’t help you achieve or keep an erection.

Last Word

The doctor recommends the right Viagra dosage. They might analyze multiple health-related factors and recommend the correct dosage.

Viagra dosage is usually available in three strengths, i.e., 25 mg, 50 mg, and 100 mg. However, generic Viagra is available in a greater variety of strengths.

Viagra is usually a safe and well-tolerated medication for people young as well as elderly men.

But, an ED patient should never self-medicate and take the tablet according to the doctor’s recommendation.
