Older adults (65 years and older) often require lower dosages due to decreased liver and kidney function, affecting drug metabolism and excretion. A starting dose of 25 mg is frequently recommended for this population.
Individuals with severe liver impairment may need significant dosage reductions or alternative treatments, as the liver plays a crucial role in Viagra’s processing. Consult your doctor for personalized guidance based on your specific liver function tests.
Kidney problems also influence Viagra’s elimination from the body. Reduced kidney function necessitates careful dosage adjustments or the selection of alternative medications, as drug accumulation can lead to adverse effects. Your physician will assess your creatinine clearance to determine the appropriate dose.
Certain heart conditions, such as unstable angina or recent heart attack, often necessitate caution and possibly contraindicate Viagra use. Always inform your doctor of your complete medical history, including any cardiovascular issues.
Patients with low blood pressure should use caution. Viagra can further lower blood pressure, potentially causing dizziness or fainting. Your doctor will assess your suitability for Viagra based on your blood pressure readings.
If you take medications for heart conditions (nitrates), you absolutely must not take Viagra. This combination can cause a dangerous drop in blood pressure. Always disclose all medications you are taking to your physician before starting any new treatment.
Always discuss your complete medical history, including all medications and supplements, with your physician before taking Viagra to ensure safe and effective treatment. They will personalize the dosage based on your unique circumstances. Never adjust your dosage without consulting your doctor.
