Your doctor determines the best Viagra dosage based on your individual needs. Generally, 50mg is the starting point for most men, but this can vary significantly. Older men, those with liver or kidney problems, or those taking certain medications might need a lower dose (25mg) to avoid side effects. Conversely, if 50mg proves ineffective, your doctor may increase it to 100mg. However, exceeding 100mg isn’t recommended due to increased risk of side effects.
Age and Health Conditions
Age significantly influences Viagra’s metabolism. As we age, our bodies process medications more slowly, increasing the risk of side effects at higher doses. Pre-existing heart conditions, low blood pressure, or severe liver or kidney disease require careful consideration and often a lower starting dose. Always disclose your complete medical history to your physician before starting any medication.
Medication Interactions
Certain medications can interact negatively with Viagra, increasing the risk of side effects or reducing its effectiveness. Nitrates, often prescribed for chest pain, are a particularly dangerous interaction. Other medications that may interact include alpha-blockers (used to treat high blood pressure and enlarged prostate), some antifungals, and certain HIV medications. Always provide your doctor with a complete list of all medications, supplements, and herbal remedies you are currently taking.
