Cenforce 100 is typically taken as needed for erectile dysfunction, so there is usually no regular dosing schedule. If you miss a dose in the context of prescribed regular use (such as for pulmonary hypertension, though this is uncommon), take it as soon as you remember. However, if it's almost time for the next dose, skip the missed one—never double up to make up for it. For erectile dysfunction, simply take the dose when required, about 30–60 minutes before sexual activity. Always follow your doctor’s instructions, and avoid taking multiple doses in a 24-hour period, as this can increase the risk of side effects like dizziness, vision changes, or priapism (prolonged erection).
