Can I Safely Take Alfuzosin ER And Cialis At Different Times Of The Day, Or Should I Use A Lower Daily Dose Of Cialis?

I am currently taking Alfuzosin ER 10mg for BPH. I previously took Cialis 10mg for ED. Can I take both medications safely at different times of the day or do I need a daily dose of lower mg Cialis? I know taking both at the same time can seriously reduce blood pressure.

Hello,

Both medications can lower blood pressure. Taking them together increases the risk of hypotension (low blood pressure). This is especially true when standing up quickly (orthostatic hypotension). Taking these medications at different times of the day (e.g., one in the morning, one at night) may reduce the risk of interacting with each other directly.

However, you should still monitor for any side effects, especially dizziness or light-headedness. Consult your treating doctor, your doctor might recommend a lower daily dose of Cialis (e.g., a lower dose for daily use, typically 2.5–5 mg). This could help minimize the risk of an excessive blood pressure drop when combined with Alfuzosin ER. Consult your treating doctor before making any changes to the prescribed dose.

Take care. Hope I have answered your question. Let me know if I can assist you further.

Regards,
