Drug Interactions between Cascor and cephalexin

Ask your doctor before using doxazosin together with ethanol (alcohol). Using doxazosin with ethanol (alcohol) can lower your blood pressure. This can cause dizziness or feeling like you might pass out, especially when getting up from a sitting or lying position. This may be more likely to occur when you first start taking either of these medications. You may need a dose adjustment or need your blood pressure checked more often if you take both medications. You may develop flushing, warmth or redness under your skin or tingly feeling after alcohol intake (especially in you are of Asian descent) and should be advised to avoid alcohol or limit your intake. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Cephalexin and multivitamin with minerals should not be taken orally at the same time. Products that contain zinc may interfere with the absorption of cephalexin into the bloodstream and reduce its effectiveness. You should take multivitamin with minerals at least three hours after taking cephalexin. Talk to a healthcare professional if you are not sure whether a product contains something that could potentially interact with your medication or if you have questions on how to take this or other medications you are prescribed. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
