What types of infections is this antibiotic used for? How long & at what dosages per day does one take it? And, is it in any way related to penicilin-based antibiotic drugs?

Cephalexin is a cephalosporin antibiotic used to treat certain infections caused by bacteria such as pneumonia and bone, ear, skin, and urinary tract infections. Antibiotics will not work for colds, flu, or other viral infections.

The dosage guidelines for this medication state the following:

It is usually taken every 6 hours (four times a day) or every 12 hours (twice a day) for 7-10 days. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand.

Cephalexin usually comes in doses of 500mg capsules (as it did for me in the past); but it could be different for your prescription, so you'd have to ask your pharmacist or doctor what dose you are getting.

To answer your last question; Cephalexin belongs to a class of antibiotics called cephalosporins. They are similar to penicillin in action and side effects (and in some cases can be substituted for penicillin). But it is not related to penicillin. If you are allergic to penicillin, you might be given Cephalexin as a replacement.

I am a quadriplegic and have frequent urinary tract infections for which my physician prescribes antibiotics. However, I like to have some on hand in case an infection starts at the end of the week or over the weekend and when I travel. When we cruise to Mexico, we can purchase antibiotics without a prescription but I noticed this last bottle, Ayporine/Cefalexina has an extremely bad odor. Is this normal or is this a bad batch?
