I am a little confused on your description. I am not finding a pill with those markings that is also scored on both sides. This is the one I did find:

Same markings without any score marks.
If this is what you have, then you have:
Hydroxyzine Hydrochloride Tablets 25mg
HYDROXYZINE (Vistaril®) is an antihistamine. This drug relieves itching and allergic skin reactions; may relieve emotional conditions that result in anxiety and tension; reduces nausea and vomiting; helps make you sleep before surgery or at bedtime, and may help with pain relief after surgery.
