$wpdb query takes effect only on the next request

I have a problem using $wpdb->query.
I have a piece of code similar to this:

$meta_value = get_user_meta($user_id, 'mbids_standard_points');
$wpdb->query("UPDATE wp_usermeta SET meta_value = meta_value + '1' WHERE meta_key='mbids_standard_points'");
$updated_value = get_user_meta($user_id, 'mbids_standard_points');

The problem is that $updated_value doesn’t change after the query. But does change on the next page reload. Is there a mistake in this code?

UPD: I figured out that WP caches usermeata. Is there a way to purge it?
