ranitidine + paracetamol ?

Just a quick question. I'm wondering if there are any problems taking paracetamol (for a headache for example) whilst taking ranitidine ?

I'm currently down to a single 150mg tablet of ranitidine a day, and today I'm getting a bit of a headache. Probably the change in weather. Just wondered if the two are safe. "Dr Google" throws up little (even under the American name of acetaminophen) other than some potential interaction stuff shown in animals but nothing proven in humans, but I can't see a clear "yes go ahead" or "don't do it!".

I'm probably worrying far too much (having read the leaflet that comes with it on the side effects!). I'm teetotal at the moment also due to the "don't drink alcohol warning".
