Applies to: amlodipine, Norco (acetaminophen / hydrocodone)

AmLODIPine and HYDROcodone may have additive effects in lowering your blood pressure. You may experience headache, dizziness, lightheadedness, fainting, and/or changes in pulse or heart rate. These side effects are most likely to be seen at the beginning of treatment, following a dose increase, or when treatment is restarted after an interruption. Let your doctor know if you develop these symptoms and they do not go away after a few days or they become troublesome. Avoid driving or operating hazardous machinery until you know how the medications affect you, and use caution when getting up from a sitting or lying position. 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.

With regards to the time you should take them and how far apart you must take them, as both are prescription medications only, the Dr. who prescribed these drugs must have told you about the potential risk of an interaction and given you instructions and guidance on how far apart to take them ort to take them together. It is your DR. who is responsible for your treatment and safety. This is a delicate matter as you can read from the interaction report it can affect your organism in serious ways and the responsibility as I mentioned before for your treatment is the Dr. who prescribed these prescription medications only.
Perhaps someone else will answer your question or not and probably say they take this combination and nothing happens to them, that it is safe, well, remember everyone reacts differently to medications, benefits, potential risks, possible side effects and interactions.

Contact your Dr. and clarify your doubts with the person who is responsible for your treatment and safety.
