Usual Adult Dose for Chronic Pain:
The following dosing recommendations can only be considered suggested approaches to what is actually a series of clinical decisions over time; each patient should be managed individually.
As First Opioid Analgesic and For Patients who are NOT Opioid Tolerant:
Extended-Release Capsules (Zohydro(R) ER): Initial dose: 10 mg orally every 12 hours
Extended-Release Tablets (Hysingla(R) ER): Initial dose: 20 mg orally every 24 hours
Comments:
-Use of higher starting doses in patients who are not opioid tolerant may cause fatal respiratory depression; monitor patients closely for respiratory depression, especially during the first 24 to 72 hours.
-An opioid tolerant patient is one who has been receiving for 1-week or longer at least: oral morphine 60 mg/day, fentanyl transdermal patch 25 mcg per hour, oral oxycodone 30 mg/day, oral hydromorphone 8 mg/day, oral oxymorphone 25 mg/day, or an equianalgesic dose of another opioid.
 Detailed Hydrocodone dosage information
What happens if I miss a dose?
Since hydrocodone is used for pain, you are not likely to miss a dose. Skip any missed dose if it is almost time for your next dose. Do not use two doses at one time.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. A hydrocodone overdose can be fatal, especially in a child or other person using the medicine without a prescription. Overdose symptoms may include severe drowsiness, pinpoint pupils, slow breathing, or no breathing.
Your doctor may recommend you get naloxone (a medicine to reverse an opioid overdose) and keep it with you at all times. A person caring for you can give the naloxone if you stop breathing or don't wake up. Your caregiver must still get emergency medical help and may need to perform CPR (cardiopulmonary resuscitation) on you while waiting for help to arrive.
Anyone can buy naloxone from a pharmacy or local health department. Make sure any person caring for you knows where you keep naloxone and how to use it.
