Various factors will affect the dose of Darvon-N you are prescribed, such as how you initially respond to Darvon-N and other medications you are taking. This product comes in tablet form and is taken every four hours as needed for pain relief. It is important to not take more than six tablets in a 24-hour period.
An Introduction to Dosing for Darvon-NThe dose of Darvon-N® (propoxyphene napsylate) your healthcare provider recommends will vary, depending on a number of factors, including:
- Other medications you are taking
- How you respond to Darvon-N
- Other medical conditions you may have.
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
Darvon-N Dosage for PainThe standard recommended dose of Darvon-N for treating pain is one tablet (100 mg) every four hours as needed. Do not take more than six tablets in 24 hours.
Each Darvon-N 100 mg tablet contains the same amount of propoxyphene as one 65-mg Darvon® (propoxyphene hydrochloride) capsule, due to differences between the molecular weights of the active ingredients (Darvon-N contains propoxyphene napsylate, while Darvon contains propoxyphene hydrochloride).
If you have been taking Darvon-N on a long-term basis, it is probably best to stop taking it gradually, under the supervision of a healthcare provider. Stopping it too quickly could lead to unpleasant (although rarely dangerous) withdrawal symptoms. Typically, decreasing the dosage by 25 to 50 percent each day works well.
Darvon-N Dosage for Special SituationsIf you are taking certain other medications known as CYP 3A4 inhibitors, you may need a lower Darvon-N dosage. These types of medications can slow the rate at which the liver breaks down (metabolizes) Darvon-N (see Darvon-N Drug Interactions).
If your kidney or liver function is not optimal, your healthcare provider may decide to prescribe a lower amount of Darvon-N. Similarly, lower dosages are often recommended for elderly individuals, who may be more sensitive to the effects of this medication.
