Injectable doses do not have to go through the digestive system, therefore, less is needed.
The oral/enteral route is safer and more physiological.
Parenteral administration is any administration that is not via the GI system, meaning oral or rectal. Parenteral means "around the enteral system." Intravenous, subcutaneous, and intramuscular injections are all parenteral routes of administration. While inhalation would be considered parenteral in the strictest sense of the word, inhalation or aerosolization of medications are not usually considered parenteral, nor is topical administration.
For oral Dilaudid (hydromorphone) the equivalent dose would be between 75-80mg's.
Try not to miss a dose, as this increases the risk of pregnancy
Enteral,parenteral,oral inhalation and nasal inhalation are the four common paternal routes by injection.
A suppository is the method used to give a drug through the intestine.
Drugs given orally enter the body by way of traveling through the mouth and into the GI system. Drugs given parenteraly enter through the blood stream (IVs, for example) and act within the body must faster than those given orally. There is a higher risk for infection or complication with parenteral administration than with oral.

The Fentanyl patches by over twice the margin.120mg of oral morphine every 8 hours is equal to 360mg per day of oral morphine (24hr period). The Fentanyl patch equivalent dose (Duragesic for comparison purposes) is a single 100mcg Fentanyl patch.
Most take medications at home and do not have the training nor the equipment to do so. Only drugs designed and intended for administration via a parenteral route should be taken that way. If drugs designed to be taken orally are administered parenterally the "user" could be harmed, and the medication may work very differently than intended. In addition, most drugs are tested as orally administered medications. The way they are absorbed, how they are metabolized, and the dose and time to effect are all designed for oral administration.
The parenteral route of infection occurs when an organism gets access to the tissues underneath the mucous membranes or the skin. Punctures, injections, bites, cuts, wounds, surgery and split skin or mucous membranes (from swelling or dryness) are all examples of parenteral routes of infection. Source: Tortura, Funke, Case.
