There are some painkillers that can be taken by injection, either intramuscularly (IM) or intravenously (IV). These drugs can also be taken by infusion over a period of time. The pain medication injection list may contain non-opioid OTC painkillers or prescribed opioids. Some patients are advised to take intravenous pain medications, such as acetaminophen and non-steroidal anti-inflammatory drugs for immediately relieving severe pain after an accident. On the other hand, IM pain meds are taken for relieving mild and moderate pain. Some injectable pain meds, such as opioids, are taken intravenously at regular intervals for relieving pain after surgery, as the patient may still be under the influence of anesthesia and cannot take painkiller pills or capsules orally. Also, taking IV painkillers after labor is common, but should be used as prescribed.

The main advantage of taking IV medication is that it gives its effect rapidly after a few minutes of administration.

Liquid pain medications are completely absorbed in about 15 to 30 minutes after taking it. So, it gives its effect more rapidly than tablets and capsules. The oral pain meds cannot be taken after surgery as the patient cannot take any medication orally and also not taken while the patient is vomiting.

Buccal And Sublingual Pain Medications

Sublingual pain meds are taken under the tongue without swallowing to dissolve and diffuse the medication into the blood, while buccal painkillers are taken between the gums and cheek and also absorbed directly into the blood. One of the major advantages of taking sublingual pain medication is that it is absorbed rapidly and gives its effect faster than oral painkiller pills. Sublingual pain meds are not subject to the hepatic first-pass metabolism, so it is completely absorbed into the blood. The effect is achieved after 15 minutes of taking sublingual painkillers. Therefore, using short-acting sublingual painkillers such as fentanyl sublingual pills is preferred for rapid relief of severe pain. However, using these types may irritate the mouth while taking it with a patient has mouth sores or lesions.

Only a medical specialist can determine the type of pain correctly and prescribe the right medication, which won’t cause the side effects. Don’t self-medicate as it may cause significant harm for the body.

This type of painkillers is completely absorbed into the blood over a long period of time. Transdermal pain medications usually contain opioids such as fentanyl and buprenorphine. This type of medication is used for relieving chronic pain.

It is not recommended to expose the pain medication patch to any source of heat such hot water as the extreme heat could increase its blood absorption and may cause severe adverse reactions. Some patients cannot tolerate the patch because it may cause skin irritation.

The patient shouldn’t take alcohol when using patches, as using painkillers with alcohol may increase the risk of side effects such as nausea and drowsiness. Mild withdrawal symptoms may appear in the newborn baby whose mother takes painkiller patches during pregnancy.

Pain Pumps

The painkillers may be administered directly to the site of pain using an implanted pump. This pump is inserted under the skin in the abdomen to continuously deliver small quantities of the medication at a constant rate for a long period of time. The pump can be periodically refilled with the medication every 1 to 3 months. It is used to treat chronic pain that cannot be relieved by oral meds or surgery. Moreover, pain pump medication is used when the patient cannot swallow. The pump works more efficiently than oral pills or capsules because it delivers the drug directly into the spinal fluid, and not a subject for the first-pass metabolism of the liver. On the other hand, the pump may cause serious complications such as infection, leakage of spinal fluid, and moving the pump within the body. The painkiller overdose symptoms may occur as a result of these complications.

Topical Pain Relievers

Topical painkillers are applied directly to the skin for temporarily relieving chronic pain. They can be available as creams, gels, and rubs. Most topical forms are available over the counter such as a natural painkillers and some require a doctor’s prescription. The topical pain relievers are suitable for patients who have difficulty swallowing or who cannot tolerate the injectable route. The topical form rarely produces side effects as oral pills and liquids. Topical creams and gels have several advantages over oral pills; it has less systemic side effects, not undergoing first pass-metabolism, and target pain site only with low doses of the drug. However, these forms may increase the risk of skin swelling and irritation.

Suppository Pain Medications

There are some NSAIDs and opioids that can be taken intranasally. The nasal pain medication is rapidly absorbed through the nasal capillary network and delivered to the blood. It can be used in patients with a history of chronic pain in lower doses. The intranasal route is painless, noninvasive, with a rapid onset of action. It bypasses the first-pass metabolism with higher bioavailability. It has mild side effects with a lower risk of overdose. The nasal spray pain medications may cause local side effects with short term use such as nasal irritation and irreversible damage of nasal cilia. Some intranasal opioids such as fentanyl may cause systemic side effects. However, respiratory depression does not occur with nasal painkillers.

The long term use of intranasal opioids may cause epistaxis, sinus congestion, and pharyngitis.

Gas And Air

It is the common method for relieving labor pain without side effects on the baby. Gas and air do not completely relieve pain, but it can rapidly reduce it. It is used efficiently, and its effects wear off once stop gas breathing. Drowsiness, nausea, and mild headache are the expected side effects of gas painkiller.

How Painkillers Are Abused

Many people use pain medications for non-medical purposes. Except abusing the common pills by extending the prescribed dosage, recreational users smoke and snort opioid pain medications. Ways of taking analgesics listed below are dangerous and may cause lung and mucosal damage, and many other adverse effects, as well as lead to addiction development and overdose.

Smoking Painkillers

Some abusers smoke painkillers to get high, by heating the substance. The effect of opioids starts after about 10 to 15 minutes of inhaling it. This route of taking painkillers has no therapeutic indication. Smoking painkillers can be as dangerous as the injectable route. The chronic use of smoking opioids can cause respiratory depression and chronic coughing.

The repeated use of painkillers in such way causes the addiction, dependence, and tolerance very soon. The risk of opioids overdose is also too high.

Snorting Painkillers

There is another route of taking painkillers is by snorting it. The abusers crush the tablet into a powder to snort it. While snorting painkillers, the medication is rapidly absorbed through the nasal membrane and then goes directly into the blood circulation without undergoing hepatic metabolism.

Snorting pain meds not only has side effects but also increases the chance of addiction. The repeated snorting of these drugs may cause damage to nasal passages, nasal mucosa irritation and sinusitis.

Snorting opioids can cause a sudden decrease in blood pressure, respiratory depression, and cardiac arrest. Some opioids, such as hydrocodone can lead to hypersensitivity pneumonitis when snorting it.
