Voltaren is commonly prescribed for various acute and chronic pain conditions, providing much-needed relief to patients.

The Most Frequently Prescribed Types of Pain Medications for Acute and Chronic Pain Conditions


When it comes to managing acute or chronic pain conditions, there are a variety of pain medications available that can provide relief. Each type of medication works differently to target specific pain receptors in the body, and their effectiveness may vary depending on the individual and the severity of the pain. Below we discuss some of the most frequently prescribed types of pain medications:

1. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)

NSAIDs are a commonly prescribed class of pain medications that help reduce inflammation, relieve pain, and lower fever. They work by inhibiting the production of certain chemicals in the body called prostaglandins, which play a role in pain and inflammation. Some well-known NSAIDs include:

  • Ibuprofen (Advil, Motrin)
  • Naproxen (Aleve)
  • Aspirin

These medications are often used to alleviate pain associated with conditions like arthritis, menstrual cramps, dental pain, and minor injuries. They can be purchased over the counter or prescribed at higher doses for more severe pain.

2. Opioids

Opioids are potent pain relievers that work by binding to opioid receptors in the brain, reducing the perception of pain. They are typically prescribed for moderate to severe pain and are available in various forms, such as tablets, capsules, and patches. Some commonly prescribed opioids include:

  • Oxycodone (OxyContin, Percocet)
  • Hydrocodone (Vicodin, Norco)
  • Morphine

It’s important to note that opioids carry a risk of dependence and addiction, and their long-term use should be carefully monitored by healthcare professionals. They are typically prescribed for short periods or in controlled-release formulations for chronic pain management.

3. Antidepressants

Antidepressants are not only used to treat depression but are also effective in managing certain types of chronic pain. They work by altering the levels of certain chemicals in the brain, such as serotonin and norepinephrine, which can help reduce pain signals. Some commonly prescribed antidepressants for pain relief include:

  • Amitriptyline
  • Duloxetine (Cymbalta)
  • Venlafaxine (Effexor)

These medications are often prescribed for pain conditions like fibromyalgia, neuropathy, and migraines.

4. Acetaminophen

Acetaminophen, commonly known as Tylenol, is a widely used pain reliever that works by raising the pain threshold and reducing fever. It is available over the counter and is often recommended for mild to moderate pain relief, such as headaches and muscle aches. While it is generally considered safe when taken as directed, excessive use can cause liver damage.
