Every one of us has used a painkiller at some point in our lives. Different types of painkillers can be used to relieve acute (short-term), and chronic (long-term) pains. Acute pain can be sudden, but it will resolve once the root cause has been addressed. Chronic pain, on the other hand, can last for many months and increase the dependence on painkillers over time. Although painkillers are considered safe, excessive or prolonged use can have adverse effects on health.
What is the mechanism of painkillers?
The human body has hundreds of nerves that help to transmit messages from one part of the body to another. Although nerves can be found all over the body, their endings (nerve endings), are located in the skin, gastrointestinal tract, and connective tissue. Prostaglandins are chemicals that activate nerve endings when cells in the body become injured. This triggers the release of prostaglandins which send signals to the brain, describing the injury or pain.
- Two ways painkillers, also known medically as analgesics can be used are:
- To ensure that your brain does not receive pain signals, prevent the release of prostaglandins.
Stop the transmission of messages between nerves so that pain signals do not reach the brain.
These mechanisms allow painkillers to temporarily reduce or relieve the pain.
What are the most common painkiller medication types?
Painkillers are broadly divided into two categories:
Non-prescription (over-the-counter)
Prescription painkillers.
- Non-prescription painkillers (Non-prescription): These painkillers, such as paracetamol or acetaminophen, can be purchased without a prescription and are safe to use. These painkillers are used for body aches and headaches.
- Prescription painkillers are: Opioids and steroids, which are strong analgesics, are prescribed to people who are experiencing chronic or severe pain. People with long-term conditions, such as cancer or after surgery are often prescribed prescription painkillers.
- The most popular painkillers are based on their ability to relieve discomfort.
- Non-Steroidal Anti-Inflammatory Devices (NSAIDs), are drugs that relieve pain by reducing inflammation. NSAIDs include naproxen, aspirin, and ibuprofen. These meds might require a prescription from your Doc.
- Non-opioid painkillers: These painkillers lower the pain receptors within the brain and can be effective in relieving moderate to severe acute pain. Paracetamol, antidepressants, such as amitriptyline, antidepressants (such as pregabalin or gabapentin), aspirin, and other NSAIDs are some of the most common non-opioid painkillers. To temporarily reduce pain, non-opioid medications such as capsaicin and lidocaine can be applied topically to the skin.
- Opioid analgesics – Opioid painkillers like tramadol and fentanyl help reduce pain by blocking the transmission of pain signals from the brain. These painkillers should not be taken without consulting a physician.
- Combination painkillers are a combination of two types of analgesics. Patients have often been prescribed a combination of tramadol/paracetamol to treat severe pain.
What are the side effects associated with painkillers?
- Painkillers are a blessing if used responsibly and as directed by a doctor. Excessive use of painkillers can cause side effects like nausea, vomiting, and sleep disturbances.
- You may also experience serious side effects from taking painkillers frequently:
- Analgesic tolerance is the body’s ability to tolerate painkillers in excess. This can reduce their effectiveness.
- Addiction: Long-term opioid use can lead to a tolerance for the medication, which may increase the need for higher doses. This can lead to drug addiction.
- Gastric problems: Long-term use of NSAIDs or opioids can cause gastrointestinal problems such as constipation and indigestion, stomach pains, internal bleeding, stomach ulcers, and stomach cramps.
- Skin problems: Excessive usage of NSAIDs may increase the risk of rashes, blisters, and bleeding.
- Liver disease: High doses of paracetamol or alcohol combined with it can cause liver damage.
- Heart attack and stroke: Other than aspirin, a blood-thinning medication, overuse of NSAIDs can increase the risk of heart attack or stroke.
When should you contact your doctor?
If you experience any side effects from painkillers, it is important to immediately contact your doctor. These symptoms may include:
- Breathing difficulties
- Blurring of vision
- Numbness and drooping of the eyelids or side of your mouth
- Slogarious speech
- Difficulty swallowing
- Diarrhea accompanied by severe abdominal pain
- Haematuria is the presence of blood in the urine.
How to effectively use painkillers?
- Before you take any painkillers, make sure to consult your doctor.
- Limit the number of painkillers you take to your home for more than a few consecutive days.
- Start with the lowest possible dose when you are trying a new medication. This reduces the chance of side effects and complications.
- You should not exceed the daily maximum dose of medication. You can check the medication information leaflet for the maximum dosage or talk to your doctor.
- Share your pain-relief medication only with yourself.
- Consult your doctor if the pain persists after taking the painkiller.
Conclusion
The majority of painkillers that are available over the counter can be used to relieve mild to moderate pain. These medications can have side effects that could lead to serious health problems. Regular users of painkillers should consult their doctor in order to determine the best course of action and prevent adverse reactions.
