Types of Pain Relief Medicines
Pain can be relieved with medication. There are various medicines that can be used to relieve pain. In Indonesia, the classification of drugs is regulated in the Regulation of the Minister of Health Number 949/Menkes/Per/VI/2000. It explained that there are classes of over-the-counter drugs, limited over-the-counter drugs, mandatory pharmacies, hard drugs, psychotropics, and narcotics.
Meanwhile, in general, the category of pain medicines can be simplified into three types: over-the-counter, prescription, and topical drugs.
Over-the-counter drugs
Over-the-counter drugs that can be purchased without a doctor’s prescription at pharmacies or drugstores are usually used to treat mild to moderate pain. The drug is easy to obtain, but there is a risk of side effects and other impacts when used together with other drugs. There are two types of over-the-counter drugs commonly used for pain:
- Paracetamol: it is usually advised as the first treatment for acute pain.
- Nonsteroidal anti-inflammatory drugs (NSAIDs): this group of drugs works by reducing swelling and inflammation while relieving pain. For instance, aspirin, ibuprofen, and diclofenac.
Prescription drugs
You need a doctor’s prescription to obtain this kind of drugs. These drugs are generally available in pharmacies. There are at least four types of prescription pain drugs reliever:
Nonsteroidal anti-inflammatory drugs with a prescription
Besides over-the-counter drugs, there are nonsteroidal anti-inflammatory drugs that can be obtained by prescription when the dosage is higher. There are also some NSAIDs that can only be used with a doctor’s prescription, such as meloxicam and celecoxib.
Opioid
The opioid pain medicine class is usually used to treat moderate to severe acute pain or chronic pain experienced by cancer patients. For example, morphine.
Anti-epileptic
Anti-epileptic drugs such as gabapentin and pregabalin are commonly prescribed to patients with nerve pain or widespread musculoskeletal pain (fibromyalgia).
Antidepressant
This drug can relieve pain, for example for nerve pain and fibromyalgia.
Topical drugs
Topical drugs are drugs that are applied directly to the skin at the source of the pain. These drugs may contain types of NSAIDs such as ibuprofen or piroxicam.
Different Ways to Give Pain Relief Medicines

How to Choose the Right Pain Relief Medicines?
Since there is a wide variety of pains, the selection of right medications depends on the characteristics of the pain felt. Typically, paracetamol is a pain medicine that is first used to relieve mild to moderate pain because this over-the-counter drug is easy to be obtained. For moderate to severe pain, chronic pain, or if you are not sure which pain relievers to choose, you should first consult a doctor. The doctor will give tips on choosing the right pain relief medicines or prescribing medications according to the results of the examination.
How to Prevent Pain Medication Dependence?
Pain medications are known to cause psychological dependence. The most addictive types of pain relief medicines are opioids, such as morphine. To prevent dependence, be sure to choose the right pain medicines by prescription. The doctor can help find a solution if the patients feel dependent on medication to relieve their pain. For example, by changing drugs or limiting the frequency of use and dosage of drugs.
Pain Therapy without Drugs
Pain does not always have to be treated with medication. There is an option in the form of pain therapy without medication. For example, mind and body therapy with relaxation techniques, meditation, hypnosis, and guided imagery. This therapy is also said to be able to overcome the dependence of opioid drugs such as morphine to relieve pain. Other therapies include acupuncture, massage, as well as adjustments to diet. Therapy with alternative medicines such as herbal medicine can also be an option, but you should first consult a doctor to ensure its safety.
