Pain relievers are often the first medication we reach for when we’re in discomfort. However, knowing which one to use for each situation can be confusing with so many options available. While over-the-counter (OTC) pain relievers are generally safe when taken as directed, they still carry risks, especially if taken incorrectly. In this article, we’ll break down the effects, differences, and precautions of some common OTC pain relievers available in the U.S. market.
Mechanism of Action of Pain Relievers
Pain relievers work by blocking the production of prostaglandins, compounds in the body that trigger pain and inflammation. The two main categories of pain relievers are acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs).
– Acetaminophen affects the central nervous system, explicitly regulating serotonin (the feel-good hormone). This helps reduce pain, but it doesn’t have any anti-inflammatory effects.
– NSAIDs, on the other hand, target and block cyclooxygenase (COX) enzymes, which are responsible for producing prostaglandins. By inhibiting COX enzymes, NSAIDs reduce both pain and inflammation.
In short, while both pain relievers block prostaglandins, they do so in different ways.
Pain Relievers vs. Antispasmodics: What’s the Difference?
Pain relievers are designed to relieve general pain, while antispasmodics are specifically for muscle spasms or cramps.
Pain relievers are generally the best choice for headaches, muscle aches, or menstrual cramps. However, an antispasmodic would be more effective if you’re experiencing sharp, cramp-like pain, particularly in the abdomen (such as a stabbing feeling). Antispasmodics target muscle contractions directly and can provide faster relief than standard pain relievers.
The First Pain Reliever That Comes to Mind: Tylenol
Tylenol is usually the first brand that comes to mind when we think of pain relievers. Tylenol is an acetaminophen-based pain reliever and fever reducer. It’s commonly used to reduce fever and relieve mild pain, such as headaches, cold symptoms, or body aches. However, it doesn’t have anti-inflammatory properties. If you need relief from inflammation (such as joint pain or muscle injuries), NSAIDs like ibuprofen or naproxen would be better.
The First Anti-Inflammatory Pain Reliever: Aspirin
Aspirin is one of the oldest and most well-known anti-inflammatory pain relievers. Its active ingredient is salicylic acid. Aspirin is primarily used to reduce inflammation and lower fever. In small doses, it can also help prevent blood clots, and it is sometimes prescribed to patients at risk of cardiovascular disease.
However, aspirin is notorious for causing gastrointestinal issues, including stomach irritation and bleeding, especially when taken on an empty stomach. For this reason, it’s not the go-to choice for many people seeking pain relief. If you take aspirin, it’s important to follow your healthcare provider’s guidance, particularly if you have any gastrointestinal issues or a history of ulcers.
For Those with a Sensitive Stomach
If you have a sensitive stomach or need to take medication on an empty stomach, acetaminophen is a safer choice. Acetaminophen is much gentler on the stomach than NSAIDs, and it doesn’t cause the gastrointestinal issues associated with other pain relievers. Dexibuprofen, a newer form of ibuprofen, is also considered easier on the stomach compared to traditional NSAIDs, making it a good option for people with a sensitive stomach.
What to Take for Severe Menstrual Cramps
For severe menstrual cramps, anti-inflammatory pain relievers like ibuprofen or naproxen are highly recommended. These medications work by inhibiting the production of prostaglandins, which are hormones responsible for uterine contractions and pain during menstruation. By blocking prostaglandin synthesis, they help reduce both the pain and inflammation associated with menstrual cramps.
What to Take for Migraines
If you suffer from migraines, naproxen is a solid choice. As an NSAID, naproxen is effective for pain relief and reducing inflammation. It also has a lower risk of cardiovascular side effects than some other NSAIDs. This makes naproxen a good option for people who may be at risk for heart conditions but still need effective pain relief.
Naproxen is also the only OTC medication in the U.S. that is specifically approved for migraine treatment. Medicines like dexibuprofen may not be as effective for migraines, so it’s important to choose the right pain reliever for your specific symptoms.
Can You Take Different Types of Pain Relievers Together?
Is it safe to take acetaminophen and an NSAID (such as ibuprofen) together? Yes, it is, but with caution. Acetaminophen and NSAIDs work in different ways so that they can be combined. However, do not take two different NSAIDs together, as this can lead to an overdose and increase the risk of severe side effects, such as gastrointestinal bleeding or kidney damage. Always follow the recommended dosages and consult your healthcare provider if unsure.
Avoid Taking Pain Relievers After Drinking
It’s common to see people take acetaminophen after drinking alcohol, but this can be dangerous. The combination of alcohol and acetaminophen can cause severe liver damage. Both alcohol and acetaminophen are metabolized in the liver and share similar detoxification pathways. When you drink alcohol, your liver breaks it down into acetaldehyde, a toxic substance. To neutralize this, the liver uses a molecule called glutathione.
Unfortunately, acetaminophen also produces a toxic byproduct that requires detoxification. When you drink alcohol, your glutathione levels are depleted, and taking acetaminophen can overload your liver, making it difficult for it to process both toxins effectively. This increases the risk of liver damage. Therefore, it’s critical to avoid mixing alcohol with acetaminophen or any other medications without consulting a healthcare provider first.
Long-Term Use of Pain Relievers: What You Should Know
Prolonged use of anti-inflammatory pain relievers, such as NSAIDs, can lead to side effects such as gastric irritation, kidney damage, and allergic reactions. In rare cases, long-term use can also increase the risk of heart disease, stroke, and bleeding disorders.
Always follow the label’s dosage instructions to minimize these risks and limit the use duration. If you need to take pain relievers for an extended period, consult your doctor to ensure that it is safe for you, particularly if you have any underlying health conditions or are on other medications. Before starting a new medication regimen, inform your healthcare provider about any pre-existing medical conditions or allergies.
