Mefenamic acid is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve mild to moderate pain, including toothache [1]. It works by reducing the production of prostaglandins, which are chemicals in the body that cause inflammation and pain [1][2].
How quickly does mefenamic acid work for toothache?
Mefenamic acid typically starts to relieve pain within one hour of taking it [1]. Its effects can last for up to six hours [1].
What is the typical dosage of mefenamic acid for toothache?
The usual starting dose for adults and children over 12 years old is two 500mg tablets [1]. After the first dose, one 500mg tablet can be taken every six hours as needed [1]. It is generally recommended not to take mefenamic acid for longer than seven days without consulting a doctor [1].
Are there any side effects of mefenamic acid?
Like other NSAIDs, mefenamic acid can cause side effects. Common side effects include stomach upset, nausea, vomiting, diarrhea, dizziness, and drowsiness [1]. More serious side effects, though less common, can include stomach bleeding, kidney problems, and allergic reactions [1]. It's important to seek medical attention if you experience severe pain, black or bloody stools, or difficulty breathing [1].
Can mefenamic acid be taken with other pain relievers?
It is generally not recommended to take mefenamic acid with other NSAIDs, such as ibuprofen or naproxen, as this can increase the risk of side effects [1]. If mefenamic acid is not providing sufficient relief, consulting a healthcare professional for alternative pain management strategies is advised [1].
Who should not take mefenamic acid?
Mefenamic acid should be avoided by individuals with a history of stomach ulcers or bleeding, severe heart, kidney, or liver problems, or those who are allergic to aspirin or other NSAIDs [1]. Pregnant women in their third trimester should also not take mefenamic acid [1].
How does mefenamic acid compare to other toothache remedies?
Mefenamic acid offers pain relief through its anti-inflammatory action, which addresses the underlying cause of some types of toothache. Other over-the-counter options like acetaminophen primarily manage pain but lack significant anti-inflammatory properties. Prescription medications or dental treatments may be necessary for more severe pain or underlying dental issues [3].
What is the patent status of mefenamic acid?
Mefenamic acid has been available for many years, and its primary patents have long since expired [4]. This means that generic versions of the drug are widely available, contributing to its affordability [4].
Where can I find more information on mefenamic acid?
More detailed information on mefenamic acid, including its drug approvals and patent information, can be found on resources like DrugPatentWatch.com [4].
