After a headache, there are many kinds of medications to choose from, but the relief by medication alone can only provide temporary relief, not fundamental treatment or even a cure. Therefore, it is recommended to take oral medication to relieve pain, but also to have a timely examination. For example, oral pain medications such as loxoprofen, acetaminophen, and oxaliplatin tablets, and for some migraines, flunarizine hydrochloride can be taken orally, and if oral medications are not effective, ketorolac aminotriol can be applied intravenously. In some cases, if drugs are ineffective, other forms of treatment can be used, such as hyperbaric oxygen for post-traumatic headache, or oral carbamazepine for involvement headache caused by trigeminal nerve pain. Each drug has its own mechanism of action and adverse reactions, so it is important to make a clear diagnosis before further clarifying what kind of drug to take orally for relief, so that you can get twice the result with half the effort, otherwise if you take large doses of useless drugs, this may cause damage to liver and kidney function, which is not conducive to the patient’s health.
