Right side headache can be seen in migraine, tension headache, intracranial infection, upper respiratory tract infection, etc. It is necessary to choose the appropriate medication according to the cause of the disease, such as the application of aspirin, such as ergotamine. 1. Commonly used drugs for migraine are non-steroidal anti-inflammatory drugs (e.g. aspirin, ibuprofen, naproxen), opioid preparations (e.g. pethidine), ergot preparations (e.g. ergotamine, dihydroergotamine). 2. NSAIDs such as ibuprofen can be used to relieve symptoms of tension headache. If accompanied by symptoms of depression, antidepressants such as amitriptyline can be applied. 3. If it is caused by intracranial infection, anti-infection treatment should be actively carried out, and commonly used drugs include penicillin, chloramphenicol and vancomycin. 4. Headaches caused by upper respiratory tract infections are mainly treated symptomatically, and commonly used drugs are non-steroidal anti-inflammatory drugs, such as ibuprofen. However, it should be noted that the medication must be used under the guidance of the doctor, do not self-medication.
