Hi, Optalidon is a combination drug that contains two active ingredients, metamizole sodium and pitophenone hydrochloride. It is commonly used to treat various types of pain, including headaches, dental pain, menstrual cramps, and muscle pain. Metamizole sodium is a non-steroidal anti-inflammatory drug (NSAID) that works by reducing inflammation and blocking pain signals. Pitophenone hydrochloride is a muscle relaxant that works by reducing muscle tension. When used for headaches, Optalidon can help alleviate pain by reducing inflammation in the head and neck region, blocking pain signals, and relaxing tense muscles. However, it is important to note that Optalidon may not be suitable for everyone, and you should always consult with a healthcare professional before taking any medication, especially if you have any underlying health conditions or are taking other medications. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Shah Hussain, General & Family Physician
