What is better and safer? I have been prescribed by a neurologist this...

It is difficult to propose a specific method of treatment based on such a short description. I encourage you to make an appointment with your doctor who will adjust the treatment according to your current clinical condition. As a pharmacist, I can only give general information about medicines: Tanakan: The recommended dose is three tablets per day spread evenly throughout the day. Oral. The tablets should be taken with meals with 1/2 cup of water. https://www.gdziepolek.pl/produkty/77320/tanakan-tabletki-powlekane/apteki?pvid=41259#internetowe Flunariznum WZF: For the prevention of migraine, the drug should be used 2 tablets a day before bedtime. https://www.gdziepolek.pl/produkty/30634/flunarizinum-wzf-tabletki/apteki?pvid=71933 There are no contraindications to the simultaneous use of the drugs listed in the question. The action and composition of individual drugs can be checked by clicking on the attached links on the gdziepolek.pl website, which also allows you to book them at the nearest pharmacy. If you have any doubts about how to take medication, I encourage you to consult your doctor again. It is the doctor who decides whether to treat the patient m.in based on the history of the disease and the previous response to treatment. And if you are unable to get to your primary care doctor, the GdziePoLek.pl service also allows you to get a teleconsultation with a doctor: https://www.gdziepolek.pl/telekonsultacja I enclose materials that may be of interest: https://www.gdziepolek.pl/artykuly/leki-na-migrene https://www.gdziepolek.pl/artykuly/migrena-niezwykly-bol-glowy https://www.gdziepolek.pl/artykuly/bol-glowy-i-migrena
