Migraine attacks. Be highly appreciated.

From childhood onwards, I have migraine issues for which I've been trying different treatments. Since the last couple of months, my migraine issues have gone worse and I consulted an ENT specialist. He prescribed Tryptomer 10mg and Betacap Tr 80. I'm taking these medicines for the last few months and happened to miss a few dose recently which resulted in experiencing severe migraine attack. I'm confused now that how long I've to take these medicines or Are these some kind of habit forming medicines. Because whenever I'm missing a dose, I used to have severe headache. Kindly advise me if it is safe to take these medicine for long periods or it has got any side effects. Also if there is any alternatives for this medicine if this has any side effects. Your kind advise will be highly appreciated. Thank you in advance.
