Rizatriptan 5?mg is usually safe for weekly migraines, but using it too often can cause side effects or rebound headaches. You can also use paracetamol, safe painkillers like NSAIDs, or preventive medicines your doctor recommends. Always consult your doctor before starting or changing any migraine medicine.

Taking rizatriptan too often or for too long can worsen your headaches or make them more frequent over time. To avoid this, you should not use rizatriptan for more than 10 days in a month. Consult a doctor if you find yourself needing rizatriptan to treat more than 4 headaches in one month.
