Can I take Imitrex every day?

Imitrex is not meant to be taken every day. It should only be taken at the first sign of headache symptoms, and it should not be taken to prevent headaches or migraines. Taking Imitrex too often can lead to side effects, such as an increase in blood pressure, injection site reactions, nasal discomfort, and rebound headaches.

How many times can you use Imitrex in a month?

It isn’t known how safe it is to use Imitrex to treat more than 4 headaches per month on average. If you’re having more than 4 headaches or migraines per month, ask your doctor about the best treatment options.

Using migraine medications for 10 or more days per month can cause medication-overuse headaches (sometimes called rebound headaches). This means you could experience daily headaches or more frequent migraine attacks. Medications that may contribute to medication-overuse headaches include:

• Triptans, like Imitrex
• Ergotamine
• Opioids
• NSAIDs

Talk to your doctor about alternative treatments to prevent medication-overuse headaches. They can also recommend preventative options.
