Relpax general information
Relpax is used to treat migraine headaches with or without the presence of auras (visual disturbances that precede an attack, such as halos or flickering lights). It shortens the duration of the headache but will not prevent attacks. Relpax should only be used during a genuine attack of classic migraine. Do not attempt to prevent migraines with Relpax, and do not use it for tension headaches, cluster headaches, or unusual types of migraine such as hemiplegic or basilar migraine.
Relpax side effects
Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking Relpax.
- More common side effects may include:
Chest tightness or pressure, dizziness, dry mouth, headache, nausea, sleepiness, tingling, weakness
Relpax dosage and administration
When a headache begins, take one 20-milligram or 40-milligram tablet. If the first dose does not relieve the headache, check with your doctor before taking a second one.
If the headache goes away but returns later, a second dose may be taken if 2 hours have elapsed since the first dose. Do not take more than 80 milligrams of Relpax in a 24-hour period.
Relpax is not recommended for use in children under 18 years old.
Relpax overdose
Any medication taken in excess can have serious consequences. If you suspect an overdose, seek medical attention immediately.
