Megatab is used to treat acute migraine headaches and is an effective medication that helps relieve the symptoms associated with this type of headache. The medication works by narrowing the blood vessels in the brain, which helps reduce the signals responsible for pain. This medication is usually used when the first signs of an attack begin or immediately after feeling the onset of a headache. It is not taken to prevent migraines or to reduce the number of attacks.
Megatab may be useful for people who suffer from cluster headaches, which is a more severe and less common type of headache. The medication relieves symptoms related to headaches such as extreme sensitivity to light or sound. However, it is not suitable for treating other types of headaches such as normal tension.
