Pregal M

Yes, there may be some undesirable effects associated with Pregal M such as acne, acne-rosacea (redness of the face) and some allergic reactions.

Pregal M is an active form of vitamin B12. It is available in the form of oral, parenteral, and sublingual (under the tongue) formulations. It is used to treat B12 deficiency, Alzheimer's disease, diabetic neuropathy (nerve damage due to diabetes), visual function, rheumatoid arthritis, Bell's Palsy (facial paralysis or temporary weakness of the facial muscles), sleep-wake rhythm (irregular sleeping pattern) disorder and neuropathic pain.

The Pregal M can be used for the treatment of subacute herpetic neuralgia (pain that persists for 30 to 120 days following a rash by herpes zoster), glossopharyngeal neuralgia (extreme pain at the back of the tongue, throat or ears) and trigeminal neuralgia (extreme pain caused via trigeminal nerve from face to the brain).

Pregal M works by forming myelin sheath which is used to cover and protect the nerve cells. Pregal M is used to revive the nerve cells. In the absence of enough Pregal M, myeline sheath doesn't form properly leading to nerve damage.

Methylcobalamin is abundantly found in eggs, milk, curd, meat (chicken and fish). However, if your levels are very low you are recommended to take medicines as per doctors instructions.
