Why is this medication prescribed?

Mestinon Timespan is a brand name for a medication called Pyridostigmine extended-release tablets. It is primarily prescribed to treat a condition called myasthenia gravis. Myasthenia gravis is an autoimmune disorder that affects the neuromuscular junction, leading to muscle weakness and fatigue. Pyridostigmine, the active ingredient in Mestinon Timespan, works by increasing the levels of a neurotransmitter called acetylcholine in the body. Acetylcholine is necessary for proper muscle function, and Mestinon Timespan helps improve muscle strength and control in individuals with myasthenia gravis.

How should this medicine be used?

Here are some general guidelines on how Mestinon Timespan should be used, but it’s essential to follow your doctor’s specific instructions:

• Dosage: The dosage of Mestinon Timespan can vary depending on the severity of your myasthenia gravis and your individual response to the medication. Your doctor will prescribe the appropriate dose for you.
• Timing: Mestinon Timespan is usually taken on an empty stomach, at least 30 minutes before or 2 hours after meals. This helps ensure optimal absorption of the medication.
• Extended-Release: Mestinon Timespan is an extended-release tablet, which means it releases the medication slowly over time. This allows for more stable and prolonged control of muscle function. It is typically taken once or twice daily, as prescribed by your doctor.
• Follow Instructions: Follow your doctor’s instructions carefully. Do not change the dosage or frequency of use without consulting your healthcare provider.
• Do Not Crush or Chew: Swallow the tablets whole with a glass of water. Do not crush or chew them, as this may affect the extended-release properties of the medication.
• Monitoring: Your doctor may periodically adjust your dosage based on your symptoms and response to treatment. Regular check-ups and communication with your healthcare provider are essential.
• Side Effects: Like all medications, Mestinon Timespan can have side effects. Common side effects may include stomach upset, diarrhea, increased saliva, and sweating. If you experience severe or unusual side effects, contact your doctor.
• Missed Dose: If you miss a dose, take it as soon as you remember. If it’s close to the time for your next dose, skip the missed dose and continue with your regular schedule. Do not double up on doses.
• Precautions: Inform your doctor of any other medications you are taking, as well as any underlying health conditions you have. Some medications and medical conditions may interact with Mestinon Timespan.
• Pregnancy and Breastfeeding: If you are pregnant, planning to become pregnant, or breastfeeding, discuss the risks and benefits of using Mestinon Timespan with your healthcare provider.

It’s crucial to work closely with your healthcare team when taking Mestinon Timespan to manage your myasthenia gravis effectively and minimize potential side effects or complications. Always consult your doctor or pharmacist if you have any questions or concerns about your medication.

Some off-label uses may include:

• Orthostatic Hypotension: Mestinon may be used to manage orthostatic hypotension (a drop in blood pressure upon standing) in certain cases.
• Postural Tachycardia Syndrome (POTS): Mestinon may be prescribed off-label to help manage symptoms of POTS, a condition characterized by an abnormal increase in heart rate when moving from a lying down to an upright position.
• Neuromuscular Disorders: It may be used in other neuromuscular disorders or conditions where improving nerve-to-muscle communication is beneficial.
