Description

Lafaxine ER (100mg) is an oral medication manufactured by Genix Pharma, formulated to help manage major depressive disorder (MDD) in adults who require a higher dose than the standard strength for an adequate treatment response. Each pack contains 14 extended-release tablets, with each tablet containing Desvenlafaxine, an active substance belonging to a class of medicines known as serotonin-norepinephrine reuptake inhibitors (SNRIs). This medicine works by helping to restore the balance of certain natural chemical messengers in the brain, namely serotonin and norepinephrine, which play a role in regulating mood. The extended-release formulation is designed to release the active ingredient gradually over time, allowing for a once-daily dosing schedule. This 100mg strength is generally considered for patients who have been started on a lower dose and require an increase based on their doctor’s assessment of symptom response and tolerability. Lafaxine ER should only be taken under the guidance of a qualified physician, who will assess an individual’s mental health history, current symptoms, and any other medicines being taken before confirming this strength is appropriate.

Ingredients

Each extended-release tablet of Lafaxine ER (100mg) contains Desvenlafaxine 100mg as its active pharmaceutical ingredient, an SNRI that works by inhibiting the reuptake of serotonin and norepinephrine in the brain, helping to increase the availability of these mood-regulating chemical messengers. This strength delivers double the active ingredient found in the standard 50mg formulation, which is why it is generally reserved for patients requiring a stronger therapeutic response. The tablet also contains standard pharmaceutical excipients such as binders, fillers, and an extended-release coating system, which controls the gradual release of the active ingredient and supports the tablet’s physical stability without contributing any therapeutic effect of their own.

Dosage Form

Lafaxine ER is available as an extended-release oral tablet, with each pack containing 14 tablets. The extended-release design allows the medicine to be released steadily into the body over time, supporting a consistent once-daily dosing routine as directed by a treating physician.

Uses

Lafaxine ER (100mg) is primarily used for the treatment of major depressive disorder in adults, helping to address symptoms such as persistent low mood, loss of interest in daily activities, changes in sleep or appetite, and reduced energy or concentration. This higher strength is generally considered for individuals whose symptoms have not responded sufficiently to the standard 50mg dose, offering an increased level of the active ingredient under continued medical supervision. As with lower strengths, treatment outcomes and suitability can vary between individuals, and ongoing evaluation by a healthcare provider remains an important part of managing depression effectively at this dose.

How to Use

Lafaxine ER should be taken exactly as prescribed by a doctor, typically once daily, at approximately the same time each day, with or without food. The tablet should be swallowed whole with a glass of water and should never be crushed, chewed, or split, as doing so could interfere with the extended-release mechanism and cause the medicine to be released too quickly. Given that this is a higher strength, any increase to this dose should only occur gradually and under a doctor’s direct supervision, typically after a period of treatment at a lower dose. Antidepressant medicines generally take a period of consistent use, often several weeks, before their full effect becomes noticeable. This medicine should never be stopped abruptly without medical guidance, as doing so can lead to discontinuation symptoms; any changes to dosage or plans to stop treatment should always be made gradually under a doctor’s supervision. If a dose is missed, it should be taken as soon as remembered, unless it is close to the time of the next scheduled dose, in which case the missed dose should be skipped rather than doubled.

Side Effects

Lafaxine ER may cause side effects in some individuals, and because this is a higher strength, certain effects may be more pronounced compared to the standard dose. Commonly reported effects include nausea, dry mouth, dizziness, headache, excessive sweating, and changes in sleep patterns. Less commonly, some individuals may experience increased blood pressure, changes in appetite, or sexual side effects. As with other antidepressant medicines, there is a recognized risk of changes in mood or the emergence of new or worsening suicidal thoughts, particularly during the early weeks of treatment or following dose changes such as an increase to this strength, and this risk may be more pronounced in younger patients. Close monitoring by a caregiver or healthcare provider during this period is generally recommended. Any severe or persistent symptoms, or signs of a serious reaction such as significant mood changes, unusual bleeding, or an allergic reaction, require prompt medical attention. This list is not exhaustive, and a healthcare provider should be consulted for a complete understanding of possible reactions at this strength.

Pregnancy & Breastfeeding

Lafaxine ER should be used during pregnancy only if a doctor determines that the potential benefit justifies the potential risk, as SNRIs taken during pregnancy, particularly later in pregnancy, have been associated with certain risks to the newborn, including withdrawal-like symptoms after birth. Women who are pregnant, planning a pregnancy, or suspect they may be pregnant should discuss their treatment with their doctor rather than stopping the medicine on their own, since untreated depression also carries risks. Use during breastfeeding should similarly be discussed with a healthcare provider, as the active ingredient may pass into breast milk. Any decision regarding use during pregnancy or lactation should be made only through careful consultation with a qualified healthcare professional.

Storage Instructions

Lafaxine ER tablets should be stored in a cool, dry place away from direct sunlight, excessive heat, and moisture, ideally below 30°C. The tablets should remain in their original packaging until ready for use, and the product should always be kept out of the reach and sight of children. Tablets should not be used beyond their printed expiry date, and any unused or expired medicine should be disposed of responsibly according to local pharmaceutical waste guidelines rather than discarded in regular household trash.

FAQS
