Like all medications, Venlafaxina Retard Vir may cause side effects, although not everyone will experience them.
Do not worry if you see a small tablet in your stool after taking Venlafaxina Retard Vir. Inside the capsules of Venlafaxina Retard Vir, there is a small tablet that contains the active ingredient venlafaxine. This tablet is released from the capsule in the gastrointestinal tract. As it moves along the length of the gastrointestinal tract, venlafaxine is released slowly. The "shell" of the tablet remains undissolved and is eliminated in the stool. Therefore, although you may see a tablet in your stool, your dose of venlafaxine has been absorbed.
Allergic Reactions
If you experience any of the following effects, do not take more Venlafaxina Retard Vir. Inform your doctor immediately, or go to the nearest hospital emergency room:
