4. Possible side effects
Like all medicines, this medicine may cause side effects, although not everybody gets them.
If any of the following happen, do not take more Venlasov XL Capsules. Tell your doctor immediately or go to the casualty department at your nearest hospital:
Uncommon (may affect up to 1 in 100 people)
- Swelling of the face, mouth, tongue, throat, hands, or feet and/or a raised itchy rash (hives), trouble swallowing or breathing

In its most severe form, serotonin syndrome can resemble Neuroleptic Malignant Syndrome (NMS). Signs and symptoms of NMS may include a combination of fever, fast heart beat, sweating, severe muscle stiffness, confusion, increased muscle enzymes (determined by a blood test).
- Signs of infection, such as high temperature, chills, shivering, headaches, sweating, flu-like symptoms. This may be the result of a blood disorder which leads to an increased risk of infection.
- Severe rash, which may lead to severe blistering and peeling of the skin.
- Unexplained muscle pain, tenderness or weakness. This may be a sign of rhabdomyolysis.
Frequency not known (cannot be estimated from the available data)
- Signs and symptoms of a condition called “stress cardiomyopathy” which may include chest pain, shortness of breath, dizziness, fainting, irregular heart beat.
Other side effects that you should tell your doctor about include (the frequency of these side effects are included in the list ‘Other side effects that may occur’ below):

- Prolonged bleeding - if you cut or injure yourself, it may take slightly longer than usual for bleeding to stop.
Do not be concerned if you see small white balls or granules in your stools after taking this medicine. Inside Venlasov XL Capsules are spheroids (small white balls) that contain the active ingredient (venlafaxine). These spheroids are released from the capsule into your stomach. As they travel through your stomach and intestines, venlafaxine is slowly released. The spheroid “shell” does not dissolve and is passed out in your stools. So, even though you may see spheroids in your stools, your dose of medicine has been absorbed.
