Question 3

How does Venlafaxine work?

Accepted Answer

How Venlafaxine Works

Venlafaxine belongs to a class of medications called serotonin-norepinephrine reuptake inhibitors (SNRIs). It is designed to affect the levels of two important chemical messengers in the brain: serotonin and norepinephrine.

These chemicals, known as neurotransmitters, play a key role in regulating mood, sleep, and emotions. In many people with depression or anxiety disorders, these chemicals may be out of balance. Venlafaxine helps restore this balance through the following process:

Inhibiting Reuptake: Under normal conditions, once a nerve cell releases these chemicals to send a signal, it quickly reabsorbs them. Venlafaxine blocks (inhibits) this reabsorption process.

Enhancing Communication: By preventing the chemicals from being reabsorbed too quickly, the medication increases the amount of serotonin and norepinephrine available to send messages between nerve cells.

By keeping more of these neurotransmitters active in the brain, venlafaxine helps improve mood, decrease anxiety, and reduce feelings of panic or social fear.

Question 8

What is the dosage of Venlafaxine and how do I take it?

Accepted Answer

How to Take Venlafaxine

Venlafaxine is available as a regular tablet, an extended-release tablet, and an extended-release capsule. It should be taken by mouth, typically with food. To help you remember your medication, try to take it at the same time or times every day.

The immediate-release tablets are usually taken two or three times daily. The extended-release capsules or tablets are generally taken once a day, either in the morning or in the evening.

Administration Instructions

Swallow extended-release capsules and tablets whole. Do not crush, chew, break, or dissolve them, as this can release the entire dose at once.

If you have difficulty swallowing certain extended-release capsules, you may be able to open the capsule and sprinkle the contents onto a small amount of applesauce. Swallow the mixture immediately without chewing, and follow with a glass of water.

Missed Dose

If you miss a dose, take it as soon as you remember. If it is nearly time for your next dose, skip the missed dose and resume your regular schedule. Do not take extra medication to make up for a missed dose.

Stopping Treatment

It is important to continue taking venlafaxine even if you feel well. Do not stop taking this medication suddenly without talking to your healthcare provider. Stopping abruptly can cause withdrawal symptoms. Your doctor will provide instructions on how to gradually reduce your dose over time.

Question 9

Is Venlafaxine safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

If you are pregnant or planning to become pregnant, talk to your healthcare provider about the risks and benefits of taking venlafaxine. Using this medication during the third trimester of pregnancy may cause complications in the newborn. Some infants exposed to venlafaxine late in pregnancy have experienced breathing problems, seizures, feeding difficulties, or tremors shortly after birth. These symptoms may require a longer hospital stay or medical support.

Breastfeeding

Venlafaxine passes into breast milk and may affect a nursing infant. Because of the potential for side effects in the baby, you should discuss with your doctor whether to continue breastfeeding or continue taking the medication. Your healthcare provider will help you weigh the importance of the drug to your health against the risks to the infant.

Do not start or stop taking venlafaxine without consulting your doctor, as stopping the medication suddenly can cause withdrawal symptoms.
