What is Pristiq?

Pristiq, with the generic name desvenlafaxine, is an oral medication indicated to treat a major depressive disorder or MDD. This could manage symptoms of depression and improve mood, feelings of well-being, and energy level.

This selective serotonin and norepinephrine reuptake inhibitor (SNRI) works on the potentiation of certain neurotransmitters in the central nervous system (CNS). It generally helps restore the balance of some natural substances in the brain. This is available in Pristiq 100 mg and 50 mg extended-release tablet forms.

How to use Pristiq

To begin, read the medication information booklet included with Pristiq. Do not take this oral drug if you have not yet fully understood the drug information, especially the warnings and precautions, in the guide provided. If you need further medical advice or have queries about this treatment, you can ask your doctor or pharmacist.

Take the extended-release tablet orally. You can take it once daily, with or without a meal, or as recommended by your doctor. Swallow the tablet whole and drink a glass of water thereafter. Do not cut, crush, or chew this extended-release drug.

Remember to take Pristiq regularly and with a dosing schedule to avoid missing a dose. Follow the exact directions provided for you. Your physician may begin with a low starting dose and slowly increase your dose to avoid severe adverse effects. Do not alter your Pristiq dosage as it depends on your medical condition, response to treatment, and other medications you are taking.

Do not stop taking Pristiq abruptly. This is to prevent Pristiq withdrawal symptoms, including a brief feeling similar to electric shock, changes in sleeping patterns, headache, fatigue, and mood swings. You must only halt this treatment through the advice of your doctor.

Precautions when using Pristiq

Before taking this medication, ensure to disclose your entire medical history with your physician, especially any history of psychiatric disorders like bipolar disorder, bleeding problems, glaucoma, hypertension, kidney disease, liver problems, heart problems, stroke, and seizure. Some medical conditions or disorders may have a significant impact on how your system will respond to this antidepressant. It is also necessary to tell your doctor about all the prescription drugs, nonprescription drugs, and herbal products (i.e., St. John’s Wort) you are taking as they may have drug interactions with this SNRI.

Be watchful for an allergic reaction while on this treatment. Do not take this antidepressant if you have a known allergy to desvenlafaxine, venlafaxine, or any inactive ingredients each tablet may contain. Signs of a severe allergic response are breathing difficulty, swelling of the face and neck, itchiness, skin rashes, and severe dizziness. You should seek emergency help immediately once you experience this.

Since patients take this for depression, always watch out for the risk of suicide. The warning signs of suicide include hopelessness, talking about dying, changes in sleeping patterns, giving away important belongings, and social withdrawal. Have the suicide hotline number on standby in case the patient manifests these signs.

This oral drug may cause dizziness, drowsiness, or blurred vision. Practice safety precautions when driving, using machinery, or doing any activities that require alertness or clear vision. You should also place a limit on your alcohol intake to avoid aggravating some side effects.

Based on clinical trials, this medication could cause harm to unborn babies and breastfed children. Thus, pregnant and breastfeeding moms should not take Pristiq unless extremely necessary.
