Pristiq Dosage

Pristiq is approved to treat severe depressive disorders in adults, often simply referred to as depression.

Pristiq Form

Pristiq is available in an extended-release oral tablet form, enabling slow release of the medication into your system.

Pristiq Strengths (25 mg, 50 mg, 100 mg)

Pristiq is dispensed in three distinct strengths: 25 milligrams (mg), 50 mg, and 100 mg.

Common Dosages

Typically, your doctor will initiate treatment with a low dose, subsequently adjusting it to achieve an optimal level tailored to your specific needs. The objective is to prescribe the smallest dose sufficient to produce the desired benefit, minimizing potential side effects.

The following text describes common dosages used or recommended. It is essential to adhere to the dose prescribed by your doctor, who will determine the most suitable dosage for you based on a variety of factors.

Depression Dosage

The initial dose of Pristiq for depression treatment is typically 50 mg, administered once per day. The lowest dose available for Pristik is 25 mg, while the highest dose (maximum dose) is 400 mg. This is known as the dose range. The lowest or highest dosage is typically administered once daily.

It's noteworthy that Pristik dosages higher than 50 mg per day have not been shown to provide enhanced therapeutic benefits, with higher dosages also increasing the likelihood of side effects. (For an in-depth discussion of Pristik's side effects, refer to this article.)

Your doctor will monitor your response to Pristik, potentially increasing the dosage if the drug is not sufficiently effective in managing your symptoms.

Ultimately, your doctor aims for you to achieve a therapeutic dose of Pristik. A therapeutic dose refers to the amount that most effectively treats your condition with minimal side effects.

Pediatric Dosage

The FDA has not authorized Pristik for use in children. If your child experiences depression, consult with their healthcare provider to discuss appropriate treatment options.

Long-term Usage

Pristik is meant to be used as a long-term treatment. If you and your doctor determine that Pristik is both safe and successful in managing your condition, you will likely continue its use for an extended period.

Frequently Asked Questions

Below are responses to some frequently asked questions related to Pristik.

What are the average, minimum, and maximum Pristik doses?

The average Pristik dose is 50 milligrams (mg). The minimum dose, available in 25 mg strength, and the maximum dose of 400 mg have been approved by the FDA. It is worth noting that doses greater than 50 mg per day have not been clinically proven to provide superior therapeutic effects, with higher doses more likely to produce side effects. (For a detailed discussion of Pristik's side effects, see this article.) Your healthcare provider can help determine the best dosage for you.

Is Pristik prescribed for anxiety?

While the FDA has not authorized Pristik for use in treating anxiety or social anxiety disorder, physicians may prescribe it for off-label use. Off-label drug use refers to situations where a medicine that has received regulatory approval is used for purposes other than those for which it was initially approved. It is essential to mention that Pristik is not typically prescribed for the treatment of anxiety disorders, given the need for more research to demonstrate its efficacy in addressing these conditions. If you are interested in using Pristik to alleviate anxiety, it is crucial to discuss this with your healthcare provider, who can recommend alternative treatment options that are both secure and effective in addressing your specific anxiety concerns.

At what dosage could my doctor prescribe 150 mg or 200 mg of Pristik?

If your symptoms of depression persist despite initial use of lower Pristik dosages, your doctor may consider increasing it to 150 mg or 200 mg. However, it should be noted that higher doses of Pristik are more likely to cause side effects. As a result, your doctor will aim to prescribe the minimum dose capable of effectively alleviating your depression symptoms, minimizing potential adverse reactions. (Learn more about Pristik's side effects by consulting this article.)

What side effects might I encounter at a 100-mg Pristik dosage?

Pristik's manufacturer has not specifically reported side effects associated with a 100-mg dose of the drug. Some side effects that may emerge while using any dose of Pristik can include:

queasiness
lightheadedness
exhaustion
perspiring
infrequent bowel movements
dryness in the mouth

Missed dose

If you miss a dose of Pristiq, take it as soon as you remember. If it’s nearly time for your next dose, skip the missed dose and resume your regular routine with your next dose. Your doctor or pharmacist can provide guidance on whether or not to take or miss a missed dose.

Keep in mind that you should not double up on doses to make up for a missed dose. Taking multiple doses can increase your risk of certain side effects. (To learn more about side effects of Pristiq, check out this link.)

To avoid missing doses, consider using a medication reminder. This could be setting an alarm or using a timer. You might also want to download a reminder app on your phone.

Factors that can affect your dosage

The Pristiq dosage your doctor prescribes will depend on various factors. These include:

the seriousness of the condition you’re treating with Pristiq
your age

Other medical conditions you may have can also affect your Pristiq dosage.

Dosage adjustments

If you have certain medical conditions, your doctor might prescribe a lower dose of Pristiq. These include kidney or liver problems, such as kidney failure or liver failure.

Make sure to inform your doctor about any kidney, liver, or other medical conditions you have before starting Pristiq treatment.

How to take Pristiq

Pristiq comes as an oral tablet that you swallow. You should not break, crush, or chew Pristiq tablets. For assistance with swallowing tablets, refer to this article. You can also speak with your doctor or pharmacist.

Pristiq can be taken with or without food. It's best to take the medication around the same time each day. This helps maintain a consistent level of the drug in your body to allow Pristiq to work effectively.

*EASY-TO-READ PRESCRIPTION LABELS AND CONTAINERS*If you have difficulty reading your prescription label, discuss this with your doctor or pharmacist. Some pharmacies offer labels with large print, braille, or a code you can scan with a smartphone to convert text to speech. If your local pharmacy doesn’t offer these options, your doctor or pharmacist may be able to suggest a pharmacy that does.

If you’re having trouble opening medication bottles, ask your pharmacist about transferring Pristiq into an easy-to-open container. They might also recommend tools to help you open bottles.

Pristiq and overdose

Taking more Pristiq than your doctor recommends can lead to serious side effects.

It's crucial that you do not exceed the dosage advised by your doctor.

Symptoms of an overdose

Overdose symptoms of Pristiq may include:

vomiting

excessive drowsiness
eyes that appear larger than usual
seizure
painful or achy muscles

An overdose of Pristiq may, in some cases, be fatal. Your doctor can provide more information.

If you take more than the suggested amount of Pristiq

If you experience severe symptoms, immediately contact 911 or your local emergency number, or go to the nearest emergency room.

Pristiq and withdrawal

Stopping Pristiq therapy too suddenly can cause withdrawal symptoms that can last days to weeks. For this reason, you should not stop taking this medication without consulting your doctor first.

infrequent bowel movements
dizziness
headache
anxiety
irritability or agitation (feeling nervous, annoyed, or restless)
