Zoloft

Are there any serious warnings or precautions that I should know about?


Serious Warnings and Precautions

New and worsened emotional or behaviour problems:

  • When you first start taking ZOLOFT or when your dose is adjusted, you may feel worse instead of better. You may feel new or worsened feelings of agitation, hostility, anxiety or impulsivity.
  • During your treatment with ZOLOFT, it is important that you and your healthcare professional talk regularly about how you are feeling. They will closely monitor you for signs of new or worsened emotions or behaviours while you are taking ZOLOFT.
  • You may find it helpful to tell a relative or close friend that you depressed. Ask them to read this webpage or the leaflet that comes with your medication. You might ask them to tell you if they:
    • think your depression is getting worse, or
    • are worried about changes in your behaviour.
  • If your depression worsens or you experience changes in your behaviour, tell your healthcare professional right away. Do not stop taking your medicine as it takes time for ZOLOFT to work.

Self-harm or suicide:

  • Antidepressants, such as ZOLOFT, can increase the risk of suicidal thoughts and actions.
  • If you have thoughts of harming or killing yourself at any time, tell your healthcare professional or go to a hospital right away. Close observation by a healthcare professional is necessary in this situation.

Other warnings you should know about:

Pregnancy: Only take ZOLOFT during pregnancy if you and your healthcare professional have discussed the risks and have decided that you should. If you take ZOLOFT near the end of your pregnancy, you may be at a higher risk of heavy vaginal bleeding shortly after birth. If you become pregnant while taking ZOLOFT, tell your healthcare professional right away.

Effects on newborns: In some cases, babies born to a mother taking ZOLOFT during pregnancy may require hospitalization, breathing support and tube feeding. Be ready to seek medical help for your newborn if they have trouble breathing or feeding, muscle stiffness or floppiness, seizures, jitteriness, or constant crying.

During early pregnancy, there may be a slight increase in the risk of heart defects in the newborn. In late pregnancy, there is a risk of Persistent Pulmonary Hypertension of the Newborn (PPHN), which causes breathing problems.

Falls and fractures: ZOLOFT can cause you to feel sleepy or dizzy and can affect your balance. This increases your risk of falling, which can cause fractures or other fall related-injuries, especially if you take sedatives, consume alcohol, are elderly, or have a condition causing weakness or frailty.

Serotonin toxicity (also known as Serotonin Syndrome): ZOLOFT can cause serotonin toxicity, a rare but potentially life-threatening condition. It can cause serious changes in how your brain, muscles and digestive system work. You may develop serotonin toxicity if you take ZOLOFT with certain anti-depressants or migraine medications. Serotonin toxicity symptoms include:

  • fever, sweating, shivering, diarrhea, nausea, vomiting;
  • muscle shakes, jerks, twitches or stiffness, overactive reflexes, loss of coordination
  • fast heartbeat, changes in blood pressure;
  • confusion, agitation, restlessness, hallucinations, mood changes, unconsciousness, and coma

  • Angle-closure glaucoma (sudden eye pain or change in vision)
