From the Guidelines

The recommended starting dose of Zoloft (sertraline) is 25-50 mg/day. When considering the treatment of premature ejaculation, the American Urological Association guideline suggests that sertraline can be effective at doses of 25-200 mg/day or 50 mg 4-8 hours pre-intercourse 1. However, for the treatment of depression, which is a more common indication for Zoloft, a dose of 50 mg once daily is typically recommended. It's essential to note that the dosage may need to be adjusted based on the patient's response and tolerance, with a maximum recommended dose of 200 mg daily.

  • Key considerations for dosing include:
    • Starting with a lower dose to minimize initial side effects
    • Gradually increasing the dose based on response and tolerance
    • Taking the medication exactly as prescribed and not adjusting the dose without consulting a healthcare provider
    • Being aware of potential side effects, such as nausea, headache, insomnia, or dizziness, which may occur initially but often improve over time
    • Avoiding abrupt cessation of the medication to prevent withdrawal symptoms. In clinical practice, the choice of starting dose and dosing regimen often depends on the individual patient's needs and the specific condition being treated, as well as the healthcare provider's professional judgment 1.

From the Research

Dosage Information

  • The recommended starting dose for Zoloft (sertraline) is 50 mg/day, as stated in the study 3.
  • This dose is considered the optimal dose for most patients, balancing efficacy and tolerability.
  • The study 4 also supports a starting dose of 50 mg/day, with the option to increase to 100 mg/day after one week.

Dose Adjustment

  • If patients do not show an adequate therapeutic response within 24 weeks, the dose of sertraline can be increased in 50 mg/day increments at no less than weekly intervals, up to a maximum of 200 mg/day 3.
  • However, the study 5 found no correlation between sertraline plasma levels and clinical improvement or side effects, suggesting that dose adjustment may not be strictly necessary from a clinical point of view.

Administration

  • Sertraline can be administered as a single daily dose, at any time of the day 3.
  • The study 4 also confirms that sertraline can be given as one capsule (50 mg) daily for one week, then two capsules daily for up to 11 weeks.

Note: The study 6 is not relevant to the question about Zoloft dosage, as it discusses a different medication, empagliflozin.
