Hyperbolic tapering (sometimes called the Horowitz-Taylor method) is based on the fact that as antidepressant dose goes up, drug action on brain cells increases, but not in equal steps, higher dosages having less and less additional influence – a decreasing return on investment. The graph showing this is called a hyperbolic curve (goes up faster at low doses and flatter at higher doses).
Tapering based on this method gradually backs you out of the drug with reductions following this natural curve, with the size of dose reduction getting smaller as the dosage gets lower. As very low doses (e.g. 1 or 2mg) have much larger effects than people expect, many people need to taper down to very small doses before stopping so that the final ‘jump’ to zero is not too large a shock to the nervous system.
Compounded medications are often crucial in the tapering process, as commonly available dose sizes aren't small enough to reach the sizes necessary to follow a safe tapering plan. For example, the smallest available dose size for a medication like venlafaxine, as an example, is 37.5mg (a drop from 37.5mg to 0mg can easily lead to debilitating withdrawal symptoms).
Effexor can produce side effects that vary in occurrence and severity among individuals. Common side effects may include increased blood pressure, sleep disturbances, anxiety, changes in appetite, drowsiness, and gastrointestinal discomfort. Some individuals may experience changes in sexual function or increased sweating.
Long-term use of any medication requires consideration of potential risks. With Effexor, some studies have noted persistent effects on sexual function or changes in weight in some individuals. There is ongoing research into potential cognitive and cardiovascular effects associated with long-term antidepressant use in general.
The half-life of a medication is relevant to understanding its effects and potential withdrawal symptoms. Venlafaxine has a half-life of approximately 5 hours, while its active metabolite, O-desmethylvenlafaxine (ODV), has a half-life of around 11 hours. This relatively short half-life is why Effexor is typically prescribed for daily use, sometimes multiple times a day for the immediate-release form.

Outro Health provides flexible, medically-supervised tapering plan with gradual dose reductions tailored just for you. Our hyperbolic tapering method, where reductions become progressively smaller, gently minimizes nervous system disruption and withdrawal discomfort. We personalize your tapering plan based on your response, preferences, and what's happening in your life.
Safe antidepressant deprescribing requires a comprehensive approach that is often difficult for an individual prescriber to provide due to the time required. It also requires up-to-date knowledge on the latest techniques in tapering antidepressants that are not yet widely taught in the United States. Think of Outro Health as a specialist in tapering.
At Outro Health, we walk with you every step of the way. Our specialized, high-touch care team takes time to get to know you and your goals, and provides an advanced, individualized approach to tapering off antidepressants informed by the latest guidance and clinical evidence. Through Outro Health’s app, your symptoms and progress are continuously monitored by your provider, who can reach out to offer coping strategies or adapt your care plan accordingly.

The graph showing this is called a hyperbolic curve (goes up faster at low doses, and flatter at higher doses).
Tapering based on this method gradually reduces the drug following this natural curve, with the size of dose reduction getting smaller as the dosage gets closer to 0mg. These very low doses are difficult to make up with commonly available tablets, so compounded medications become important. To learn more, speak with an Outro Health clinician by scheduling your evaluation.
Many people have difficulties when they try to go off antidepressants. Our team of expertly trained clinicians will develop a tailored tapering program, informed by the latest scientific evidence and designed to minimize withdrawal effects - even for these people who have tried to stop before.
We currently offer taper management for antidepressant medications. You can see the full list here.
We are making preparations to expand to other psychotropic medications like benzodiazepines, which also follow the hyperbolic tapering method.
