Prior to therapy initiation

Before you set out venlafaxine, give your prescriber and pharmacist a complete history and a current list of all medicines, including supplements and herbal products. Important items to mention include:

• High blood pressure, heart disease or a history of myocardial infarction
• Hepatic and renal impairment
• Previous seizures, head trauma or conditions that lower seizure threshold
• A history of bipolar disorder or mania in the patient or their relatives
• Thyroid disorders or unexplained weight change
• Glaucoma or raised intraocular pressure
• Known allergy to venlafaxine or constituents of the capsule
• Active suicidal ideation, recent self-harm, or severe depressive episodes
• Pregnancy, preparing for pregnancy, or breastfeeding
• Use of Perennial herb Hypericum perforatum or other products that affect serotonin

Younger people require careful supervision by a specialist prescriber. Ask about expected time to benefit, likely adverse reactions and what watchful oversight will be arranged.

Dosing and administration workflow

• Swallow extended-release capsules whole with water. Do not chew, crush or open the capsules unless you have an authorised a secondary option formulation.

• Do not change the dose or frequency without consulting your prescriber. Dose changes will depend on clinical response and tolerability.
• If you have taken venlafaxine for a long period, do not stop abruptly; arrange a supervised taper to reduce the risk of withdrawal symptoms.

If you have difficulty swallowing capsules, ask your pharmacist about available other possibilities or safe administration methods.

Interactions across networks caused by medicines

Contraindicated or high-risk combinations

• Monoamine oxidase inhibitors (MAOIs) such as phenelzine or tranylcypromine, alongside the antibiotic linezolid. Maintain appropriate washout intervals (commonly at least 14 days) before switching over to the new configuration.
• Concurrent use with other SNRIs or combining with venlafaxine-like agents increases adverse effect risk.
• The medicinal herb St Johns wort and tryptophan supplements because of the potential for serotonin syndrome.
• Certain older monoamine agents such as nefazodone may be problematic.

Drugs requiring caution and performance monitoring

• Other antidepressants and many antipsychotic medicines
• Migraine triptans, for example sumatriptan
• Drugs that affect bleeding risk: warfarin, aspirin and non-steroidal anti-inflammatory drugs
• Some antihypertensives and antiarrhythmics
• Antiviral agents and other medicines that change liver metabolism (for example ritonavir)
• Opioids such as tramadol and stimulant drugs that affect the central nervous system

This list is illustrative and not exhaustive. Give a full list of current medicines to your healthcare team and avoid alcohol and recreational drugs while you are adjusting to treatment. For safe switching between antidepressants see regulatory and clinical guidance.

Guarding measures with ongoing tracking and monitoring of performance

• Treatment benefits may take several weeks; keep follow-up visits so response and unfavorable effects can be reviewed.
• Measure blood pressure and certify the results heart rate at baseline and periodically because venlafaxine can raise blood pressure in some people.
• Monitor mood closely for any deterioration, new agitation, increased anxiety or suicidal thoughts, especially after starting or changing dose.
• Plan a taper with your prescriber before stopping to avoid withdrawal symptoms from abrupt cessation.
• Avoid driving or operating heavy machinery until you know how venlafaxine affects you; drowsiness, dizziness or blurred vision may occur and can be worse with alcohol.
• When taking over-the-counter cold, cough or allergy medicines, consult your pharmacist to reduce the risk of additive effects.
