FAQ
Which Effexor strengths and pack sizes can I order?
Effexor tablets are available as generic venlafaxine in 37.5mg and 75mg. The 37.5mg packs range from 30 to 360 tablets, while 75mg packs range from 10 to 360 tablets. This is generic venlafaxine, not the original Effexor. Larger packs cost less per tablet.
How is Effexor sent to Hong Kong for a longer course?
For larger Effexor orders, tracked courier takes 5 to 9 business days with online tracking. Standard airmail takes 14 to 21 business days, or 30 at most, and is untracked. Very large orders may be split into several parcels.
What other names is venlafaxine sold under?
Effexor is a brand name of venlafaxine, which is also sold as Viepax. Here, venlafaxine can be bought online as generic Effexor, and also as Venlor. These are generics, not the original brand.
How long does Effexor take to work?
Not in a day or two. Sleep, appetite and energy often change before mood does, and the effect on low mood and worry builds over several weeks — sometimes longer. The dose is raised in steps rather than all at once, which is why progress can feel slow.
Can I drink alcohol with Effexor?
Alcohol and venlafaxine both slow you down, so together they can leave you drowsy, dizzy and unsteady on your feet. The effect is strongest during the first few weeks and after any dose increase, and a night of heavy drinking can leave you flat for a day.
Can I take ibuprofen with Effexor?
Ibuprofen, naproxen and aspirin all make bleeding more likely, and venlafaxine has a mild effect on the same process, so taking them together raises the chance of stomach bleeding, nosebleeds and unexplained bruising. Dark, tarry stools are a sign that bleeding has started somewhere in the gut.
Does Effexor cause weight changes?
Appetite often drops in the first weeks and some people lose a little weight; longer courses can go either way, with a few people gaining. Nausea at the start can also put you off food.
Does venlafaxine affect sleep?
It can work both ways. Some people feel sleepy in the daytime, especially early on or after a dose increase, while others find it harder to drop off at night. Vivid dreams and nightmares are reported too, most often when a dose is being reduced.
About Effexor
What the tablets are for
Effexor is a brand name for venlafaxine, and the tablets sold on this page are generic venlafaxine in 37.5mg and 75mg strengths. It belongs to the SNRI group — serotonin and norepinephrine reuptake inhibitors — which work by leaving more of these two chemical messengers available in the brain. Depression and generalised anxiety disorder, the kind of constant worry that is hard to switch off, are the main uses. Venlafaxine also has a place in social anxiety disorder and panic disorder.
Taking Effexor tablets
A day on these tablets means two or three doses, each with a meal. Treatment begins on the lower strength and rises in steps about a week or more apart. Mood improves over several weeks, not days. Coming off is gradual too: stopping suddenly brings dizziness, anxiety, headache and nausea.
Side effects to expect
Nausea, dry mouth, sweating, constipation and sleep that feels off are the ones people notice first, and most settle within a couple of weeks. Sexual difficulties are common and tend to persist. Blood pressure can creep upwards, more so at the higher strength. A rare reaction called serotonin syndrome brings agitation, a racing heartbeat, shivering, sweating and muscle twitching. In people under 25, venlafaxine can raise thoughts of self-harm, most often in the first weeks or after an increase in dose; thoughts like these need urgent help.
Effexor, Effexor XR and Venlor
All three hold venlafaxine, in different forms. Effexor XR is the extended-release capsule, 75mg and 150mg, taken once a day because it releases the medicine slowly. Venlor is a 75mg capsule. The tablets on this page are the immediate-release version at 37.5mg and 75mg, which is why they are spaced through the day rather than taken in one go. The venlafaxine page covers the ingredient itself.
What not to mix with Effexor
Venlafaxine is never combined with an MAO inhibitor such as phenelzine or tranylcypromine — serotonin can climb to dangerous levels. The same risk, usually milder, applies to other medicines that lift serotonin: triptans for migraine, tramadol, St John's wort and some other antidepressants.
