Why Can I Drink So Long After Bactrim?

In this case, the answer is quite direct. One must wait for some time before drinking once Bactrim is consumed because the medicine is quite reactive. For unhealthy individuals, the side effects might be exaggerated beyond normal conditions if the drug is followed by heavy drinking.

Since incomplete knowledge is a lot more dangerous than no knowledge at all, one must stay abreast with all the nuances related to a specific drug. It is common to think that Bactrim is simply an antibiotic used to treat minor infections in the body.

What threat does a bit of casual drinking pose? This must be taken as a warning instead of a threat – the combination of Bactrim components and alcohol might prove to be deadly at times. Another factor that is sure to encourage people to enhance the gap is the efficiency of the medication.

It is a widely accepted fact that alcoholic drinks slow down the innate metabolism of the body. This is a clear indication of the fact that the antibiotic will soon lose its efficiency if large amounts of liquor are consumed thereafter. For sick people, dullness might be increased to greater levels, thus interfering with daily life activities.

A day after Bactrim is taken, it is sure to have acted well and it then passes out of the body with immediate effect. Therefore, it is considered safe enough to indulge in drinking the next day. In other words, wait for at least twenty-four hours.


Each body reacts differently to different medications and the side effects also vary a lot from person to person. As far as Bactrim is concerned, it is a simple and much commonly used antibiotic. It comes with negligible instructions and the consumer is supposed to take only a reasonable amount of care while the course is going on.

Alcohol consumption is forbidden immediately after taking medicines. As mentioned before, antibiotics take a little longer. Therefore, having patience is essential in this case. Irrespective of the purpose of the medication, one must conform with the general physician once.
