How Long After Bactrim Can I Drink?

Before one delves into the deeper questions, understanding the composition and activity of the drug is necessary. In this way, it will become easy to reach a valid and logical conclusion, enough to impose the fact that drinking should be postponed for at least a few hours, if not days (though most of the doctors are of the latter view).

The concerned drug, that is, Bactrim has two compounds – sulfamethoxazole and trimethoprim. They are excellent antibiotics and dissolve in the body in no time. It might be intriguing to know why alcohol consumption is such a menace. There are scientifically proven reasons for the same.

The compounds which constitute this drug react quickly with alcohol, and the reaction is not really good for the human body, Such an instance might turn fatal if not controlled and treated at the right time. What happens exactly when someone consumes alcohol right after taking a Bactrim?

The by-products of the aforementioned reactions inhibit the secretion of enzymes in the body. Since enzyme production is hindered, toxic substances begin to get accumulated in different places and all this culminates into a health hazard. This condition can be easily prevented by contacting the doctor at regular intervals.

If the person is fit and fine, a four-hour limit is sufficient. In the case of people suffering from other ailments, including liver problems, it is advisable to keep a gap of at least twenty-four hours after taking Bactrim orally.

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 generally 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.
