Beer and Aspirin, Carisoprodol, Codeine Phosphate

These two interact in 4 distinct ways. Each one is explained separately below.

Why Are There 4 Interactions?

Beer interacts with whole categories of medication. Aspirin, Carisoprodol, Codeine Phosphate falls into 4 of those categories, so it can interact with Beer in 4 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Major).

Major

CNS DEPRESSANTS

1 of 4

Why this applies to Aspirin, Carisoprodol, Codeine Phosphate

Aspirin, Carisoprodol, Codeine Phosphate falls under CNS DEPRESSANTS — the group Beer interacts with.

Concomitant use may increase sedative and other adverse effects.
Concomitant use of alcohol with CNS depressants can increase sedative and other adverse effects, potentially through inhibition of the metabolism of certain CNS depressants.
Severity Major Likelihood Likely Evidence C

Well-controlled human studies have demonstrated the likely existence of this interaction.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

This is one combination I'd really steer you away from mixing with beer. Soma Compound with Codeine packs two ingredients that already slow down your brain and body: carisoprodol (a muscle relaxant) and codeine (an opioid). Add alcohol on top and those effects stack up. You can end up much sleepier, dizzy, and uncoordinated than expected, with slower breathing being the most serious risk. Carisoprodol and codeine are both especially drowsy on their own, so even a beer or two can hit harder than you'd think.

There's also the aspirin to consider: both aspirin and alcohol irritate the stomach lining, which raises your chance of stomach upset or bleeding. Please check with your pharmacist or doctor before drinking on this medication.

NONSTEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDs)

2 of 4

Aspirin, Carisoprodol, Codeine Phosphate also falls under NONSTEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDs).

Concomitant use may increase the risk of gastrointestinal (GI) bleeding.
Concomitant use of NSAIDs with alcohol can increase the risk of GI bleeding.
Severity Major Likelihood Probable Evidence C

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing to watch with Soma Compound with Codeine: this combo pill contains aspirin, which already irritates the stomach lining and thins the blood a little. Adding beer pushes that risk higher. Alcohol and aspirin together are a well-recognized pairing for stomach bleeding, so you might see signs like stomach pain, heartburn, dark or tarry stools, or vomit that looks like coffee grounds.

There's a second concern too. The codeine in this medicine and the carisoprodol (a muscle relaxer) both cause drowsiness, and beer adds to that, making you more sleepy, dizzy, or slow to react. I'd really encourage you to talk with your pharmacist or doctor before mixing alcohol with this one.

NARCOTIC DRUGS

3 of 4

Aspirin, Carisoprodol, Codeine Phosphate also falls under NARCOTIC DRUGS.

Concomitant use of large amounts of alcohol may decrease the metabolism of narcotic drugs.
Concomitant consumption of large amounts of alcohol can decrease the metabolism of narcotic drugs.
Severity Moderate Likelihood Possible Evidence C

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

This combo pill packs a triple punch: aspirin, the muscle relaxer carisoprodol, and the opioid codeine. Two of those three (carisoprodol and codeine) already slow down your brain, and alcohol does the same thing. Drinking beer on top of this medicine can add up fast, leaving you very drowsy, dizzy, and uncoordinated. In larger amounts, that mix can dangerously slow your breathing.

Our records also note that heavy drinking may slow how your body breaks down the narcotic part, so it lingers and hits harder. On top of that, beer plus aspirin raises your risk of stomach irritation and bleeding. Please don't change your medicine on your own, but do talk with your pharmacist or doctor about drinking while taking it.

ASPIRIN

4 of 4
Concomitant use may increase the risk of gastrointestinal (GI) bleeding.
Concomitant use of aspirin with alcohol can increase the risk of GI bleeding. Conversely, some clinical research suggests that beer can significantly decrease the area under the curve (AUC) and maximum plasma concentration of aspirin, indicating decreased bioavailability.
Severity Moderate Likelihood Possible Evidence B

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

This combo pill packs three things at once: aspirin, the muscle relaxer carisoprodol, and codeine. When it comes to beer, the biggest concern is the aspirin part. Aspirin already irritates the stomach lining, and adding alcohol on top raises your chance of GI bleeding, things like stomach pain, dark or tarry stools, or even vomiting that looks like coffee grounds. The evidence here is moderate, but it's a real and well-documented risk.

There's also a separate worry I can't ignore: carisoprodol and codeine are both sedating, and alcohol stacks on that, leading to heavy drowsiness, slowed breathing, and poor coordination. Some research even hints beer may lower how much aspirin you absorb, but I wouldn't count on that for pain relief. Please run your beer habits by your pharmacist or doctor before mixing.

About Beer

What is Beer?

Beer
  • Social and recreational drinking
  • Relaxation
  • Heart health (popular belief)
  • Bone health (popular belief)
  • Source of antioxidants and B vitamins

Beer is an alcoholic beverage that contains some minerals, B vitamins, and plant compounds from hops and grain, but it is not a health supplement. Any possible benefits come only from light-to-moderate intake, and they are easily outweighed by the well-known harms of alcohol. The safest amount of alcohol for health is none, and beer should be avoided in pregnancy and breastfeeding.
