How long after last consuming alcohol do you have to wait before taking tylenol (acetaminophen)? The alcohol consumed was 3 standard drinks, 24 hours ago.

How long after last consuming alcohol do you have to wait before taking tylenol (acetaminophen)?  The alcohol consumed was 3 standard drinks, 24 hours ago.

You are clear to use: The alcohol is broken down in the liver using the same toxin removal system as the acetaminophen. If used at the same time their is some chance of a toxic effect on the delicate liver cells. Since the half life of alcohol is a couple of hours, the material is long gone and you can use the medication without any problem. ...Read more

Does it hurt to get a steroid shot on your shoulder? If it does, can you take Tylenol (acetaminophen) afterwards? And How long does the inflammation last?

A tiny bit: If done as usual, you would receive a little local anesthetic that would sting until it puts the skin to sleep. Local anesthetic is usually given with the steroid (ask!) so that actually you may be pain free for several hours. During this time your doc may advise you to move the shoulder through the full range of motion, depending on diagnosis. Inflammation relieved in days. Tylenol (acetaminophen) is fine. ...Read more

URI - germ vs host: Illness results from two factors: the germ causing it and the patient fighting it. Probably you have an Upper Respiratory tract Infection (URI) and your body is trying to fight it off. I suspect a virus of the hundreds of different causes. If you're low on sleep, not eating right, stressed, smoking/drinking alcohol- all of those will make it harder for you to fight something off. Try to see a doc. ...Read more

Hv bronchitis 8 wks developed into sinusitis. Headache + press behind eyes. How long will this last? Does it cause any vision loss? Tkg.Tylenol (acetaminophen) pain

Aggressive treatment: 8 weeks of bronchitis and now sinusitis tells me that you have upper and lower respiratory systems infected or inflamed. There needs to be culture of your sputum, lab, chest and sinus xrays. Prolonged antibiotics are indicated IF there is infection. Ancillary treatments are inhalers, decongestants , maybe steroids and lots of hydration. Vision loss is rare . Please see your physician ASAP. ...Read more

I've had a Head ache on the right side of my head for the last 6 days. No dizziness, no side effects. Tylenol (acetaminophen) works but when wore off, pain is back.

I've had a Head ache on the right side of my head for the last 6 days. No dizziness, no side effects. Tylenol (acetaminophen) works but when wore off, pain is back.

Focal headache: Because you are young the most probable answer will be migraine driven by stress (migraine by itself only tends to last for a few hours, or until sleep). Being on Celexa (citalopram) might support this possibility. On the other hand, focal persistent headache raises the question of a "secondary headache" disorder where headache is a symptom of another disorder. Probably should see you PCP for eval. ...Read more
