(1-1) Best over the counter drugs for IBS pain relief:

Option 1: Peppermint oil.

Best option for peppermint oilIBgard® for Irritable Bowel Syndrome (IBS).

Peppermint oil is one of the most widely used over the counter drugs for IBS

It is also known for its good safety profile.  pharmacists think that the soothing effects of peppermint oil are due to a substance called menthol.

How does peppermint oil work for IBS

  • It decreases the contractions of smooth muscles of the colon thus decreasing your abdominal pain.
  • It regulates the motility of your gut it is specifically beneficial in IBS diarrhea.
  • It also helps to reduce IBS gas and bloating.

 

When to take peppermint oil

Many clinical trials studied the antispasmodic effects of peppermint oil. Most of them concluded that people menthol can be used as a first-line therapy or abdominal pain

This is because of its efficacy and in the safety of the drug over other prescription antispasmodics

You can use peppermint oil for:

  • IBS abdominal pain
  • IBS gas and bloating
  • IBS diarrhea
  • Also, with mild constipation

 

How to take peppermint oil

  • Enteric-coated capsules are better, as they bypass your stomach and cause fewer side effects.
  • The usual dose of enteric-coated capsules is 1 or 2 capsules three times daily.
  • I usually prescribe peppermint oil as the first choice for relieving IBS abdominal pain. Even before the famous prescription antispasmodic drugs.
  • Peppermint oil used for short term periods, if you plan to use it for longer than one month, please consult your doctor.

 

Peppermint oil side effects:

  • Usually minimal and only appears in larger doses.
  • The most common side effect is heartburn. The peppermint oil capsule form protects your stomach from this side effect.
  • Others (rare): allergic reactions, headache, burning anal pain.

(1-2) Best over the counter drugs for IBS pain relief:

Option 2: Buscopan IBS Relief

 Boehringer Ingelheim Buscopan Ibs Relief at amazon.com

 

 

My second drug of choice for relieving pain associated with IBS is Hyoscine Butyl bromide (Buscopan IBS relief)

Buscopan is first discovered in Germany in the 1950s and is widely used as an antispasmodic relieving abdominal colic.

It is available as over the counter drug in many countries including the United States.

I’ll cover some points you should know before you decide to and take this drug 

  • How Buscopan works.
  • Why and when you should take Buscopan.
  • How to take the drug.
  • When you shouldn’t take Buscopan.
  • The possible side effects.

 

How Buscopan works 

IBS pain results from contractions of the muscles in the wall of your intestine. these contractions are involuntary and you cannot control it.

The presence of trigger foods or excess gas inside your intestine will trigger your smooth muscle to contract and cause you pain.

Buscopan inhabits these smooth muscle contractions in your intestine. Thus making your colon walls relax and relieve the sense of pain and colic.

Although not widely prescribed inside the United States, it is available is over the counter drug on amazon.com.

The tablet form is usually very safe only a small fraction is absorbed into your blood.

 

Why and when you should take Buscopan

  • When your IBS abdominal  being cannot be controlled by  diet control
  • When you want an instant pain reliever for your IBS

 

How to take the drug

  • The starting dose is one tablet 3 times per day.
  • The dose can be increased gradually up to 2 tablets 4 times per day (which I don’t recommend).
  • The tablet is taken as a whole with a glass of water.
  • You can take it with or without food but I recommend you take it 15 minutes before your meal.
  • Don’t take the drugs for longer periods maximum of 14 days.
  • It is better to consult your doctor before you take Buscopan.

 

The possible side effects of Buscopan:

Generally, the tablet form is safer than the injection form as it is poorly absorbed from your intestine to blood, so it causes fewer side effects.

These side effects include 

    •  less than 1%: Awareness of Heartbeats (palpitation or tachycardia), dry mouth, blurred vision and mild skin reactions like hives or Itching.
    •  less than 1 per 1000: Difficulty passing urine.

  • Extremely rare: Allergic reaction to hyoscine butylbromide

 

When you shouldn’t take Buscopan.

  • If you don’t have a medically confirmed IBS.
  • If you experience abnormal symptoms with IBS like vomiting fever or passage of bloody stools.
  • If you have glaucoma in your eyes.
  • Better to be avoided with pregnancy and lactation.
  • If you have severe constipation.
  • If you have a condition called benign prostatic hypertrophy.
  • If you are taking antipsychotic or anti-Parkinson medications.
  • If you are taking other antispasmodics or antihistamine drugs.

(2) Best over the counter drugs for IBS-Diarrhea:

Best option is: Immodium

 Imodium A-D Anti-Diarrheal Softgels

Loperamide or Imodium is the go-to drug used for diarrhea.

It is an extraordinarily safe drug that is used for people with IBS predominant diarrhea.

How Imodium works

  • It decreases the movement of your interesting thus slowing down the passage of contents.
  • It increases the absorption of fluid and nutrients from your intestine into the blood.
  • It prevents the secretion of fluids into your intestinal lumen thus preventing the formation of loose stools.

When to take Imodium:

  • You can take Imodium if you have IBS diarrhea with or without abdominal pain.
  • Imodium is also beneficial if you have the mixed type of IBS where there is constipation alternating with diarrhea

When not to take Imodium:

  • If you have IBS constipation.
  • better not use with Buscopan IBS relief.
  • If your diarrhea is not due to IBS (diarrhea not associated with food, awakens you at night or associated with fever).  It is better to consult your doctor
  • If you have IBS pain without diarrhea.
  • If you have dysentery, inflammatory bowel syndrome, or a condition called membranous colitis.

Imodium dose and how to take:

  • According to this study, the required dose usually is 2 to 4 milligrams (mg) per day for IBS diarrhea.
  • The maximum daily dose for adults is 16 mg But I recommend you never exceed 8 mg per day
  • Each tablet Imodium contains 2 mg loperamide and it is taken once daily and you can increase the dose gradually to 4 or 6 milligrams day until diarrhea stops. 

 

Imodium side effects

The side effects are usually rare, and so the drug is safe. They include:

  • Constipation especially with higher doses.
  • Some nausea, dizziness, and abdominal cramps.
