Here's a list of possible side effects for Asacol..., which is one of the reasons why I asked if anyone is familiar with herbal equivalents:
GENERIC NAME: MESALAMINE - TABLET (mess-AL-uh-meen)
BRAND NAME(S): Asacol
It is recommended that all people have their kidney function tested prior to starting Asacol tablets and periodically while on Asacol therapy. Serious side effects may occur.
SIDE EFFECTS: Dizziness, indigestion, bloating, gas, belching or minor stomach ache may occur the first several days as your body adjusts to the medication. Constipation, diarrhea, weakness, hemorrhoids, cough, dry mouth, hair loss, acne, general body aches, swelling of the feet or ankles (edema) or sweating may also occur. If any of these effects persist or worsen, inform your doctor promptly. Notify your doctor promptly if you develop: chest pain, fever, sore throat, headache, stomach cramps, bloody diarrhea, rectal pain, yellowing of the eyes or skin, dark urine, unusual fatigue. In the unlikely event you have an allergic reaction to this drug, seek immediate medical attention. Symptoms of an allergic reaction include: rash, itching, swelling, dizziness, breathing trouble. If you notice other effects not listed above, contact your doctor or pharmacist.
