What happens if I miss a dose (Precose)?
Take the missed dose as soon as you remember (be sure to take it with a meal). If it has been longer than 15 minutes since you started your meal, you may still take acarbose but it may be less effective than taking it with the first bite of the meal. Do not take acarbose between meals, and do not take extra medicine to make up a missed dose.
What happens if I overdose (Precose)?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
Overdose symptoms may include bloating, gas, or stomach discomfort.
In case of overdose, do not eat or drink anything containing carbohydrates for the next 4 to 6 hours.
What should I avoid while taking acarbose (Precose)?
Avoid drinking alcohol. It can lower your blood sugar.
Avoid taking a digestive enzyme such as pancreatin, amylase, or lipase at the same time you take acarbose. These enzymes can make it harder for your body to absorb acarbose. Products that contain digestive enzymes include Arco-Lase, Cotazym, Donnazyme, Pancrease, Creon, and Ku-Zyme.
What other drugs will affect acarbose (Precose)?
You may be more likely to have hyperglycemia (high blood sugar) if you are taking acarbose with other drugs that raise blood sugar. Drugs that can raise blood sugar include:
- isoniazid (for treating tuberculosis);
- digoxin (Lanoxin);
- niacin (Advicor, Niaspan, Niacor, Simcor, Slo Niacin, and others), nicotine patches or gum;
- diuretics (water pills);
- steroids (prednisone and others);
- phenothiazines (Compazine and others);
- thyroid medicine (Synthroid and others);
- birth control pills and other hormones;
- medicines for colds or asthma
- seizure medications (Dilantin and others);
- diet pills, stimulants, or medicines to treat ADHD; or
- heart or blood pressure medicine such as amlodipine (Norvasc, Caduet, Exforge, Lotrel, Tekamlo, Tribenzor, Twynsta, Amturnide), diltiazem (Cartia, Cardizem), nifedipine (Nifedical, Procardia), verapamil (Calan, Covera, Isoptin, Verelan), and others.
Tell your doctor about all other medicines you use, especially:
- insulin; or
- an oral diabetes medication such as glipizide (Glucotrol, Metaglip), glimepiride (Amaryl, Avandaryl, Duetact), glyburide (DiaBeta, Micronase, Glucovance), and others.
This list is not complete and other drugs may affect your blood sugar or interact with acarbose. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.
