Glucotrol XL (glipizide extended release) is an oral diabetes medicine that helps control blood sugar levels used together with diet and exercise to treat type 2 (non-insulin dependent) diabetes. Glucotrol XL is available in generic form. Common side effects of Glucotrol XL include nausea, vomiting, loss of appetite, diarrhea, constipation, upset stomach, gas, dizziness, drowsiness, headache, weight gain, and skin rash, redness, or itching.

The usual starting dose of Glucotrol XL is 5 mg per day. Dosage adjustment is based on laboratory measures of glycemic control. Most patients are controlled with 5 mg to 10 mg taken once daily. Some patients may require up to the maximum daily dose of 20 mg. Hyperglycemia (high blood sugar) may result if you take Glucotrol XL with drugs that raise blood sugar, such as: isoniazid, diuretics (water pills), steroids, phenothiazines, thyroid medicine, birth control pills and other hormones, seizure medicines, diet pills, and medicines to treat asthma, colds or allergies. Hypoglycemia (low blood sugar) may result if you take Glucotrol XL with drugs that lower blood sugar, such as: non-steroidal anti-inflammatory drugs (NSAIDs), aspirin or other salicylates, sulfa drugs, monoamine oxidase inhibitors (MAOIs), beta-blockers, fluconazole, probenecid, or blood thinners. Glucotrol XL should be used only when prescribed during pregnancy. It is not recommended for use for at least one month before delivery due to the potential for harm to a fetus. Insulin may be preferred during pregnancy. Based on information from related drugs, this medication may pass into breast milk. Consult your doctor before breast-feeding.

Glucotrol XL Overview - Patient Information: Side Effects

SIDE EFFECTS: Nausea, vomiting, loss of appetite, diarrhea, constipation, upset stomach, gas, headache, and weight gain may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

An empty tablet shell may appear in your stool. This effect is harmless because your body has already absorbed the medication.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if you have any serious side effects, including: signs of infection (such as persistent sore throat, fever), easy bleeding/bruising, stomach pain, yellowing eyes/skin, dark urine, unusual tiredness/weakness, unusual/sudden weight gain, mental/mood changes, swelling hands/feet, seizures.

This medication can cause low blood sugar (hypoglycemia). This may occur if you do not consume enough calories from food or if you do unusually heavy exercise. Symptoms of low blood sugar include sudden sweating, shaking, fast heartbeat, hunger, blurred vision, dizziness, or tingling hands/feet. It is a good habit to carry glucose tablets or gel to treat low blood sugar. If you don't have these reliable forms of glucose, rapidly raise your blood sugar by eating a quick source of sugar such as table sugar, honey, or candy, or drink fruit juice or non-diet soda. Tell your doctor immediately about the reaction and the use of this product. To help prevent low blood sugar, eat meals on a regular schedule, and do not skip meals. Check with your doctor or pharmacist to find out what you should do if you miss a meal.

Symptoms of high blood sugar (hyperglycemia) include thirst, increased urination, confusion, drowsiness, flushing, rapid breathing, and fruity breath odor. If these symptoms occur, tell your doctor immediately. Your dosage may need to be increased.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

What is Prescribing information?

Glucotrol XL FDA Prescribing Information: Side Effects
(Adverse Reactions)

SIDE EFFECTS

The following serious adverse reactions are discussed in more detail below and elsewhere in the labeling:

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

In clinical trials, 580 patients from 31 to 87 years of age received GLUCOTROL XL in doses from 5 mg to 60 mg in both controlled and open trials. The dosages above 20 mg are not recommended dosages. In these trials, approximately 180 patients were treated with GLUCOTROL XL for at least 6 months.

Table 1 summarizes the incidence of adverse reactions, other than hypoglycemia, that were reported in pooled double-blind, placebo-controlled trials in ≥ 3% of GLUCOTROL XL-treated patients and more commonly than in patients who received placebo.

Table 1: Incidence (%) of Adverse Reactions Reported in ≥ 3% of Patients Treated in Placebo-Controlled Clinical Trials and More Commonly in Patients Treated with GLUCOTROL XL (Excluding Hypoglycemia)

  GLUCOTROL XL (%)
(N=278)
Placebo (%)
(N=69)
Adverse Effect
Dizziness 6.8 5.8
Diarrhea 5.4 0.0
Nervousness 3.6 2.9
Tremor 3.6 0.0
Flatulence 3.2 1.4

Hypoglycemia

Of the 580 patients that received GLUCOTROL XL in clinical trials, 3.4% had hypoglycemia documented by a blood-glucose measurement < 60 mg/dL and/or symptoms believed to be associated with hypoglycemia and 2.6% of patients discontinued for this reason. Hypoglycemia was not reported for any placebo patients.

Gastrointestinal Reactions

In clinical trials, the incidence of gastrointestinal (GI) side effects (nausea, vomiting, constipation, dyspepsia), occurred in less than 3% of GLUCOTROL XL-treated patients and were more common in GLUCOTROL XL-treated patients than those receiving placebo.

Dermatologic Reactions

In clinical trials, allergic skin reactions, i.e., urticaria occurred in less than 1.5% of treated patients and were more common in GLUCOTROL XL treated patients than those receiving placebo. These may be transient and may disappear despite continued use of glipizide XL; if skin reactions persist, the drug should be discontinued.

Laboratory Tests

Mild to moderate elevations of ALT, LDH, alkaline phosphatase, BUN and creatinine have been noted. The relationship of these abnormalities to glipizide is uncertain.

Postmarketing Experience

The following adverse reactions have been identified during post approval use of GLUCOTROL XL. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
