Yes, Modula 5 mg, which contains Sildenafil (the same active ingredient in Viagra), can potentially cause digestive issues as a side effect. Some individuals may experience mild gastrointestinal problems when taking sildenafil, including:

Indigestion (Dyspepsia): This is one of the more common side effects, causing discomfort in the upper abdomen, bloating, or a feeling of fullness after eating.

Nausea: Some people may feel nauseous after taking Modula 5 mg, which could be due to the medication's effects on the digestive system.

Diarrhea: Although less common, some people may experience diarrhea as a side effect of sildenafil.

Abdominal Pain: Mild stomach or abdominal discomfort can occur in some individuals.

Heartburn: Some people may experience acid reflux or heartburn as a result of sildenafil, which can lead to a burning sensation in the chest.

These side effects are generally mild and temporary. However, if you experience persistent or severe digestive issues, it is important to consult your doctor. They may recommend adjusting your dosage or trying an alternative medication.

Additionally, taking Modula with a heavy meal, particularly one high in fat, can increase the likelihood of gastrointestinal side effects and may also delay the medication’s effectiveness. To minimize this risk, consider taking Modula on an empty stomach or with a light meal.
