Generic venlafaxine HCL ER, like its brand-name counterpart, can cause various side effects. Common ones include nausea, dizziness, headache, drowsiness, constipation, and dry mouth. These usually lessen as your body adjusts to the medication.
More serious, though less frequent, side effects require immediate medical attention. These include suicidal thoughts or behaviors, seizures, allergic reactions (rash, hives, swelling), fast or irregular heartbeat, and high blood pressure. Report any of these immediately to your doctor.
Sexual side effects such as decreased libido or difficulty achieving orgasm are also possible. Discuss these concerns openly with your doctor; they may adjust your dosage or suggest alternative treatment strategies.
Withdrawal symptoms can occur if you stop taking venlafaxine HCL ER abruptly. Always follow your doctor’s instructions for gradually reducing your dosage to minimize withdrawal effects like anxiety, dizziness, nausea, and irritability.
